What to Do When Pleurotus ostreatus (oyster mushroom) logs grow slowly? Causes and solutions
When cultivating mushrooms, mushroom logs are one of the inoculation methods, and the way logs are used differs from mushroom to mushroom. Some farmers use corncobs as logs to cultivate Pleurotus ostreatus (oyster mushrooms). Although mushroom buds appear on the mycelium, the fruiting bodies grow slowly. What should be done? Let's find out.
1. Choose varieties carefully
Cultivated varieties of Pleurotus ostreatus (oyster mushroom) can be roughly divided into 4 types according to the adaptability of the fruiting body to temperature: high-temperature type, medium-temperature type, wide-temperature type, and low-temperature type. If the variety is chosen improperly during cultivation, mushrooms may emerge late or even not emerge at all. Therefore, for the cultivation of Pleurotus ostreatus (oyster mushroom), a suitable variety should be reasonably selected according to the mushroom emergence season and the local climate.
2. Choose excellent spawn
The spawn of Pleurotus ostreatus (oyster mushroom) refers to the pure culture of its mycelium, which can be divided into mother spawn, stock spawn, cultivation spawn, etc. The spawn must not be mixed in variety, impure, or contaminated by miscellaneous bacteria, otherwise it will lead to no mushroom emergence or slow mushroom emergence in Pleurotus ostreatus (oyster mushroom). Therefore, farmers must choose excellent spawn in production to ensure the purity of the spawn, so as to avoid spawn contamination that affects the cultivation benefits of Pleurotus ostreatus (oyster mushroom) and causes economic losses.
3. Mushroom emergence management
When Pleurotus ostreatus (oyster mushroom) is emerging, several points should be noted. First, keep the mushroom shed well ventilated. If ventilation is poor, the carbon dioxide concentration in the greenhouse is high, and the air mobility is poor, it will cause slow growth and poor growth of the fruiting bodies. Second, regulate the temperature well. According to the temperature requirements for mushroom emergence of the type of Pleurotus ostreatus (oyster mushroom) variety, adjust the temperature of the mushroom emergence shed to meet the temperature needs of the fruiting bodies as much as possible. Finally, ensure humidity. The development of Pleurotus ostreatus (oyster mushroom) fruiting bodies requires a humid environment, with a humidity requirement of 75%-95%. Unsuitable humidity will also cause slow or abnormal growth of the fruiting bodies.
