n order to explore the impact of mineralization degrees on infiltration character of soil under moistubeirrigation, an indoor soil box simulation experiment method was used to investigate the infiltration character of soil water under five different mineralization degrees selectively. Results indicated that the degree of mineralization had small impact on the shapes of soil wetted zone, and the wetting front shape were similar to circle. Degree of mineralization had a relatively bigger influence on the volume of wetted soil.The volume of wetted soil in mineralized water was bigger than that in pure water. When the degree of mineralization was 3g/L, the wetting front (horizontal, vertical up and down) migration distance was the farthest, which had a power function relationship with time. The mineralized water could increase cumulative infiltration.However the relationship between cumulative infiltration and degree of mineralization was not linear relationship.The cumulative infiltration and average soil moisture content was the biggest when the degree of mineralization was 3g/L.The results of this study provided reference for the utilization of moistubeirrigation with mineralized water.
