Problems solved by technology

For a large number of edible fungus residues, if not handled properly, it will not only pollute the environment, but also be a waste of resources
[0003] At present, the treatment methods of edible fungus residues mainly include discarding, incineration, and processing into feed or fertilizer. Mushroom residues are rich in protein and other nutrients. Random discarding is a waste of resources, and it is easy to cause the growth of mold and pests. , causing environmental pollution; and incineration can only obtain about 10% of the energy, which is an unreasonable use of biomass; the fungus residue is very safe as a raw material for feed preparation, but its role has not been fully recognized by consumers and acceptance, so the market has certain restrictions; it takes a long time for the fungus residue to be used for composting

Abstract

The invention discloses a mushroom residue carbon-based microbial organic fertilizer preparation method, which comprises: drying and crushing mushroom residue, uniformly mixing with a sodium bicarbonate solution, standing for 30-40 min, filtering, and taking mushroom residue; uniformly mixing and stirring the obtained mushroom residues with a proper amount of mesoporous silica nanoparticles, and performing pyrolysis for 0.5-1 hour at 500-550 DEG C under the protection of nitrogen to obtain a mushroom residue carbon base; inoculating the compound microbial agent into a liquid culture medium, culturing and activating, and activating at 25-30 DEG C to form a microbial agent; a proper amount of molasses, a proper amount of the microbial agent and a proper amount of the mushroom residue carbon base are taken and mixed in proportion, the volume is fixed to 1 L with clear water, the mixture is placed for 24 h at the temperature of 30 DEG C, and the mushroom residue carbon base microbial organic fertilizer is formed. The mushroom residue carbon base obtained by the invention has the characteristics of developed pore size, uniform pore size distribution, large specific surface area and strong adsorption and chelation capabilities, and a new method is provided for treatment of edible mushroom residues.

Description

technical field [0001] The invention relates to the field of fertilizer preparation, in particular to a preparation method of a mushroom residue carbon-based microbial organic fertilizer. Background technique [0002] my country is a big producer of edible mushrooms. In recent years, with the development of edible mushroom production, the output of edible mushroom residues in the country is huge. For a large number of edible mushroom residues, if not handled properly, it will not only pollute the environment, but also a waste of resources. [0003] At present, the disposal methods of edible fungus residues mainly include discarding, incineration, and processing into feed or fertilizer. The residues are rich in protein and other nutrients. Discarding them at will is a waste of resources and easily leads to the growth of molds and pests. , causing environmental pollution; and incineration can only obtain about 10% of the energy, which is an unreasonable utilization of biomass...
