残膜机械化回收技术

地膜具有保墒、提高地温、抑制杂草生长和增产增收等作用，得到了广泛应用，并极大地促进了我国农业经济的发展。但是残留在土壤中的地膜极难降解，给农业生产和生态环境造成了巨大危害，残膜回收对于保护耕地、改善农田生态环境具有重要的意义。总结了国内外残膜回收技术的研究现状及研究方法，指出我国残膜回收机具存在的主要问题，提出了实施机械化残膜回收技术的建议，为机械化回收残膜的研究提供理论依据。 

Mechanical Recovery Technology of Residual Film

Film has keeping moisture，improving soil temperature，inhibiting weeds growth and increasing production effects，so it has been widely applied.And film has greatly promoted development of China′s agricultural economy.But plastic film residue in soil is extremely difficult to degrade，which cause great harm to agricultural production and ecological environment.Remnant membrane recycling has great significance for protection of farmland and improving farmland ecological environment.Current research status and research methods of remnant membrane recycling technology at home and abroad were summarized.Main problems existing in remnant membrane recycling machines in China were pointed out.Suggestions of implementing residual film recovery technology of mechanization were put forward.It provided a theoretical basis for mechanical recovery of residual film.
