Growth environment of Ganoderma lucidum

Ganoderma lucidum, Ganoderma luci

Temperature

Ganoderma lucidum fruiting body primordia can occur in large numbers at 25-30 ℃, and grow slowly below 22 ℃. Although Ganoderma lucidum primordia can occur above 34 ℃, it is easy to form tumor-like protuberances after primordium formation and stop development. Ganoderma lucidum cap grows faster at 28-30 ℃, with sparse wheels, lighter surface color, longer growth time, more accumulation of active components and hard texture at 24-26 ℃, so the quality of Ganoderma lucidum grown at this temperature is better. In order to take into account the growth time and fruiting body quality, the room temperature during primordium differentiation and cap growth should be (28 ±1) ℃ and (26 ±1) ℃ respectively.

Temperature

The temperature demand of Ganoderma lucidum fruiting body has the characteristics of high humidity and constant humidity, and the suitable relative humidity is 90% Mel 95%. From the appearance of the primordium to the maturity of the fruiting body, the humidity should be kept relatively constant, so that the entity can grow normally and evenly. However, due to the long growth period of the fruiting body, high air temperature and large water evaporation, it is necessary to water the ground or gutter 3-4 times a day to achieve the required humidity. And combined with space spray water, if the humidity is normal, the shape of the top or the edge of the cover is round and regular, showing dark white, when the air is dry, this part turns gray-white, and then appears yellow, while the surface becomes rough or concave-convex, and loses luster, according to this, we can judge whether the fruiting body is short of water, if it is found to be short of water, it can spray water directly to the fruiting body, and combine with the ground (ditch) to pour (sprinkle) water. Avoid spraying directly on the cap during the spore release period, and the indoor relative humidity is reduced to 85%, 90%, a lower level.

Ventilation

The fruiting body of Ganoderma lucidum is very sensitive to the content of carbon dioxide in the air. it is measured that the fruiting body can differentiate normally when the volume fraction of carbon dioxide is less than 0.1%. When the volume fraction of carbon dioxide in the air is 0.03%, the cap differentiates rapidly and develops normally. When the volume fraction of carbon dioxide is more than 0.1%, the cap is difficult to differentiate, and the stalk can prolong the branching into antlers. Therefore, during the formation and development of the fruiting body, the indoor should always maintain good ventilation conditions. in order to solve the contradiction between ventilation and heat preservation, it is generally better to ventilate at night or early in the morning or slow air ventilation throughout the day.

Light

The fruiting body of Ganoderma lucidum is also sensitive to light and has the characteristic of directional light growth. the light intensity and light source direction have great influence on the fruiting body growth. it is measured that when the light intensity is 4000-6000LX, the fruiting body develops normally, the stalk is strong, the cover is thick, when the light is strong, the stalk is small, the undifferentiated cap or forms a small and thin cap. After the formation of the primordium of the fruiting body, the direction of the light source or the position of the cultivation bag should not be changed at will. Otherwise, it will affect the normal growth of the fruiting body, and it is easy to form abnormal Ganoderma lucidum. If it is cultivated in a vertical bag, in order to make the fruiting body develop normally, it generally transmits light on the top surface after the formation of the primordium, so that the top surface is shaded by light on one side after the cap differentiation, so that the cap grows horizontally to the light source, so that the stalk is perpendicular to the cap and the cap is fan-shaped.
