海河平原冬闲期种植绿肥对作物产量和土壤情况的影响

Objective ] To clarify the effects of planting green manure in winter fallow period on crop yield and soil conditions, and to explore the influencing factors of planting green manure on the yield effect of food crops, so as to provide theoretical basis for the scientific application and promotion of green manure planting in China. [ Method ] With conventional fallow as the control, different treatments were set up by fallow and planting green manure, and the crop yield and soil conditions were analyzed and studied for two consecutive years. [ Result ] During the whole experiment period, planting green manure every two years had the most obvious effect on wheat yield and soil condition, and wheat yield increased by 4.37 % compared with fallow. [ Conclusion ] From a comprehensive point of view, planting green manure has the potential to promote sustainable agricultural development and green agriculture to a certain extent, which can ensure food security and maintain water resources security of ecological environment to a certain extent.
