Medium element water-soluble fertilizer for improving apple quality and coloring and preparation method thereof

Abstract

A medium-element water-soluble fertilizer for improving apple quality and promoting coloring belongs to the field of functional water-soluble fertilizers. , 30%‑40% beet molasses, 0.4%‑1% sodium octaborate, 0.4%‑1% zinc nitrate hexahydrate, 0.1%‑0.3% vitamin B2, 1%‑2% sodium glutamate, 2%‑3 % yeast extract, 1%-2% sodium diisooctyl maleate sulfonate and water balance; the preparation process includes yeast extract, sodium glutamate, zinc nitrate hexahydrate, sodium octaborate, Mixing reaction with water to prepare material I, and then mix calcium nitrate tetrahydrate, magnesium nitrate hexahydrate, beet molasses, vitamin B2, and sodium diisooctyl maleate sulfonate to obtain material II, and mix materials I and II. , the product is obtained; the fertilizer of the invention can improve the coloring degree, sugar content, sugar-acid ratio and Vc content of apples.

Description

technical field [0001] The invention belongs to the field of functional water-soluble fertilizers, relates to a medium-element water-soluble fertilizer, and in particular relates to a medium-element water-soluble fertilizer for improving apple quality and promoting coloring, and a method for using the same. Background technique [0002] Apple quality and coloration are one of the most important commodity factors, which determine the market price of apples. The improvement of apple quality and coloring degree has become an important measure to ensure the increase of production and income of fruit farmers. The existing improvement measures include: (1) Increase the application of potassium fertilizer, the sugar content of apples increases, but the incidence of bitter pox is generally also increased accordingly, the fruit is not resistant to storage and transportation, and the commodity is reduced. (2) Increasing the application of potassium and calcium fertilizers reduced the...

AI Technical Summary

Problems solved by technology

The existing improvement measures include: (1) Increase the application of potassium fertilizer, the sugar content of apples increases, but the incidence of bitter pit disease generally increases accordingly, the fruit is not resistant to storage and transportation, and the commerciality decreases

(2) Increase the application of potassium and calcium fertilizers to reduce the incidence of bitter pit disease, but the color change of apples is delayed and the glossiness is reduced. In the end, it is difficult to change the color well, even if various color change nutrient solutions are sprayed, it is difficult to make up for it

(3) Spraying 5-aminolevulinic acid, abscisic acid and other plant growth regulators during the apple color change period can improve the apple coloring degree, but the use concentration is strict, too high will easily lead to the occurrence of sunburn and reduce the fruit commodity sex
