The impacts of wind-speed and straw-mulching on soil water evaporation were measured and analyzed with 9 treatments of three wind-speeds(calm wind,0.5 or 1.5 m/s) and three straw-mulching levels(0,4 120,or 8 240 kg/hm2).The results showed that when the water content was 70% of the field moisture capacity and mulching(0,4 120 kg/hm2) was the same,the soil water evaporation with wind-speed 1.5 m/s was significantly higher than other treatments;when the water content was higher than 55% of the field moisture c...
