Embodiment 2 10

[0035] The use effect of embodiment 2 zinc decaborate sodium salt on rice

[0036] Both boron and zinc are essential trace elements for crops, so sodium zinc decaborate monohydrate of the present invention can be applied to all crops on boron-deficient and zinc-deficient soils. Applying this product on boron-deficient and zinc-deficient soils can quickly correct crop defects. To ensure the stable and high yield of crops, and the quality of agricultural products has been significantly improved. Due to the excellent characteristics of this product, the pH is moderate, there is no pollution to the soil and the environment, no harm to the ecological environment, and it has good ecological benefits.

[0037] 1. Source and purpose of the test

[0038] Sodium zinc decaborate is produced by Anhui Nongwang Agricultural Science and Technology Development Co., Ltd. In order to verify the application effect of the product on rice, choose a reasonable application period and application r...

Abstract

The invention provides a compound monohydrate sodium zinc decaborate Na2Zn2B10O18.H2O and a preparation method therefor. Sodium decaborate and zinc sulfate or zinc chloride are reacted at high temperature under high pressure to produce water liquid products. The crystals are subjected to fluid bed drying or spray drying to form powder products. The compound can be hydrolyzed fully, the dissolving speed is rapid, the compound is of great significance to be used for agricultural production and especially used for crops needing more boron and zinc, and the yield increases by 20-30%.

Description

technical field [0001] The invention relates to a zinc sodium borate fertilizer, more specifically, it relates to a preparation method of an instant zinc borate sodium borate fertilizer containing zinc sodium decaborate. Background technique [0002] Since the 1990s, the trace element fertilizers boron, zinc, iron and molybdenum in my country's chemical fertilizer industry have been vigorously promoted in agricultural production, which has effectively promoted the development of my country's agricultural production, especially the popularization of boron and zinc elements. Larger area. [0003] Zinc is very important in the vegetative growth of crops. Zinc mainly constitutes enzymes. Zinc acts as a bridge between the enzyme and the substrate. Zinc-containing compound enzymes are distributed in six categories, including oxidoreductases, transferases, hydrolases, lyases, isomerases and synthetases, and there are 59 species. Zinc can also activate oxaloacetate oxidase, enola...
