Since 1987, he has participated in or presided over 9 projects, such as Grain Storage and Fresh-keeping Technology (Rice Natural Low-temperature Auxiliary Ventilation and Fresh-keeping Technology), CTCD Series Multi-functional Ventilation and Fumigation Device for Granary, CTHC Series Phosphine External Circulation Fumigation Device, Arch Board Warehouse Sealing Engineering Technical Transformation and Grain Storage Application Research, and ALP Low-dose Dynamic deliquescence Under-film Circulation Fumigation Technology Research. 1999 puts forward the "dynamic deliquescence" method of circulating fumigation of aluminum phosphide, which has been adopted by more than two-thirds of warehouses in China. Participated in or presided over dozens of projects from 1992, including the technical transformation of old granaries, the design of dryers and the design of ventilation and fumigation systems; 1993 developed a multifunctional ventilation fumigation decompression device for granaries, which solved the problem of grain storage in barrels. 1993 ~ 1996 participated in the project of "improving China's grain circulation with World Bank loans" and established China Grain Logistics Research and Training Center; Participated in the construction of national new warehouses, and participated as the chief designer in the design of 1998 "National 50 billion Jin Grain Warehouse Construction Standard Drawing" (storage technology part), as well as the subsequent air tightness transformation of new warehouses.
