Zizania-rice rotation system was established and treated by 3 fertilizing methods,and the effects of fertilizer treatments on ecological environment and crop yield of zizania-rice rotation system were investigated. Results showed that the organic fertilizer was beneficial to zizania-rice rotation system system both in ecological environment and soil fertility. Soil in that cropping system had the lowest bulk density (1.15 g/cm3 ) and highest total porosity (54.92％) ,its water storage was 27.36 mm. The organic matter and total nitrogen in 0-10 cm layer of soil was 46.02 and 1.82 g/kg,in 10-20 cm layer was 45.05 and 1.21 g/kg. The system also had the highest zizania yield of 74 800 kg/hm2. There was no significant difference on rice yield among the cropping system treated by different fertilizing methods.%通过田间试验,研究了3种不同施肥处理对茭白-水稻轮作系统中土壤理化性质与产品产量的影响.结果表明,在水稻收获后,有机肥处理的土壤容重达到最低,为1.15 g/cm3; 总孔隙度最大,为54.92%;贮水量最高,为27.36 mm.施用有机肥能提高土壤肥力,有机肥处理的土壤有机质、全氮总体最大,0～10 cm土壤有机质,全氮分别为46.02、1.82 g/kg,10～20 cm土壤有机质、全氮分别为45.05、1.21 g/kg.有机肥处理的茭白总产量最高,为74 800 kg/hm2.而在水稻产量上,各个处理间的差异不显著.
