Description
Technical Field
The invention relates to the field of auxiliaries, and particularly relates to a stabilizer for an amino acid fertilizer and application thereof.
Background
The amino acid has wide sources and unique biological properties, and is often added into fertilizer products to increase photosynthesis of plants, promote fertilizer efficiency absorption, increase fruit quality, improve soil, enhance metabolism, resist stress and the like, so that various water-soluble fertilizers containing amino acid can be produced at the same time. The amino acid water-soluble fertilizer has the following characteristics: the added amino acids have various types, large addition amount of the amino acids, large difference of hydrophilicity and hydrophobicity of the amino acids, large difference of solubility in water, wide range of isoelectric points of the amino acids, wide range of pH values, various fertilizers, large addition amount, high salt content and the like. Potassium salt, phosphorus salt, magnesium salt, calcium salt and other medium and trace element salts in the existing amino acid fertilizer are easy to generate the problems of crystallization, precipitation, delamination and the like after being mixed with amino acid. Meanwhile, the fertilizers have the problems of poor compatibility of pesticide and fertilizer, poor wetting and penetrating effects, high foamability and the like.
The prior common method is to add chelating agent or surfactant to stabilize the solution, and the added surfactant mostly adopts single anion, cation or nonionic surfactant. Because the amino acid is an amphoteric compound, the single anionic and cationic surfactants are easy to inactivate after contacting with the amino acid, and the problems of flocculation, precipitation, crystallization, layering and the like are easy to generate after inactivation, so that the effect of the surfactants cannot be exerted. And the commonly used zwitterionic surfactants: betaine, amine oxide, imidazoline and the like, and the surfactants have different salt resistance and poor high-salt resistance, and are easy to generate flocculation, precipitation, crystallization, delamination and other problems with amino acid fertilizers. The alkyl glycoside surfactant is of a cyclic structure, the weather resistance is not good, the bond loss can be caused by long-term high-temperature action, the stability of a plurality of alcoholic hydroxyl groups is poor, the phenomena of layering and turbidity are easy to occur, meanwhile, saccharide substances are easy to generate Maillard reaction, and the color change of heat storage is easy to influence the appearance of the product, for example, the fertilizer composition disclosed in the publication No. CN111315712A, wherein the nonionic surfactant alkyl polyglucoside is adopted. Therefore, the common anionic, cationic and nonionic surfactants adopted in the high-fertilizer and high-salt water soluble fertilizer containing amino acid are easy to generate flocculation and precipitation, influence the fertilizer effect and influence the solution stability as the water soluble fertilizer.
The fertilizer synergistic composition disclosed in publication No. CN109776154A, its application and fertilizer comprise seaweed compound 20-40 parts; 10-15 parts of organic matters; 5-10 parts of trace elements; 20-30 parts of amino acid; 10-20 parts of silicon fertilizer; and 10-20 parts of carbon-octane complex agent; the organic matter comprises betaine, the technical scheme is mainly used as a fertilizer for synergism, the main effect is to improve soil, and the amino acid is used for promoting the absorption of crop roots, but the problem of stability of mixing between the amino acid and the fertilizer/pesticide is not solved. Publication No. CN113773136A discloses a long-acting multifunctional foliar fertilizer and a preparation method thereof, wherein the long-acting multifunctional foliar fertilizer comprises the following raw materials of polymethylene urea solution, urea, potassium nitrate, magnesium sulfate monohydrate, EDTA-Cu, EDTA-Fe, EDTA-Zn, boric acid, ammonium molybdate, mineral potassium fulvate, amino acid, organic acid, vitamin, propylhydroxycyclodextrin, brassinolide, sodium salicylate, betaine, organic acid titanium and surfactant. According to the technical scheme, a chelating agent EDTA, a surfactant and betaine are added, the betaine has the function of improving the permeability of substances so as to activate an enzyme system, the betaine added into the fertilizer is common betaine, and the problem that amino acid, a high-salt fertilizer and pesticide lose effectiveness after being mixed is still not solved. The publication No. CN103936500A discloses a fertilizer composition for improving stress resistance of field-planted pear trees, which contains amino acid and betaine. The publication No. CN110627561A discloses a microbial fertilizer synergistic preparation and a preparation method thereof, wherein the microbial fertilizer synergistic preparation comprises 40-50% of homopolymerized amino acid, 25-30% of free amino acid, 5-10% of betaine, 5-10% of trehalose, 1-5% of organic acid and 1-5% of an auxiliary agent. Publication No. CN108347920A discloses agricultural adjuvant compositions and methods of using such compositions, wherein nutrient elements, fatty acid (C1-C3) alkyl esters, and betaine surfactants are employed. Publication No. CN108976033A discloses a water-soluble fertilizer synergist and a preparation method thereof, wherein an amino acid concentrated solution and betaine are added, the betaine and the amino acid concentrated solution are mainly added externally, and the stability effect between the amino acid and the fertilizer is still not solved. The publication No. CN108863555A discloses a liquid foliar fertilizer synergist and a preparation method and application thereof, and the synergist comprises a certain proportion of gamma-polyglutamic acid, dodecyl betaine, polyacrylamide and water, wherein the dodecyl betaine has the effect of enhancing the extension of foliar fertilizer liquid drops on the leaf surface to influence the adhesion, thereby achieving the synergism.
