Abstract

A natural seed coating agent extensively applicable to crops and grass seeds is formed from chitosan, oligochitosan derivative, glucosamine and alcohol aqueous solution. The seed coated with the saidcoating agent possesses the characteristics of promoting metabolism of plant cell, raising plant resistance to diseases, promoting development of root system, raising survival rate under the condition of drought, and increasing the output. The said seed coating agent is simple in preparation process, and is easy to implement industrilized production.

Description

technical field [0001] The invention relates to the agricultural application of a natural seed coating agent and a preparation method thereof. Background technique [0002] Seed coating technology has been widely used in agricultural production. The seed coating technology can promote germination to achieve uniform germination and increase the emergence rate; it has a certain water retention capacity for semi-arid soil; due to the addition of certain active substances, the plant has the ability to resist disease and lodging. Therefore, the use of seed coating technology can improve the survival rate of plants and achieve the purpose of increasing production. At present, the land desertification is serious in northern my country, especially the northwest region, and the annual rainfall is relatively low. In the restoration of the ecological environment in the west, there is an urgent need for seed coating technology suitable for regional characteristics, especially for grass...
