【目的】通过模式对比,探究“紫云英还田+稻鱼共生”对水稻土壤养分和产量的影响规律,为水稻的高效优质生产及可持续发展提供科学依据。【方法】设置紫云英还田(ZD)、稻鱼共生(YD)、紫云英还田+稻鱼共生(ZY),以常规水稻种植(CK)为对照,共4个处理,进行各处理土壤pH、土壤养分(有机质、全量氮磷钾及其有效态)含量、水稻产量和产量构成指数的测定、分析和比较。【结果】与CK处理相比,YD、ZD和ZY处理均能有效提高当季水稻土壤肥力,其中ZY处理效果最优。ZY处理成熟期土壤有机质、土壤全量氮、磷、钾及其有效态含量较CK处理分别提高16.40 %、18.18 %、20.63 %、3.42 %、7.71 %、15.96 %和1.85 %(P

【Objective】Through the comparison of models,the present paper aimed to explore the influence of‘chninese milk vent Returning to the Field coupled with rice and fish symbiosis'on the soil nutrients and yield of rice,and provided a scientific basis for efficient and highquality rice production and sustainable development.【Method】In this experiment,four treatments including conventional rice planting as a control(CK),chninese milk vent Returning to the Field(ZD),rice and fish symbiosis(YD), chninese milk vent Returning to the Field coupled wi...
