Abstract

The invention discloses an amino acid calcium water-soluble fertilizer and a preparation method thereof. The fertilizer is a liquid fertilizer obtained by chelation with amino acid in the presence of a calcium-containing compound, a boron-calcium-containing compound, EDTA (Ethylene Diamine Tetraacetic Acid), a surfactant and an adjuvant, wherein amino acid is not less than 100 g/L, calcium is not less than 30 g/L, boron is not less than 2.5 g/L, and the mass ratio of EDTA is 2%-4%. By use of the amino acid calcium and boron chelated fertilizer, the fruit expansion can be promoted, the weight of a single fruit is increased, bitter pit, navel rot and black spot diseases caused by calcium and boron deficiency are reduced or treated, thus the yield of fruit is increased, the fruit quality is improved and the economic benefit is obviously improved.

Description

Technical field [0001] The invention belongs to the technical field of agricultural compound calcium fertilizers, and relates to an amino acid calcium water-soluble fertilizer and a preparation method thereof. Background technique [0002] Calcium exists in the form of calcium pectate in crops and is a component of the glue layer in the cell wall. The combination of calcium and protein is an important part of the cell plasma membrane. It plays an important role in the formation of cell membranes and reduces the permeability of cell membranes, restricts the extravasation of cell fluids and regulates its pH. Calcium can also promote nitrogen metabolism and carbohydrate conversion, reduce nitrate in plants, neutralize organic acids in plants, and detoxify organic acids produced during metabolism. [0003] Calcium in plants is transported in the form of calcium ions through the xylem together with water to the leaves, fruits, shoots and other organs, and then passes through the cells ...
