What are the growing conditions for Pleurotus pulmonarius? Please provide an introduction.
The biological characteristics of Pleurotus pulmonarius and its required physiological and biochemical conditions are as follows:
1. Nutrition The main nutrient sources come from cellulose- and lignin-based raw materials. Such materials as cottonseed hulls, sugarcane bagasse, mixed wood sawdust, corn cobs, and bean stalks serve as carbon sources; wheat bran, rice bran, urea, and corn flour serve as nitrogen sources; superphosphate and potassium dihydrogen phosphate serve as inorganic salts. A carbon-to-nitrogen ratio of 20-30:1 is suitable.
2. Temperature Pleurotus pulmonarius is a medium-temperature mushroom. The optimum temperature for mycelial growth is 20-25°C, and the optimum temperature for mushroom production is 18-22°C. A temperature difference stimulation of more than 8°C is favorable for primordium differentiation.
3. Humidity When the water content of the substrate is 60-65%, mycelial growth is normal. For fruiting body growth and development, a relative air humidity of 85-95% is best. Below 70%, fruiting bodies are not easily produced; above 95%, the stipes elongate and deformed mushrooms with no cap growth appear.
4. Air During the mycelial growth stage, it can tolerate a carbon dioxide concentration twice that of air, while fruiting body growth has a weaker tolerance for carbon dioxide. If ventilation in the mushroom house is poor and the carbon dioxide concentration is too high, immature fruiting bodies are prone to death.
5. Light Mycelial growth does not require light, while the fruiting body differentiation and development stages require stimulation by scattered light. Generally, a light intensity of 300-500 lux is suitable. If the light intensity in the mushroom house is too strong, primordia are not easily formed, or the stipes become thick and short and the caps are difficult to expand.
6. pH value This product prefers a slightly acidic environment, and mycelia grow normally at a pH value of 5.8-6.2.
