In the past half century, no technology can profoundly and widely affect human recognition like information technology. The ability to understand the world, transform the world, and promote industrial innovation. The word "wisdom" embodies the achievements of information technology. Today, this technological force has penetrated deeply into the agricultural field and formed the emerging form of smart agriculture .
From July 28th to 29th, the 2018 China Engineering Science and Technology Forum-Smart Agriculture Forum hosted by the Chinese Academy of Engineering, sponsored by the Institute of Agricultural Resources and Regional Planning of the Chinese Academy of Agricultural Sciences, the National Intelligent Agriculture Technology Innovation Alliance, and Beijing Hezhong Shuangzhuang Technology Co., Ltd. Held. Participants shared the latest research progress of smart agriculture, explored the opportunities and challenges faced by smart agricultural science and technology innovation in the future, and promoted the development and application of smart agriculture in China to better serve the rural revitalization strategy and agricultural and rural modernization.
Service Village Revitalization Strategy
At the end of the last century, the concept of digital earth was proposed. As an upgraded version of the digital earth, the smart earth is marked by digitization, networking, and intelligence, which is the general trend of future development.
"At present, the digital economy is becoming a new hot spot in the development of global science and technology, a new engine of economic growth, and a new height of international competition. The report of the 19th National Congress of the Communist Party of China emphasized in particular the need to build a digital China and promote the Internet, big data, artificial intelligence and The deep integration of the real economy. "Tang Huajun, chairman of the forum, academician of the Chinese Academy of Engineering and president of the Chinese Academy of Agricultural Sciences, said at the forum.
The field of traditional agriculture has also entered the digital era, and it is urgent to inject the power of "wisdom". So, what is smart agriculture? Zhao Chunjiang, academician of the Chinese Academy of Engineering and director of the National Engineering Research Center for Agricultural Information Technology believes that its characteristics include the deep integration of modern information technology and agriculture, advanced production tools (intelligent equipment), high quality, high efficiency, high efficiency and convenience Fast and user-friendly, safety and risk can be controlled independently.
The United States is moving towards Data Directed Agriculture based on digital information. In December 2017, the European Agricultural Machinery Association proposed at its summit that the era of agricultural digital technology revolution is coming, and the future development direction of European agriculture is Farming 4.0 (modern information technology + intelligent agricultural machinery equipment).
In China, the development of smart agriculture has been included in the outline of the "13th Five-Year Plan" for national economic and social development. The Central Government Document No. 1 in the past three years has mentioned vigorously developing digital agriculture and implementing smart agricultural projects.
According to the researcher of the former Deputy Director-General of the Food and Agriculture Organization of the United Nations (FAO), He Changchui, smart agriculture is just the right time. "From the perspective of the stage of socialist development with Chinese characteristics, smart agriculture is an important foundation for a digital China and a smart society; smart agriculture combines the characteristics of the farming society, the industrial society, and the information society to become the sixth industry, which is a strategy for the revitalization of China's agriculture and countryside Pushing hands. "He said.
Sun Tan, director and researcher of the Institute of Agricultural Information of the Chinese Academy of Agricultural Sciences, believes that government, research and industry cooperation will promote the deep integration of the Internet, big data and artificial intelligence with agriculture, and build a smart agricultural industry chain , information chain and data chain. Optimal solution for rural revitalization strategy.
Tang Huajun said that smart agriculture is an important part of the construction of digital China. Accelerating the development of smart agriculture and advancing the digital, networked, and intelligent transformation of the entire process of agriculture and rural areas will help promote production savings, optimize the allocation of elements, match supply and demand, and precise and efficient governance, and help promote the quality of agricultural and rural development Reform, efficiency change and dynamic change better serve our country's rural revitalization strategy and the modernization of agriculture and rural areas.
Exploration of the Practice of Smart Agriculture
Smell the rice? Yes, this is a result of the independent research and development of the smart agriculture innovation team of the Institute of Agricultural Resources and Regional Planning of the Chinese Academy of Agricultural Sciences-crop odor sensor.
Researcher Wu Wenbin, chief scientist of the team, introduced that volatile organic compounds are the "chemical language" of plants. The team combined new-type nanomaterial preparation technology and MEMS technology to develop a new crop volatile organic compound sensor array to monitor and obtain crop physiological information in real time; developed a high-sensitivity and low-cost rice aroma sensor for rice quality classification.
This is just one case in the practice of smart agriculture. Wu Wenbin also introduced the application of smart agriculture driven by big data of sky and ground, and described the applications of space remote sensing observation, aerial remote sensing observation, and ground IoT observation in farmland and orchard sensing, diagnosis, and decision-making. Yield prediction, growth monitoring, and pest control provide accurate solutions.
