摘  要: Straw mulching, one of the core technologies of conservation tillage, can reduce the environmental pollution and field evaporation effectively and increase crop yield. However, there are different effects on the soil conditions in different amount of straw mulch. This paper tested on the different mulching treatment effect on soil quality, and sampled during the winter wheat’s sowing to overwinter time. Then analyzed the soil quality changes under different treatments during this period and did the fuzzy comprehensive evaluation. It can be concluded that it is more reasonable to choose the scheme of 50% straw coverage during the winter wheat’s sowing to overwinter time.
