Abstract
The water-permeability plastic film mulching had obvious effect on water-permeability,water retention and raising soil moisture.And its moisture was superior to the common plastic film mulching material and the efficiency of water application for dryland sorghum was improved in whole sorghum growing season.The effect of temperature-increasing and insulation of water-permeability plastic film mulching was superior to the common plastic film mulching material in early period of sorghum growth.The soil temperature was lower than that in opening ground in middle and final period of sorghum growth,which showed the water-permeability plastic film mulching had the effect on lowering soil temperature slowly.
