Abstract

The invention discloses an amino acid water-soluble fertilizer containing chitosan oligosaccharide. The amino acid water-soluble fertilizer is prepared from the following raw materials in parts by weight: 38 to 40 parts of pure water, 0.5 to 1 part of N-acetylthioproline, 2 to 3 parts of glycine, 1 to 4 parts of sorbitol, 17 to 20 parts of calcium nitrate tetrahydrate, 1 to 2 parts of magnesium nitrate hexahydrate, 28 to 30 parts of compound amino acid powder, 5 parts of chitosan oligosaccharide, 0.1 to 0.5 part of thickening agent and 1 to 3 parts of pH regulator. The preparation method of the water-soluble fertilizer comprises the following steps: 1) adding pure water into a reaction kettle, starting a stirrer, adding N-acetylthioproline, glycine and sorbitol, and stirring until the N-acetylthioproline, glycine and sorbitol are completely dissolved; 2) adding calcium nitrate tetrahydrate and magnesium nitrate hexahydrate, and stirring until the materials are completely dissolved; (3) adding compound amino acid powder and chitooligosaccharide, and stirring until the materials are completely dissolved, (4) adding the thickening agent, and stirring until the materials are completely dissolved, and (5) standing to normal temperature, adding the pH regulator to adjust the pH value to 5.0-7.0, and carrying out spot check to obtain the product. The water-soluble fertilizer prepared by the method contains 5% of chitooligosaccharide, is stable in character and remarkable in fertilizer efficiency, and can be mixed with a part of the suspending agent for use.

Description

technical field [0001] The invention relates to the field of liquid fertilizers, more specifically, to an amino acid water-soluble fertilizer containing chitooligosaccharides and a preparation method thereof. Background technique [0002] The research on liquid fertilizers started relatively late in my country. The initial products of liquid fertilizers are mostly simple fertilizers such as ammonia water, urea ammonium nitrate liquid, nitric acid, and phosphoric acid. These fertilizers are mostly simple fertilizers, and most of them are strong acid and strong alkaline fertilizers. Extremely inconvenient. With the improvement of technology, many functional fertilizers have appeared on the market. Their function is to increase amino acid and humic acid on the basis of common large, medium and trace element fertilizers such as nitrogen, phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, copper, and molybdenum. , alginic acid and other biostimulant components, the...
