Preparation method of synergist

Abstract

The invention relates to a preparation method of a synergist. The method is characterized in that: the synergist is composed of the following materials by weight: 10-20 parts of AEO-3, 10-20 parts of AEO-9, 5-10 parts of span-80, 10-20 parts of sorbitol and 10-20 parts of glycerol. The synergist prepared by the method provided by the invention can obviously reduce the liquid surface tension, has strong permeability and moisture retention, and can obviously improve the utilization rate of foliar fertilizers and pesticides.

Description

technical field [0001] The invention relates to a preparation method of a synergist. Background technique [0002] The Ministry of Agriculture has formulated the "Action Plan for Zero Growth in Fertilizer Use by 2020" and "Action Plan for Zero Growth in Pesticide Use by 2020". synergist. [0003] The leaves of plants and the epidermis of animals have a layer of lipid protective film. It is difficult to achieve satisfactory results due to the problems of high surface tension, weak permeability, and short moisture retention time for foliar fertilizers or pesticides dissolved in water. When using surface fertilizers and pesticides, synergists need to be added to improve fertilizer efficiency and drug efficacy. At present, the synergists of foliar fertilizers and pesticides are mainly organosilicon series. The price of organosilicon series is expensive, and the additional cost even exceeds the fertilizer and pesticide itself. Therefore, the market needs a synergist with high q...

AI Technical Summary

Problems solved by technology

At present, the synergists of foliar fertilizers and pesticides are mainly silicone series, which are expensive, and the additional cost even exceeds the fertilizer and pesticide itself, so the market needs a high-quality and cheap synergist
