摘　　要：以壳聚糖、聚乙烯醇、淀粉为原料,通过交联反应制备了可生物降解的壳聚糖肥料包膜材料,详细讨论了制备过程中的诸因素对膜性能的影响。结果表明,制备的薄膜的性能优于纯壳聚糖膜,可以用作缓释肥料包膜。The biodegradable coating materials of fertilizers were made of chitosan, polyvinyl alcohol(PVA) and starch by crossing-linking reaction in this paper. The influencing factors were investigated on the film properties during preparation. The results show that the prepared film is better than the chitosan film and can be used as coating film of slow-release fertilizers.