"The two areas where artificial intelligence is advancing rapidly in smart meteorology, one is the processing and analysis of observation information, and the other is to improve the timeliness and accuracy of forecasts." Researcher Xu Xiaofeng of the State Meteorological Administration believes that in order to improve the capacity and level of meteorological operations, Efforts to develop intelligent weather with artificial intelligence as its main feature are a worthwhile approach.
As early as four years ago, agricultural drones were named the top ten most breakthrough technological innovations in 2014 by MIT. Luo Xiwen, a member of the Chinese Academy of Engineering and a professor of South China Agricultural University, said that South China Agricultural University successfully researched the low-altitude remote sensing platform for rice information acquisition. And aviation plant protection is playing its irreplaceable role in the agricultural field.
At high altitudes (20 ~ 100 kilometers) where satellites do not come, and airplanes do not go, Professor Li Qingquan, the president of Shenzhen University, is studying the aerodromes, mooring drones and other resident platforms. "The intelligent sensing technology of spatial information is an important support for smart agriculture. The resident platform can be used for dedicated environmental sensing, providing new ideas for disaster monitoring and rural planning such as landslides and debris flows." He said.
Chen Xuegeng, an academician of the Chinese Academy of Engineering and a professor at Shihezi University, introduced Beidou Navigation to help the development of precision agriculture in Xinjiang. He believes that the development of precision agriculture should pay particular attention to the application of information technology to improve the design and manufacturing level of agricultural equipment and the management level of agricultural mechanization.
Automatic operation + variable control. In Xinjiang, one out of every three agricultural machines uses the "Hui Nong" Beidou navigation agricultural machine automatic driving system developed by Beijing Hezhong Shuangzhuang Technology Co., Ltd. "The future development of agriculture is closely related to human cognition of space and time. The stronger people's ability to control space and time, the broader the stage of agricultural development and the smarter agriculture." Guo Xinping, chairman of the company, said.
Thinking about the future from multiple perspectives
Research and Markets predicts that by 2025, the global market value of smart agriculture will be US $ 68.389 billion, with applications including precision agriculture, livestock and poultry monitoring, smart aquaculture, and smart greenhouses .
Deng Xiuxin, vice president of the Chinese Academy of Engineering, said at the opening ceremony of the forum that China is currently in the stage of transition from traditional agriculture to modern agriculture , and research on smart agriculture is also in its preliminary stage. Combining their respective research fields, the experts put forward thoughts on the development of smart agriculture in the future.
"There is no doubt that the facility and horticulture industry is developing intelligently, but the path to truly forming a facility with intelligent horticulture is still very long. We cannot call the entire industrial chain a little intelligent as intelligent facility horticulture." Academicians of the Chinese Academy of Engineering, Said Li Tian, a professor at Shenyang Agricultural University.
Professor Gong Ke of Nankai University agrees with this view, "The intelligent demand arising from China's economic and social transformation and upgrading is an endogenous driving force for intelligent technology and economic development. However, we cannot put everything on the label of" smart ", but We must refine practical problems and solve them scientifically. "
Wang Hua, an academician of the Chinese Academy of Engineering and a professor at China Agricultural University, said, "What we are facing is the problem of building a modern agricultural industrial system, and it is not just a simple application and stacking of technology. In addition to understanding the basic principles and methods of basic science, We must be good at handling the integration, selection, and optimization of multiple elements such as science, technology, economics, management, society, and the environment. "
It is undeniable that there are still some shortcomings in the development of smart agriculture in China, such as the lack of wisdom in the agricultural Internet of Things , high and unstable agricultural sensor investment, and weak process control and overall management capabilities. In addition, core technologies such as sensing technology, smart chips, models, algorithms, software and operating systems should adhere to independent innovation.
In terms of aviation technology development, Chen Xuegeng suggested that we should further explore the development model of China's agricultural aviation, strengthen the formulation of technical standards and specifications, strengthen the collaborative innovation research on key technologies, strengthen the promotion and application of technology, explore its application carriers, and apply policies. stand by.
Letting the data “flow” is also a suggestion made by many industry, university and research personnel. He Changchai believes that we should stick to application orientation and release data dividends. "Establish a center of excellence in the application of integrated data for smart agriculture, realize data sharing in the true sense, facilitate data compounding, supercomputing and big data mining, and serve ecological agriculture , new rural construction, and ecological civilization construction," he said.
Ruan Huaijun, director and researcher of the Institute of Science and Technology Information of the Shandong Academy of Agricultural Sciences, proposed that while researching and developing smart agricultural technologies and systems, we should also pay attention to the development of public scientific research services to allow rural farmers to share the results of smart agricultural science and technology innovation.
