The invention discloses an efficient culture medium for
pleurotus eryngii and a preparation method of the culture medium, and relates to the technical field of
pleurotus eryngii culture media. The culture medium is prepared from 45-55 parts of tea dregs, 35-45 parts of cassava residues, 30-35 parts of sustained release granules, 20-30 parts of distillers' grains, 15-20 parts of
oyster shells, 15-20 parts of
amylase, 15-20 parts of
protease, 10-15 parts of expanded
vermiculite, 10-15 parts of soybean cakes, 5-10 parts of rice
hull powder, 5-10 parts of
bran and an appropriate amount of water. Accordingly, the nutritional ingredient content is high, the produced
pleurotus eryngii is high in weight, rapid in growth, high in
disease resistance, soft in pulp quality and good in taste.
