摘　　要：壳聚糖作为一种在自然界储量丰富的天然高分子成膜材料,具有抗菌、促进作物生长、保温保湿、可降解等功能性质,符合环境友好的可降解地膜的性能要求。文章概述了壳聚糖的基本结构、主要理化性质,从促进作物生长、缓解土壤板结、诱导植物抗性等角度阐述了壳聚糖在地膜中的主要作用机理,讨论了常见的壳聚糖基地膜及需要改进的方向,并分析了壳聚糖作为可降解地膜材料所存在的问题及发展趋势。Chitosan,a naturally abundant biopolymer,emerges as a promising candidate for eco-friendly degradable mulch films due to its antibacterial properties,crop growth promotion,thermal and moisture retention,and biodegradability.This article outlines the basic structure,and key physicochemical properties of chitosan.It delves into the mechanisms through which chitosan enhances crop growth,alleviates soil compaction,and induces plant resistance in the context of mulch films.The discussion extends to prevalent chitosan-based mulch films and areas for improvement,analyzing the challenges and future trends of chitosan as a degradable mulch film material.
