Smart Agriculture: professional sensors are a major bottleneck

the agricultural IOT expert group of the Ministry of Agriculture recently screened and released 310 achievements to the society, including sensing equipment, software systems, application modes, market-oriented solutions and typical cases, which have played a good demonstration role in the promotion and Application of the agricultural IOT

China's agricultural development is facing the constraints of resource shortage and environmental deterioration, and the contradiction between high input of resources and extensive management. There is an urgent need to achieve real-time monitoring of agricultural production process and improve the level of refined management. Agricultural IOT came into being. How is the agricultural IOT applied and what role does it play

what smart agriculture looks like

in the past, growing vegetables was based on experience, which was prone to miscalculation. Now it depends on instruments, and management is more scientific. In Tianjin Jinghai Shengbao farmers' cooperative, the demonstration site of the agricultural IOT regional pilot project of the Ministry of agriculture, the situation of dozens of vegetable greenhouses is concentrated on several computer screens, and dynamic curves record 24-hour information such as air and soil temperature and humidity in the greenhouses. Once necessary, it can also automatically or remotely control the implementation of irrigation, rolling curtains and other operations. Gu Jing, the chairman of the cooperative, is very satisfied with this set of IOT equipment: after the installation of the equipment, the base has reduced the labor demand by 20, and the labor cost can be saved by 600000 yuan a year

log in to the Tianjin Agricultural IOT platform, click on the production support sub platform, and the agricultural information of each IOT pilot is clearly displayed. The platform, developed by Tianjin in cooperation with the Chinese Academy of Sciences, covers 17 databases in agricultural production, market circulation and other fields, and realizes the collection of sensing data from 25 bases in the city. Without going to the land, you can master the breeding situation of the city's United cooperatives, and provide a basis for expert technical guidance and decision-making. Guan Hongyi, director of the information center of the market information office of the Tianjin Agricultural Commission, said

at the beginning of 2013, the State Council issued a document proposing to realize the scale demonstration application of IOT in many fields, including agriculture, by 2015. Since then, the Ministry of agriculture has implemented the regional pilot project of agricultural IOT in Tianjin, Shanghai and Anhui. According to the characteristics of their respective agricultural industries, the three places have carried out experiments and demonstrations in key areas, trying to explore and form a visible, usable and sustainable application mode of agricultural IOT, and promote it in different regions and stages throughout the country

agricultural IOT mainly realizes three functions: perception, transmission and control. Xushiwei, director of the Information Institute of the Chinese Academy of Agricultural Sciences, explained that we should not only perceive the publicity and implementation of new material standards, including environmental variables such as water, gas and light, but also perceive biological ontology. For example, the perception of various nutrients in rice leaves. If the chlorophyll content in rice leaves is perceived to be reduced, it indicates that there is a lack of nitrogen, so nitrogen fertilizer should be added. And when the naked eye sees that the leaves turn yellow, it is too late to apply fertilizer

Zhang synthetic, director of the Department of market and economic information of the Ministry of agriculture, said that transforming agriculture through IOT technology and improving the intelligence of all links will help to achieve measurable environment, controllable production and traceable quality

where is the bottleneck of the industry

two years ago, I saw a chlorophyll detection sensor in Israel. Now Chinese enterprises have begun to break the problem and have independent intellectual property rights in the development of detection sensors for biological ontology, including chlorophyll and leaf temperature. Yuxinrong, Vice Minister of the Ministry of agriculture, said that China's agricultural IOT has achieved rapid development and has been widely used. However, compared with other fields such as industry and commerce, it is still in its infancy, and the gap is obvious

zhaochunjiang, director of the national agricultural informatization engineering technology research center, said that the scale of agricultural IOT is small, and there is no business model for sustainable development. Key technologies and practical products need to be further strengthened. Specifically, the product price is relatively high, and the technical performance needs to be improved; The data of animals and plants are very stable, and the perception of life information needs to be strengthened; High throughput and low-cost communication technologies suitable for rural areas need to be strengthened; The mass production capacity of the product is insufficient, or it cannot be sold immediately after mass production

