Chili seed coating agent and preparation method thereof

Abstract

The invention relates to a chili seed coating agent and a preparation method thereof. The chili seed coating agent comprises, by weight, 3-5 parts of gibberellin, 1-3 parts of auxin, 2-4 parts of indoleacetic acid, 5-7 parts of modified starch, 0.5-1 part of bone glue, 0.5-1 part of potassium sulfate, 0.1-0.3 parts of zinc sulfate, 0.5-1 part of curcumin, 2-3 parts of agarose, 1-2 parts of tolclofos-methyl 20% missible oil, 0.3-0.5 parts of carbendazim, and the balance of water. The preparation method comprises the following steps: placing the agarose, modified starch and bone glue in 100 parts of pure water, heating the agarose, modified starch, bone glue and water until boiling in order to dissolve the agarose, modified starch and bone glue in the water, cooling the obtained solution, keeping the temperature of the cooled solution at 60-65 DEG C, adding remaining substances in the above formula to the solution, uniformly mixing the remaining substances and the solution, and cooling the obtained solution to 40-50 DEG C in order to obtain the seed coating agent. The seed coating agent has the advantages of enhancement of the disease resistance of seeds, reduction of the mildew rate, shortening of the germination time, promotion of growth of seedlings, increase of the output of the crops, and improvement of the quality of products.

Description

[0001] Technical field: [0002] The invention relates to the technical field of agricultural planting, in particular to a capsicum seed coating agent and a preparation method thereof. [0003] Background technique: [0004] Seed coating, also known as seed coating agent, is made of pesticides (insecticides, fungicides, etc.), fertilizers, growth regulators, film-forming agents and supporting auxiliaries through specific processes, and can be directly or diluted It is a pesticide formulation that is coated on the surface of seeds to form a protective film with certain strength and permeability. [0005] The seed coating agent has the obvious effects of killing underground poisonous insects, preventing seedling sclerotia and seedling diseases, promoting healthy growth and development of seedlings, improving crop varieties, increasing seed germination rate, and reducing seed usage. Different from the fertilizers used in traditional seed soaking and seed dressing, the seed coatin...

AI Technical Summary

Problems solved by technology

General conventional seed dressing agents are easy to fall off and leached, the energy efficiency of target application is low, and it is not safe for humans and animals. Seed soaking or stuffing is only a plant protection measure for the disinfection of seeds, and seeds must be sown immediately after soaking or stuffing, and cannot be stored. Not a standard measure of breed

[0006] The research on seed coating technology in my country started relatively late. The existing capsicum coating agent formula is mainly made of fungicides, insecticides, agar, sodium alginate and auxiliary materials. The effect is relatively simple, and it generally improves the disease resistance of pepper seeds. effect, but it has little effect on improving seed disease resistance rate, reducing mold rate, shortening seed germination time, etc.
