Straw mushroom high-efficiency medium with banana flavor, and preparation method thereof

The invention discloses a straw mushroom high-efficiency medium with banana flavor. The straw mushroom high-efficiency medium comprises, by weight, 28-32 parts of wild banana skins, 8-12 parts of aloe leaf, 1-2 parts of ultramicro silicon powder, 40-50 parts of rapeseed cake powder, 20-30 parts of bean dregs, 12-16 parts of wheat bran, 2-4 parts of zinc chloride, 2-3 parts of chitosan, 4-6 parts of egg white, 0.01-0.02 parts of protease, 1-2 parts of pyroligneous liquid, 1-2 parts of zeolite powder, 1-2 parts of quicklime and a proper amount of water. Wild banana skin powder, zinc phosphate and attapulgite are adopted to prepare organic zinc supported on attapulgite, so the medium can be conveniently absorbed by straw mushroom, and straw mushroom is endowed with a unique taste. The ultramicro silicon powder is adopted to increase the calcining resistance. The zeolite powder and quicklime are added to promote heat generation, promote heat propagation, accelerate the decomposition of raw materials and reduce heat consumption.
