Wheat 657.2 kg, maize 860.3 kg, annual income increase of 1200 yuan
This website news On September 26, the Chinese Academy of Agricultural Sciences, together with the Shandong Academy of Agricultural Sciences, the Dezhou Academy of Agricultural Sciences and other member units of the wheat-maize science and technology innovation alliance collaboration group, jointly held at Wucheng County, Dezhou City, Shandong Province an on-site observation event for the research and demonstration of the annual wheat-maize green yield-and-efficiency-boosting technology model. Participants observed the maize demonstration site of the 100,000-mu demonstration area, listened to experts' introduction of the technology integration application results, and discussed the next work plan. Chen Mengshan, Party secretary of the Chinese Academy of Agricultural Sciences, and Wan Jianmin, vice president, Yang Lisheng, deputy inspector of the Science and Education Department of the Ministry of Agriculture, Ma Shuping, deputy director of the Seed Management Bureau, Liu Xin, deputy secretary of the National Agricultural Technology Extension Center, and others attended the meeting. The meeting was chaired by vice president Wang Hanzhong.
On behalf of the lead unit, Chen Mengshan announced that the first implementation project of the National Agricultural Science and Technology Innovation Alliance——the “Research and Demonstration of the Annual Wheat-Maize Green Yield-and-Efficiency-Boosting Technology Model”—had achieved complete success. The 100,000-mu wheat-maize core demonstration field reached an annual yield of 1517.5 kg per mu, of which wheat was 657.2 kg and maize 860.3 kg, exceeding the “one and a half tons of grain” research target, with an annual wheat-maize income increase of more than 1200 yuan, achieving green yield and efficiency increases.
Chen Mengshan pointed out that this year's research and demonstration work on the annual wheat-maize green yield-and-efficiency-boosting technology model achieved new breakthroughs, with obvious overall results, exciting outcomes, and very good prospects. First, during the demonstration process the intensity of technology integration was great, changing the situation of having technologies that were not matched and having technologies that were not integrated, with good technology transformation results, achieving the combination of technology with experts and technology with projects; the integrated technologies were not only said to be useful by experts, but, more importantly, said to be useful by farmers. Second, the cost-saving and efficiency-boosting results were obvious, the actual demonstration results were ideal, and the use of pesticides and chemical fertilizers was reduced. Third, the large-area demonstration results were good, showing that the technology is mature and stable, solidly implemented, and capable of large-area promotion and replication.
Chen Mengshan emphasized that the realization of the “one and a half tons of grain” green yield-boosting research target is the result of taking into account both green ecological benefits and economic benefits, strengthened confidence in scientific and technological innovation supporting agricultural transformation and upgrading, strengthened confidence in using the mechanism of the National Science and Technology Innovation Alliance to revitalize agricultural science and technology, effectively explained how scientific and technological work can be “grounded in reality while aiming high” and how it can solve major needs of national industrial development, and is of great significance for enhancing China's comprehensive grain production capacity, international competitiveness and sustainable development capacity.
Chen Mengshan required that next year's research work on the green yield-and-efficiency-boosting model should further improve its goals, further expand the demonstration of the “one and a half tons of grain” model, and, while achieving the “one and a half tons of grain” yield, achieve the “one control, two reductions, three basics” goals in development methods, while also achieving “innovation” in three aspects. First, continue to advance technological integration innovation. Further improve the green integration innovation of technology, continue to integrate new products and new technologies from relevant institutes of our academy, domestic sister units and internationally, enhance the advanced nature and international nature of the technology, focus on strengthening the integration innovation of “Internet + agriculture” technology, agricultural product processing technology and straw resource utilization technology, and research and develop integrated light and simplified technologies so that farmers can learn them and use them. Second, continue to promote work organization innovation. Through organizational innovation, upgrade the “Dezhou model”, closely follow major national industrial development needs, do a good job in top-level design, further clarify work goals, continuously improve and fully give play to the role of the academy-local cooperation office and the innovation alliance, promote the participation of cooperatives and new-type business entities, and provide reference and experience for green yield-and-efficiency-boosting models of other crops. Third, continue to promote extension and transformation innovation. Transform toward government departments, turning it into policy recommendations for their decision-making, to better serve national agricultural transformation and development; transform toward farmers, simplifying complex technologies, providing good service to farmers, and letting farmers understand and use them; transform toward scientific research units, bringing problems in actual production to scientific research units for scientists to answer, and continuously improving the disciplinary structure.
It is reported that the “Research and Demonstration of the Annual Wheat-Maize Green Yield-and-Efficiency-Boosting Technology Model” is a concrete action of the Chinese Academy of Agricultural Sciences to implement the Ministry of Agriculture's “one control, two reductions, three basics” development goals and to carry out the overall goals of structural adjustment and mode transformation in agricultural production in the new period, and is also the first implementation project of the National Agricultural Science and Technology Innovation Alliance. The Chinese Academy of Agricultural Sciences, the Shandong Academy of Agricultural Sciences and the Dezhou Academy of Agricultural Sciences signed in Beijing at the beginning of this year the agreement of the wheat-maize science and technology innovation alliance collaboration group, determined the research target of “one and a half tons of grain” per mu, formulated a practical and feasible implementation plan, and carried out coordinated research. On June 3, the wheat green yield-and-efficiency-boosting technology model demonstration was observed on site, integrating 8 key core technologies including excellent varieties with high-quality coated seeds, straw return to the field, deep loosening and no-tillage wide-width precision sowing, scientific fertilization, general irrigation of overwintering water, green prevention and control, full-process mechanization and full-process informatization, and building the technical model of “eight matching items of agricultural machinery and agronomy, four precisions of scientific fertilization, four combinations of green prevention and control”, achieving good green yield-and-efficiency-boosting results. According to expert yield measurement, the 1000-mu core area reached 728 kg per mu, and the 100,000-mu demonstration area averaged 657.2 kg per mu, more than 100 kg higher than the county average of 553.4 kg per mu. Through full-process mechanization, 5 labor units were saved per mu, saving about 400 yuan in costs; through green prevention and control, the occurrence of pests and diseases was effectively controlled, and the frequency and amount of pesticide use were reduced.
The maize green yield-and-efficiency-boosting technology model integrated 8 key technologies including excellent varieties with high-quality coated seeds, scientific sowing, green prevention and control, chemical control for stress resistance, timely late harvest, harvest and storage loss reduction, full-process mechanization and full-process informatization, and built the technical model of “eight matching items of agricultural machinery and agronomy, six integrations of scientific sowing, four combinations of green prevention and control”, achieving the expected goals of increasing yield by more than 10%, saving costs by more than 10%, increasing efficiency by more than 10%, and reducing pesticide and chemical fertilizer application by more than 10%.
