specific Embodiment approach 1

[0005] Specific embodiment 1: The pollution-free seed coating agent of this embodiment is made of 0.001 to 31% additives and a balance of chitosan and / or chitosan oligosaccharides with a volume concentration of 0.1 to 3% by mass percentage Wherein the additive consists of 0.001-8% insect antimicrobial peptide, 0.002-5% adenosine, 0.1-15% rhizobia or 0.0025-3% enzyme activity of 500-3000U, accounting for the total mass of the pollution-free seed coating agent One or several components in / mg of catalase.

[0006] The chitosan and chitosan oligosaccharides in the pollution-free seed coating agent of this embodiment can chelate with heavy metal elements in soil or water, reduce the absorption of heavy metal elements by plants, and indirectly avoid a large amount of heavy metal deposition in the human body.

specific Embodiment approach 2

[0007] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the additive consists of 0.001-8% of insect antimicrobial peptides and 0.0025-3% of the total mass of the pollution-free seed coating agent for 500-3000U / mg catalase composition. Others are the same as the first embodiment.

specific Embodiment approach 3

[0008] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the additive is adenosine acid accounting for 0.002-5% of the total mass of the pollution-free seed coating agent. Others are the same as the first embodiment.

[0009] The adenosine added in this embodiment can regulate the growth rate of plants, and promote the increase of yield and early maturity of crops.

Abstract

A seed coating agent without environmental pollution is proportionally prepared from the acid solution of chitosan and / or oligochitosan, and the additive chosen from the antibacterial peptide of insect, adenyl acid, rhizobia and hydrogen peroxidase through proportional mixing and stirring.

Description

technical field [0001] The invention relates to a seed coating agent and a preparation method thereof. Background technique [0002] Existing seed coating agents are often made of highly toxic substances to achieve the purpose of preventing and controlling pests, and their residues are extremely harmful to humans and animals, and long-term application of such seed coating agents will lead to enhanced drug resistance of pests and diseases , also pollute the soil and groundwater sources, and also destroy the normal flora in the soil. Contents of the invention [0003] The invention provides a pollution-free seed coating agent and a preparation method thereof in order to solve the defects that highly toxic substances seriously endanger human health and pollute the environment in the existing seed coating agent. The pollution-free seed coating agent is made of 0.001-31% of additives and the balance is 0.1-3% volume concentration of chitosan and / or chitosan oligosaccharide sol...
