Oyster Mushroom Cultivation Techniques（3）

In view of the rich nutrient content in factory-made fungus bran, factory-made wood-rot fungus bran is added as an auxiliary material to new materials for secondary cultivation of oyster mushrooms, which reduces the cost of oyster mushroom cultivation and realizes the high value-added utilization of fungus bran.

The cost of raw materials can be reduced by 27% to 46.6% compared to culture media using cottonseed husks as the main material. The profit/investment ratio of cultivating oyster mushrooms with fungus bran is higher than that of culture materials using cottonseed husks as the main material.

The combination of fermentation material and short-term high-temperature treatment technology and ring paper sealing technology can solve the problem of high contamination rate in the process of cultivating oyster mushrooms with mushroom bran. The contamination rate of bacteria sticks can be controlled at 2% to 5%. Coupled with the low investment cost, this technology has strong practicality.
