Problems solved by technology

The traditional extraction method, enzymatic method and chemical synthesis method are difficult to achieve the purpose of industrial production due to the high cost of the precursor and the complicated process. The current process mainly uses microorganisms for direct fermentation, which has low cost and high yield
The amino acid waste liquid produced in the amino acid fermentation production process contains a large amount of nutrients, which can be absorbed and utilized by plants, but these amino acid waste liquids are often discharged as waste, which not only wastes resources, but also pollutes the environment
In addition, weathered coal, lignite or peat contain a large amount of humic acid, which can be absorbed and utilized as plant nutrie

Abstract

The invention discloses a soil improving synergistic saline-alkali resistant water soluble fertilizer and a preparation method thereof. The waste liquid generated in the amino acid fermentation production process is taken as a carrier, and added with active humic acid prepared from decomposed coal or brown coal or peat rich in humic acid, and then the mixture is thoroughly and proportionally mixed with water soluble nitrogen fertilizer, water soluble phosphatic fertilizer, water soluble potassic fertilizer, and macroelements and microelements such as copper sulfate, borax, zinc sulfate and ferrous sulfate; and then the final mixture is subjected to spray drying, separation and collection treatment, so that a powdery material is obtained; and as a result, the soil improving synergistic saline-alkali resistant water soluble fertilizer is formed. The soil improving synergistic saline-alkali resistant water soluble fertilizer provided by the invention is low in cost, low in investment, low in energy consumption, small in floor area, energy-saving, environment-friendly and free of pollution; zero emission of amino acid waste liquid and deep processing of the decomposed coal, the brown coal and the peat are realized and pollution on the environment is reduced; the waste is well utilized and changed into things of value; besides, the soil improving synergistic saline-alkali resistant water soluble fertilizer is good in water solubility, free of residue, rich in nutrition, high in active organic matter content and high in safety; and furthermore, the soil improving synergistic saline-alkali resistant water soluble fertilizer achieves the effects or improving the soil and resisting saline and alkali, and is obvious in synergia and wide in uses.

Description

[0001] Technical field [0002] The present invention involves a water -soluble fertilizer. Specifically, it is a method of modifying the water -soluble fertilizer and its preparation method of water -to -salt -alkali water -alkali water -soluble water, which is the field of fertilizer. Background technique [0003] Amino acid is a basic unit that constitutes protein. It is widely used in medicine, food and flavoring agents, animal feeds, and cosmetics.Traditional extraction methods, enzymes, and chemical synthesis methods Due to the high cost of the preface and complex craftsmanship, it is difficult to achieve the purpose of industrial production. Now the process is mainly fermented by microorganisms, low cost, and high output.The amino acid waste liquid produced during the production of amino acid fermentation contains a lot of nutrients and can be absorbed and utilized by plants. However, these amino acid waste liquids are often used as waste emissions, which not only wastes r...
