Problems solved by technology

However, this kind of dry powder seed coating agent is relatively simple, has no film-forming substances, lacks the detoxification of pesticides, has poor suspension after dilution with water, is easy to layer, and the coating is easy to fall off. Therefore, it is difficult to popularize and apply, and is accepted by people.

Abstract

The present invention relates to a production method of dry powder seed dressing agent for coating wheat, barley, maize, cotton, rice, forest wood and grass seeds. It selects and uses quick-dissolving resin with reticular structure as film-forming agent, uses the porous material with strong adsorptivity, light weight and good disintegrating property as pesticide carrier filling material, mixes them, adds interfacial agent and surfactant and makes the processes of pulverization, dispersion and detection so as to obtain the invented finished product.

Description

technical field [0001] The invention relates to a production method of rare earth dry powder seed coating agent, which is used for coating barley, wheat, corn, cotton, rice and forest grass seeds, and belongs to the field of agricultural technology. Background technique [0002] Seed coating agent is used for coating the seeds of barley, wheat, corn, cotton, rice and forest grasses, etc. It mainly improves the quality of good seeds, can improve the agricultural ecological environment, comprehensively prevents diseases and insect pests and also has micro-fertilizers. Before the present invention is made, in prior art, seed coating agent usually adopts dry powder seed coating agent, and dry powder seed coating agent mainly adopts compound composition such as chemical auxiliary agent, surface treatment agent and filler. When its dry powder seed coating agent is used, it needs to be diluted with water and coated in proportion. Since the seed coating agent is a dry powder, it ha...