Capital investment is the primary problem that puzzles the development of agricultural IOT. In the case of low overall comparative benefits of agriculture and decentralized management of small farmers, the development of IOT is facing financial difficulties. Boswell, vice president of IOT Industry Association, believes that the pilot demonstration does not mean the real realization of industrialization, and large-scale commercial applications still need time. Agriculture is a weak industry with poor controllability of production conditions, which determines that the application of IOT in China's agricultural field is obviously different from that in industry and other fields, resulting in serious financial constraints in its early development

the price of a set of IOT equipment varies from 10000 yuan to hundreds of thousands Yuan due to different core sensors and different layout scales. At present, the IOT project in the pilot area adopts the input method of government subsidies and enterprise investment, and the input-output ratio of enterprises to IOT is different. Gu Jing said: the cooperative invested 1.1 million yuan in the IOT equipment of vegetable greenhouses, of which the government supported 700000 yuan and raised 400000 yuan by itself. It is expected that the cost raised by itself will be recovered in one year. But for enterprises, this part of the cost is still relatively high

some IOT equipment is not grounded enough, and it needs to continue to explore in meeting the use needs of farmers. At present, the research and development of agricultural IOT equipment in China are mostly from the laboratories of colleges and universities, and there are many conceptual products, which are quite different from the actual application of agriculture

the lack of special sensors for agriculture is also a bottleneck in the development of agricultural IOT in China. At present, the types of agricultural sensors in China account for less than 10% of the world, and there is still much room for improvement in coverage and applicability. The performance of some domestic sensors is not stable enough, which often needs to be corrected, and the service life of the equipment is short

Where is the development path

the agricultural IOT project should take the measurement, fast transmission, flexible calculation and good use as the construction standard, and focus on seeking breakthroughs in functional design, core technology, promotion mechanism and so on. Zhang said that we should strengthen independent innovation, strive to break through common technologies such as core chips and software of the agricultural IOT, break through key technologies such as smart sensors, and establish and improve the standard system of the agricultural IOT

to grasp the characteristics of agricultural IOT, we should clarify the three aspects of the development path. Yu Xinrong said that the agricultural system is a huge and complex system containing natural, social, economic and human activities. Only by adhering to the development path of full factors, full process and full system, and fully considering the whole growth period, the whole industrial chain and all related factors, can we promote the scientific development of agricultural IOT

compared with other fields, agricultural IOT has the characteristics of urgent demand and large number of beneficiaries. The scale of agricultural production is not high, and the investment capacity of production and operation entities is weak. The government needs to strengthen financial support, give a certain proportion of subsidies to the application of agricultural IOT, and stimulate the enthusiasm of production and operation entities. While strengthening external blood transfusion, enhancing the hematopoietic function of agricultural IOT enterprises has become a key factor for the sustainable development of agricultural IOT

Yu Xinrong said that it is impossible for the government to play a solo role in the development of agricultural IOT. Relying solely on financial funds is unsustainable, and the key is to rely on the strength of enterprises. We should strengthen mechanism innovation, encourage and support relevant scientific research institutions and enterprises to participate in the work of agricultural IOT, and speed up the formation of a promotion mechanism for government enterprise cooperation and market-oriented operation. At the same time, we should give better play to the supporting and leading role of the government, create a good development environment for enterprises, and make enterprises profitable

demand orientation is the key to solve the problem of agricultural IOT development, and there is no future without grounding. To be convenient, practical and stupid, Professor Li Daoliang, the head of Yixing agricultural IOT Research Center at China Agricultural University, said that taking the five-year experience of Yixing agricultural IOT aquaculture demonstration as an example, from the laboratory concept Jinan new era Gold Testing Instrument Co., Ltd. 4-ball friction testing machine: products under the specified load to the final mature application system, a total of three generations of products have been developed, including circuits, communications The three modules of the model have been improved hundreds of times, most of which are to adapt to the local environmental characteristics and farmers' requirements for simple operation

it is understood that the Ministry of agriculture is actively planning to launch the beneficial agricultural plan with financial support to systematically promote the construction of national agricultural production and operation informatization and information service system. At the same time, we are studying the establishment of agricultural information subsidy system, and accelerating the inclusion of agricultural IOT related products and equipment into the catalogue of agricultural machinery purchase subsidies, so as to encourage telecommunications operators, it agriculture related enterprises, scientific research institutions and other societies. The most important thing is the positive power of human transformation and upgrading, and gradually form the diversification of investment subjects under the guidance of the government, the marketization of operation and maintenance, and jointly promote the development of agricultural IOT
