Academician Wang Mahua

　　In field of agricultural engineering in our country，Wang Mahua, academician of the Chinese Academy of Engineering and professor of China Agricultural University, was mentioned，People in the industry feel very friendly，And not just because he's kind and approachable，In the domestic major academic forums to give a report, clear thinking, loud voice，What's more, he is a pioneer in the development of agricultural engineering disciplines in our country，Agricultural equipment and mechanization engineering development strategy research, agricultural electronic information and electrical automation engineering technology expert，It has made outstanding contribution to the development of agricultural engineering discipline and education in China, expanding international cooperation in Chinese agricultural engineering science and technology, and expanding international influence。

　　Wang Mahua was the vice chairman and chairman of the Chinese Society of Agricultural Engineering, and is currently the honorary chairman;He was the vice chairman of the Chinese Society of Agricultural Machinery, and is now the honorary chairman。He developed the field of agricultural application research of electronic information technology in our country，It is the pioneer and pilot expert of fine agricultural science and technology and demonstration research in China，A number of important scientific and technological innovation achievements have been made in the development strategy of fine agriculture, advanced sensing technology and system integration application, and agricultural information technology development，Presided over a number of major topics and projects。

　　Wang Mahua has visited more than 30 countries and regions in Europe, the United States, Asia and Africa to participate in international professional academic conferences, scientific and technological investigations and exchanges, and worked together to organize important international academic conferences and specially invited to give keynote reports。

　　Born in 1932, Wang Mahua is now 88 years old, but still hale and hearty, active in the field of agricultural engineering on the stage, keen to capture the new trends in the development of international agricultural engineering science and technology, and to serve the modernization of China's agriculture and rural development。Recently, the reporter walked into Wang Maohua's office and listened to his dedication and ardent expectations for the development of agricultural engineering in China。

　　Promote the development of agricultural engineering discipline and education

In 2004, the 7th National Member Congress and Academic annual meeting of the Chinese Society of Agricultural Engineering,Academician Wang Mahua was elected chairman of the Chinese Society of Agricultural Engineering

　　From 1985 to 2003, Wang Mahua served as a member and convener of the Academic Degree Committee of The State Council on the subject of "Agricultural Economics, Agricultural Mechanization" and "Agricultural engineering". He was also a member of the Teaching Steering Committee of National agricultural colleges and universities of the Ministry of Agriculture, deputy chairman and head of the agricultural engineering discipline。According to the development trend of agricultural engineering science and technology and education at home and abroad, he promoted the development of China's agricultural engineering discipline system structure that is suitable for China's national conditions and international scientific and technological development。In 1995, he was named an academician of the Chinese Academy of Engineering。In 2006, he was elected as an academician of the International Eurasian Academy of Sciences and a fellow of the International Association of Agricultural and Biological Systems Engineering。

　　Wang Mahua introduced that the world agricultural engineering discipline originated in the United States, in 1905, the United States J.B.Professor Davidson established the world's first department of agricultural engineering at Iowa State University, and started the training and education of scientific and technological talents in agricultural engineering in the United States, and he is also known as the "father of agricultural engineering in the world".。In the following century, the discipline of agricultural engineering developed rapidly worldwide。In 1999, the United States National Academy of Engineering and related academic organizations selected the 20 engineering science and technology achievements that made the greatest contribution to human society in the 20th century, of which electrification (including rural electrification) ranked first, and agricultural mechanization ranked seventh。

　　Wang Mahua said with emotion that the development of China's agricultural engineering discipline is rather tortuous。The first person to advocate the introduction of agricultural engineering technology into China was Mr. Zou Bingwen. In June 1944, Mr. Zou Bingwen, then vice Chairman of the Preparatory Committee of the Food and Agriculture Organization of the United Nations and the representative of the Chinese Ministry of Agriculture and Forestry in the United States, made a speech at the annual meeting of the American Society of Agricultural EngineersChina Needs Agricultural EngineeringSpeech of。On this basis, Mr. Zou is committed to promoting cooperation between Wanguo Agricultural Tools Company of the United States to help China cultivate agricultural engineering talents。In 1944, Wanguo Agricultural Tools Company reached an agreement with China to finance the establishment of agricultural engineering departments at Central University and Jinling University in Nanjing, China, and to send a group of college students to the United States for further study。

