Production method of compound amino acid chelated liquid fertilizer based on earthworm enzymolysis

Abstract

A compound amino acid chelated liquid fertilizer based on earthworm enzymolysis is characterized by comprising the steps: firstly, cleaning earthworms, defecating, spitting mud and freeze-drying to obtain dry earthworms; then carrying out Soxhlet extraction, deestering and deodorization of the dried earthworms with anhydrous ethanol and acetone, crushing and grinding to prepare a slurry, and carrying out enzymolysis to obtain an earthworm amino acid solution; and finally, taking the earthworm amino acid solution as a chelating agent, chelating with iron, zinc, manganese and copper trace elements, and supplementing macroelements needed by crops, to obtain the compound amino acid chelated liquid fertilizer based on earthworm enzymolysis. The earthworm enzymolysis solution is added in the liquid fertilizer, and the liquid fertilizer is rich in a variety of amino acids, is a natural chelating agent, has the advantages of high chelation rate and stable chelate compound, is easily absorbed by the crops, promotes crop growth and development, increases both production and income, and improves the quality.

Description

technical field

[0001] The invention belongs to the field of fertilizers, and in particular relates to a production method of liquid fertilizers based on earthworm enzymolysis and chelation of compound amino acids. Background technique

[0002] Foliar fertilization is an important complement to soil fertilization techniques. Foliar fertilization breaks the traditional method of soil root fertilization, and can be said to be the most flexible and convenient way of fertilization. However, in recent years, most of the domestically produced foliar fertilizers have low effective content, single nutritional function, low element utilization rate, and unstable effect. Whether the scientific and technological content of foliar fertilizer is high or not depends on whether it can increase farmers' production and income. This requires foliar fertilizer to provide as many nutrients as possible, high multivariate micro-fertilizers, sufficient amounts of effective amino acids and Highly...
