摘　　要：试验研究了玉米田覆盖渗水地膜后的增温、增湿及增产效应,结果表明:全生育期内渗水地膜较普通地膜平均增温0.41℃,土壤含水量平均增加0.65个百分点,玉米产量增加10.87％,并达到极显著水平。The paper studied the effects of increasing soil temperature, soil moisture content and maize yield by the way of covering water-osmosis plastic membrane. The results showed that by using water-osmosis plastic membrane the soil average temperature increased 0. 41℃ and the soil moisture content increased 0. 65 percent during the whole maize growth period, and the yield increased 10. 87 percent, in contrast with covering common plastic membrane.