　　In the second half of the 1940s, nearly 20 college graduates in China were funded to study for a master's degree in agricultural engineering or further education in the United States, and most of these professionals became pioneers and founders of agricultural engineering science and technology education in China after returning home。In the 1950s, China's higher agricultural colleges sent more than 20 young teachers, undergraduate students and graduates to the Soviet Union to study, study or study for the associate doctorate degree in technical science, and became the backbone of the second generation of teaching and scientific research in China's agricultural engineering departments from 50 to 70 years, Wang Mahua is one of the scholars staying in the Soviet Union。

　　In the early 1950s, the national colleges and universities adjusted their departments, and the only two agricultural engineering departments of the former Nanjing Central University and Jinling University were merged to form the Department of Agricultural Mechanization of Nanjing Agricultural College。After more than 20 years, the development of China's agricultural engineering discipline is still relatively slow, until the National Science Conference held in 1978, clearly proposed that agricultural engineering discipline was included in the national key development of one of the 25 disciplines, agricultural engineering discipline to get on the track of rapid development。

　　In 1980, China established the Academic Degrees Committee of The State Council to coordinate and implement the training of high-level specialized personnel。At that time, a first-level discipline of agricultural mechanization and electrification was set up under the category of agriculture, and three second-level disciplines of agricultural mechanization, animal husbandry mechanization, and agricultural electrification were set up to train doctoral and master's students。

　　In February 1985, Wang Mahua was appointed as a member of the second discipline evaluation group of the Academic Degrees Committee of The State Council, and served as one of the convenors of the discipline evaluation group of "Agricultural economy and agricultural machinery". Since then, in order to open the process of establishing and improving the agricultural engineering discipline in China, Wang Mahua has concentrated a lot of efforts and efforts。

　　1985年冬，Commissioned by the Department of Science and Education of the Ministry of Agriculture, the Agricultural engineering discipline construction and postgraduate education seminar was held in Xiangshan Villa in Beijing，He invited the older generation of experts and scholars who studied agricultural engineering in the United States before the founding of New China to attend the meeting，Participating experts unanimously proposed，The name of the first-level discipline should be defined as "Agricultural Engineering"，Belong to engineering category，There are 12 secondary disciplines to train graduate students。This proposal has been approved by the Office of Academic Degrees Committee of The State Council, and important progress has been made in the adjustment of the structure of agricultural engineering discipline in China。

　　1987年，The Academic Degrees Committee of The State Council organizes argumentations and revisions of the catalogues of doctoral and master's degrees awarded by institutions of higher learning and scientific research institutions throughout the country，Wang Mahua was appointed as the leader of the revision group of the professional catalog of agricultural engineering discipline，He convened relevant experts and proposed agricultural engineering as a first-level discipline under the category of engineering，There are 8 recommendations for secondary disciplines，The programme was approved in 1990。

　　1996年，The Academic Degrees Committee of The State Council shall organize the second adjustment of the catalogue of disciplines and specialties，The principle of halving the number of secondary disciplines under the first-level disciplines of engineering is proposed，Wang Mahua and experts in related fields fully discussed and demonstrated the adjustment plan: the first-level discipline of agricultural engineering consists of agricultural mechanization engineering, agricultural soil and water engineering, agricultural biological environment and energy engineering, and agricultural electrification and automation。It was approved for implementation in 1997。

　　After continuous reform and adjustment, the discipline structure of agricultural engineering has been gradually improved and optimized, the internal unity of the discipline and the direction of discipline construction have been clear, and the discipline construction of agricultural engineering in colleges and universities across the country has entered a new period of rapid development。The agricultural engineering discipline of a number of schools has developed rapidly after obtaining the right to confer a doctor's degree, which has laid the foundation for the subsequent post-doctoral mobile station and the addition of national key disciplines, and created good conditions for the construction and development of the discipline。

