Abstract

The invention discloses an amino acid calcium boron chelated foliar fertilizer and a preparation method thereof; the fertilizer is a liquid fertilizer prepared by chelating a calcium containing compound and a boron calcium containing compound with amino acids in the presence of EDTA, a surfactant and an additive, wherein, the amino acid is not less than 100 g/L; the calcium is not less than 30 g/L; the boron is not less than 2.5 g/L; and the mass ratio of EDTA is 2-4%. The application of the amino acid calcium boron chelated fertilizer can promote fruit expansion, increase single fruit weight, reduce or treat bitter pit diseases, blossom-end rot, and black red-dot diseases caused by calcium and boron deficiency, thus increase fruit yield, improve fruit quality, and significantly improve economic benefits.

Description

technical field [0001] The invention belongs to the technical field of agricultural compound calcium fertilizer, and relates to an amino acid calcium boron chelated foliage fertilizer and a preparation method thereof. Background technique [0002] Calcium exists in plants in the form of calcium pectate, which is a component of the glue layer in the cell wall. Calcium is combined with protein and is an important part of the plasma membrane of the cell. It plays an important role in the composition of the cell membrane and reduces the permeability of the cell membrane, restricts the extravasation of the cell fluid, and regulates its pH. Calcium can also promote nitrogen metabolism and carbohydrate conversion, reduce nitrate in plants, neutralize organic acids in plants, and have a detoxification effect on organic acids produced during metabolism. [0003] Calcium is transported in the form of calcium ions through xylem and water to leaves, fruits, shoots and other organs in p...
