Born in June 1933, Haiyan, Zhejiang, researcher and doctoral supervisor. /kloc-0 studied in the Department of Agriculture of Fudan University in August, 1950;/kloc-0 studied in the Department of Plant Protection of Shenyang Agricultural College from August, 1952 to August, 1954;/kloc-0 worked as a technician in the beet research institute of China Academy of Agricultural Sciences from August, 1954 to February, 1960. In 1960s, the research on pesticide residues in tea was started, and the degradation laws and prediction models of various pesticides on tea trees were put forward, including 18 national standard and five ministerial standards. It is proved for the first time that air drift is the cause of persistent pesticide residues in tea, and the research is at the forefront of the world. Its laboratory is recognized by the European Union as the only accredited tea export inspection institution in China. In recent years, it has made outstanding contributions to reducing pesticide residues in tea in China, and the national over-standard rate has dropped from 80% to 20% in three years. In the 1990s, a new field of insect chemical ecology was opened up. Based on the chemical communication mechanism of tea tree, pests and natural enemies, it is innovative to clarify the chemical ecological mechanism of pest and natural enemies positioning. The paper was published in important journals such as j.chem. Ecol。 And J. Agger Ricol. Food. Chemistry. Training a group of doctoral students and management talents will promote the tea industry in China.