　　1996年，In order to promote the reform of teaching content and curriculum system of national colleges and universities facing the 21st century，The National Board of Education has established a national expert Advisory group consisting of 17 experts，Wang Mahua was hired as an expert of the advisory group，He also presided over the project of "Research on the training Plan, Teaching Content and teaching system Reform for higher Agricultural Engineering Undergraduates in the 21st Century"。

Academician Wang Mahua participated in and presided over the major consulting project of the Chinese Academy of Engineering "Research on the Development Strategy of China's Agricultural Mechanization"

　　In strengthening the discipline platform construction, Wang Maohua has done a lot of effective work。He stressed that the development of China's agricultural engineering discipline must collect the strength of the national agricultural engineering scholars, give play to the wisdom of the national agricultural engineering scholars, and build a large team and a large platform。

　　Wang Maohua proposed to establish the "National Academic Seminar on the Construction and Teaching Reform of Agricultural Engineering and Related Disciplines in Colleges and Universities"，It has been held every two years since 1994，So far, 14 sessions have been held;The Annual Conference of the Chinese Society of Agricultural Engineering has been held every single year since 2005，It has been successfully held for 8 sessions。The academic conference and annual conference have become an important platform for academic discussion and exchange in the field of agricultural engineering in China, which has not only made a great contribution to promoting the development of the subject of agricultural engineering in our country, but also promoted the development of the subject of agricultural engineering in the organizer of the conference。

　　Today, Wang Mahua, who has entered the age of 80, has been concerned about the development of agricultural engineering since 2003, although he no longer serves as a member of the discipline evaluation group of the Academic Degrees Committee of The State Council。He said that the important problem facing the development of agricultural engineering discipline in China is the lack of research on the macro-strategy of modern agricultural development and the in-depth integration of engineering science and technology and biological system science and technology。Wang Mahua suggested that the first-level discipline "agricultural engineering" should follow the international development trend into the 21st century，Renamed "Agricultural and Biological Systems Engineering"，Agricultural equipment and mechanization engineering, agricultural soil and water engineering, agricultural information and electrical engineering, agricultural biological environment and biomass resource utilization engineering, agricultural food safety engineering and other secondary disciplines。

　　Wang Mahua stressed that agricultural and biological system engineering education should train agricultural and biological system engineers who serve the development of modern agriculture, and the essence of building new engineering talents who serve the modernization of agriculture is to train innovative talents。He suggested that attention should be paid to the research of changing the development mode of the subject，Condense the research direction of innovation，We will promote the close integration of production, learning, research and development，Advocate interdisciplinary collaborative innovation and interdisciplinary team cooperation，Focus on digital economy, bioeconomy and related industries，To improve scientific and technological innovation and advanced personnel training in agricultural and biological systems engineering in China。

　　Actively promote international exchanges and cooperation

In 2009, Academician Mahua Wang (front row, 2nd from left) attended the fourth Annual meeting of the Management Committee of the United Nations Asia-Pacific Centre for Agricultural Engineering and Machinery held in Thailand

　　Wang Mahua always stressed that scientific and technological workers engaged in agricultural engineering teaching and research should have an international vision, put the development of China's agricultural engineering discipline in the context of global economic integration to explore and study, and China's agricultural engineering discipline should learn the advanced experience of foreign countries, especially developed countries in the development of agricultural engineering。To this end, he actively participated in and promoted the strategy of "going out and inviting in" in the field of agricultural engineering, and actively carried out exchanges and cooperation with the world's agricultural engineering community。

　　Since the early 1980s，Wang Maohua actively organized domestic agricultural engineering scholars to go abroad for exchange and investigation，In particular, it participates in conferences of agricultural engineering disciplines in the United States, Europe and Asia，Under his guidance and drive，More and more Chinese agricultural engineering scholars appear on the forum of international agricultural engineering academic conferences，And Wang Mahua is often elected as a representative by domestic peers，Attended many important international academic conferences，And with excellent performance won the respect of international peers。Under the active coordination of Wang Mahua, in 1989, the Chinese Society of Agricultural Machinery and the Chinese Society of Agricultural Engineering formed the "Federation of Chinese Society of Agricultural Machinery and Agricultural Engineering", and joined the International Society of Agricultural and Biological Systems Engineering (CIGR) as a national member.。

