Abstract:This paper systematically analyses effects of different crops (Zizania latifolia、lotus、chufa)and proportions(1:5、1:10、1:20) to control nitrogen and phosphorus non-point source pollution from hill region paddy field on field experiment. The suitable pattern of ecological control techniques of nitrogen and phosphorus non-point source pollution is presented,namely to construct 1:20 proportion Zizania latifolia wetland system.
