Method for coating seeds by combined use of active soil, adsorbing and flocculating agent and coating agent

Abstract

The invention discloses a method of bagging seed coat that utilizes composite active earth, adsorption and flocculent for seed, and the bagging-coat agent. Wherein active mineral earth, starch and chitosan, poyacrylamide composite, together with pesticide and chemical fertilizers are utilized for seed coat bagging.

Description

technical field [0001] The method relates to a seed coating method and a coating agent, in particular to a seed coating agent composed of an active compound and a polymer, which can prolong the effective action time of the coating. Background technique [0002] Over the years, there have been two thorny problems in my country's agricultural production: [0003] 1. The utilization rate of chemical fertilizers in my country is very low, nitrogen, phosphorus, and potassium fertilizers are 25% to 30%, 10% to 25%, and 35% to 50%, respectively. At present, the amount of chemical fertilizer used per hectare in my country has reached 240 kg, and the amount of fertilizer applied per unit area has reached 1.6 times the world average. As the amount of fertilizer application increases, there will also be a diminishing return effect. The utilization rate of chemical fertilizers in my country is much lower than that of developed countries, and the annual loss of nitrogen due to fertiliz...

Problems solved by technology

[0004] 2. The underground diseases and insect pests in my country are serious, which reduces the germination rate of seeds and affects the yield of crops

[0008] 1. Most of the coating agents used in the prior art are not friendly to the soil environment, and a large amount of use will destroy the ecological balance of the soil

[0009] 2. The thixotropy of the coating is poor, and the coating is easy to fall off during transportation and sowing

When the seeds germinate, after the coating is broken and falls off, it is difficult to continue to play its role, that is, it cannot play the role of sustained release of medicine and fertilizer, water conservation and moisture conservation for a long time.
