1. Temperature: Ganoderma lucidum is a high-temperature variety. The temperature range of Ganoderma lucidum mycelium growth is 20-35℃, and the optimum temperature is 25-28℃. When the temperature is lower than 20℃ for a long time, the surface hyphae and bacterial buds will turn yellow and stiff, and even if the temperature is raised later, it is difficult for the fruiting body to grow well. If the temperature exceeds 37℃ for a long time, the fruiting body will die. The temperature is low and the growth is slow, and the growth stops completely when it is lower than 6℃ and higher than 35℃.
2. Humidity: The water content of the culture medium is 55%-60%, and the water needed for the growth of fruiting bodies mainly comes from the culture medium. In general, there is no need to spray water on the solid surface, as long as the relative humidity of air is kept at 85%-90%, it can grow normally. If the humidity is lower than 60% for 1-2 days; Fresh and tender fruit bodies lose water, and the fruit bodies grow slowly or stiffly. So the culture room should be sprayed with water 3-4 times a day.
3. Illumination: Ganoderma lucidum is a fungus with obvious phototropism, and its fruiting body grows to the side with strong light. Insufficient light, small fruiting body, thin cover, indoor light should be kept above 500 lux, and scattered light should be uniform.
4. Air: Fruit bodies are particularly sensitive to carbon dioxide in the air. Poor ventilation, the fruiting body is not easy to open or become deformed. According to related experiments, when the carbon dioxide in the air exceeds 1%, the fruiting body will be deformed (antlers). Therefore, the germination stage should be ventilated in time according to the opening of the film.
5.pH value: Ganoderma lucidum likes to grow in acidic environment, and the pH value of the culture medium can grow in the range of 3-7, and the suitable pH value is 4-5.
I hope you can get better, and you can keep asking questions if you have any questions.
