Description
Technical field
The invention belongs to technical field of chemical fertilizer production, and in particular to a kind of chelating amino acids zinc fertilizer and preparation method thereof, special
It is not related to a kind of purplish red shepherd's purse chelating amino acids zinc fertilizer and preparation method thereof.
Background technology
Zinc is one of trace element necessary to plant growth, is the component or activator of a variety of enzymes, is primarily involved in plant
Breathe, the physiology course such as photosynthetic, redox reaction, and participate in the synthesis of the important substances such as nucleoprotein, auxin.Zinc-deficiency meeting
Crop production maldevelopment is caused, yield and quality is reduced, and intake of the human and animal to zinc can be influenceed indirectly, and then is influenceed
Body health.Application of zinc fertilizer is preventing and treating or the major measure for correcting crop zinc deficiency symptom.Because fertilizer of chelated zinc be difficult in soil by
Fixed, mobility and absorptivity in plant outclass Inorganic Zn fertilizer, therefore its stability and fertilizer efficiency are better than Inorganic Zn fertilizer.
In fertilizer of chelated zinc preparation process, prior art frequently with chelating agent have EDTA, humic acid and amino acid etc., profit
With these chelating agents with chelating divalent zinc ion, and then form fertilizer of chelated zinc.In above-mentioned chelating agent, though EDTA sequestering powers are strong,
But its cost is high, glyoxalic acid and formaldehyde etc. are easily degraded in soil, plant growth is endangered；Humic acid molecular weight is larger,
It is complicated, influence the absorption efficiency of its fertilizer of chelated zinc formed；Although amino acid will not produce harmful effect to plant,
It is that hydrolysis easily occurs because its sequestering power is weak, in plant or is inactivated easily being reacted with other anion, therefore causes it
The chelation percent of the fertilizer of chelated zinc formed is low, and stability is poor.Therefore, how the amino that a kind of stability is good, chelation percent is high is provided
Sour fertilizer of chelated zinc and preparation method thereof is a technical problem of those skilled in the art's urgent need to resolve.
The content of the invention
Therefore, the existing defect that chelating amino acids zinc fertilizer existence and stability is poor, chelation percent is low to be solved by this invention, enters
And chelating amino acids zinc fertilizer that a kind of stability is good, chelation percent is high, absorptivity is high and preparation method thereof is provided.
In order to solve the above technical problems, the technical solution adopted by the present invention is as follows：
Chelating amino acids zinc fertilizer provided by the present invention, includes the raw material of following parts by weight：
Further, the raw material of following parts by weight is included：
In addition, the present invention also provides the preparation method of above-mentioned chelating amino acids zinc fertilizer, comprise the following steps：
1) soluble zinc salt, amino acid, carboxymethyl cellulose, urea, pectin and water are mixed, obtains mixed liquor；
2) pH of the mixed liquor is adjusted, and is reacted；
3) to step 2) processing after mixed liquor be aged and filtered successively, obtain chelating amino acids zinc fertilizer.
Further, step 1) in, the gross mass of the quality of the water and the amino acid and the soluble zinc salt it
Than for (5-10)：1.
Further, step 2) in, adjust the pH to 3-5 of the mixed liquor.
Further, step 2) in, the reaction temperature of the reaction is 50-90 DEG C, the time is 2-4h.
Further, step 3) in, the temperature of the ageing is 50-90 DEG C, the time is 8-24h.
Further, step 1) in, the soluble zinc salt is zinc sulfate, zinc carbonate, zinc chloride, basic zinc sulfate and alkali
At least one of formula zinc carbonate.
Further, step 1) in, the amino acid is alanine, glycine, methionine, tryptophan, cysteine, Guang
At least one of propylhomoserin, leucine, isoleucine and serine.
Compared with prior art, the present invention has the advantages that：
(1) the chelating amino acids zinc fertilizer that the embodiment of the present invention is provided, using carboxymethyl cellulose and pectin, be first with
Hydrogen bond is formed between amino acid, the pericentral carboxymethyl cellulose of zinc and pectin for being looped around chelating amino acids using these,
