Abstract

The invention relates to edible fungus residue biochar. The biochar is prepared from, by weight, 45-50 parts of edible fungus residues, 2-3 parts of acetic acid, 2-3 parts of an inoculating microorganism agent, 1-2 parts of urea, 8-10 parts of sodium bicarbonate, 5-8 parts of sodium hydroxide and 1-2 parts of calcium chloride. The biochar has the advantages that the porous diameter distribution isuniform, the absorbing performance is good, the quality stability is high, and the biochar can be recycled and is worthy of marketing popularization and use.

Description

technical field [0001] The invention relates to the treatment and utilization of organic solid waste of crops, in particular to a biochar of edible fungus residue and a preparation method thereof. Background technique [0002] At present, with the vigorous development of the edible fungi industry, a large amount of edible fungus residues are produced every year in my country. The compost mainly composed of wood chips, the remaining part after the edible fungi are cultivated and picked is the fungus residue (or fungus chaff). Because the fungus residue is closely connected together by the mycelium, the agglomeration or compaction is very deep, the hardness is high, and the water absorption of the fungus residue is poor, relatively light and dry, even if a crusher is used, it is not easy to break and disperse evenly, and its crushing The dust in the process is also large and the crushing effect is poor, which hinders the subsequent resource utilization of the fungus residue. ...
