Starting as a lecturer, he later became a professor and director of the university's Rice Research Institute.
Li created the Dian (or Yunnan)-type hybrid rice, and was a pioneer in the research of high-altitude hybrid rice. His research resulted in substantial increases in rice yields in the plateau province of Yunnan, raising farmer incomes. Consequently, he was awarded the State Natural Science Award in 1978 and the Fifth Yuan Longping Prize in Agricultural Sciences. He was also named a model worker of Yunnan in 1983. His research is published in the book "Dian-type Hybrid Rice" (滇型杂交水稻).

He joined the China Zhi Gong Party in May 1991, and served as a member of the 10th and 11th Central Committees of the party. He was a member of the 6th National People's Congress, and a member of the 8th, 9th, and 10th Chinese People's Political Consultative Conference (CPPCC). He served on the Standing Committee of the 9th CPPCC.
Li retired in June 2009. He died on 4 April 2018 in Kunming, at the age of 82. Yuan Longping wrote a eulogy praising his contributions to rice research.
