Shandong Denghai Seed Co., Ltd. is an innovative agricultural high-tech listed company with 25 wholly-owned and controlled subsidiaries and 6 branches. From 1972 to the present, Li Denghai has led a scientific research and innovation team and has conducted research on high-yield and key fields for more than 800 pieces of corn for more than 40 years, and established in my country that compact hybrid corn is the development direction of high-yield corn in my country.

From 1972 to the present, 146 generations of high-product breeding have been carried out, insisting on independent innovation and original innovation, and summarizing that compact corn hybrids have "five major breakthroughs" than flat corn hybrids, and a yield of more than 700 per mu has been developed , 800, 900, 1000, 1100 to 1400 kg of summer corn compact high-product products, and spring corn compact high-product products with a yield of more than 1500 kg per mu. In 2013, 100 mu of wheat (600 kg per mu ) and corn (1151.65 kg per mu ) produced a high yield of 1,750 kg per mu, exceeding the national average yield. At present, the cumulative planting area of ​​high-quality corn breeds selected by Li Denghai led the scientific research and innovation team to breed more than 1.3 billion mu, creating more than 130 billion yuan of social and economic benefits, and in promoting the technological progress of hybrid corn in my country, agricultural yields, farmers' income growth, and ensuring national food security. Great achievements have been made.

In 1985, Li Denghai established a private industrialization test station integrating scientific research, promotion and sales, which started a new journey of industrialization development of Denghai seed industry. During the national "Eighth Five-Year Plan" and "Ninth Five-Year Plan" period, the compact hybrid corn produced by Li Denghai nationwide accounted for more than 1/3 of the national planting area, accounting for 90% of the corn planting area in Shandong Province. At present, the company has established an innovation system with enterprises as the main body, market-oriented, and combining production, education and research, and its independent innovation capabilities have been improved. The company has invested more than 800 million yuan in the northwest provinces and regions of China, established a stable corn seed production and processing base, and installed a modern large-scale seed processing production line integrating fruit ear drying, threshing, selection, coating and packaging to Continuously provide high-quality seeds to the market. In my country, we actively promote the sowing of corn precision single grains, which has played a guiding and promoting role in reducing the seedlings per mu, saving farmers' labor for seedlings, and ensuring the reasonable density per mu; we have established the concept of serving seed users in all aspects and improved the marketing network system; , the market share of high-yield corn seeds has increased year by year. On the basis of expanding the industrialization of corn seeds, the company continues to expand the development of special corn, wheat, vegetables, flowers and other industries, and the level of diversified and large-scale industries is further improved.

Denghai Seed Industry will continue to hold high the banner of "creating the high-yield path of China's corn and catching up with the advanced level of the world", climbing the peak of the record of high-yield hybrid corn, and guiding the selection and breeding of high-yield hybrid corn products in my country; using scientific research and innovation as the driving force for the construction of species New contributions to strengthening the country, ensuring national food security, and realizing the great rejuvenation of the Chinese nation.
