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.

Description

technical field [0001] The present application relates to the technical field of comprehensive treatment of garden waste, in particular to a combined use of oyster mushroom cultivation and fungal residue composting for recycling garden waste. Background technique [0002] During the maintenance of urban green space, a large amount of garden waste will be generated, including plant debris such as branches, fallen leaves, and lawn trimmings. According to the China Urban Statistical Yearbook, in 2019, the area of ​​urban green space in my country reached 3.1529 million hectares, and the theoretical total amount of garden waste available resources is roughly estimated to be 16 million tons per year. With the continuous development of urbanization, its production will continue to expand. [0003] At present, garden waste in my country is still mainly treated by landfill, stacking, and incineration, which not only increases the burden on the urban management system, but also wast...
