摘要
塑料地膜覆盖技术在给农业带来显著经济效益的同时,也对土壤和环境造成了严重污染,采用光降解薄膜是减轻这些污染的有效途径。本文叙述了塑料薄膜对生长作物的作用以及残留薄膜对环境和农业耕作的危害,同时,也对光降解机理、光降解薄膜的生产和应用做了简要介绍。
Plastic mulching films have caused serious pollution to soil and environmentwhile bringing about obvious economic benefits to agriculture. Using the photodegradablefilms is an effective way to lighten the pollution. The effect of plastic films on growingcorps, the harm of residual films to environments and farming operations are described. Atthe same time, the mechanism of photodegradation, the production and application of thephotodegradable films are simply introduced.
