Chapter 58 57. Li Denghai——Dedicating himself to agriculture and winning high yields

Li Denghai, male, Han nationality, native of Laizhou City, Shandong Province, member of the Communist Party of China. Born in 1949, he is currently the chairman of Shandong Denghai Seed Industry Co., Ltd. and the director of the National Corn Engineering Technology Research Center (Shandong). In the history of corn cultivation in the world today, there are only two people recorded in the archives. One is Wallace, the founder of the American Pioneer Seed Company, who holds the world high-yield record for spring corn; the other is Li Denghai of China, who holds the world high-yield record for summer corn. Creator. Over the past 30 years, more than 100 excellent corn hybrids he has bred have added 100 billion kilograms of grain to New China, making outstanding contributions to the realization of my country's transition from a "big grain country" to a "grain power".

Since Li Denghai engaged in agricultural scientific research, he has devoted himself to the research of corn breeding and high-yield cultivation for a long time. He has spent more than 30 consecutive Spring Festivals in the breeding base in Hainan, carrying out scientific research and breeding at the rate of 3 to 4 generations per year, creating a precedent for compact corn breeding in my country. .The corn varieties he researched broke the high-yield record of my country's summer corn seven times, and he is known as the "father of compact hybrid corn". In 2005, the world's highest summer maize production record of 1402.86 kg per mu was created and has been maintained till now.52 compact corn hybrid varieties have been bred successively, and 52 have passed the examination and approval of the state and relevant provinces and cities, and 44 new plant variety rights and 10 patents have been obtained.Since the country implemented the "Ninth Five-Year Plan", he has undertaken 41 national, provincial and ministerial projects, among which the project "Breeding and Promotion of High-yielding Corn Yedan 13" won the first prize of National Science and Technology Progress Award.In order to speed up the transformation of scientific research results, he set up breeding centers and test stations in various corn production areas across the country, building the largest scientific research platform for corn breeding in China.At present, the high-yield corn varieties cultivated by him have been promoted in an area of ​​1 billion mu across the country, realizing economic benefits of more than 100 billion yuan, making important contributions to ensuring national food security.He is a representative of the 14th and 17th National Congress of the Communist Party of China, and a representative of the 8th to 11th National People's Congress. youth".

As a farmer inventor, Li Denghai is known as "the father of compact hybrid corn in China".This laurel crown can best demonstrate his true qualities, making him as famous as Yuan Longping, the "father of hybrid rice", and sharing the reputation of "South Yuan and North Li". In the mid-to-late 1990s, he bred the "Denghai" series of new corn varieties, which became the main variety in my country across the century.The new corn variety Denghai No. 9 has the outstanding characteristics of high quality, high yield and multi-resistance. Its yield is 11.4% higher than that of "Yedan No. 13", which won the first prize of the National Science and Technology Progress Award.Approved by the state, it is suitable for planting in the northeast, Huanghuaihai, northwest and southern corn regions. From March 2000 to the end of 2007, the cumulative production and sales of Denghai No. 9 was 56.2408 million kilograms, the cumulative promotion area was 18.7469 million mu, the cumulative increase in grain production was 1.14 billion kilograms, and the cumulative increase in social benefits was 1.14 billion yuan, making contributions to ensuring my country's food security.Denghai No. 9 has high starch content and is also favored by ethanol gasoline production enterprises, which also provides a strong variety support for ensuring my country's energy security.

In 2005, he founded Shandong Denghai Seed Industry Co., Ltd., which was successfully listed on the Shenzhen Stock Exchange's small and medium-sized board. Its earnings per share and net assets per share both ranked among the top ten of 1,370 listed companies in 2004 and the first half of 2005. As the first completer, he has obtained 29 new plant variety rights; since 2002, he has obtained 6 national invention patents; since 2005, he has won the first prize of scientific and technological progress in Yantai City and Shandong Province; in 2008, he was awarded the Ministry of Agriculture respectively The 2nd China Talent Award and the 10th China Patent Excellence Award.

Beginning in 1988, 26 self-fertilizing compact and superior maize inbred lines were distributed free of charge to national breeding institutions, which promoted the development of maize breeding in my country. In 1996, the Li Denghai Youth Science and Technology Fund was established, with a bonus of 100,000 yuan. In 2000, it sponsored the "Denghai Cup" Laizhou Top Ten Outstanding Youth selection activity, which has been carried out for 8 sessions so far. In 2007, donated 200,000 yuan in cash to Laizhou Charity Federation for social welfare undertakings. In 2008, to support post-disaster reconstruction in Sichuan, donated 1.3 million yuan in cash and 1.8 million yuan worth of improved corn seeds.
