Study on Temperature and Yield Effect of Water-Permeability Plastic Film Mulching in Rainfed Wheat Field

In this experiment,three treatments were used,such as water-permeability plastic membrane mulching,common plastic film mulching and open ground yield.Two effects of the three treatments were studyed.The results show:the effect of temperature-increasing and insulation of water-permeability plastic film mulching was superior to common plastic film mulching and it can make soil temperature comparatively steady.The yield of the water-permeability plastic film mulching was higher 505.3 kg·hm~(-2) than the yield using common plastic film mulching and increased by 13.2%,their variance reaching 0.01 significant level.In the same condition,water utilizatiin of water-permeability plastic film mulching was higher than that of the other two treatments,increased by 25.1% than open ground and by 8.6% than common plastic film mulchuing.
