Abstract

A coating agent containing chitosan for the seeds of vegetables including cabbage, cucumber, hot pepper, tomato, etc and containing chitosan, disperser, adhesive and surfactant. Its advantages include promoting growth of seedlings, preventing diseases and improving quality of vegetables.

Description

technical field [0001] The invention relates to a coating agent for vegetable seeds, in particular to a coating agent for vegetable seeds containing natural active substances. Background technique [0002] The coating agent of traditional vegetable seeds contains chemical pesticides, which are used to protect seedlings or prevent pests and diseases carried by seeds. Since the existence of chemical pesticides will cause environmental pollution problems, it is a subject of constant research to find a vegetable seed coating agent that can resist pests and diseases, increase production, and be friendly to the environment. [0003] Chitosan is the deacetylation product of chitin, and its chemical name is polyβ-(1,4)-2-amino-2-deoxy-D-glucose. Chitosan makes plants exhibit special biostimulatory behavior by activating plant cells, and has broad-spectrum antibacterial activity by triggering gene activation to produce fungal antibodies. Macroscopically, it ...