　　1990年冬，时任北京农业工程大学（今中国农业大学东校区）副校长的汪懋华主动应国家教委选派，辞去副校长职务，毛遂自荐到位于泰国曼谷的“亚洲理工学院”（国际研究生院）任教。The academic atmosphere of the school is strong and the international exchange environment is open. During the teaching period, Wang Mahua often went to European and Asian countries to participate in various academic activities, which played a crucial role in establishing his influence among international peers, opening up an international vision, and participating in transnational academic exchanges and cooperation。

　　At the beginning of the 21st century, Wang Mahua actively participated in the establishment of the "Overseas Chinese Agricultural, Biological and Food Engineers Association", which was established in the United States in 2001. It is not only an organization for Chinese scholars in the agricultural engineering field at home and abroad to establish contacts and exchanges, but also an effective platform for domestic counterparts in international exchanges and cooperation。

　　The first subsidiary agency of the United Nations in China, the United Nations Asia-Pacific Centre for Agricultural Engineering and Machinery (now the United Nations Centre for Sustainable Agricultural Mechanization), signed an agreement on November 19, 2003 and settled in China，In the process，Mr. Wang did a lot of pushing，From 2003 to 2008, and from 2009 to 2012, he served as the Chinese member of the Technical Committee and the Chinese member of the Board of Directors of the Organization。

　　Inviting international agricultural engineering academic organizations to hold conferences in China is an important way to learn the development experience of agricultural engineering in developed countries. With the active striving and continuous efforts of Wang Mahua, many important international conferences on agricultural engineering have been held in China。

　　In 1989, China led the organization of the comprehensive international agricultural engineering conference held in Beijing, which was the first time that China hosted a large-scale international conference in the field of agricultural engineering. Wang Mahua served as the preparatory organizer and host of the conference。Russian agricultural engineering delegation more than 10 people, Israel high-end academic delegation 3 people, as well as China's Taiwan agricultural engineering community delegation also more than 10 people to participate in the conference, China's agricultural engineering community and many countries and regions of agricultural engineering academic organizations increasingly profound exchanges。

　　In 2004, CIGR's quadrennial International Agricultural Engineering Academic Conference was held in Beijing for the first time, and Wang Mahua served as the chairman of the conference。In terms of scale, level, number of participants from different countries and academic influence, the conference exceeded the previous CIGR academic conferences, and greatly expanded the international influence of China's agricultural engineering community。

　　In September 2014, the 18th CIGR World Congress was held in Beijing, where nearly 2,000 agricultural engineering scientists from around the world discussed how to promote the sustainable progress of global agricultural and biological systems engineering and improve the quality of human life。This time, China has dedicated a more wonderful international event to the world。

　　In view of the great contribution Wang Mahua has made to the development of agricultural engineering in China and its influence in the international field of agricultural engineering，Many important international agricultural engineering organizations invited and elected him to hold important positions in them，He is a member of the Food and Agriculture Organization of the United Nations Agricultural Engineering Expert Group, a member of the International Agricultural Mechanization Development Strategy Research Club in Bologna, Italy, and a deputy Chairman of the CIGR Agricultural Electrification and Energy Council。

　　1988年，Wang Mahua was recognized as the only member of the British Agricultural Engineers Association in China;In 2006, he was named academician of the International Eurasian Academy of Sciences.CIGR at its 16th World Congress in Bonn, Germany, 2006，Wang Mahua was awarded the title of the only member in China;The year 2010，CIGR 17th World Congress，Won the Outstanding Contribution Award;The year 2014，He became a founding member of the International Academy of Agricultural and Biological Systems Engineering (iAABE)。In addition, Mahua Wang has also been absorbed as a life member of the Asian Association of Agricultural Engineers, a member of the European Association of Agricultural Engineers, a member of the American Society of Agricultural Engineers, and has been employed as the consulting editorial board of several international academic journals。

