Abstract:

Wuhu City is located in the Yangtze River Economic Zone, where the agricultural non-point source pollution control is vitally important to the ecological conservation of the Yangtze River. This study analyzed the amount of chemical fertilizer use in Wuhu City in 2017, calculated the nitrogen and phosphorus loss of farmland, and analyzed the present situation of chemical fertilizer application. It is found that the main problems of traditional chemical fertilizer use in Wuhu City are unreasonable fertilizing method and structure, single fertilizer type with large application rate, and low popularization rate of high-efficiency fertilizing technology. The research put forward the side deep fertilizing technology of mechanized rice transplantation, the accurate quantitative cultivation technology of rice, the light and simple cultivation technology of rape, the interception technology of ecological ditches and the utilization technology of farmland tail water, aiming to establish the technical system of fertilizer reduction and efficiency improvement. The results can provide technical reference for improving the ecological environment of the Yangtze River Basin and promoting the green development of agriculture in Wuhu City.

Key words: chemical fertilizer, fertilizer reduction and efficiency improvement, crop farming, non-point source pollution, nitrogen and phosphorus loss, fertilization mode, the Yangtze River basin, Wuhu City
