Detailed explanation of the key points of Lingzhi (Ganoderma lucidum) production technology, master the key cultivation steps

In recent years, bag-cultivated Ganoderma lucidum has been widely promoted. The author has summarized many years of Ganoderma lucidum production practice, and now introduces several key production technology points as follows: 1. Choose a suitable cultivation period: In Taizhou City, Jiangsu Province, the most suitable cultivation period for Ganoderma lucidum is from April 10 to May 10, and after May 20 the bags are opened one after another for mushroom emergence. June to July each year is the plum rain season, therefore, it is necessary to ensure that all bags are opened for mushroom emergence before June 10, so that the growth of Ganoderma lucidum fruiting bodies can be in a high-temperature and high-humidity environment, thereby achieving high and stable yields. 2. The culture material must be fresh and dry: The culture material for cultivating Ganoderma lucidum must be especially fresh and dry. Fresh culture material is rich in nutrients and contains few contaminating microorganisms, which is conducive to the germination of mycelium and inhibits the growth of contaminating microorganisms. 3. Ventilation and air exchange during the mycelium growth period: Ganoderma lucidum is an aerobic fungus, and during the cultivation process of Ganoderma lucidum, attention must be paid to ventilation and air exchange. When making Ganoderma lucidum fungus sticks, it is best to seal the openings with plastic and cotton plugs. For fungus bags tied with plastic rope, after the mycelium covers the surface, micro-holes must be made at both ends of the fungus bag for ventilation. 4. Reasonable water spraying during the mushroom emergence period: During the growth of Ganoderma lucidum fruiting bodies, the air humidity in the Ganoderma lucidum room is required to be 85%-95%. Under conditions of suitable ambient temperature, too low humidity will make the Ganoderma lucidum fruiting bodies small and thin, or even stiff and unable to develop. In the early stage of fruiting body formation, water management is mainly by spraying water on the walls, bed frames, ground, and space. When the diameter of the Ganoderma lucidum cap is greater than 3 cm, with the increase in ventilation, the number of water sprayings should be increased, 3-4 times a day, and it can be sprayed directly onto the Ganoderma lucidum. 5. It is advisable to use the imitated wild cultivation method: Under the same cultivation conditions, wall-type imitated wild cultivation can increase yield by 20%-30% compared with bag cultivation. This is because during imitated wild cultivation, the soil contains the nutrients needed for the growth of Ganoderma lucidum, and the soil has good water-holding capacity, which can provide suitable, continuous, and stable moisture conditions for the growth of Ganoderma lucidum. Moreover, the mycelium extends and grows through the soil and connects into one body, which can give play to its overall advantage.
