| 摘 要： | 渗水地膜覆盖具有显著的渗水、保水和提墒作用,提高了旱地高粱自然降水利用率;在高粱生长前期,渗水地膜覆盖的增温、保温效果优于普通地膜覆盖,在生长中、后期地温略低于露地,具一定的缓温效应.

| 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. |
