Abstract

The invention discloses a preparation method of a nutritional fertilizer for preventing occurrence of plant leaf diseases. The preparation method comprises the following steps: mixing and crushing pig bristles, chicken feathers and human hair; screening by a sieve of 200 meshes and taking screened materials to obtain mixed crushed hair; using lipase for enzymolysis of lipid in the hair; then, acid-hydrolyzing the degreased hair in an aqueous solution of dilute hydrochloric acid with a pH value of 4.5-5.5 to obtain a first acid-hydrolyzed amino acid solution; acid-hydrolyzing the degreased hair in an aqueous solution of dilute hydrochloric acid with a pH value of 3.0-4.0 to obtain a second acid-hydrolyzed amino acid solution; using a compound enzyme of bromelain and neutral proteinase for continuing the enzymolysis to obtain an enzymolysis amino acid solution; mixing the first acid-hydrolyzed amino acid solution, the second acid-hydrolyzed amino acid solution and the enzymolysis amino acid solution, and decolorizing with modified activated carbon; and uniformly mixing magnesium sulfate, iron sulfate, zinc silicate, calcium superphosphate, copper carbonate, molybdenum nitrate, urea, monoammonium phosphate, potassium sulfate and decolorized amino acid hydrolyzate, and drying to prepare the nutritional fertilizer. After application of the fertilizer, plants basically do not have a phenomenon of leaf diseases.

Description

technical field [0001] The invention belongs to the technical field of plant fertilizers, and in particular relates to a preparation method of a nutrient fertilizer for preventing plant leaf diseases from occurring. Background technique [0002] Fertilizer is a kind of substance that provides crops with one or more essential mineral elements for plants, improves soil properties, and improves soil fertility. It is one of the material bases of agricultural production. In order to ensure the healthy growth of plants and increase the yield rate of plants, it is usually necessary to apply fertilizers to plants during the growth of plants. Because natural organic fertilizers have good effects and high safety performance, natural organic fertilizers are currently the most widely used. Amino acid organic fertilizers Fertilizer is a kind of natural organic fertilizer. Amino acid in amino acid organic fertilizer exists in the fertilizer as the smallest molecule of protein, which is be...
