Embodiment 1
[0040] A liquid foliar fertilizer synergist, which is made from the mass concentrations of the following raw materials:
[0041]
[0042] A preparation method of a liquid type foliar fertilizer synergist, the steps are:
[0043] A, earlier γ-polyglutamic acid (500g) is dissolved in water, is prepared into solution;
[0044] B, then lauryl betaine (100g) is dissolved in the solution in step A, slowly stirs, reduces bubble generation;
[0045] C. Finally, polyacrylamide (400g) is fed intermittently, completely dissolved in step B, added distilled water to a constant volume (up to 1L) and mixed thoroughly to obtain a liquid foliar fertilizer synergist.
[0046] Through the above technical measures, we can obtain a liquid foliar fertilizer synergist with stable properties, which can be added after the foliar fertilizer is dissolved, or added before the foliar fertilizer solvent, or mixed with the foliar fertilizer Add simultaneously to dissolve.
Embodiment 2 to Embodiment 13
[0048] A kind of liquid type foliar fertilizer synergist, it is made by the mass concentration (g / L) of following raw material:
[0049] Raw materials and examples
[0050] Its preparation steps are identical with embodiment 1.
Embodiment 14
[0052] A kind of application of liquid type foliar fertilizer synergist in foliage fertilization, its steps are:
[0053] A. Dissolve the foliar fertilizer in water according to the volume ratio;
[0054] B. Add the foliar fertilizer synergist into the foliar fertilizer solution according to the concentration of 1mL / L, and spray on the foliage.
[0055] The application of the synergist in the above ratio in the application of foliar fertilizer is more conducive to the attachment and extension of foliar fertilizer droplets on the surface of the leaves, and at the same time accelerates the speed of nutrient ions in the foliar fertilizer passing through the waxy layer of the leaf surface. So as to achieve the purpose of increasing the effect of foliar fertilizer 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.
