Grass seed coating agent and coating process

Abstract

The invention belongs to the technical field of seed coating, in particular relates to a grass seed coating agent and a grass seed coating process. The invention discloses the grass seed coating agent and the grass seed coating process. The coating agent contains a water-soluble mixture and water-insoluble solid particles. The weight of a grass seed prepared from the coating agent by the coating process can be increased by 15 to 100 percent, a coating layer is difficult to break, sowing performance can be improved, planting difficulty is reduced and the germination and growth state of the seed are improved. The process has the characteristics of convenient operation and short time.

Description

technical field [0001] The invention relates to the technical field of seed coating, in particular to a pasture seed coating agent and a coating process. Background technique [0002] Seed coating technology is a high-tech in the agricultural field. According to the degree of weight increase after seed coating, it can be roughly divided into three types. One is film coating, which is coated with a layer of pesticides, fungicides, and compound fertilizers on the surface of the seeds. , plant growth regulator, slow-release agent, film-forming agent and other ingredients are processed into a multi-effect fertilizer compound, and the increase in seed coating agent accounts for about 1% to 3% of the seeds. The second is pelletized coating, which is to attach small seeds or seeds with irregular surfaces (such as flat, awned, thorny, etc.) to the surface of the seeds through a pellet machine to attach additives and powdery inert substances. On the basis of changing the biological ...

Problems solved by technology

[0003] Many forage seeds are very small, such as white clover, red clover, and alfalfa in legumes, and bermudagrass, zoysia, bluegrass in grasses, etc., which often cause difficulties in planting and can be enlarged by coating. The volume and weight of the seeds can be convenient for the grower to sow. Domestic reports on forage seed coating technology are mostly pelletized coating technology. For example, the application number is 0012548.2 Chinese invention patent discloses a kind of forage seed pelletized seed coating agent and coating process; the Chinese patent No. 200410009184.4 discloses a plant seed pellet coating seed coating agent, pellet coating process and pellet coating seeds, although forage seed pelletization can solve the problem of aerial sowing of forage grass seeds drifting with the wind However, the cost of pellet coating is high and takes a long time, which is not conducive to the coating production of large quantities of forage seeds
