Environment-friendly type seed coating film-forming agent and preparation method thereof

Abstract

The invention discloses an environment-friendly type seed coating film-forming agent and a preparation method thereof. The film-forming agent consists of 0.1-1.8% of attapulgite, 0.005-0.01% of film-forming accessory ingredient, 0.5-6% of emulsifying wetting suspending agent, 0.6-4% of penetrating agent, 0.02-0.08% of preservative, 2.0-6.0% of freeze proof agent, 0.05-0.6% of viscosity stabilizing agent, 0.1-0.7% of warning color and 80.81-96.625% of water. The preparation method comprises the steps of: adding the attapulgite into the water with the quality volume ratio of 1:20; adding the emulsifying wetting suspending agent to obtain attapulgite suspension liquid; adding the film-forming accessory ingredient into boiling water with the quality volume ratio of 1 / 500 to obtain cleaning liquid; adding the penetrating agent, the preservative, the freeze proof agent and the viscosity stabilizing agent into the cleaning liquid to obtain mixture; adding the attapulgite suspension liquid into the mixture, and adjusting the pH value to be 6.2-7.2; and adding the warning color and compensating the water to be total weight, and grinding to obtain the film-forming agent. The film-forming agent is environment-friendly, can adjust the loading quantity, can adjust the growth microenvironment of seeds, and has stable performance and low price.

Description

technical field [0001] The invention relates to an environment-friendly seed coating film-forming agent and a preparation method thereof, which can be compounded with various pesticides, micro-fertilizers and plant growth regulators to form a multifunctional seed coating agent. Background technique [0002] As we all know, a seed coating agent is a substance that is used for coating crops or other plant seeds and has film-forming properties. It generally consists of two parts: ① Active ingredients added as required, which mainly refer to various insecticides, fungicides, micro-fertilizers, plant growth regulators (hormones), etc. in seed coatings. These active ingredients are seed coatings. The main body of the agent, it is precisely because of these active ingredients that the seed coating agent has the functions of improving the germination rate of seeds, promoting the growth of seedlings, and preventing insects and diseases; ), which mainly includes colloidal dispersants...

AI Technical Summary

Problems solved by technology

[0004] At present, the seed coating film-forming agents used are generally made of synthetic or natural polymer materials with adhesive and film-forming properties; when selecting such substances, if the molecular weight is low (such as polyethylene glycol, etc.), It is easy to dissolve in water when soaking seeds, causing the dissolution and loss of coated pesticides, plant growth regulators, nutrients, etc., and the coating effect cannot be achieved well; if the molecular weight is too high, the active ingredients cannot be released, and the seeds and the outside The exchange of soil substances hinders the growth of seeds; at the same time, the biggest disadvantage of this type of film-forming agent is that the polymer substances used are difficult to degrade naturally. Long-term use may poison the soil and eventually cause soil compaction

[0005] In order to solve this problem, researchers proposed to use some water-soluble polymer materials such as chitosan as a film-forming agent to use its degradability to reduce the toxicity to the soil, but the expensive price of chitosan hindered its application. to promote
