Abstract

The invention discloses a special amino acid fertilizer-water paste for aquiculture and a preparation method thereof. The special amino acid fertilizer-water paste for aquiculture is prepared from the following raw materials in certain proportion: an amino acid solution, microelements, fermentation organic substances, inorganic fertilizers, minerals, a water quality improver, beneficial bacteria and a thickening agent. The preparation method comprises the following steps: A. production of amino acid solution namely, a. hydrolyzing; b. neutralizing; c. filtering; d. concentrating; B. production of fermentation organic substances: a. mixing: evenly mixing organic raw materials with the amino acid solution; b. inoculation: evenly mixing the organic raw materials with beneficial bacteria; c. fermentation; and C. production of amino acid fertilizer-water paste: a. chelation: heating the amino acid solution, adding microelements while stirring to perform chelation; b. mixing: sequentially adding the fermentation organic substances, inorganic fertilizer, minerals, water quality improver and beneficial bacteria, and evenly mixing; c. thickening: adding a thickening agent, and evenly mixing; d. inspection. The invention enhances the immunity of fish, reduces the occurrence of diseases, increases the culture yield of bighead, lowers the fish culture cost, and improves the fish quality.

Description

technical field

[0001] The invention belongs to the technical field of biological fish fertilizer, and more specifically relates to an amino acid fertilizer paste specially used for aquaculture, and also relates to the preparation of "waste water" in the production process of L-cystine, L-leucine and L-tyrosine A method for amino acid fertilizer and ointment. The fertilizer and water paste is an efficient and environmentally friendly biological fish fertilizer, which is suitable for freshwater aquaculture of various fish, shrimp, crab, shellfish, etc. Background technique

[0002] There are three main types of fertilizers commonly used in aquaculture, namely organic fertilizers, inorganic fertilizers, and biological fish fertilizers. Traditional organic fertilizers have their advantages, but the fertilizer effect is slow, the process of being used by plankton is longer, and a large amount of oxygen in the water body is consumed during the decomposition and mineralization pr...

Examples

preparation example Construction

[0072] A kind of preparation method of special amino acid fertilizer ointment for aquaculture, its steps are:

[0073] A. Production of amino acid solution (see attached figure 1 )

[0074] a. Hydrolysis ①

[0075] Hair (any one of human hair, pig hair, chicken feather, duck feather, goose feather, wool, cow hair): hydrochloric acid (28-31%) = 1:2, the temperature is controlled at 108 or 110 or 111 or 113 or 114 or 115 ℃, reaction time 6 or 7 or 8h;

[0076] b. Neutralization②

[0077] Neutralize to pH 4.8 or 4.9 or 5 or 5.1 with 99.9% liquid ammonia 40 or 43 or 46 or 48 or 51 or 55 or 58 or 61 or 64 or 66 or 68 or 70°C;

[0078] c. Filtration (including crude ③ and refined ④)

[0079] The filter cake extracts L-cystine, L-leucine, and L-tyrosine, and the filtrate is transferred to the concentration process for subsequent use;

[0080] d. Concentration⑤

[0081] Concentrate the filtrate to 28 or 29 or 30Be' at -0.06 or -0.07 or -0.08Mpa to obtain amino acid solution ⑥. ...
