Remarkable results have been achieved in the research and demonstration of the technical model of green yield-increasing and efficiency-increasing soybean.

By returning straw to the field, the average yield per mu was 11.8%, and the efficiency was 183.7 yuan.

On September 21, the Chinese Academy of Agricultural Sciences held a "demonstration meeting on the green yield-increasing and efficiency-increasing technology model of Huang-Huai-Hai summer soybean in Suzhou City, Anhui Province." this paper focused on the effectiveness of the integration of eight key technologies such as no-tillage mulching and precision sowing of soybean wheat straw, and discussed and exchanged the next research and demonstration work. Li Jiayang, vice minister of agriculture and president of the Chinese Academy of Agricultural Sciences, attended and delivered a speech. Liu Yongchun, deputy secretary general of the Anhui Provincial people's Government, Ma Shuping, deputy director of the seed Administration of the Ministry of Agriculture, Wan Jianmin, vice president of the Chinese Academy of Agricultural Sciences, and Li Zhaohui, vice mayor of the Suzhou Municipal people's Government, attended the meeting. The meeting was presided over by Wang Hanzhong, vice president of the Chinese Academy of Agricultural Sciences.

Li Jiayang fully affirmed the remarkable results achieved since the implementation of the "demonstration model of green soybean production and efficiency" project. He said: it is very necessary to carry out a demonstration of the "green technology model for increasing production and efficiency of soybean". With the support of Anhui Province and Suzhou City and the coordinated promotion of brother units, through the construction and promotion of this technology model, it will greatly improve the soybean production level and planting efficiency in the Huang-Huai-Hai region, increase the enthusiasm of farmers to plant soybeans, and promote the sustainable development of China's soybean industry.

Li Jiayang pointed out that with the rapid economic development and the continuous improvement of people's living standards, the demand for soybeans in China is rising rapidly. However, due to the decline of comparative efficiency, the planting scale of soybean in China continues to decline, and the import continues to increase, which poses a serious challenge to China's food security, social stability and economic development. Under the severe situation that the constraints of cultivated land resources are becoming increasingly prominent and the planting area is difficult to continue to expand, a new model is formed from the study of grain and bean rotation, variety cultivation, agricultural machinery, plant protection and other aspects, which is expected to restore the supply capacity of soybeans and ensure the safety of edible protein in China.

Li Jiayang demanded that we should persist in the research and demonstration of the green model of increasing production and efficiency of soybeans for a long time, constantly intensify our work, sum up and improve it, and continue to promote it. First, strengthen organizational leadership. Implement the leading responsibility of the project hosting unit, take the initiative to dock with the Ministry of Agriculture and other superior departments, strive for local support and cooperation, and strengthen cooperation with brother units. The second is to build a joint system for tackling key problems. We will integrate the resources and advantages of governments and technical groups at all levels, such as the state, provinces, cities, and counties, carry out country-oriented collaborative innovation, and form a new pattern of agricultural scientific and technological innovation and achievements transformation that closely connects the upper, middle and lower reaches. The third is to strengthen technological integration and innovation. Based on the development needs of China's soybean industry, focusing on resource conservation and ecological friendliness, integrate the most advanced technological achievements at home and abroad, which are most suitable for regional development and most easily applied to production, and build a comprehensive technology model that runs through the whole process of production and can be replicated. lead the development of soybean industry in the future. The fourth is to establish a fixed test and demonstration base. In the main producing areas and typical ecological areas, a number of test and demonstration bases should be rationally arranged, and the demonstration sites with strong representativeness, good demonstration conditions, high local enthusiasm, and easy to learn and observe will be fixed for a long time, so as to become bigger and stronger, so as to radiate and promote the development of regional industries. Fifth, to carry out technical advisory services. Strengthen the research on the overall and strategic issues of the soybean industry, and provide advisory services for the strategic decision-making of superior departments. At the same time, we will strengthen technical training services for grass-roots agrotechnical personnel and new business entities such as large growers, farms, and professional associations, and establish a development model of "research and development, integration, demonstration, training and promotion". The sixth is to strengthen propaganda and guidance. Timely summarize and refine the good practices, good experiences, and good results in the pilot demonstration work, publicize and popularize mature technological models, and actively create a good atmosphere for relying on scientific and technological progress to promote agricultural production and efficiency.

It is reported that the project is chaired by Han Tianfu, a researcher at the Institute of Agricultural Sciences of the Chinese Academy of Agricultural Sciences. It integrates eight key technologies, such as no-tillage and straw-covered sowing of wheat stubble, new soybean varieties with high quality and high yield, soil testing and formula fertilization, integrated pest and disease control, safe application of herbicides, low-loss mechanical harvesting, quality monitoring and evaluation, and soybean food processing and utilization. According to the yield measured by the expert group, the soybean planted with this technical model has a yield of 195.3 kg per mu, which is 20.6 kg higher than that of the conventional method (174.7 kg), an increase of 11.8%, and a net income of 183.7 yuan per mu. At the same time, it also solved the problem of straw treatment, not only solved the long-term problems such as pollution caused by straw burning, but also realized the staggered utilization of straw through straw mulching and turned waste into treasure.

At the meeting, the signing ceremony of the industrialization cooperation agreement of "no-tillage straw covering precision seeder for wheat stubble land" was also held. Responsible persons from relevant departments of the Chinese Academy of Agricultural Sciences, Anhui Provincial Committee of Agriculture, Suzhou Academy of Agricultural Sciences, and relevant experts from the technical system of the national soybean industry attended the meeting.
