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...
