Li is the founder of the self-line hybridization of corn based on heterosis theory. He developed “Zhongdan No.2”, a corn hybrid resistant to multiple stresses. This high-yield hybrid has been widely grown in China since 1982, with a total planting area of between 1.5 to 2 million hectares per year, and has become the most widely cultivated corn hybrid in China. He won a first class prize of the National Invention Award. He opened up the studies on the quality breeding, population improvement and genetic male sterility and has made significant progress. He was in charge of the corn breeding programs of the State key scientific and technological tasks during the Sixth and Seventh Five-Year Plan periods and made great achievements. He has made important contributions to the corn breeding and production in China.

He was elected Member of the Chinese Academy of Sciences in 1980.
