摘要
地膜覆盖种植可持续发展的关键是残膜污染的治理,而生物降解地膜是从根本上解决残膜污染的良策。按主要成分来源将生物降解地膜分为3类:天然高分子型、化学合成型和微生物合成型,还介绍了生物降解地膜的成型工艺及其在农业生产中的应用,以期为生物降解地膜技术的发展和推广应用提供指导。
The key factor affecting the sustainable development of plastic film mulching planting is the treatment of residual film pollution,while the biodegradable mulching film can be a fundamental solution to the residual film pollution.In this paper,the biodegradable mulching films were classified into three types according to the sources of their main components:natural polymer based,chemically synthesized polymer based and microbial-derived polymer based.This paper also introduces the molding technology of biodegradable mulching films and its application in agricultural production,in order to provide guidance for the development and application of biodegradable mulching film technology.
