Organic sylvite water soluble fertilizer

Abstract

The invention relates to the technical fields of agricultural planting and fertilizer, in particular to organic sylvite water soluble fertilizer and a preparation method thereof. The method comprisesthe following steps: accurately taking citric acid, acetic acid and formic acid to prepare a primary solution; accurately taking potassium hydroxide and magnesium oxide to be added into the primary solution, so as to form a secondary solution; accurately taking urea malic acid, urea phosphate, potassium fulvic acid, potassium humate, potassium nitrate, boric acid, zinc lignosulphonate, iron lignosulphonate, a root growth promoting agent, a chitosan solution, molasses and amino acid, and mixing the materials with the second solution, so as to finally form an organic sylvite water soluble fertilizer finished product. The organic sylvite water soluble fertilizer aims at providing fertilizer which can activate soil microbial reproduction, improve soil ecological environment and continuously and harmoniously supply potassium nutrition for agricultural production, thereby improving the crop yield and quality; in addition, the organic sylvite water soluble fertilizer can greatly improve the utilization of fertilizer.

Description

technical field [0001] The invention relates to the technical field of agricultural planting and fertilizers, in particular to a water-soluble potassium organic acid fertilizer. Background technique [0002] The types of potassium fertilizers currently used in agricultural production mainly include potassium chloride, potassium sulfate, potassium nitrate, and compound fertilizers containing potassium sulfate or potassium chloride. Potassium chloride and potassium sulfate are physiologically acidic fertilizers, which will cause soil acidification after being applied to the soil, while the nitrate in potassium nitrate is easy to lose in the soil, and cannot provide continuous nitrogen nutrition to crops. At the same time, the excessive application of inorganic chemical potassium fertilizers will lead to the increasing shortage of soil microorganisms, break the ecological balance of soil microorganisms, simplify the species of microorganisms, reduce the population of beneficial...

Problems solved by technology

[0003] The potassium humate fertilizer that can be used as organic acid potassium fertilizers for crop cultivation at present has an organic acid of a single component, which is essentially different from the composition of various organic acids of the present invention; the magnesium fertilizer applied to crop cultivation is mainly It is magnesium sulfate, which is a physiologically acidic fertilizer, which will cause soil acidification after application

[0004] Existing potassium humate fertilizers are not designed to meet the potassium nutrient requirements of crops, and humic acid is a substance with an uncertain molecular structure. This substance can maintain the continuous supply of soil potassium fertilizer, but it does not have the function of activating the reproduction of soil microorganisms
