天然纤维素基降解塑料地膜的现状与发展趋势

普通塑料地膜给我国农业生产带来了一系列社会和环保问题。为防止"白色革命"演变成为"白色灾害",提出了采用价廉、质广和量多的废弃天然纤维素资源为原料,大力开发一种环境友好型、使用性能优良、成本低廉和透光性能优异的纤维素基,可完全降解地膜,是今后我国地膜覆盖栽培技术可持续发展的关键所在。为此,进一步阐述了天然纤维素基可降解塑料地膜的现实意义和国内外发展现状及存在的主要问题;并对其今后的发展趋势进行了展望。

Status and Development of Natural Cellulose Based Degradable Plastics Mulching Film

A series of Contemporary Society and environmental protection problem in agricultural industry were caused by normal plastics mulching film.To prevent "white revolution" changing into "white disaster",natural cellulose based full degradable plastics mulching film which is eco-friendly,fine service performance,low costs and good light transmission was prepared from natural high molecular cellulose resources.Cellulose material is abundant,good reactivity,excellent biodegradable property and non-toxicity will play more important role on soverlay and cultivation techniques of mulching film.Its research and application are the ideal way to resolve the"white pollution"problem in the present world and promises a wide market foreground.The practical significance,current researching status and development out and in the country,present problems of this kind of degradable mulching film are pointed out in this paper.The future development tendency is also discussed.
