[Strive for a new journey and make contributions to a new era] "The report of the 20th National Congress of the Communist Party of China made a strategic plan to accelerate the construction of a powerful agricultural country." Between the lines of the report of the 20th National Congress of the Communist Party of China (CPC), he felt that the CPC Central Committee attached great importance to food security and agricultural science and technology, and felt the confidence and confidence to firmly hold the Chinese people's jobs in their own hands. The report of the 20th National Congress of the Communist Party of China proposed to consolidate the foundation of food security in an all-round way and firmly hold the red line of 1.8 billion mu of arable land. Yang Wenyu said with deep feeling that since the 18th National Congress of the Communist Party of China, China has made major breakthroughs in food security and scientific and technological innovation, and accelerated the self-reliance of high-level agricultural science and technology and the modernization of agriculture and rural areas. Rice waves fluctuate with the wind, and corn is growing happily. The prospect of a bumper harvest can be seen everywhere in China, indicating that the CPC Central Committee has led hundreds of millions of people to walk a path of food security with Chinese characteristics. "In recent years, one of my major feelings is that traditional agriculture has accelerated its transformation and upgrading, which is driven by the empowerment of digital agriculture and smart agriculture, as well as the inheritance and innovation of traditional technologies." Yang Wenyu led the team to establish a relatively complete theory and technology of soybean corn belt composite planting and develop corresponding machines and tools after 23 years of continuous research and development. Yang Wenyu also served as the leader of the expert guidance group for the national soybean and oil production capacity improvement project of soybean and corn belt planting, vigorously promoting this technology. It is reported that soybean is a nitrogen fixing crop, while corn is a high nitrogen consuming crop. Soybean is relatively shade tolerant, and corn is just shading. This technology can not only reduce the consumption of fertilizer, but also effectively improve the soil environment, reduce pests and diseases, and achieve complementary advantages by planting tall corn and shade tolerant soybean. "My team and I have realized the mechanization of the whole process of soybean corn strip composite planting through tackling key problems and positioning tests, with the organic matter in the soil increased by 18% and the pesticide application reduced by 25%." Yang Wenyu said that through these changes, the traditional "sweat agriculture" has gradually transformed into a modern and sustainable "green agriculture" and "smart agriculture", which has improved the quality, cost saving, efficiency and security of agricultural production and ensured food security in the long run. "This technology has not reduced the yield of corn, increased the yield of soybeans by 100~150 kg per mu, and produced 1.5 mu of grain per mu of land, giving the villagers a taste of the benefits of science and technology." Yang Wenyu said. Not long ago, the Ministry of Agriculture and Rural Affairs organized the yield measurement and acceptance. In the 200 mu demonstration field of soybean corn composite planting, the corn yield per mu was 633 kg, and the soybean yield per mu was 165 kg. In the past ten years, Sichuan has vigorously promoted this technology, and last year, the soybean yield jumped from the 12th in China to the 3rd. This year, the No. 1 central document of the Central Committee of the Communist Party of China (CPC) clearly requires the promotion of belt planting of soybean and corn in the Huang Huai Hai, Northwest and Southwest regions. According to the data, more than 15 million mu of land has been promoted nationwide this year, basically realizing the expected goal of "no reduction in corn production and one more season of beans". The state has taken new measures to stabilize corn and expand soybean production. "Science and technology are the primary productive forces. The report of the 20th National Congress of the Communist Party of China attaches great importance to scientific and technological innovation. From a new starting point,
