Problems solved by technology

[0004] The development of medium and trace element fertilizers in my country has gone through three main stages. The first stage is poorly water-soluble inorganic sulfates and oxides, hydroxides, borax, boric acid, etc., and the application effect is poor.
The second stage is calcium nitrate, calcium chloride, polyborate, etc. with good water solubility. The application effect is average, the absorption efficiency is low, the mobility in the plant is poor, and the internal quality of the crop is not significantly improved.
However, the calcium-boron foliar fertilizers provided on the market are basically single-element fertilizers, which contain only calcium or boron, and are expensive, which cannot effectively meet the urgent needs of the majority of growers.

Abstract

The invention discloses a calcium and boron clear liquid fertilizer for improving economic crops in a salt-alkaline land and a preparation method thereof. The calcium and boron clear liquid fertilizerfor improving the economic crops in the salt-alkaline land is mainly prepared by chelating raw materials of a sugar alcohol compound, a calcium-containing compound, a boron-containing compound, and biological active matters, wherein the content of sugar alcohol compound is greater than or equal to 100g / l; the content of calcium is greater than or equal to 150g / l; the content of boron is greater than or equal to 20g / l. The calcium and boron clear liquid fertilizer has the advantages that the content is high, the quality stability and application effect are good, the calcium and boron are mutually promoted to absorb, the utilization rate of nutrients is high, and the enough calcium and boron nutritional components are provided for the crops; the swelling of fruits is promoted, the physiological diseases of bitter pit, blossom-end rot and the like due to lack of calcium and boron can be reduced or prevented and controlled, the fruit quality is improved, the output is increased, and the economic benefit is improved.

Description

technical field [0001] The invention relates to the fields of agricultural biotechnology and fertilizers, in particular to a calcium-boron clear liquid fertilizer for improving economic crops in saline-alkaline areas and a preparation method thereof. Background technique [0002] During the growth of crops, calcium exists in the form of calcium pectate in crops, which is a component of the glue layer in the cell wall. Calcium and boron play an important role in the formation of fruit yield and the improvement of fruit quality. . 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, neutralize organic acids in plants, and have a detoxification effect on organic acids produced dur...