　　From the 1980s, when China's agricultural engineering discipline began to contact with various international organizations, to 2010, when the headquarters of the Asian Society of Agricultural Engineering moved from Bangkok to Beijing, and Chinese scholars became the president of CIGR, the internationalization of China's agricultural engineering discipline has made remarkable achievements。In recent years, Chinese agricultural engineering scholars have repeatedly won awards from international organizations, and the discourse power and role of international organizations in the agricultural engineering field have been enhanced, which also indicates the new trend of the transfer of the world agricultural engineering center to Asia and the Asian agricultural engineering center to China。

　　The pioneer of fine agriculture research in China

In 2005, the "Third International Academic Conference on Intelligent Agricultural Information Technology" was held in Beijing. Academician Wang Mahua served as the director of the academic committee and made a keynote speech

　　Since the beginning of 1994, some advanced countries in the world have carried out research on fine agricultural technology。That period，Wang Mahua during an international academic exchange visit，Met a group of European and American scientists engaged in the integration of information technology and sustainable agricultural development，Start to study the global satellite positioning system (GPS), global satellite remote sensing system (RS), geographic information system (GIS) and agricultural equipment enterprises research and development of related products，He was acutely aware，Fine agriculture is a modern agricultural production mode and technical system to obtain "high yield, high quality and high efficiency" of farmland，Represents the new trend of modern agricultural development，It will become an important field of integration and development of the new generation of information technology and agricultural biological systems engineering。

　　In 1994, Wang Mahua began to lead the team to organize the theoretical exploration, demonstration practice and industrialization technology research and development of fine agriculture，At the same time with the international, he began to focus on the research field of fine agricultural information technology and system integration，In 1998, he presided over the establishment of the Fine Agriculture Research Center at China Agricultural University，The research progress of related engineering technology and system integration technology in developed countries is introduced，Promote and directly participate in the early practice of fine agriculture demonstration application in our country。

　　In September 1998, at the academic annual meeting of China Association for Science and Technology, Wang Mahua made a report entitled "Fine Farming - Intensive Farmland Cultivation Technology in the era of Knowledge Economy", which was the first time he publicly proposed the basic concept of fine agriculture and the trend of innovative practice in developed countries。He also published many series of papers on fine agriculture, elaborating the concept, connotation, characteristics, technical system, development roadmap and development direction of fine agriculture, which laid the theoretical foundation for the development of fine agriculture in China。

　　In March 1999, the "Beijing Precision Agriculture Demonstration Project" was approved and supported by the State Development Planning Commission。During the implementation of the project, the technical path of "first introduction, absorption and then innovation" proposed by Wang Maohua was adopted。In October 1999, Wang Mahua organized a delegation to the United States to investigate fine agriculture and related equipment manufacturing enterprises, after which his team fully participated in the planning and implementation of the demonstration project, focusing on the base of basic data sampling mapping and the introduction of foreign fine agricultural technology and equipment digestion and absorption work。

　　The Key Laboratory of "Modern Fine Agriculture System Integration Research" of the Ministry of Education was officially approved in January 2002, and he served as the director of the academic committee of the laboratory。In 2011, he applied for the establishment of the Key Laboratory of Agricultural Information Acquisition Technology of the Ministry of Agriculture (now the Ministry of Agriculture and Rural Affairs). In addition to serving as the director of the academic committee of the laboratory, Wang Mahua also served as the director of the academic committee of the agricultural information Technology subject group and other 3 key laboratories。In addition, Wang Mahua also participated in the construction of the facility agriculture subject group of the Ministry of Agriculture (now the Ministry of Agriculture and Rural Affairs), serving as the director of the academic committee so far, helping the subject group to carry out scientific research planning, subject setting and concise innovative research direction。

