Amino acid fertilizer capable of expanding crop bulbs and fruits and preparation method thereof

Abstract

The invention relates to an amino acid fertilizer capable of enlarging the corm and fruit of a crop and a method for preparing the amino acid fertilizer capable of enlarging the corm and fruit of the crop. The amino acid fertilizer is made by mixing the following materials: amino acid powder, a boron fertilizer, zinc sulfate monohydrate, a potassium fertilizer, citric acid, molybdenum sulfate, gibberellic acid, sodium alpha-naphthalene acetate, ethanol, a surfactant and water. The method for preparing the amino acid fertilizer comprises the following steps: dissolving the amino acid powder in water, and then dissolving citric acid and molybdenum sulfate in the mixture to obtain a solution A; heating to dissolve the boron fertilizer and zinc sulfate monohydrate to obtain a solution B after the boron fertilizer and zinc sulfate monohydrate are added in the solution A; and dissolving gibberellic acid in ethanol, then completely dissolving 2-poly(naphthalene sulphonate formaldehyde) sodium salt, glycol butyl ether and sodium alpha-naphthalene acetate in the ethanol to obtain a solution C, mixing the solutions B and C and completely dissolving the potassium fertilizer in the mixture to obtain the amino acid fertilizer. The amino acid fertilizer capable of enlarging the corm and fruit of the crop disclosed by the invention provides a plurality of medium trace elements for the growth of crops; the amino acid powder can improve the physical and chemical properties, microbial community, tillage performances and nutrient status of soil; and the plant growth regulator, phosphorus and potassium fertilizer can promote the enlarging of the corm of crops and the enlarging and coloring of the fruit of fruit trees, and improve the quality as well as ripening control of the corm and fruit.

[0002] Fruit kohlrabi is a new species of biennial herb kohlrabi in the genus Brassica of Brassicaceae. Native to the Mediterranean coast, it is mutated from leafy cabbage. The root system is shallow, the stem is shortened, and the leaves are clustered on the shortened stem. The leaves are oblong, blue-green, smooth, and the petiole is slender. After growing to a certain extent, the stem expands to form an edible fleshy bulb. Every 100g of fruit kohlrabi contains 91-94g of water, 2.8-5.2g of carbohydrates, 1.4-2.1g of crude protein, 34-64mg of vitamin C, and the nutritional grade is A. The fruit kohlrabi is rich in vitamin C, which has a therapeutic effect on stomach problems, has the effect of relieving pain and promoting muscle growth, and can promote the healing of gastric and duodenal ulcers; the wa...
