Preparing method of seed soaking agent

Abstract

The invention relates to the technical field of pesticides, in particular to a preparing method of a seed soaking agent. A reaction film is prepared from alkali lignin and polyvinyl alcohol and wrapsseeds, and therefore diseases caused by bacteria are effectively restrained; since lignin and polyvinyl alcohol are soluble, the distance between polyvinyl alcohol molecules is increased, the hindrance of gas molecules is relatively reduced, diffusion is easy, and therefore the breathability of the thin film becomes larger; after a crosslinking agent is added, the hydroxyl reaction with lignin andthe hydroxyl reaction with polyvinyl alcohol are carried out, lignin molecules and polyvinyl alcohol molecules are integrated and are better in reaction, and the light permeability of the thin film is improved; due to the breathability and light permeability of the thin film, normal breathing of the seeds is not influenced; meanwhile, chitosan and the thin film can be combined to form water-retaining gel, and therefore the water retaining and drought resisting performance of the seeds is improved.

Description

technical field

[0001] The invention relates to the technical field of pesticides, in particular to a preparation method of a seed soaking agent. Background technique

[0002] China is a large agricultural country, and the growth of crops is related to the lives of the people. Therefore, how to regulate and promote the growth of various crops has always been a very noteworthy thing. However, today's environment has been damaged by industry, etc., and it is not suitable for the growth of crops. During the seedling stage, it is vulnerable to adversity such as drought, flood, and salinity. In the later stage of growth, problems such as lodging are prone to occur, resulting in a decline in yield. In order to solve the above problems, in addition to field management measures, common methods are seed coating, seed dressing and seed soaking. The production process of the seed soaking agent is simple, easy to use, and has a large processing capacity. It not only allows the seed...
