Seed coating agent, and preparation method and use thereof

Abstract

The invention provides a seed coating agent and a preparation method thereof. The raw materials of the seed coating agent comprise an imidazole bactericide, sodium alginate and diatomite. The seed coating agent can substantially reduce the club root incidence of cruciferous crops, has the advantages of high efficiency, low toxicity, low residue, use safety, environmental protection and simplification of the club root prevention and treatment program, and adapts to the mechanized sowing demand.

Description

technical field [0001] The invention belongs to the technical field of agricultural seed treatment, and in particular relates to a seed coating agent for cruciferous crops and a preparation method thereof. Background technique [0002] Seed coating refers to the use of adhesives or film-forming agents to wrap non-seed materials such as fungicides, insecticides, micro-fertilizers, plant growth regulators, colorants or fillers on the seeds with a specific seed coating machine. Outside, it is a seed technology to make the seeds spherical or basically maintain the original shape, improve stress resistance and disease resistance, accelerate germination, promote seedling formation, increase yield and improve quality. The seed coating agent can quickly solidify and form a film, so it is not easy to fall off. Seeds coated with seed coating agent can quickly absorb water and swell after sowing. With the gradual development of the embryo in the seed and the continuous growth of the ...

Problems solved by technology

However, both physical and chemical control are time-consuming and labor-intensive, and long-term application of lime powder will cause soil compaction

Among them, the spraying or root irrigation adopted by chemical control usually needs to be carried out 2-3 times, and the amount of medicament is large, and the labor cost is high; Seeding; if the application period and concentration of some chemicals are unreasonable, especially when the plants are transplanted, if the roots of the plants have wounds or are in the young stage, irrigation with extremely low concentrations of chemicals will also cause growth retardation or even death of the plants; in addition, a large number of Soil chemical treatment will cause the chemical to penetrate directly into the soil or groundwater, which will not only cause environmental pollution, but also bring harm to human health
