Ganoderma lucidum is high temperature bacteria, can grow between 15 ~ 35 ℃, suitable temperature is 25 ~ 30 ℃. The fruiting bodies can grow in the range of 10 ~ 32 ℃, but the optimum temperature of the radical differentiation and fruiting body is 25 ~ 28 ℃. Below 25 ℃, the fruiting body grows slowly, the hull color is also worse; higher than 35 ℃, the fruiting body will die. Ganoderma lucidum growth requires a high humidity. With the increase in temperature difference between day and night, mycelial growth of the bag longer.
Mycelial growth period, the required medium water content of 55% to 60%, air relative humidity of 70% to 80%. Fruiting body development period, air relative humidity requirements in 90% to 95%. If less than 80%, the fruiting body will have poor quality of growth, and the young growth point on the edge of the cap will become dark gray or dark brown.
Ganoderma lucidum is a good aerobic fungus, its entire growth and development process requires fresh air. Especially the fruiting body growth and development stage, is more sensitive to carbon dioxide. When the carbon dioxide content in the air increased to 0.1%, the fruiting body can not open the umbrella, grow into the staghorn branch, content of 1%, the fruiting body development is very normal, without any tissue differentiation, the formation of deformity.
Ganoderma lucidum in the process of growth and development is very sensitive to light, light on mycelial growth has a significant inhibitory effect, no dark conditions of darkest growth, when the illumination increased to 3000 lux, the growth rate of only half of the dark conditions. Fruiting body growth and development indispensable light, in 1500 ~ 5000 lux, stipe, plaster growth rapidly, stout, thick cover.
