摘要
地膜可有效保温保墒、抑草防病防虫,地膜覆盖栽培能实现作物增产增收及耕地的高值利用,但普通聚乙烯(PE)地膜难降解、难回收,容易造成"白色污染",危害土壤生态环境.生物降解地膜已成为可持续发展高效农业中普通PE地膜的替代品,其生产与应用的增长趋势显著.本文简述了降解塑料的定义、分类及发展历史,介绍了降解地膜研发应用现状,综述了我国生物降解地膜的研究与应用情况,并结合生物降解地膜的应用优势,分析了推广应用的理论依据,提出了相关建议.
Abstract
Plastic mulching effectively retains heat and moisture,suppresses weed growth,prevents diseases and insect pests,and when used in crop cultivation,it increases crop yields,income,and high-value utilization of cultivated land.However,due to the inadequate degradability of polyethylene(PE)film,it tends to cause"white pollution"and harms the soil ecological environment.Degradable mulching film has become a substitute for PE mulching film in sustainable agriculture.The production and application of degradable mulching film is gradually increasing.This article briefly describes the definition,classification,and development history of degradable plastics,introduces the current status of research and application of degradable plastic film,and summarizes the research and application of biodegradable plastic film in China.Finally,combined with the advantages of biodegradable plastic film application,the article analyzes the theoretical basis for promoting the application of biodegradable plastic film and puts forward relevant suggestions for its research and development.
