Rice seed treating agent and preparation method thereof

Abstract

The invention discloses a rice seed treating agent. The rice seed treating agent is prepared from, by weight, 20-35 parts of clothianidin, 15-28 parts of chitosan oligosaccharide, 18-30 parts of aminooligosaccharide, 10-16 parts of gibberellin, 18-30 parts of sodium lignosulfonate, 12-20 parts of derris root powder, 5-10 parts of pyrethrum extracts, 22-36 parts of a dispersing agent, 15-28 partsof a film forming agent, 5-12 parts of a defoaming agent, 8-14 parts of a thickening agent, 15-20 parts of an anti-freezing agent and 300-500 parts of water. The invention also discloses a preparationmethod of the treating agent. The preparation method comprises the following steps of mixing clothianidin, clothianidin ammonia, oligosaccharin, gibberellin, sodium lignosulfonate, the dispersing agent, the defoaming agent, the anti-freezing agent and the water; performing ultrasonic dispersion, sequentially adding the derris root powder, the pyrethrum extracts, the film forming agent and the thickening agent, and then conducting ultrasonic dispersion to obtain the treating agent. The treating agent can achieve sterilization, pest extinguishment and disease resistance, promote seed germination, improve the quality of the rice and increase the yield of the rice.

Description

technical field [0001] The invention belongs to the technical field of rice breeding, and in particular relates to a rice seed treatment agent and a preparation method thereof. Background technique [0002] Rice is the main food crop in my country. The improvement of rice quality and yield has attracted more and more attention. Whether rice can grow stably plays a vital role in my country's food security. Plant diseases and insect pests during the rice growth period are the main threats to the safe production of rice, and rice seeds carry a variety of pathogens, which are an important way for the spread of rice plant diseases and insect pests. In production, rice seeds must be sterilized before sowing. Seed treatment is a very popular means of crop protection in the world today. It mainly uses seed treatment agents to treat crop seeds to prevent pests and diseases, or improve seed germination quality, promote root development, and improve seedling stress resistance.

AI Technical Summary

Problems solved by technology

Although many seed treatment agents in production can improve seed resistance to a certain extent, most of them focus on the effects of seed resistance to diseases and insects, and their effects on increasing yield and growth are not very satisfactory.
