The invention relates to a culture material for domestic
fungus culture, and especially relates to a culture material for
edible fungus and a preparation method thereof. The culture material is mainly composed of wood
chip,
bran, slaked
lime, sugarcane dreg, walnut shell,
straw, tomato, watermelon peel, and
cassia seed. The culture material is prepared by the following steps: adding wood chips, sugarcane dregs, and straws in a steam ball, adding
sodium sulfide and
sodium hydroxide, carrying out
steaming, filtering, discarding the filtrate, saving the filter residues for later use; mixing and
grinding walnut shells, slaked
lime, and
cassia seeds to obtain mixed
powder, saving the mixed
powder for later use; mixing watermelon peels, tomatoes, and
bran, squeezing to obtain a mixture of fruit and vegetable, saving the mixture for later use; evenly mixing the filter residues, mixed
powder, and mixture of fruit and vegetable, then carrying out a
microwave treatment, and adding water until the
water content reaches 28 to 30%. The culture material is rich in nutrients, can supply enough nutrients for the growth of
edible fungus, improves the quality of
edible fungus, increases the output, and shortens the production period.
