Prevention and treatment of mycelial death of Pleurotus ostreatus during growth period

Published: 2024-11-05 Author: mysheen
Last Updated: 2024/11/05, The exuberant mycelium of Pleurotus ostreatus is white, sturdy and dense, and develops forward in a fan shape. Some mycelia suddenly yellowed about 10 days after inoculation and gradually died and disappeared. For this phenomenon, some mushroom farmers think that the greater the water content in the culture material, the higher the yield, and increase the water content when blending. There are also some mushroom farmers do not understand the meaning of water content, mistakenly for culture material water content of 65%, for every 100 kg of material plus 148 kg of water. In order to calculate the water content correctly, the water content of the culture material itself should be taken into account.

There are also some mushroom farmers do not understand the meaning of water content, mistakenly for culture material water content of 65%, for every 100 kg of material plus 148 kg of water. The correct method of calculating the water content of the culture material should also take into account the water content of the culture material itself. generally, the water content of the culture material is more than 10%. If the culture material is too wet and exceeds the limit of mycelial growth, it will lead to poor air permeability and hypoxia. A large number of moisture-loving and anaerobic bacteria will breed, resulting in the death of Pleurotus ostreatus mycelium. In addition, the temperature is too high, disinfection is not strict, there will be bacterial contamination. Pleurotus ostreatus is tolerant to low temperature but not to high temperature. the mycelium grows slowly when the temperature is more than 28 ℃, but the bacteria multiply in large numbers at high temperature, and can secrete toxins (pungent smell) in the process of growth, which can inhibit and kill the hyphae of Pleurotus ostreatus.
