Embodiment 1

[0022] A preparation method of amino acid water-soluble fertilizer includes the following steps:

[0023] (1) Acid-base hydrolysis: add acetic acid to the culture solution in an amount of 3.5% of the quality of the culture solution, and let it stand for 2.5 hours at a constant temperature of 28°C; then, add ammonia water to the culture solution in an amount of 4.5% of the culture solution's quality to adjust pH7.5-8, and stand for 1.5h at a constant temperature of 29℃;

[0024] (2) Enzymatic hydrolysis reaction: add mixed enzymes to the culture solution after acid-base hydrolysis, the added amount is 1.5% of the culture solution mass, after uniform mixing, stir 44min in a 31℃ thermostat to prepare enzymatic hydrolysis culture liquid;

[0025] (3) Fermentation of culture broth: Add mixed strains to the enzymolysis culture broth according to 3.5% of the mass of the enzymatic culture broth, mix them evenly, and place them in a fermentor for fermentation process;

[0026] The parameters ...

Embodiment 2

[0036] Comparing this embodiment 2 with embodiment 1, the steps change in the following aspects:

[0037] Step (1) Acid-base hydrolysis, in which the amount of acetic acid added is 4% of the mass of the culture solution, the acidolysis temperature is 30°C, and the time is 3h; the amount of ammonia added is 5%, the alkaline hydrolysis temperature is 31°C, and the time is 2h.

[0038] Step (2) Enzymatic hydrolysis reaction, wherein the added amount of mixed enzyme is 2% of the mass of the culture solution, enzymatic hydrolysis is performed at 33° C., and stirring is performed for 47 minutes.

[0039] Step (3) Fermentation of culture broth, the fermentation parameters are:

[0040] Carry out aerobic fermentation first, the temperature rise of the fermenter is 5℃ / 30min, the temperature reaches 37℃, cultivate for 3h, the dissolved oxygen in the culture solution is 6L / min; then carry out anaerobic fermentation, stop the dissolved oxygen, and ferment The tank was evacuated to a vacuum, the f...

Abstract

The invention discloses a preparation method of amino acid water soluble fertilizer. The preparation method comprises the steps of: 1) acidic and alkaline hydrolysis: performing acidic and alkaline hydrolysis on a culture solution respectively with acetic acid and ammonia water; 2) an enzymolysis reaction: adding a mixed enzyme accounting for 1.5-2% by mass of the culture solution, and performingenzymolysis at 30-34 DEG C; 3) culture solution fermentation: adding a mixed bacterial strain accounting for 3.5-4.5% by mass of the enzymolyzed culture solution, and performing aerobic fermentation and anaerobic fermentation; 4) decolorizing: adding active charcoal to decolorize the fermented solution; 5) drying and pulverization: drying the fermented solution at low temperature and pulverizing the dried solution to produce amino acid powder; and 6) dissolution and chelating: weighing water, the amino acid powder, ferrous sulfate heptahydrate, copper sulfate pentahydrate, zinc sulfate heptahydrate, manganese sulfate monohydrate and instant dissolving boron, and stirring the components to chelate the metal ions, thus producing the amino acid water soluble fertilizer. The preparation methodhas high protein hydrolysis rate and amino acid yield. The amino acid water soluble fertilizer can promote growth of plants and increase the yield per Mu.

Description

Technical field [0001] The invention belongs to the technical field of fertilizer processing, and specifically relates to a preparation method of an amino acid water-soluble fertilizer. Background technique [0002] Amino acid water-soluble fertilizer is a high-tech, multi-functional and environmentally-friendly amino acid liquid fertilizer produced by biological fermentation technology and membrane concentration technology using agricultural and sideline product resources as the main raw material; it is rich in active peptides, amino acids, calcium, and natural growth active substances. Amino acid water-soluble fertilizer is a multi-functional water-soluble fertilizer suitable for the production of green agricultural products in modern agriculture. The main difference between it and general water-soluble fertilizer is that in addition to adding trace elements, it also adds essential amino acids during the growth and development of crops, and it can be more fully balanced It supp...
