Mainly produced in tropical and subtropical forest areas, some high humidity, and dim light inside the forest, born in a variety of broad-leaved trees at the base of the stem of the rotten wood and around the ground, mycorrhizal stems born in the underground rotten roots and rotting wood.
The conditions for the growth of wild Ganoderma lucidum are very special and require the following:
1. Nutrition: mainly carbon, nitrogen and inorganic salts. Ganoderma lucidum grows well on substrates containing glucose, sucrose, starch, cellulose, hemicellulose and lignin. It also requires mineral elements such as potassium, magnesium, calcium and phosphorus.
2, temperature: Ganoderma lucidum is a high-temperature type of fungus, its temperature to adapt to a wide range. Mycelium: growth temperature range 3~400C, normal growth range 18~350C, the more suitable temperature is 24~300C. the optimal temperature is 26~280C.
Poducts: the temperature range of the formation of the pods is 18~320C. the optimal temperature is 26~280C. 300C is fast developing, the texture, the color is poorer, 250C has a dense texture and a good gloss. The temperature continues to be above 350C, and it is difficult to differentiate below 180C, or even not to differentiate.
Spores: the optimum temperature for germination is 24~260C.
3. Moisture: Ganoderma lucidum mycelium in the substrate requires the optimum moisture content of 60~65%, the mycelium in the segments of wood requires that the segments of wood moisture content between 33~48%. When short segments of wood are buried in the soil, the soil water content is required to be 16~18%, while during the mushrooming period, the soil water content is required to be 19~22%. At the stage of mycelium growth, the relative humidity of air is 70~80%, and at the stage of forming substrate, the relative humidity of air is required to be between 85~95%, and should not be more than 95%, otherwise it is unfavorable for the development and differentiation of substrate formation and differentiation. Air relative humidity can be measured by a hygrometer.
4, air : Ganoderma lucidum is an aerobic fungus. The demand for oxygen is greater than that of general edible fungi, and the carbon dioxide in the air is 0.03 under normal circumstances. tests show that when the carbon dioxide content in the air is more than 0.1%, it will make Ganoderma lucidum only grow the stipe or the stipe branching without opening the cover and forming the staghorn cheese.
5, light : Ganoderma lucidum mycelium in the mycelium growth stage does not need light, light on the mycelium growth has obvious inhibitory effect. Ganoderma lucidum seed entity in the formation stage, if in the total darkness environment does not differentiate, and too strong light will also inhibit the normal differentiation of the seed entity, only in the diffuse light to reach 200 ~ 5000LUX range, so that the seed entity normal differentiation and formation. Shade degree of shade to achieve "four parts of the sun, six parts of the shade" can be. Only the west side of the perimeter should be shaded, and the other three sides should be slightly shaded according to the situation. Ganoderma lucidum entities not only have phototropism, but also have obvious geotropism, i.e., the fungal tube of Ganoderma lucidum entities has geotropic growth, regardless of the direction of growth of the fungal umbrella is upward or downward slanting, the fungal tube usually grows towards the ground, and the ground is perpendicular to the growth of the fungal tube.
