Chitosan and Its Application in Degradable Mulch Film
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.
