　　"Nearly 600 acres of wheat I planted have been harvested, and the average yield per mu has reached about 550 kg, which is another harvest year." Han Xinbo, a large grain-growing household in Gaocheng District, Shijiazhuang City, Hebei Province, was very happy. The bumper harvest of summer grain has added confidence and confidence to food security and to hold the rice bowl.

　　The reporter learned from the Ministry of Agriculture and Rural Affairs that as of now, the country has harvested 305 million mu of winter wheat, the large-scale wheat harvest is basically over, the harvest rate is 97%, and the national summer grain harvest has reached 90%. According to the agricultural situation regulation and expert field investigation and analysis of the Ministry of Agriculture and Rural Affairs, this year's summer grain area is stable and yields have increased, and a bumper harvest is a foregone conclusion.

　　In the major wheat-producing regions of the country, various regions have worked hard to overcome the impact of the epidemic, and have been busy. They have shown the "foundation" of stabilizing the "Chinese rice bowl". Behind the golden harvest picture is the "hard core" of agricultural technology.

Breeding technology guarantees summer grain harvest

　　"The 26 new wheat I planted has a yield of at least 600 kilograms per mu." Lin Huaming's face in Yicheng District, Zhumadian City, Henan Province was full of joy in the harvest.

　　Xinmai 26 is a super-strong gluten wheat variety. With a series of advantages such as lodging resistance, high temperature resistance at a later stage, fast filling speed, high quality and high yield, it has not only been favored by farmers, but also sought after by grain purchase companies.

　　In addition to Xinmai 26, this year's national wheat industry technology system also announced three super-strong gluten varieties such as Jimai 44, Shiluan 02-1 and Jimai 229. Super gluten wheat can replace imported wheat.

　　Xiao Shihe, Chief Scientist of the National Wheat Industry Technology System, said: "China's wheat production technology is at an internationally advanced level, and the average yield growth rate in the past 20 years is leading in the world. Breeding has made a huge contribution. Since 2003, the wheat planting area has increased by less than 8%, and the yield has increased. The total output increased by 54.7%, and the increase in unit output contributed 84% to the increase in total output."

　　Minister of Agriculture and Rural Affairs Han Changfu said that this year the wheat harvest is good, there are three improvements: First, the yield is increased, it is expected that the average yield per mu can be increased by 4 kilograms; Second, the quality is improved, the grain is full, and the first and second class wheat are significantly increased; Third, the special wheat The proportion increased, and the proportion of strong gluten and weak gluten wheat increased by 2.8 percentage points from the previous year.

　　Under the unfavorable conditions of the new coronary pneumonia outbreak superimposed by frequent extreme weather, the excellent varieties have played a very important role in supporting the summer grain harvest.

"Cloud" farming together online guidance

　　Wang Lingli is an agricultural professional manager of Yangliu Land Stock Cooperative in Chongzhou Urban Agricultural Industrial Function Zone, Chengdu City. He manages 3,850 mu of land in the cooperative. In the critical stage of turning green seedlings of winter wheat, it is her main task to check seedling condition, disease condition and insect condition.

　　With a smartphone in hand and a "field management map" in front of him, Zhinong MAP became Wang Lingli's new helper in farming this year. "During the epidemic, when I opened Zhinong MAP at home, I could see the whole field, and the wheat growth was clear at a glance," she said.

　　More and more farmers began to try "cloud" farming, and experts also began to test the technical guidance on the waterline. Experts from various parts of the wheat industry technology system, together with grassroots agricultural technicians, family farmers, and large wheat growers, have established WeChat groups and QQ information communication platforms to timely understand production problems and provide comprehensive technical solutions. Since February this year, in order to ensure uninterrupted technical guidance for wheat production, the National Wheat Industry Technical System has produced more than 70 training courseware and short video programs, which have been broadcast on various media to promote wheat mid- and late-stage management techniques.

　　In addition, the accurate forecast of major pests and diseases also escorted the summer harvest. Academician Kang Zhensheng of Northwest A&F University led the national wheat industry technology system strip rust prevention and control team to keep abreast of strip rust occurrence trends and provide control suggestions to the competent agricultural department. "If it were not for the early warning of wheat stripe rust, I don't know if stripe rust happened so early this year." Zhou Kunyun, a wheat grower in Shabanqiao Village, Jingzhou, Hubei, said that 5 acres of wheat fields have appeared in the 230 acres he contracted. Large areas of disease, and sporadic infections in other wheat fields. Fortunately, timely prevention and control were carried out without causing major losses.

Weaving an efficient technology support network

　　Today, with 93 teams of the national wheat industry technology system as the core, the national modern agricultural industry technology system improves the high wheat production capacity and quality from the aspects of variety recommendation, planting technology, pest control, water and fertilizer management, harvest storage and processing, etc. Xialiangfengshuo has created an efficient and powerful technology support network.

　　Liao Xiyuan, director of the Department of Science, Technology and Education of the Ministry of Agriculture and Rural Affairs, said that the national modern agricultural industry technology system jointly constructed by the Ministry of Finance and the Ministry of Agriculture and Rural Affairs covers 50 agricultural products such as wheat, rice, pigs, and vegetables, and steadily supports a full range of coverage. The industrial science and technology team that is supported around the clock and devoted wholeheartedly has become the most direct and reliable strategic scientific and technological support for the development of modern agriculture.

　　"Next, we will effectively build on the national modern agricultural industry technology system, build a number of demonstration counties and villages and towns led by science and technology, build 100 modern agricultural science and technology demonstration demonstration bases, and vigorously promote the integration of agricultural machinery and agronomy, matching of good varieties and good laws, and production. Ecological coordination ensures high quality, green and environmental protection on the basis of high yield, and provides a more solid scientific and technological support for high-quality food security." Liao Xiyuan said.
