Abstract

The invention provides a method for rapidly preparing a multi-element amino acid foliar fertilizer by utilizing crustacean organisms. The method comprises the following steps: drying and crushing crustaceans, and mixing, grinding and refining the crushed crustaceans, lauryl sodium sulfate and sodium bicarbonate to obtain a material; adding alkali liquor for soaking, and then adding the material into a first-stage screw extruder to obtain first-stage filtrate and first-stage filter residues; adding the obtained filter residues into a second-stage screw extruder, and mixing the filter residues with an acid solution to obtain a second-stage filtrate; and feeding the first-stage filtrate, the second-stage filtrate and trace elements into a mixer for uniform mixing. According to the preparationmethod provided by the invention, the production cycle of preparing the multi-element amino acid foliar fertilizer from crustacean organisms is greatly shortened, continuous production is realized, and the development and application of the amino acid fertilizer are effectively promoted.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a method for rapidly preparing multi-element amino acid foliar fertilizers by using crustaceans. Background technique [0002] Amino acid fertilizer is a fertilizer containing amino acid substances. Amino acid exists in the fertilizer as the smallest molecule of protein, which is easy to be absorbed by crops; it also has the function of improving the disease resistance of fertilized objects and improving the quality of fertilized crops. Supplement essential amino acids for plants, stimulate and regulate rapid plant growth, promote plant growth and robustness, and promote the absorption of nutrients. Enhance the metabolic function of plants, improve photosynthesis, promote the development of plant roots, and accelerate plant growth and reproduction. Therefore, amino acid fertilizer has become a very important agricultural fertilizer. [0003] The production of amino acid fer...
