摘　　要：回顾了液态地膜的使用历程,简述了国内5代液态地膜的生产情况,总结了液态地膜的应用对象、应用范围以及应用效果,充分表明液态地膜可适用于大多数作物,适用地域之广,并可显著提高作物产量、土壤温度、水分含量和水分利用效率,有效减少水土流失和"白色污染",改善农田生态环境,推动了国内绿色农业可持续发展的进程。同时也指出了液态地膜在使用过程中存在的问题,仍需科技工作者对液态地膜的喷施环境、喷施浓度、持久性和完整性等继续研究,不断升级换代,获得更佳效果。最后提出了废弃资源再生液态地膜的发展设想,液态地膜覆盖集成技术的研发趋势。This paper reviews the development history of liquid film,and briefly describes the production materials of each of the five generations of liquid film in China,then summarizes the application objects,scope of application and application effects of liquid film.Many studies have shown that liquid film can be applied to most crops and a wide range of areas.It can significantly increase crop yield,soil temperature,water content and water use efficiency,effectively reduce soil erosion and“white pollution”,improve farmland ecological environment,thus to promote the sustainable development of green agriculture in China.The study points out some problems such as the spraying environment,injection concentration,durability,and integrity of liquid film,existing in the application of liquid film,which need further research by scientific and technological workers to continuously upgrade liquid film to obtain better results.Finally,it puts forward the assumption about waste resource regeneration liquid film,and discusses the research and development trend of integrated technology.
