天然生物可降解性材料在农业领域中的应用

The Application of Natural Biodegradable Materials in Agricultural Field

为了研究天然生物可降解性材料在农业领域中的应用,综述了国内外近20年源于农业领域的几种天然生物可降解性材料,如淀粉、聚乳酸、纤维素、木质素、丝素、胶原、壳聚糖和甲壳素等的研究现状,发现天然可生物降解性材料在农业领域土壤改良与水土保持、病虫害防治、保鲜与防腐、食品与饲料添加剂、生物肥料等方面应用广泛,但关于天然生物可降解性材料的特性、材料的优化设计与改良研究等方面还存在不足,今后还需研究如何改良天然生物可降解性材料特性以及拓宽其在农业领域的应用范围。

In order to study the application of natural biod reviewed the literatures at home and aboard in last 20 egradable materials in agricuhural field, the author years about some kinds of natural biodegradable materials including amylum, polylactide, cellulose, lignin, silk fibroin, collagen, chitosan and chitin which were derived from agricultural field. It was found that： the natural biodegradable materials had been applied widely in agricultural field, such as soil improvement, soil and water conservation, diseases and pest control, food fresh and anticorrosive, food and feed additives, bio-fertilizers and so on. However, there were insufficient researches on characteristic of natural biodegradable materials and their optimal design and improvement. In the future, it is needed to improve the characteristic of natural biodegradable materials and broaden the range of their application in agricultural field.
