The invention relates to a method for producing Coprinus comatus by using the anniversary of the soil hole. The method for producing Coprinus comatus by using the anniversary of the soil hole is to use the wine tank as the cultivation raw material and the soil hole as the cultivation environment. The cultivation mode of "inside mushrooming" is realized through 8 steps of soil hole excavation, strain production method, cultivation material formula, cultivation material fermentation treatment, mushroom bag production, mushroom bag growth, soil covering and mushroom fruiting management. The invention uses a manually excavated soil hole as a production site, and provides a cultivation mode of "growing fungus in the hole and fruiting in the hole". Coprinus comatus does not need refrigeration or heating equipment, and it can meet the growth of Coprinus comatus fruiting bodies in a natural state, realizing the annual production of Coprinus comatus; using new cultivation raw material distiller's grains, shortening the processing time of cultivation materials, reducing labor costs, and reducing production costs .