　　Wang Maohua actively promotes the support of science and technology authorities for fine agriculture。From the Tenth Five-Year Plan to the Twelfth Five-Year Plan，The state department of science and technology has given high support to the development of fine agriculture in our country.meanwhile，"Agricultural precision operation and informatization" has been identified as the priority theme of agricultural science and technology development in the Outline of the National Medium - and Long-term Scientific and Technological Development Plan (2006-2020)，From the aspects of national science and technology policy, the development of fine agriculture in China is ensured。

2007年，Academician Wang Mahua考察日本农林研究机构无线传感器网络技术研究进展

　　For many people, the term "Precision Agriculture" or "Precision Farming" is translated as "precision agriculture".，汪懋华坦率地说，From an academic point of view，The term "precision agriculture" is unscientific，The problem with agriculture is not simply to be technically accurate。

　　He believes that fine agriculture should be a technical system to enhance industrial efficiency in the era of information technology, help human beings make more reasonable use of agricultural resources, achieve sustainable development, and improve the level of industrial science and technology management, and is an integrated system assembled by different technologies。Not only should we consider the technical problems, but also consider the degree of social and economic development in different regions, and then decide how to assemble this technical system to ensure that this technology is both useful and can meet the sustainable development of the industry, but also consider the social and economic benefits of agriculture and sustainable development conditions。

　　It is precisely under the strategic vision of Wang Mahua's judgment and the unremitting efforts of the team that the applied research and development of the domestic fine agricultural technology system has basically kept pace with the international。From the introduction of concepts, development strategies, technical routes, research practices, to projects, bases, and talent construction, Wang Mahua has made important contributions to shorten the gap between China's fine agriculture and developed countries, and has played an important role in promoting the development of modern agriculture in China。In 2007, the "Precision Agriculture Key Technology Research and Demonstration" project organized by Beijing Academy of Agriculture and Forestry Sciences won the second prize of National Science and Technology Progress Award (Wang was the second winner).。

　　Promote the application of the Internet of Things in the field of agriculture and the evolution of fine agriculture to smart agriculture

Opening ceremony of the International Symposium on Agricultural Applications of Wireless Sensor Networks 2010

　　Since January 2010, Wang Mahua has presided over two strategic consulting research projects on agricultural application of the Internet of Things initiated by the Chinese Academy of Engineering。One is the "Internet of Things Development strategic planning Research" project supported by the National Development and Reform Commission fine agriculture and animal husbandry application sub-topic, the other is the Chinese Academy of Engineering project "Internet of Things in various important fields of application" agricultural application sub-topic。

　　The project approved by the Chinese Academy of Engineering clearly lists agriculture as one of the key research areas of the application of the Internet of Things, and proposes that the agricultural Internet of Things should be application-oriented to cultivate emerging industries。In that year, the Key Laboratory of the Ministry of Education of "Modern Fine Agriculture System Integration Research" of China Agricultural University held the "International Seminar on Wireless Sensor Network Agricultural Application", becoming the first research institution to study the application of Internet of Things technology in agriculture。

　　In January 2013, The General Office of the State Council issued a document on the development of the Internet of Things。Wang Mahua realized that the development potential of Internet of Things technology is huge, and there is a lot of room for development in the agricultural field。The focus of agricultural iot technology research should be advanced sensing technology for agricultural resources, environment, production process and food supply chain traceability, wireless sensor network communication technology and intelligent application technology of modern agricultural equipment。Wang Mahua believes that the Internet of Things is an important part of the country to promote the development of strategic emerging industries, is to support the transformation of economic development mode of service, agricultural iot applications should focus on resources, environment, production, agricultural products and food, agricultural equipment in the field of technological innovation research。

　　After several years of practice，Wang Mahua summarized the technologies and products that need to be broken through in the application of the Internet of Things in agriculture into five points: First, adhere to the perception as the main line to promote the development of the agricultural application of the Internet of Things;Second, vigorously promote the agricultural application research of wireless sensor network;Third, focus on the study of agricultural Internet of things application service model;The fourth is to vigorously cultivate information technology for agricultural cold chain logistics industry service, agricultural materials and agricultural products trading market service Internet of things application technology;Fifth, strengthen research on agricultural Internet of Things technology standards。

