1 作蔬菜的土壤改良剂近年来,由于化肥、农药的不合理施用,有益昆虫减少,其残骸几丁质对土壤的供给随之减少,从而扰乱了土壤中微生物的分布,有用菌大量骤减,致使病虫害的发生日益加剧。由于壳聚糖中含有大量的N、C等元素,施入土壤中,可被微生物分解为植物所需的养分,还能形成通透性良好的高分子膜,改善和提高
1 as a soil conditioner for vegetables In recent years, due to irrational use of fertilizers and pesticides, useful insects decreased, the supply of debris chitin to the soil decreased, thus disrupting the distribution of soil microorganisms, a significant reduction in useful bacteria , Resulting in the growing incidence of pests and diseases. As chitosan contains a lot of N, C and other elements, applied to the soil, the microorganisms can be decomposed into nutrients needed by plants, but also the formation of a good permeability of the polymer film, improve and improve
