摘　　要：[目的]为解决塑料地膜覆盖带来的棉田白色污染，寻找塑料地膜的替代产品。[方法]搜集市场上的3种液体地膜，以裸地和塑料地膜覆盖为对照，测定5cm土壤温度和0～20cm土壤含水量、棉花生长发育性状以及棉花产量。[结果]3种液体地膜均表现出了一定的增温与保水效果，使棉花前期与后期生长发育更加平衡，棉花产量与塑料地膜覆盖处理相当。[结论]液体地膜具有一定的推广价值．但使用量与使用方法仍需进一步试验研究。[ Objective ] The research aimed to seek the replacement of plastic film and solve the problem of white pollution. [ Method ] The effects of three liquid films were tested with no mulching and plastic film mulching as control, in which soil temperature at 5 cm depth, soil moisture at the top 20 cm layer, traits of cotton growth and development and yield were investigated. [ Result ] The three liquid films all increased soil temperature and moisture, which made cotton development more balanced in early stage and late stage and achieved equivalent cotton yield. [ Conclusion] Liquid films could be used in cotton cultivation, but the using method and dosage should be studied further.
