How should temperature be managed well during king oyster mushroom cultivation?
How should temperature be managed well during king oyster mushroom cultivation? Please give a detailed introduction. The king oyster mushroom (Pleurotus eryngii) is a medium-to-low-temperature, constant-temperature fruiting mushroom type. The optimum temperature for mycelial growth is 21-26°C, the fruiting body growth temperature is 8-20°C, and the optimum growth temperature is 12-16°C. Below 8°C, fruiting bodies are difficult to differentiate. In winter, the outdoor temperature is generally below 15°C,...
How should temperature be managed well during king oyster mushroom cultivation? Please give a detailed introduction.
The king oyster mushroom (Pleurotus eryngii) is a medium-to-low-temperature, constant-temperature fruiting mushroom type. The optimum temperature for mycelial growth is 21-26°C, the fruiting body growth temperature is 8-20°C, and the optimum growth temperature is 12-16°C. Below 8°C, fruiting bodies are difficult to differentiate. In winter, the outdoor temperature is generally below 15°C, especially at night when the temperature is around 0°C. The following points should be noted in temperature management.
1. When inoculating the substrate bags, keep the substrate temperature at around 25°C. It must not be cooled to too low a temperature, otherwise it will affect the germination of the spawn after inoculation. At the same time, the bags in the incubation room can be arranged relatively close together to stabilize the room temperature and reduce energy consumption.
2. Keep the incubation room temperature at around 25°C, and reduce the frequency and duration of ventilation. Do not ventilate at night; a short period of ventilation around midday is acceptable. Add protective measures for the bags below the vents and at the entrance and exit, to avoid cold air blowing directly onto the bags. Otherwise, after the mycelium in the bags is stimulated by the temperature difference, it often begins to fruit before the bags are fully colonized, affecting the final yield.
3. Keep the fruiting room temperature at around 15°C. If the temperature stays below 10°C for a long time during the primordium formation stage, fruiting bodies will be difficult to differentiate. If the temperature stays below 10°C for a long time after the fruiting bodies have differentiated, the fruiting bodies will grow slowly and become stunted, greatly delaying the harvest period, and the mushrooms will be short and thick, affecting their commercial value.
