摘　　要：以种植花生的红壤旱坡地为对象,研究液态地膜覆盖(LFM)、塑料地膜覆盖(PFM)、稻草覆盖(SM)和无覆盖(NM)对土壤环境和花生生长效应的影响。结果表明:有覆盖物可以显著增加土壤含水量,调节土壤温度,加快花生光合作用,使花生干物质的分配更合理,且提高花生产量;不同覆盖物对土壤和花生生长等各项指标的综合效应不同,表现为稻草覆盖>塑料地膜>液态地膜>无覆盖。The effects of liquid film mulching （LFM）, plastic film mulching （PFM）, rice straw mulching （RSM） and no mulching （NM） on soil physical and chemical properties were studied by using the red soil sloping field of peanut. The results showed that different mulch compared with the no mulch treatment could significantly increase the soil moisture, soil temperature regulation, speed up the photosynthesis of peanut, peanut dry matter distribution more reasonable and increased the yield of peanut. The comprehensive evaluation of different mulches was in the order RSM, LFM, PFM and NM.
