Embodiment 1

[0010] Example 1 The organic selenium-enriched biological fertilizer uses 300 kilograms of chicken manure, 400 kilograms of straw powder with a moisture content of less than 10%, 250 kilograms of 80-mesh selenium mineral powder containing 500 ppm selenium, and 5 kilograms of microbial soil restoration agent produced by Beijing New Era Sanse Ecological Technology Co., Ltd. and 2 kg of fermented bacteria. Mix livestock and poultry manure, straw powder or humus soil, selenium mineral powder containing 500ppm 80 mesh, microbial soil repair agent, fermentation bacteria, fully stir and evenly pile up and ferment. After reaching 65°C, mycelium appears and the pile is turned over for about eight days, and finally piled up and fermented for about three days to facilitate anaerobic humification of the fertilizer. The fertilizer can be put into storage after being crushed, screened and packaged.

Embodiment 2

[0011] Example 2 The organic selenium-enriched biological fertilizer uses 650 kg of fresh chicken manure, 150 kg of humic acid soil, 50 kg of straw powder, 150 kg of 80-mesh selenium mineral powder containing 500 ppm selenium, and a microbial soil restoration agent produced by Beijing New Era Sanse Ecological Technology Co., Ltd. 5 kg and 2 kg of fermented bacteria. Stir livestock and poultry manure, straw powder or humus soil, selenium mineral powder, microbial soil repair agent, and fermented bacteria fully and evenly to pile up and ferment. When the temperature reaches 40°C, turn the pile and turn it once every two days. When the temperature reaches 65°C, it will appear After the mycelia, turn the pile for about eight days, and pile up and ferment for about three days to facilitate anaerobic humification of the fertilizer. The fertilizer can be put into storage after being crushed, screened and packaged.

Embodiment 3

[0012] Embodiment 3 The organic selenium-enriched biological fertilizer uses 650 kilograms of chicken manure with a water content of 75%, 200 kilograms of straw powder, 150 kilograms of selenium mineral powder containing 500 ppm of selenium, 5 kilograms of microbial soil restoration agents produced by Beijing New Era Sanse Ecological Technology Co., Ltd. and 2 kg of fermented bacteria. Mix livestock and poultry manure, straw powder or humus soil, selenium mineral powder containing 500ppm 80 mesh, microbial soil repair agent, fermentation bacteria, fully stir and evenly pile up and ferment. After reaching 65°C and mycelia appear, turn the pile for about eight days, and pile up and ferment for about three days to facilitate anaerobic humification of the fertilizer. After the fermentation, the selenium mineral bio-organic fertilizer enters the pulverizer for pulverization. The crushed organic fertilizer is screened in a sieving machine, dried and granulated, and the granulated g...

Abstract

The invention relates to an organic rich-selenium bio-fertilizer and a preparation method thereof. The organic rich-selenium bio-fertilizer comprises the following components in percentage by weight: 10-40% of livestock / poultry excrement, 20-50% of straw powder or humus soil, 20-40% of 80-mesh selenium ore powder containing 500 ppm of selenium, 0.02-0.07% of microbial soil repairing agent and 0.01-0.03% of zymocyte. The preparation method comprises the following steps: thoroughly and uniformly stirring the raw materials and stacking for fermentation; when the temperature reaches 40 DEG C, starting to turn the pile once every two days; when the temperature reaches 65 DEG C and hyphae appear, turning the pile; stacking for fermentation for three days; and crushing, screening, packing and storing the product in a storehouse. The method provided by the invention mainly thoroughly decomposes the raw materials containing various nutrients at a high temperature under the effect of microorganisms, converts inorganic selenium into an organic selenium fertilizer for the absorption by plants and animals, and produces rich-selenium organic products.

Description

technical field [0001] The invention belongs to the technical field of organic biological fertilizers, and in particular relates to an organic selenium-enriched biological fertilizer and a preparation method thereof. Background technique [0002] As a new type of fertilizer, bio-organic fertilizer, after being applied to the soil, can fully utilize the nutrient potential of the environment through the rapid reproduction of its specific strains, and create a good soil microbial environment for crop growth. It is of great significance to reduce pollution and improve the quality of crops. It is very common to use selenium-containing fertilizers in selenium-deficient areas. At present, there is no product produced by mixing selenium ore powder and bio-organic fertilizers. Contents of the invention [0003] The object of the present invention is to provide an organic selenium-enriched biological fertilizer and a preparation method thereof. [0004] An organic selenium-enriche...
