Three different soil textures, soil water and salt movement characteristics under the different water repellencies and open hole ratios of plastic mulch conditions were studied by evaporation experiment on different water repellent soils under perforated plastic mulch. The results showed that cumulative evaporation was proportional to square root of time on different water repellent soils under perforated plastic mulch; evaporation of soil was inhibited by the soil water repellency; cumulative evaporation per unit hole area film（Er） rapidly decreased when the open hole ratios increased, power function of Er and the open hole ratios were established; variation rate of soil evaporation on vertical profile decreased when soil water repellency increased; the more open holes ratio was, the more variation rate of salt on vertical profile would be, and the degree of soil water repellency had weak effect on soil salt.
