NOVELTY - Use of pre-processed/pre-treated kitchen waste is claimed as raw material for preparation of culture medium for Flammulina velutipes (golden needle mushroom).    USE - The pre-processed/pre-treated kitchen waste is used as raw material for preparation of culture medium for F.velutipes (all claimed).    ADVANTAGE - The pre-processed/pre-treated kitchen waste enables preparation of high-quality F.velutipes culture medium by combined treatment of kitchen wastes and corncob particles as main raw materials. The kitchen wastes can be effectively used as raw material for production of the culture medium hence environmentally-friendly as pollution caused by disposal of the kitchen wastes is reduced and utilization rate of high nutrient organic matters present in the kitchen waste is also effectively utilized. The preparation method of the culture medium has very high practical values.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method for preparing F.velutipes culture medium by combined processing/treatment of kitchen wastes and corncob particles as main raw materials, which involves (a) mixing coarse corncob particles of 10 mm size and kitchen garbage in a weight ratio of 1:1-1:1.2, crushing obtained mixture to particle size of 2-5 mm, adjusting moisture content of obtained pulverized mixture to 60%, and adjusting pH of the mixture in neutral range, (b) screening microbial population of thermophilic Actinomycetes, adding screened microbial population to the pulverized mixture, performing aerobic fermentation for 1-3 weeks, performing sample detection and adjusting carbon-nitrogen ratio in obtained fermented material stack to 35:1-32:1, (c) heating and drying fermented mixture and reducing water content of the fermented mixture to 30%, and (d) subjecting obtained culture medium to high-temperature sterilization and reducing water content of the culture medium to 12% or less; and (2) culture medium obtained by the above-mentioned method, comprising 20-30% corncob particles, nutritional supplements chosen from 0.1-0.2% vitamin B, 1-2% gypsum, 0.2-1% potassium dihydrogen phosphate, 0.1-0.2% magnesium sulfate, 10% crude protein, 30% crude fiber having lignin content of 10% or less, 40% or more nitrogen-free extract, 5% or less crude ash, 12% or less water and vitamin and mineral salts, where ratio of carbon and nitrogen in the culture medium is 35:1.
