Oyster mushroom cultivation-mushroom residue composting combined garden waste recycling process

Abstract

The invention provides an oyster mushroom cultivation-mushroom residue composting combined garden waste recycling process. According to the application, the garden waste particles are used for culturing the mushrooms, and the complex structure of lignin in the garden waste is destroyed by using extracellular enzymes such as laccase and peroxidase secreted by hyphae, so that organic matter in mushroom residues obtained after the mushrooms are harvested is more easily degraded by aerobic microorganisms. The oyster mushroom sporocarp and the high-quality organic fertilizer can be obtained through bioconversion, the cost of a mushroom culture medium can be reduced through resource utilization of garden waste, and the degradation effect of hypha secretions on lignocellulose is fully utilized, so that the mushroom residue composting period is greatly shortened, the quality of the organic fertilizer obtained through composting is improved, and the 100% resource utilization of the garden waste is realized.
