Abstract

The invention discloses an application of an organic silicone modified high-molecular compound as a seed coating film former. The organic silicone modified high-molecular compound has a molecular structure fragment described in a general formula (I): definitions of all groups in the formula are described in the instruction. The film former with a reticular structure is formed by the crosslinking reaction of the molecular structure fragment in the general formula (1) and a soluble film forming material containing hydroxyl, amino, carboxyl, alkoxy and amide groups. The film former has good water resistance and water permeability, and can simultaneously meet the different requirements of a dry field and a paddy field. A seed coating agent prepared by adopting the film forming material meets the requirements on both viscosity and strength, has significant improvement on expulsion rate, viscosity and liquidity, and simultaneously has relatively high brightness and vividness.

Description

Technical field [0001] The invention belongs to the field of polymer chemistry and agricultural seed coating agents, and relates to the use of an organic silicon modified polymer compound as a seed coating film-forming agent. Background technique [0002] The film-forming agent for seed coating (referred to as the film-forming agent) is a substance that can adhere the active components such as pesticides, micro-fertilizers, growth regulators and slow-release agents in the seed coating agent to the surface of seeds and solidify into a film. [0003] Generally, different seed coating formulations contain different components, which can be summarized as active components and inactive components. Among them, the active ingredients mainly include insecticides, fungicides, plant growth regulators, fertilizers and beneficial microorganisms, etc., which are the effective ingredients that directly play a role in the seed coating agent, and their type, composition and content directly reflec...
