Who is the breeding expert who has set China’s summer corn yield record seven times?

This is Li Denghai.

As a farmer inventor, Li Denghai is known as the "Father of China's Compact Hybrid Corn", which makes him as famous as Yuan Longping, the "Father of Hybrid Rice", and enjoys the reputation of "Southern Yuan and Northern Li". .

Over the past 30 years, more than 80 new high-yield corn varieties have been bred, and China's summer corn yield records have been set and refreshed seven times. The "Yedan" series of new corn varieties he presided over the breeding process won the first prize of the National Science and Technology Progress Award.

Li Denghai increased the country’s income by 100 billion?

After Li Denghai developed “Yedan No. 2” with a yield of 776.9 kilograms of summer corn, he did not stand still but started his own new business. A round of experimentation and exploration. ?

Since the winter of 1997, Li Denghai has traveled to Hainan, thousands of miles away from Shandong, to conduct corn breeding experiments. Because the climate and temperature in Hainan are relatively suitable for the growth of corn, it can be grown three times a year. In the mature stage, Li Denghai can complete the experiment in one year in Hainan, which took three years in Shandong. ?

Li Denghai once said that the success rate of corn breeding is only one in 120,000, so he has to race against time to conduct corn breeding experiments in order to continue to delve into new results. ?

Hainan’s three-crop-a-year climate and temperature have provided Li Denghai’s corn breeders with unprecedented help. Hard work paid off. In the mid-to-late 1990s, Li Denghai successfully bred the "Denghai" series of new corn varieties, which became the main corn variety in China. ?

Among them, the new corn variety Denghai No. 9 has outstanding characteristics such as excellent quality, high yield, insect resistance, and drought resistance, setting a new record for hybrid corn yield per mu.

After Denghai No. 9 was developed, it was found through national approval that it was suitable for planting in the Northeast, Huanghuai, Northwest and South regions. From 2003 to 2017, Denghai No. 9 was produced and sold cumulatively. 56.2408 million kilograms, the cumulative custody area is 18.7469 million acres, and the cumulative increase in grain production is 11.401 kilograms. ?

The research and development of "Denghai No. 9" has greatly increased the yield of corn and made a huge contribution to China's food security. Because Denghai No. 9 has the characteristics of high starch content, it is suitable for manufacturing new corn. Energy ethanol gasoline has therefore also been favored by ethanol gasoline companies, providing very strong support for ensuring the adequacy and security of China's energy production. ?

Li Denghai then successfully introduced many new corn varieties. After 121 generations of breeding, he finally bred a high-yield corn hybrid variety with a yield of 1,500 kilograms per mu, which has increased social benefits for the country. More than 120 billion yuan.
