Abstract
The experiment design was Latin square about three treatments included water-permeability plastic film mulching,common plastic film mulching and open ground.The experiment studied variable rule of Annual moisture.The result showed that:The water-permeability plastic film mulching had effect of preservation and increase soil moisture,and its moisture was superior to common plastic film mulching 抯 in the whole growing season.The soil moisture of water-permeability plastic film mulching in 0~80 cm soil layer is higher than open 抯 in much phase,but in 80~140 cm soil layer its is lower than open's.
