Embodiment 1

[0023] The biochar used in the experiment came from the cut root of Flammulina velutipes. Cut root stock was dried in an oven at 55 °C to constant weight. Weigh 30-50 g of dry raw materials, place them in a tube furnace, and set the carbonization temperature at 300°C. Before heating up, use an air pump to evacuate the entire pipeline into a vacuum (-0.5MPa), and then pass helium until the gas outlet reaches (+0.02MPa). At this time, the pyrolysis atmosphere in the furnace is high-purity helium. The heating rate is 10~15℃min -1 , keep warm for 2h, cool to room temperature and take out. The solid product is root-cut charcoal and stored in a desiccator at 300°C until use.

The solid product is root-cut charcoal at 500°C, and it is stored in a desiccator until use.

Embodiment 3

[0027] The biochar used in the experiment was derived from Flammulina velutipes mushroom residue. Cut root stock was dried in an oven at 55 °C to constant weight. Weigh 30-50 g of dry raw materials, place them in a tube furnace, and set the carbonization temperature at 300°C. Before heating up, use an air pump to evacuate the entire pipeline into a vacuum (-0.5MPa), and then pass helium until the gas outlet reaches (+0.02MPa). At this time, the pyrolysis atmosphere in the furnace is high-purity helium. The heating rate is 10~15℃min -1 , keep warm for 2h, cool to room temperature and take out. The solid product is mushroom residue charcoal, and it is stored in a desiccator at 300°C until use.

Abstract

The invention discloses a method for treating flammulina velutipes cultivation waste and a product and application thereof, and relates to the technical field of biological agriculture. The method comprises the following steps: drying the flammulina velutipes cultivation waste, and carbonizing and pyrolyzing the flammulina velutipes cultivation waste in an inert gas atmosphere to obtain biochar; the flammulina velutipes cultivation waste is flammulina velutipes cut roots or flammulina velutipes residues. Compared with a traditional treatment method, the method for treating the flammulina velutipes cultivation waste has the advantages that resource waste can be reduced, environmental pollution can be reduced, and the additional value of agricultural production can be increased; the biochar prepared by the method disclosed by the invention is high in stability and carbon content, has positive significance on'carbon neutralization 'when being applied to farmland, and has great contribution to carbon reserve in soil after entering the soil.

Description

technical field [0001] The invention relates to the technical field of bio-agriculture, in particular to a method for treating cultivation waste of Flammulina velutipes and its product and application. Background technique [0002] Flammulina velutipes has another name called winter mushrooms, mushrooms, belongs to Basidiomycetes, Agaricaceae, and its fruiting bodies are slender and clustered like golden needles, so they are called Flammulina velutipes. The stipe of the fruiting body of Flammulina velutipes is slender, with a diameter of 0.3 to 1.5 cm and a length of 3.5 to 15.0 cm. Flammulina velutipes is rich in nutrition and delicious in taste, and is a kind of edible fungus that people like. The output of Flammulina velutipes ranks fifth in the global edible fungi industry. In 2019, the total industrial production of Flammulina velutipes in my country was 1.638 million tons. [0003] The root of Flammulina velutipes is a section of 3-5 cm long in the lower part of the...
