Abstract To reveal the effect of restraining soil water evaporation with different mulching models, through simulation test, the effect of restraining soil water evaporation was analyzed. Five modes were set up including bare land(CK), sand mulching(S), sand and plastic film mulching(SM), straw and plastic film mulching(JM)and straw and sand mulching(JS). The result showed that the soil daily evaporation capacity is different with the different mulching modes of soil surface. In the early evaporation, the soil moisture evaporation capacity is CK>JS>JM>S>SM, then the change trend becomes CK>JS>S>SM>JM. When rainfall occurs, the change of soil moisture evaporation capacity is from CK>JM>SM>JS>S to CK>JS>S>SM>JM. The different mulching models can effectively reduce soil water evaporation. Soil water cumulative evaporation capacity of bare land, straw and sand mulching, straw and plastic film mulching, sand mulching, sand and plastic film mulching is respectively 1 823.6g, 712.2g, 473.3g, 450.6g, 375.1g, soil water cumulative evaporation capacity of straw and sand mulching, straw and plastic film mulching, sand mulching, sand and plastic film mul-ching decreases by 60.9%, 74%, 75.3%, 79.4% respectively, compared with CK. In the whole evaporation process, the relationship between soil water cumulative evaporation capacity and time under different mulching models is W=atb. By comprehensive analysis, sand mulching is a more reasonable mulching model in the test area.
