Seed coating agent and coating method therefor

Abstract

The invention discloses a seed coating agent and a coating method therefor. The seed coating agent contains the following ingredients in parts by weight: 50-90 parts of super-absorbent resin, 10-30 parts of sustained-release fertilizer, 1-5 parts of rooting agent or rooting powder, 1-5 parts of insecticide, 1-5 parts of preservative agent, 1-5 parts of konjac flour and 1-5 parts of zinc sulfate powder. The coating method comprises the steps of firstly, weighing the konjac flour in parts by weight, preparing a dilute solution from the weighed konjac flour, then, spraying the dilute solution to seeds to be coated in a mist manner, then, uniformly mixing the konjac flour dilute solution sprayed seeds with polyacrylate so as to enable polyacrylate to be adhered to external surfaces of the seeds through the konjac flour dilute solution, and then, coating the seeds sequentially with the sustained-release fertilizer, the rooting powder or rooting agent, the insecticide, the preservative agent and the zinc sulfate powder. According to the seed coating agent and the coating method therefor, coatings can be used for improving properties of the seeds and have very good water absorptivity and water retentiveness, a relatively good preliminary water environment is provided in arid regions, and thus the percentage of seed germination can be guaranteed.

Description

technical field [0001] The invention relates to a seed coating agent and a coating method thereof. Background technique [0002] The current seeds, including coated seeds, have poor drought tolerance. When sowing by plane in deserts, barren beaches, sand dunes, high mountains and other arid areas, the seeds have poor drought tolerance, which leads to serious problems of low seed germination rate and survival rate. , directly affects the germination rate and survival rate of aircraft seeding in arid areas. Contents of the invention [0003] The purpose of the present invention is to provide a kind of seed coating agent and coating method thereof, not only the seed performance is improved to some extent, and the seed that uses this coating agent can be applicable to aircraft sowing, spraying, preferably solved the problem of seed. The counterweight problem, especially has good water absorption and water retention, and provides a better early water environment in arid areas,...
