摘　　要：微孔膜是近年来发展的农用塑料膜新品种 ,具有增温、保墒、透气、渗水多种功能。加工方法有机械法、放射法、拉伸法、热压法和辅助剂添加法等。微孔膜可作地膜、棚膜、悬浮膜或多重覆盖 ,用于蔬菜、瓜果、烟草等高效益经济作物及粮食作物生产 ,提高产量和改善品质 ,已在很多国家应用 ,取得较好的效果。Porous film is a new variety of plastics in agriculture.It has founctions of temperture increasing, moisture keeping and air/moisture permeability.Porous film is processed either by heat sealing or partly sticking or by physical boring means. Porous film could be used as mulch film, sheet material, rowcover floating film in production of vegetables, orchards, cash or cereal crops and has showed significant effect on yield and quality improvement in many parts of the world.
