摘　　要：为揭示可降解膜覆盖的保水增产效应,开展了旱棚微区控水条件下花生不同材料膜覆盖试验。结果表明:液态生物降解膜与聚乙烯膜覆盖后,0-30cm土层苗期贮水量分别较对照增加64%和91%,花针期降低蒸发19%和16%,保水性能较好。粉剂降解膜与纤维黑色纸膜在花针期的水分散失较多,与对照差异不显著。液态生物降解膜、聚乙烯膜与对照相比,生物产量分别提高22.5%和25.3%,经济产量提高40.6%和39.1%,水分利用效率提高45.1%和37.8%,增产效果显著。To reveal the effect of film, a study on different kinds the soil moisture retention and increasing in yield under degradable mulching of material films on peanut was carried out in the watershed microplot. The results indicate that： Covered with liquid biodegradable film and polyethylene film, the water storage capacity on the seedling stage were increased by 64~//00 and 91~//00 in 0--30 cm, the evaporation at the flowering and pegging stage reduced by 19~//00 and 16~/60, and the effect of water retention was better. But covered with powder degradable film and fiber black resin film, more water was lost on the flowering and pegging stage, comparing with the controlled treatment, their differences were not significant; compared with CK, the biological yield of liquid biodegradable film and polyethylene film were increased by 22. 5% and 25. 3%, economic output increased by 40. 6% and 39. 1%, water use efficiency increased by 45. 1% and 37. 8%, and the effect of increasing economic output was significant.
