What are the control methods for mold and rot in shiitake mushroom logs?

Mushroom Cultivation 0 views
During the color-turning and fruiting period of bag-cultivated shiitake mushrooms, the rotting of the mushroom logs often affects the high quality and high yield of shiitake mushrooms. There are two types of manifestations of rotten mushroom logs. One type is the loosening and disintegration of the mushroom log. The mushroom log is loose and lacks elasticity, easily falling apart when touched by hand, and the culture material has no off odor. This mostly occurs when the mushroom log is opened from the bag for color turning or after 1-2 batches of mushrooms have already been produced. The main reasons are: during the mycelium growth process of the mushroom log, poor ventilation in the culture room causes severe oxygen deficiency, or certain mycelial heat is generated in the later stage of mycelial growth, and combined with high air temperature and failure to turn and stack the logs in time to dissipate heat, the temperature exceeds 35°C or above, causing part of the

After 1-2 batches of mushrooms are produced, if ventilation is poor and too much water is sprayed, it will also loosen and disintegrate.
