Embodiment 1

[0022] Phosphogypsum to make rapeseed growth promoter:

[0023] 1. Dry the waste phosphogypsum from the chemical plant, and then crush it to 200-400 mesh for later use; crush zinc sulfate, manganese sulfate, copper sulfate, humic acid, and borax separately for later use;

[0024] 2. Mix the above-mentioned phosphogypsum powder with pretreated zinc sulfate, copper sulfate, manganese sulfate, humic acid, and borax in a weight ratio to prepare a mixture; the mixing weight ratio is: phosphogypsum: zinc sulfate: copper sulfate: manganese sulfate : Borax: humic acid = 1000: 2-8: 0.3-3: 0.5-5: 1-10: 0.5-8; pass 200-400 mesh;

[0025] 3. Mix the above mixture thoroughly to form the final product;

Embodiment 2

[0027] Use of phosphogypsum as a special growth promoter for rapeseed:

[0028] 1. Dry the waste phosphogypsum from the chemical plant, and then crush it to 200-400 mesh for later use; crush the dried zinc sulfate, manganese sulfate, copper sulfate, humic acid, and borax separately for later use;

[0029] 2. Mix 1000kg of phosphogypsum powder with pretreated 3kg of zinc sulfate, 2kg of copper sulfate, 3kg of manganese sulfate, 5kg of borax, and 5kg of humic acid, and pass through 200-400 meshes;

[0030] 3. The above mixture is thoroughly mixed to obtain 1018kg of the final product.

Abstract

The invention relates to a phosphogypsum-contained rape growth promoting agent which comprises phosphogypsum, zinc sulfate, copper sulfate, manganese sulfate, humic acid and borax according to the proportion by weight of 1000:(2-8):(0.3-3):(0.5-5):(1-10):(0.5-8). A method for preparing the phosphogypsum-contained rape growth promoting agent comprises the following steps of: pulverizing the dry waste residue phosphogypsum, the zinc sulfate, the copper sulfate, the manganese sulfate, the humic acid and the borax to be 200-400 meshes for later use; mixing the phosphogypsum powder with the pulverized zinc sulfate, the pulverized copper sulfate, the pulverized manganese sulfate, the pulverized humic acid and the pulverized borax according to the proportion by weight to obtain a mixture, i.e. the rape growth promoting agent. The invention aims to solve the problem of environment pollution of the phosphorus chemical waste phosphogypsum, carries out the resource regeneration and utilization of environmental pollutants and provides a special phosphogypsum-contained rape growth promoting agent, the resource regeneration and utilization of the phosphorus chemical waste phosphogypsum is carried out by the special growth promoting agent through industrialized production, the required fertilizer of agricultural production is provided, the soil productivity can be improved and enhanced, the rape growth can be promoted, and the rape quality is improved.

Description

1. Technical field [0001] The invention relates to the field of agricultural technology, in particular to a special growth accelerator for producing rapeseed by resource utilization of phosphorus chemical industry waste and its preparation method and application. 2. Background technology [0002] The process of wet production of phosphoric acid and phosphate fertilizer produces a large amount of solid waste - phosphogypsum. The world produces about 100-280 million tons of scale gypsum every year. It is usually piled on the ground without any treatment, occupying and wasting a lot of land resources, and causing serious problems. environmental pollution. There are more than 400 phosphate fertilizer enterprises in my country, which produce 30-50 million tons of phosphogypsum waste residue every year. These waste residues are often untreated and piled on the ground, which not only occupies a large amount of land, but also contains a variety of heavy metal elements and has a low ...
