MA Jian，Male, born in Auguest 1982, native of Shenyang, Liaoning Province. Master's degree supervisor. Researcher. His main research interests include in the prevention and control of agricultural non-point source pollution, and conducting research in the field of efficient treatment and high-value utilization of agricultural waste. Breakthroughs have been made in key technologies such as composting, anaerobic fermentation, and hydrothermal treatment, creating new technologies and products, and formulating efficient restoration strategies for degraded soil mainly in facility agriculture. Has undertaken key research and development projects of the Ministry of Science and Technology, leading special projects of the Academy, and key research and development tasks of provincial and municipal levels. Expert in green and low-carbon development at the General Station of Animal Husbandry of the Ministry of Agriculture.
