It is best to choose sawdust from fruit trees, sawdust from broad-leaved trees such as poplar, willow, mulberry, locust tree and tung tree, and crushed cottonseed hulls, corncobs, cotton stalks and bean stalks. But the raw materials must be fresh. Trees containing aromatic substances, such as pine, cypress and fir, cannot be directly used as substrates.

Second, the appropriate cultivation period.

The best inoculation period is September, during which the average daily temperature is below 28℃, which is beneficial to indoor fungal growth. After 60~80 days of culture, the daily average temperature is not lower than 65438 02℃.

Third, cultivation management.

The specific measures and operation methods of cultivating bacterial bags after inoculation are as follows:

0~6 days after inoculation with 65438+, the mycelium is in the stage of germination and colonization, and generally there is no ventilation, and the indoor temperature should be controlled within 28℃.

After 7~ 10 days, the mycelium began to grow after eating, and the temperature was controlled at about 26℃. On the seventh day, I turned over the pile for the first time. When turning over the pile, handle it with care, check the infection of bacterial bags and miscellaneous bacteria, and deal with miscellaneous bacteria in time. After that, take air 2~3 times a day for 30 minutes each time.

1 1 ~ 15 days, the mycelium enters the vigorous growth period, the room temperature should be controlled below 24℃, and the ventilation rate should be increased for secondary turning.

After inoculation with 16~20 days, hyphae proliferated in large quantities, and the room temperature should be controlled at 22℃~24℃. At this time, it is necessary to remove the covering film of the bacterial bag in time, increase the ventilation appropriately, and evacuate the bacterial bag to prevent the bag from being burned by high temperature and infected with green mold.
