Embodiment 1

[0041] (1) Add the corn stalk powder passed through a 100-mesh sieve into pig manure to adjust the water content to 12.5%, then add ethanol, the amount of sodium cetylsulfonate is 7.5‰ of the mixed material, and the amount of ethanol 7.5% of the mixed material, stir evenly, then add the mixed material into the steam explosion tank and feed steam at a speed of 70mL / min, adjust the pressure in the steam explosion tank to 4.6MPa, keep the pressure for 12min, and then open the steam explosion tank instantly The bottom valve is used for steam explosion, and the material is discharged to obtain feces after steam explosion;

[0042] (2) Add 150kg of feces after steam explosion into the horizontal decomposing tank, then add 0.2kg of Bacillus subtilis, then adjust the water content of the feces by spraying the decomposing filtrate, and at the same time, feed oxygen to maintain the oxygen content, and then turn on the stirring rod to turn over For feces, the stirring rod of the horizont...

Embodiment 2

[0046] (1) Add rice straw powder passed through a 100-mesh sieve into cow dung to adjust the water content to 11%, and then add ethanol. The amount of polyoxyethylene fatty alcohol ether added is 6‰ of the mixed material, and the amount of ethanol added is 6% of the mixed material, stir evenly, then add the mixed material into the steam explosion tank and introduce steam at a speed of 65mL / min, adjust the pressure inside the steam explosion tank to 4.5MPa, keep the pressure for 14min, and then open the bottom of the steam explosion tank instantly The valve is used for steam explosion, and the material is discharged to obtain feces after steam explosion;

[0047] (2) Add 120kg of steam-exploded feces into the horizontal decomposing tank, then add 0.25kg of Bacillus megaterium, then adjust the water content of the feces by spraying the decomposing filtrate, while feeding oxygen to maintain the oxygen content, and then turn on the stirring rod to turn over For feces, the stirring...

Embodiment 3

[0051] (1) Add the sorghum stalk powder passed through a 100-mesh sieve into the chicken manure to adjust the water content to 14%, then add sodium cetyl sulfonate and ethanol, the amount of sodium cetyl sulfonate is 9‰, the amount of ethanol added is 9% of the mixed material, stir evenly, then add the mixed material into the steam explosion tank and feed steam at a speed of 75mL / min, adjust the pressure in the steam explosion tank to 4.8MPa, and keep the pressure for 11min , and then instantly open the bottom valve of the steam explosion tank, carry out steam explosion, discharge the material, and obtain feces after steam explosion;

[0052] (2) Add 180kg of feces after steam explosion into the horizontal decomposing tank, then add 0.15kg of Bacillus subtilis, then adjust the water content of the feces by spraying the decomposing filtrate, and at the same time feed oxygen to maintain the oxygen content, and then turn on the stirring rod to turn over For feces, the stirring ro...

Abstract

The invention provides a method for efficiently producing an organic fertilizer. The method comprises the following steps of: uniformly mixing straw powder, a penetrating agent, ethanol and excrementand then carrying out steam explosion to obtain steam-exploded excrement; adding microbial strains, and introducing oxygen to decompose the steam-exploded excrement; centrifugally separating the obtained decomposed excrement; adjusting the water content of the decomposed excrement by using decomposed filtrate; and mixing and aggregating the solid decomposed excrement with the microbial strains, anutritional agent, auxiliary materials and a binder to obtain the granular organic fertilizer. According to the method provided by the invention, by utilizing steam explosion, the decomposition efficiency of the materials is greatly improved, and the production period of the organic fertilizer is shortened; meanwhile, in the decomposition process, the activity of aerobic bacteria is improved through constant temperature, oxygen introduction and decomposition filtrate spraying; and meanwhile, excrement is loosened by slowly turning over the excrement, and contact between the excrement and oxygen is increased, so that decomposition of the excrement is accelerated, the production period of the organic fertilizer is shortened, and the production efficiency of the organic fertilizer is improved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a method for efficiently producing organic fertilizers. Background technique [0002] Organic fertilizers are carbon-containing materials mainly derived from plants and (or) animals, and applied to the soil to provide plant nutrition as its main function. It is processed from biomass, animal and plant waste, and plant residues to eliminate toxic and harmful substances, and is rich in a large number of beneficial substances, including: a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. nutritional elements. Organic fertilizer can not only provide comprehensive nutrition for crops, but also has a long fertilizer effect. It can increase and renew soil organic matter, promote microbial reproduction, improve soil physical and chemical properties and biological activity, and is the main nutrient for green food produ...
