A biological seed coating agent for controlling soybean phytophthora root rot, a preparing method thereof and a using method of the seed coating agent

Abstract

The invention provides a biological seed coating agent for controlling soybean phytophthora root rot, a preparing method thereof and a using method of the seed coating agent and belongs to the technical field of agricultural biotechnology. The seed coating agent comprises 20% by mass of streptomyces dorenlacusensis M1-4 inoculum, 10% by mass of a plant activator, 5% by mass of a biological conditioning agent, 10% by mass of a nutrition element solution and 10% by mass of an auxiliary agent, with the balance being water. The preparing method includes adding 1% of carboxymethylcellulose sodium and 10% of polyvinyl alcohol into water, heating to 80 DEG C, stirring for 20 min until film forming agents are fully dissolved, cooling to room temperature, adding 0.4% of rhodamine, 3% of glycerol and 0.5% of peregal O-25, and adding 20% of the actinomycete streptomyces M1-4 inoculum, 5% of the biological conditioning agent, 10% of the nutrition element solution, 10% of the plant activator and the water into the auxiliary agent according to mass percentages of components in the seed coating agent. The seed coating agent significantly inhibits soybean diseases and pests, can increase the root shoot ratio, can increase soybean stress resistance and can increase soybean quality and yields.

Description

technical field [0001] The invention belongs to the technical field of agricultural biology, and in particular relates to a biological seed coating agent for preventing and controlling soybean Phytophthora root rot and its preparation method and application method. Background technique [0002] The start of seed coating technology was in the 1930s. The British Germain Seed Company successfully developed a seed coating agent for the first time on crops. In the early 1980s, the Soviet Union developed a combination of polymer aggregate adhesive and plant growth regulator. The finished seed coating agent, and the technology of seed coating agent has developed by leaps and bounds. At present, the seed coating technology and degree of the developed agricultural countries in the world are very high, including corn, rice, wheat, soybean, millet, vegetables, cotton, peanuts, vegetables and so on. [0003] The research and application of seed coating agents in China has developed rap...

Problems solved by technology

These chemical seed coating products generally have single ingredients, or one-sided functions, or are highly toxic, and there are certain risks and hazards during use.

Although a small amount of biological seed coating agents have appeared on the market at present, which has solved the problem of residual toxicity of seed coating agents, the effect on disease and insect control is not significant
