Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1, the present invention provides a technical solution: the preparation method of the amino acid nitrogen fertilizer is characterized by comprising the following steps: the method comprises the following steps: collecting and preparing keratin for later use; step two: acidolysis, namely performing acidolysis reaction on the keratin in the step one to obtain amino acid stock solution; step three: extracting target amino acid in the amino acid stock solution to obtain target amino acid solution; step four: neutralizing alkali, namely adding liquid ammonia or sodium hydroxide solution into the target amino acid stock solution to neutralize excessive acid in the target amino acid stock solution; step five: separating and purifying to separate harmful substances in the target amino acid stock solution after alkali neutralization treatment; step six: concentrating, namely concentrating the target amino acid stock solution in the step five to obtain a concentrated stock solution; step seven: adding calcium and magnesium into the concentrated stock solution in proportion, heating to 60 ℃, and carrying out a decocting reaction for 4-6 hours; step eight: refining, adding potassium fulvate, humic acid and amino acid, heating to 60 ℃ and reacting for 0.5-1 h to obtain a liquid amino acid nitrogen fertilizer; spin-drying the liquid amino acid nitrogen fertilizer to be powdery by using a centrifugal machine to obtain a solid final product; or directly metering and packaging to obtain liquid final product.
Preferably, the keratin comprises one or more of feather, hair, livestock skin, animal hoof and foot, and the like, and is washed with clear water before acidolysis.
Preferably, the target amino acid includes 17 kinds of amino acids such as leucine, isoleucine, phenylalanine, lysine, threonine, methionine, tryptophan, histidine, tyrosine, valine, alanine, serine, glycine, arginine, aspartic acid, cysteine, glutamic acid, etc.
Preferably, the hazardous substances separated in step five include heavy metals and catalyst residues used in the reaction.
Preferably, in the combined reaction of the seventh step, the amount of calcium and magnesium to be added is determined according to the requirements of unshelling the shrimps and the growth of the shrimps and beneficial plankton.
Preferably, the acidolysis reaction uses hydrochloric acid to react with the keratin.
The action mechanism of the amino acid nitrogen fertilizer for inhibiting (or preventing and killing) the moss is as follows: the amino acid nitrogen fertilizer can culture beneficial algae groups in water, and can inhibit the growth of moss after the beneficial algae groups have population advantages, and the principle is the same as that of the rice field which has more seedlings and can inhibit the growth of weeds after the seedlings grow. The beneficial algae group is propagated in a large amount, the transmittance of water can be reduced, and the moss growth can be inhibited when the light in the water is insufficient. The amino acid nitrogen fertilizer can kill moss, the action mechanism is that the water in a single moss body is destroyed, and like the principle of pickling vegetables with salt, the water in the vegetables permeates into the vegetables like the salt to cause water loss. It is more likely that we have not completely clarified the principle that amino acid nitrogen fertilizers kill moss, but have not hindered its realization of beneficial effects.
Amino acid in the amino acid nitrogen fertilizer can be directly absorbed and utilized by shrimps and beneficial alga groups, the utilization of the amino acid nitrogen fertilizer by the shrimps is equivalent to providing bait, and meanwhile, the physique and the stress response capability of the shrimps are improved. The fertilizer is utilized by beneficial algae, promotes the propagation of the beneficial algae, improves the dissolved oxygen in water, reduces the transmittance of water, inhibits the growth of moss, and adds a small amount of potassium fulvate, humic acid, calcium, magnesium and the like into a product along with the optimization of a formula in an amino acid nitrogen fertilizer, thereby being more beneficial to the propagation of the beneficial algae and the shelling growth of shrimps.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
