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

Abstract

The invention discloses a formula and method for making a compound fertilizer from sodium polyacrylate and sodium humate. The preparation method comprises the steps of: a. crushing a raw material porphyritic monzonitic granite or medical stone into particles able to pass a 120-mesh sieve for standby use; b. crushing calcium magnesium phosphate fertilizer, sodium humate and humic acid, urea, sodium polyacrylate, polyaspartic acid, and rare earth nitrate respectively into particles able to pass a 80-mesh sieve for standby use; and c. putting the raw materials crushed in step a and the raw materials crushed in step b into a stirrer according to a weight ratio and stirring the materials evenly, and then performing granulation according to a conventional method to make a compound calcium magnesium phosphate fertilizer.

Description

technical field [0001] The invention relates to a boron fertilizer, in particular to a formula and a method for making compound fertilizer by using sodium polyacrylate and sodium humate as raw materials, 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 "a...