In summary, in the existing fertilizer or synergist containing amino acid, betaine surfactant is also adopted, but the adopted betaine surfactant is mainly conventional betaine, the conventional betaine is amphoteric surfactant, the surfactant is not high-salt resistant, and amphoteric surfactants such as betaine and the like are cationic in acidic environment, and are easy to flocculate or precipitate with the amino acid fertilizer. Meanwhile, the technical problem to be solved is mainly used as an external additive, and the high permeability and wettability of the betaine are utilized to achieve synergy, but the problem of flocculation generated after the existing amino acid is mixed with high-salt fertilizer or pesticide is not fundamentally solved, so that a product with high salt resistance, thickening, wetting synergy, solubilization, wide applicable pH value range and strong universality is needed.

comparative examples are set up as follows:
in the above table, "- -" indicates the addition amount of 0.
1. Salt tolerance evaluation test:
formulation stability at varying salt content
The evaluation method comprises the following steps: according to the low-temperature stability of HG/T2467.2-2003, the heat storage stability of HG/T2467.2-2003 and the NY 1429-2010 amino acid-containing water-soluble fertilizer, the appearance of the preparation is inspected after a surfactant is selectively added, and the heat storage stability is inspected.
According to detection, the preparations obtained in examples 1-18 are clear and transparent in appearance, and clear and transparent in 14-day cold and hot storage results, and have no layering, no precipitation and no crystallization. The stabilizer has different carbon chain distributions, and the alkylamide polyoxyethylene polyoxypropylene betaine with different structural groups has good salt resistance.
The data obtained by example 3, examples 14-18 and comparative examples 1-30 are shown in Table 1:
TABLE 1 Heat storage stability of different stabilizers under different salt concentrations
Remarking: "- -" represents a product that could not be prepared under low salt conditions, and subsequent testing was not conducted
As can be seen from Table 1, in comparative examples 10 to 15 and comparative examples 19 to 21, in which conventional alkyl betaines and alkyl amide betaines were used, the stability of the amino acid solution was better in the case of low-concentration salts, while the solution stability was inferior with increasing salt concentration, and precipitation and delamination occurred, which was not favorable for practical use.
Comparative examples 16 to 18 and comparative examples 22 to 24, in which a common alkyl polyoxyethylene-based surfactant was used, were less stable against amino acid solutions at different salt concentrations.
In comparative examples 7 to 9 and comparative examples 25 to 27, which use a common anionic surfactant and a common nonionic surfactant, it can be seen from the above data that the stability of the common single anionic surfactant and the single nonionic surfactant to an amino acid solution is poor.
As can be seen from the above examples and comparative examples, the invention adopts different carbon chain distributions, and the alkylamide polyoxyethylene polyoxypropylene betaine with different structural groups has good salt tolerance and good applicability, better salt tolerance than the conventional nonionic and zwitterionic surfactants, and more obvious solubilization effect on amino acid; the amino acid solution can maintain good stability under the conditions of high-concentration salt and low-concentration salt.
2. And (3) evaluating the applicability: pH value
