In the long-term scientific research process, Denghai Seed Industry has made outstanding achievements, taking the lead in realizing five breakthroughs in replacing flat corn with compact corn in China, and leading the breeding direction of replacing flat corn with compact corn. Combining maize breeding with high-yield cultivation for the first time, it pioneered the compact maize breeding, and pioneered the road of high-yield cultivation of maize with improved varieties and good methods. In order to make full use of the light and heat resources in Huanghuai sea area, high-yield cultivation of wheat and corn in two seasons a year was carried out, and the yield per mu in two seasons exceeded16.5 tons, realizing the transformation from feeding one person to feeding four people in one mu. Ye Dannuo. 12 and Ye Dannuo. It broke through 13 of grain yield per mu of summer corn for the first time, and was determined by the Ministry of Agriculture as the main variety of the project of "promoting compact corn 1 100 million mu and increasing grain yield 1 100 million kg during the Eighth Five-Year Plan period". Denghai Seed Industry has won 25 national and provincial awards, including the first prize of National Science and Technology Progress Award, the first prize of National Spark Award and the first prize of Shandong Science and Technology Progress Award. Researcher Li Denghai won the highest prize of Shandong Science and Technology in 2006. Since the Ninth Five-Year Plan, it has undertaken 4 1 projects at the national, provincial and ministerial levels, including 863 Plan, National Science and Technology Support Plan and other national projects 16 projects, reaching the level of national scientific research units. In 2007, the company's newly developed "super corn" was listed as a key project of the "Eleventh Five-Year" national science and technology support plan by the Ministry of Science and Technology.
