Problems solved by technology

[0002] Fertilizer is an indispensable nutrient for agricultural production and plant absorption. Plants need to absorb various nutrients. Among them, boron fertilizer is one of the nutrients needed by plants. Currently, boron fertilizers on the market are mainly borax, boric acid and boron mud. It is solid, and its solubility and plant absorption ability are not satisfactory. Farmers spend money and have little effect. In addition, more than 95% of the soil in China is deficient in soluble boron. Boron fertilizer floods the market and harms farmers

Embodiment Construction

[0006] The present invention will be further described below in conjunction with specific examples.

[0007] A kind of method adopting boric acid and borax to make crop boron fertilizer, its method is: (1) fully mix 60 kilograms of boric acid and 40 kilograms of borax; Heated for 1 hour and dehydrated to obtain boric anhydride and anhydrous borax mixture; (3) the boric anhydride and anhydrous borax mixture placed in a common dry oven were naturally cooled; (4) boric anhydride and anhydrous borax mixture were cooled to Take it out after 40°C-60°C, grind it with a high-speed grinder or jet grinder at 3000 rpm, and sieve it with a 100-150 mesh screen to obtain a boron fertilizer with a pure boron content of 26%.

Abstract

The invention discloses a method for producing a crops boron fertilizer by employing boric acid and borax. The method comprises the followings steps: 1) fully mixing 60 kilograms of boric acid and 40 kilograms of borax; 2) placing a mixture in a common hot air oven, heating the mixture for 1 hour at the temperature of 400-450 DEG C for dehydration to obtain a mixture of boric anhydride and anhydrous borax; 3) naturally cooling the mixture of boric anhydride and anhydrous borax placed in the common hot air oven; and 4) cooling the mixture of boric anhydride and anhydrous borax to the temperature of 40-60 DEG C, and then taking the mixture out, employing a high-speed pulverizer or an air-flow pulverizer for crushing the mixture with a speed of 3000 R / min, and employing a 100-150-mesh screen mesh for sieving the mixture to obtain the boron fertilizer having pure boron content being 26%.

Description

technical field [0001] The invention relates to a boron fertilizer, in particular to a method for producing boron fertilizer for crops by using boric acid and borax, and belongs to the technical field of agricultural chemical fertilizers. Background technique [0002] Fertilizer is an indispensable nutrient for agricultural production and plant absorption. Plants need to absorb various nutrients. Among them, boron fertilizer is one of the nutrients needed by plants. Currently, boron fertilizers on the market are mainly borax, boric acid and boron mud. It is solid, and its solubility and plant absorption ability are not satisfactory. Farmers spend money and have little effect. In addition, more than 95% of the soil in China is deficient in soluble boron. Boron fertilizer floods the market and harms farmers. How to solve the contradiction between supply and demand in the market, protect the interests of farmers from infringement, serve "agriculture, rural areas and farmers" a...
