2. If the bag load is too tight or the water content is more than 65%, there is not enough oxygen in the bag to inhibit the growth rate of the mycelium.
3, the germination environment temperature is less than 20 °C, and poor ventilation, or the pH of the culture material is not appropriate, can also cause slow development of bacteria.
5. What are the reasons for the incomplete sterilization of Pleurotus eryngii?
1, when the mixing material does not absorb water, the material has a heart, especially wood chips, corn cobs and other hard texture of the culture more common.
2. No cold air is discharged during the sterilization process, and there is no good thermal cycle.
3. Insufficient sterilizing time, cease-fire in the process of sterilization, air sterilization in the sterilizing pot (tank), too much tightness, and incomplete sterilization.
