Embodiment 1

[0017] Coal gangue with a selenium content of 200-250 mg / kg produced in Enshi, Hubei, medical stone and Muyu stone with selenium produced in Tai'an, Shandong were respectively selected, pulverized, and ball-milled into coal gangue powdery raw materials with a particle size of 60-80 meshes, wheat Rice stone powdery raw material and Muyu stone powdery raw material; Then get 15 kilograms of coal gangue powdery raw material, 10 kilograms of medical stone powdery raw material and 10 kilograms of Muyushi powdery raw material and mix homogeneous mineral raw material; Add 0.8 kg of acetic acid solution with a concentration of 12 mg / L to the raw material and stir and mix evenly to form an acidified mineral raw material. Then, the above-mentioned acidified mineral raw material is mixed with 65 kg of poultry manure and fermented evenly, and a selenium-enriched organic fertilizer product is obtained after 30-60 days of fermentation and maturity.

Embodiment 2

[0019] Coal gangue with a selenium content of 200-250 mg / kg produced in Enshi, Hubei, medical stone and Muyu stone with selenium produced in Tai'an, Shandong were respectively selected, pulverized, and ball-milled into coal gangue powdery raw materials with a particle size of 60-80 meshes, wheat Rice stone powdery raw material and wood fish stone powdery raw material; Then get 20 kilograms of coal gangue powdery raw materials, 6 kilograms of medical stone powdery raw materials and 20 kilograms of wooden fish stone powdery raw materials and mix homogeneous mineral raw materials; Add 0.7 kg of acetic acid solution with a concentration of 15 mg / L to the raw material and stir and mix evenly to form an acidified mineral raw material. Then, the above-mentioned acidified mineral raw material is mixed with 54 kg of poultry manure to carry out fermentation, and after 30-60 days of fermentation and maturity, a selenium-enriched organic fertilizer product is obtained.

Embodiment 3

[0021] Coal gangue with a selenium content of 200-250 mg / kg produced in Enshi, Hubei, medical stone and Muyu stone with selenium produced in Tai'an, Shandong were respectively selected, pulverized, and ball-milled into coal gangue powdery raw materials with a particle size of 60-80 meshes, wheat Rice stone powdery raw material and wood fish stone powdery raw material; Then get 10 kilograms of coal gangue powdery raw materials, 16 kilograms of medical stone powdery raw materials and 5 kilograms of wooden fish stone powdery raw materials and mix homogeneous mineral raw materials; Add 0.6 kg of acetic acid solution with a concentration of 10 mg / L to the raw material and stir and mix evenly to form an acidified mineral raw material. Then, the above-mentioned acidified mineral raw material is mixed with 70 kg of poultry manure to ferment evenly, and a selenium-enriched organic fertilizer product is obtained after 30-60 days of fermentation and maturity.

Abstract

The invention relates to a method for producing a selenium-enriched organic fertilizer. The method comprises the following steps: respectively crushing selenium-containing gangue, selenium-containing medical stone and limonit, and ball milling into powdery raw material; then, mixing into mineral raw material in proportion, adding acetate to mix into acidified mineral raw material; finally, mixing the acidified mineral material and the biological organic fertilizer to ferment, and obtaining selenium-enriched organic fertilizer after well fermentation. The selenium-enriched organic fertilizer prepared by the method can prevent soil pollution, improve the soil structure and quality, and has adsorption and conversion functions on the heavy metal in the soil. The selenium-enriched organic fertilizer prepared by the method is a functional agricultural product. After people eat the functional agricultural product, the immunity of the human body can be adjusted, the physical health can be strengthened, and the effects of disease prevention, cancer prevention and cancer resistance can be achieved.

Description

technical field [0001] The invention relates to a method for manufacturing fertilizer, in particular to a method for manufacturing selenium-enriched organic fertilizer. Background technique [0002] Chemical fertilizers have been used in my country for more than half a century, and have made great contributions to reducing the labor intensity of farmers and increasing crop yields. However, the long-term use of chemical fertilizers has also produced many problems. First, it pollutes the environment, which causes serious harm to human health; secondly, chemical fertilizers often only contain a single fertilizer element, and long-term use will affect the nutritional structure of the soil. Produce damage, and then affect the poor nutritional structure of crops; the third is that long-term use will damage the physical structure of the soil, resulting in soil compaction, which is not easy to cultivate. Therefore, in recent years, people have gradually resumed the use of organic f...
