| 摘 要： | 采用地膜创新产品———渗水地膜,以普通地膜及露地为对照,对渗水地膜覆盖下麦田的土壤温度、产量及水分生产率进行了初步探讨。结果表明:渗水地膜在整个生育期内的保温、增温效果优于普通地膜,同时还可以降低午后极端高温,使土壤温度较为稳定;渗水地膜覆盖与普通地膜覆盖产量差异达0.01极显著水平,较普通地膜覆盖增产505.30 kg.hm-2,产量提高了13.20%;渗水地膜的水分生产率最高,露地最低。渗水地膜水分生产率比露地提高25.1%,比普通地膜提高8.6%。

| Abstract: | 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. |
