Mushroom cultivation material and preparation method thereof

The invention relates to the technical field of edible mushroom cultivation, in particular to a mushroom cultivation material and a preparation method thereof. Animal protein degreased grub powder is creatively added into the mushroom cultivation material and organically combined with plant protein wheat bran in a specific proportion, so that the variety and proportion of amino acids in the cultivation material are more suitable for growth of mushrooms, and wood chips in the cultivation material are combined, so that the yield of the mushrooms is improved. Compared with the prior art, the shiitake mushroom cultivation material has the advantages that comprehensive nutritional ingredients are provided for growth and development of shiitake mushroom hyphae and sporocarps, the hypha growth speed and the sporocarps growth and development are remarkably accelerated, meanwhile, a cultivation material subacid environment is provided through the specific proportion of the components, growth of the hyphae and the spor
