Liquid type leaf fertilizer synergist and preparation and application

Abstract

The invention discloses a liquid type leaf fertilizer synergist and preparation and application thereof. The liquid type leaf fertilizer synergist is prepared from gamma-polyglutamic acid, dodecyl betaine, polyacrylamide and water according to a certain ratio, and is prepared by the following steps of A, firstly, dissolving gamma-polyglutamic acid into the water, so as to obtain a solution; B, dissolving dodecyl betaine into the solution in step A, and slowly stirring; C, finally, feeding the polyacrylamide in an intermittent way, completely dissolving into the solution in step B, fixing the volume by distilled water, and uniformly mixing, so as to obtain the liquid type leaf fertilizer synergist. The liquid type leaf fertilizer synergist is applied into the application or preparation of leaf fertilizers, thereby solving the problem of influence to absorption of leaf fertilizer due to small attaching amount of leaf fertilizer dripped onto the cotton leaves and poor permeability. The liquid type leaf fertilizer synergist has the advantages that the attaching amount of leaf fertilizer dripped onto the cotton leaves is increased by 60% or above, the permeation rate of nitrogen elementin unit area is increased by 6% to 10%, and the permeation rate of potassium element in unit area is increased by 33% to 110%; after the liquid type leaf fertilizer synergist is added, the number ofboll treated by the leaf fertilizer is increased to 1.6, the output of unginned cotton is increased by 31.2kg per mou, and the output is increased by 11.9%.

Description

technical field [0001] The invention belongs to the technical field of fertilizer synergists, more specifically relates to a liquid foliage fertilizer synergist, and also relates to a preparation method of a liquid foliage fertilizer synergist, and also relates to a liquid foliar fertilizer Use of synergists. Background technique [0002] In the process of foliar fertilization, due to the influence of wax on the surface of plant leaves, foliar fertilizer droplets are not easy to adhere to the surface of the leaves. Therefore, the effect of foliar fertilization can be improved by adding surfactants and other additives. See: Wang Qiang, Wang Bang Jun.

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a kind of liquid type foliar fertilizer synergist, it is applicable to the crops represented by cotton, through indoor experiment and field plot test verification, has solved the problem caused by the hydrophobic structure of the blade surface of crop itself. The problem of difficulty in the attachment of foliar fertilizer droplets can significantly promote the attachment and penetration of foliar fertilizer nutrients such as urea, ammonium sulfate, calcium nitrate, potassium sulfate, potassium dihydrogen phosphate and dipotassium hydrogen phosphate on the cotton leaf surface, and promote Improve the absorption and utilization of nitrogen and potassium, and promote the growth and production of cotton
