摘　　要：中国南方双季稻秸秆资源丰富,为提高秸秆综合利用率,研究不同秸秆还田量对水稻产量及土壤理化性质有重要意义。试验于2017—2019年在湖南娄底进行,设置五个组别,分别为对照组CK,1/4还田组,半还田组,3/4还田组,全还田组。分析在不同秸秆还田量处理下水稻产量,土壤有机质,全氮含量的差异。秸秆还田组别与CK相比,3年的水稻产量总体呈增长趋势,土壤有机质及全氮含量也有一定的提高,因此采用秸秆还田可促进农民增收,改善耕地质量,从而实现农业的可持续发展。South China is rich in double-cropping rice straw resources.In order to improve the comprehensive utilization of straw,it is of great significance to study the amount of different straws returned to the field on rice yield and soil physical and chemical properties.The experiment was conducted in Loudi,Hunan from 2017 to 2019.Five groups were set up,namely the control group CK,the 1/4 return to a field group,the half return to a field group,the 3/4 return to a field group,and the full return to a field group.Analyze the differences in rice yield,soil organic matter,and total nitrogen content under different treatments of straw returning to the field.Compared with CK,the rice output of the straw returning group showed an overall increase in three years,and the soil organic matter and total nitrogen content also increased to a certain extent.Therefore,the straw returning to the field promotes farmers'income and improves the quality of arable land,thereby achieving sustainable agriculture development.
