What kind of environment is suitable for oyster mushroom (Pleurotus pulmonarius) growth? Please introduce it.
The environment suitable for oyster mushroom (Pleurotus pulmonarius) growth can refer to the following:
Nutrition
The growth and development of oyster mushroom (Pleurotus pulmonarius) require carbon, nitrogen and various mineral nutrients. It is a saprophytic fungus, and like other fungi, it does not contain chlorophyll and cannot carry out photosynthesis to produce nutrients on its own, relying entirely on ready-made organic matter for its livelihood. During its development, the carbon, nitrogen, minerals and growth factors it needs are all obtained from the cultivation substrate.
Temperature
The humidity range for mycelial growth is 10-35°C, and the optimum temperature for growth is 25-27°C. When the temperature is below 10°C, mycelial growth basically stops; below 20°C, mycelial growth is slow. When the temperature is above 30°C, the mycelium grows sparsely, turns yellow in color and is prone to aging; when the temperature is above 37°C, mycelial growth stops. The fruiting body has a relatively wide temperature range for growth, and can produce mushrooms under conditions of 10-32°C, which is different from other oyster mushrooms. The optimum temperature for primordium formation and mushroom bud growth is 15-20°C; when the temperature is below 10°C, primordia are rarely produced again. Below 15°C, the fruiting body grows slowly. When the temperature is above 25°C, the mushroom buds grow quickly and mature early, and the caps are mostly funnel-shaped when mature. During the fruiting stage, if there is a relatively large diurnal temperature difference as a stimulus, primordia are easily produced.
Water and Humidity
The basic requirement for mycelial growth is a water content of 65%. From primordium formation to fruiting body maturity, the relative air humidity is required to be 85-90%. When the relative air humidity is below 70%, few primordia are produced and the mushrooms are prone to drying out and wilting. When the relative humidity is above 95%, the fruiting bodies are prone to becoming soft and rotting.
Air and Light
At the mycelial stage, no special ventilation conditions are needed; at the fruiting body stage, good ventilation conditions are required. If the CO2 concentration in the air is higher than 0.1%, deformed mushrooms with small caps and long stipes are very likely to form. At the mycelial stage, no light is needed; at the fruiting body stage, light is needed, and scattered light can induce primordium formation and differentiation. Without light, fruiting bodies cannot be produced. The fruiting bodies grow normally between 200-2000 lux of light; if the light is too dim, deformed mushrooms are easily formed, and if it is too strong, especially direct light, the fruiting bodies are prone to drying up.
