example 1

[0013] Add 100kg of animal fur, add 200kg of sulfuric acid with a concentration of 25%, heat to 110°C under normal pressure, keep for 7 hours, cool to 60°C, add NaOH to neutralize until the pH reaches 5.2, filter to remove impurities to obtain about 310kg of amino acid stock solution, then reduce Concentrate under pressure to precipitate Na 2 SO 4 , cooled and filtered to obtain amino acid mother liquor; FeSO was added to the mother liquor 4 6kg, heat to 70°C for chelation for 2 hours, cool, add KH 2 PO 4 30kg, and 2.5kg of potassium fulvic acid was stirred to obtain a compound amino acid foliar fertilizer for mulberry.

example 2

[0015] 100kg of animal fur, add 240kg of hydrochloric acid with a concentration of 25%, heat to 110°C under normal pressure, keep for 7 hours, cool to 60°C, add NaOH to neutralize until the pH reaches 5.2, filter to remove impurities to obtain about 350kg of amino acid stock solution, and then Concentrate under reduced pressure to precipitate NaCl, cool and filter to obtain the amino acid mother liquor; add FeSO to the mother liquor 4 8kg, heated to 70°C for chelation for 2 hours, cooled, and added KH 2 PO 4 32kg, potassium fulvic acid 3.0kg stirs, and the compound amino acid foliage fertilizer that is used for mulberry is obtained.

Abstract

The invention belongs to the technical field of producing of agriculture bio-fertilizers and biological pesticide products. The invention discloses a preparation method of a paper mulberry tree foliage fertilizer. The foliage fertilizer is implemented by dissolving a composition consisting of amino acids, FeSO4, KH2PO4 and fulvic acid potassium into water, and spraying the fertilizer to the paper mulberry tree leaf surfaces. The preparation method is characterized in that: animal protein serving as a raw material is hydrolyzed, neutralized and desalted to obtain a composite amino acid stock solution, then the FeSO4 is added into the stock solution for chelation, and then the KH2PO4 and the fulvic acid potassium are added into the stock solution to form the amino acid composite foliage fertilizer. By using the preparation method, the utilization ratio of the foliage fertilizer on leaf surfaces can be increased, the nutritional needs during the key growth and development period of paper mulberry trees are met, and the yield and the quality of paper mulberry tree leaves can be increased.

Description

technical field [0001] The invention belongs to the production technology of agricultural biological fertilizer and biological pesticide products, and relates to a preparation method of amino acid compound foliar fertilizer for tree-forming. Background technique [0002] Since the 1930s, advanced countries in the world have developed and produced the first generation of foliar fertilizers, mainly selecting inorganic salts with good solubility and compatibility. Its disadvantages are insufficient solubility, low absorption and utilization rate, insufficient spreading wetness, and simple and unreasonable nutrient composition. Since the 1970s, according to the mechanism of foliar absorption of nutrients, developed countries in the world have developed high-concentration compound foliar fertilizers based on chelated trace elements, which are characterized by the selection of organic and efficient chelated nutrients. High-efficiency concentrated type synthesized by chemical reac...
