摘　　要：试验研究了花生田使用渗水地膜后的保水、增温效应,以及它的增产效果。结果表明,全生育期内渗水地膜较普通地膜平均增温0．325℃；土壤含水量平均增高1．26个百分点；产量平均增加幅度为9．9%。The paper studied the effects on increasing soil temperature, soil moisture content and peanut yield by the way of covering water-osmosis plastic membrane. The results showed that by using water-osmosis plastic membrane the average soil temperature increased by 0. 325℃ and the soil moisture content increased by 1.26 percent during the whole peanut growth period, and the yield increased 9. 9 percent, in contrast with covering common plastic membrane.
