Preparation and Application of a Novel Environmentally Friendly Organic Seed Coating for Rice

Chitosan was modified with sodium hydroxide and polymerized in water with plant growth regulators, microfertilizer and other additives to give a novel environmentally friendly seed coating agent for rice. The results showed the seed coating agent has obvious biological effect through the germination test, bacteriostasis test, toxicological security test and field experiment. Compared with the traditional rice seed coating agent, yield increasing rate increased 5%, the cost of raw materials consumption is reduced by 25%. The novel rice seed coating agent showing unique characteristics: excellent quality, high ratio of performance to price and environmentally friendly.
