Abstract

The invention belongs to the fields of high-molecular chemistry and agricultural seed coating agent. The invention specifically provides an application of an organosilicon-modified high-molecular compound as a seed coating film-forming agent. The invention specifically provides an application of the high-molecular compound represented by the general formula (I) as a seed coating film-forming agent. The film-forming agent provided by the invention has good water resistance and water permeability, such that different requirements by upland fields and paddy fields can both be satisfied. A seed coating agent prepared with the film-forming material provided by the invention satisfies requirements for both viscosity and strength. Expulsion rate, viscosity and fluidity of the seed coating agent are substantially improved, and the seed coating agent has good gloss and brightness.

Description

technical field [0001] The invention belongs to the fields of macromolecular chemistry and agricultural seed coating agent, and specifically relates to the application of an organosilicon-modified macromolecular compound as a film-forming agent for seed coating. Background technique [0002] Film-forming agent for seed coating (referred to as film-forming agent) is a substance that can adhere active components such as pesticides, micro-fertilizers, growth regulators and sustained-release agents in seed coating agents to the surface of seeds and solidify to form a film. [0003] Generally, different seed coating formulations contain different components, which generally include active components and inactive components. Among them, the active components mainly include insecticides, fungicides, plant growth regulators, fertilizers and beneficial microorganisms, etc., which are active ingredients that directly play a role in the seed coating agent, and their type, composition a...