　　At the end of 2008, International Business Machines Corporation (IBM) proposed the concept of building a "smart Earth" to the U.S. government, and it has since been listed as a national strategy by the United States and other developed countries。Subsequently, the word "wisdom" has been widely used in promoting the transformation and upgrading of traditional industries, the development of the service economy and the capacity building of public services。

　　"Smart agriculture" is a new concept that leads the sustainable development of agriculture under the background of the rapid development of a new generation of information technology。2010年，The Food and Agriculture Organization of the United Nations publishes a report on Climate-Smart Agriculture (over 570 pages).，It covers land and water resources for agriculture, energy, conservation and sustainable use of genetic resources, intelligent management of crop production, animal husbandry, forestry, aquaculture systems and food supply chain systems，As well as policy, finance, disaster risk warning and capacity building。

　　Wang Maohua combined the characteristics of new technology development in the world at that time and the needs of China's agricultural transformation and upgrading，Put forward the idea of actively developing smart agriculture，We will vigorously promote the evolution of sophisticated agriculture to smart agriculture，To become a pioneer in the field of smart agriculture in China，He is also the initiator, chairman and keynote speaker of the first International Symposium on Smart Agriculture。

In 2012, Academician Wang Mahua (center) and Professor Nick Sigrimis of Athens Agricultural University in Greece investigated the production of solar greenhouse in China

　　Smart agriculture is the integration of a new generation of information technology and agricultural equipment technology，Combine the knowledge, experience and wisdom of agricultural managers and advanced producers and operators，To realize the scientific perception, analysis, regulation and intelligent management decision of agricultural production environment and production process information，It provides a new form of agricultural production and management with fine planting, visual management and intelligent decision-making for agricultural production。

　　Wang Mahua believes，Smart agriculture not only needs to be supported by faster, more accurate, lower cost and diversified information sharing service mechanisms，The analysis of agricultural and biological resources, environment, ecology and socio-economic conditions in different regions is also carried out.At the same time, he is good at using the wisdom of production managers to make good use of objective data information，Make scientific, cost-saving and efficient management decisions。These unique and profound understanding have become the driving force and support for him to promote the evolution of China's agriculture from fine agriculture to smart agriculture。

　　For the understanding of smart agriculture, Wang Mahua believes that there are two important dimensions: one is the technical dimension, and the other is the goal dimension。In the technical dimension，The construction of a smart agricultural system requires the integration of the Internet of Things, mobile Internet, cloud computing and big data service platforms to acquire, gather and process objective data related to agricultural production，At the same time, the experience and wisdom of agricultural production management personnel are deeply integrated to make scientific production and operation management, control and decision-making。In the goal dimension，Smart agriculture will improve the quality and efficiency of agricultural production and increase farmers' income，We will pursue innovative, coordinated, green, open and shared development，Ensure the safety of agricultural products and accelerate the modernization of agriculture as the goal，That is to maximize the comprehensive benefits of agricultural output, farmers' economic income and green ecological maintenance。

　　Wang Mahua pointed out that with the continuous development of science and technology, "sense of cloud wisdom" has gradually become a new feature of the development of information and communication technology (ICT), "sense" refers to the perception system, "move" refers to mobile communication and mobile Internet, "cloud" refers to cloud computing, "big" refers to big data, "wisdom" refers to wisdom and intelligence。

　　Smart agriculture is an integrated system based on the deep integration and development of the new generation of ICT technology and agricultural and rural modernization。"Wang Mahua said，With population growth, resource constraints and environmental degradation，Any technology that can effectively improve the utilization rate of agricultural soil, water, fertilizer, medicine, light, heat resources and green ecological environment protection，It will become a new hot spot in the development of smart agriculture.It is necessary to manage complex agricultural systems based on information and wisdom，We will promote IT application in agriculture and rural areas，Promote digitalization, networking, intelligence and intelligence，Transform the mode of agricultural development，Improving land yield, resource utilization and labor productivity;Promote the cross-integration of different disciplines to innovate research and development methods，Step into the digital economy era of high-quality agricultural and rural development of the frontier。
