Chitosan is a naturally occurring compound that can be obtained from deacetylated chitin, which is obtained from various sources such as fungi, crustaceans, and insects. Commercially, chitosan is produced from crustaceans. Based on the range of its molecular weight, chitosan can be classified into three different types, namely, high molecular weight chitosan (HMWC, >700 kDa), medium molecular weight chitosan (MMWC, 150-700 kDa), and low molecular weight chitosan (LMWC, less than 150 kDa). Chitosan shows several properties that can be applied in horticultural crops, such as plant root growth enhancer, antimicrobial, antifungal, and antiviral activities. Nevertheless, these properties depend on its molecular weight (MW) and acetylation degree (DD). Therefore, this article seeks to extensively review the properties of chitosan applied in the agricultural sector, classifying them in relation to chitosan's MW, and its use as a material for sustainable agriculture.
壳聚糖是一种天然存在的化合物，可从脱乙酰几丁质中获得，而脱乙酰几丁质可从多种来源获得，如真菌、甲壳类动物和昆虫。在商业上，壳聚糖是由甲壳类动物生产的。根据其分子量范围，壳聚糖可分为三种不同类型，即高分子量壳聚糖（HMWC，>700 kDa）、中分子量壳聚糖（MMWC，150 - 700 kDa）和低分子量壳聚糖（LMWC，小于150 kDa）。壳聚糖具有多种可应用于园艺作物的特性，如植物根系生长促进剂、抗菌、抗真菌和抗病毒活性。然而，这些特性取决于其分子量（MW）和乙酰化程度（DD）。因此，本文旨在广泛综述壳聚糖在农业领域的应用特性，并根据壳聚糖的分子量对其进行分类，以及其作为可持续农业材料的用途。
