Abstract: In order to use the small rainfall resources, water osmosis plastic membrane was exploited.This membrane has many functions that may make rain penetrate into soil, prevent water evaporation from top soil, increase soil temperature, modify the maximum temperature for soil, ventilate soil, and facilitate soil ventilation.The test of maize covered with water permeability plastic membrane in dryland in Xixian county showed that :①There was 38 3% increase in maize yield and 2 percent increase in soil water at soil depth of 0-100cm for the water permeability plastic membrane than that of conventional membrane and 103% more increase in yield than no cover.②There was similar soil temperature between the water permeability membrane and normal membrane.③The rain efficiency reached 23 25kg?mm -1 ? ha for maize in 1997 for the water permeability membrane. Finally, the prospects for increasing yields of different crops in dry and semi arid land through using water permeability membrane were pionted out.
