A detailed guide to Ganoderma lucidum cultivation techniques: learn how to grow Ganoderma lucidum
Ganoderma lucidum holds a very high social status in the traditional Chinese medicine field and has always been a species on the altar of the gods, but with the widespread application of Ganoderma lucidum spore powder in modern medicine, the cultivation of Ganoderma lucidum has also been continuously developing and expanding, and Ganoderma lucidum is no longer a species unique to deep mountains and old forests.
How to grow Ganoderma lucidum
1. Nutritional requirements of Ganoderma lucidum
Ganoderma lucidum is a saprophytic fungus with a strong ability to decompose and absorb lignin, cellulose, hemicellulose, and other substances. Sawdust and some crop straws such as cottonseed hulls, wheat bran, rice bran, corncobs, and rice straw can all be used as cultivation materials.
2. Temperature requirements of Ganoderma lucidum
Ganoderma lucidum is a high-temperature fungus. The mycelial growth temperature range is 15-40 degrees Celsius, with the most suitable temperature being 22~25 degrees Celsius. The fruiting body development temperature is 22-30 degrees Celsius, with 25~28 degrees Celsius being the most suitable.
3. Humidity requirements of Ganoderma lucidum:
During the mycelial growth stage, the relative air humidity is required to be 60% to 70%. During the fruiting body growth period, the relative air humidity is required to be 85% to 90%.
4. Air requirements of Ganoderma lucidum
Ganoderma lucidum is an aerobic fungus, and carbon dioxide has a great impact on fruiting body growth. When the carbon dioxide concentration reaches 0.1%, it promotes stem elongation and inhibits cap growth; when it reaches 0.1% to 1%, the fruiting body can still grow but forms branches and antler-like shapes; when it exceeds 1%, fruiting body development is extremely abnormal.
5. Light requirements of Ganoderma lucidum
Ganoderma lucidum is very sensitive to light during its growth and development process. The mycelium does not like light and grows fastest under dark conditions without light. The differentiation and growth of the fruiting body require relatively strong scattered light. At 1500 to 5000 lux, the stipe and cap grow rapidly and robustly, and the cap is relatively thick.
6. pH requirements of Ganoderma lucidum
Ganoderma lucidum likes to grow in a slightly acidic environment, requiring a pH range of 3 to 7, with the optimum being 4--6.
Cultivation techniques for Ganoderma lucidum
1. Choose a suitable cultivation period: In Taizhou City, Jiangsu Province, the most suitable cultivation period for Ganoderma lucidum is April 10 to May 10. After May 20, bags are gradually opened 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 mycelial germination and inhibits the growth of contaminating microorganisms.
3. Ventilation and air permeability during the mycelial growth period: Ganoderma lucidum is an aerobic fungus. 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 pierced at both ends of the fungus bag for ventilation.
4. Reasonable water spraying during the mushroom emergence period: During the growth period 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 Ganoderma lucidum fruiting bodies thin and small, or even become rigid and stop growing. In the early stage of fruiting body formation, water management mainly consists of spraying water on walls, bed frames, floors, and space. After the diameter of the Ganoderma lucidum cap is greater than 3 cm, as ventilation volume increases, the number of water sprayings should be increased, 3--4 times a day, and it can be sprayed directly onto 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 to connect into one body, allowing it to exert its overall advantage.
Harvesting and processing of Ganoderma lucidum
Use a small knife to cut from the middle of the stipe without breaking the cut surface, then spread it out to air-dry, or dry it at low temperature. If collecting spore powder, place clean plastic sheeting or smooth clean paper under the fruiting bodies on the cultivation rack, and collect it with a board brush. After the spore powder is sun-dried and dried, put it into plastic bags for storage for medicinal use.
Main producing areas of Ganoderma lucidum
Ganoderma lucidum originated in eastern Asia, and in China it is most widely distributed in Jiangxi.
Producing areas: It is cultivated in most parts of the country, with Mount Lu in the south being the most famous.
Ganoderma lucidum is produced in Europe, the Americas, Africa, and eastern Asia. It is commonly distributed in China, but mostly south of the Yangtze River. It is distributed in the high-temperature and rainy areas south of the Yangtze River. The specific provinces are: Anhui, Jiangxi, Fujian, Guangdong, and Guangxi.
In the world, the species of the Ganodermataceae family are mainly distributed in the tropical and subtropical zones of Asia, Australia, Africa, and the Americas, with a few distributed in temperate zones. Europe, located in the temperate zone of the Northern Hemisphere, has only 4 species of the genus Ganoderma, while North America has about 5 species. China spans from the tropics to the cold temperate zone, and the Ganodermataceae family has many species and a wide distribution.
The distribution of Ganoderma lucidum is very wide, which proves that it is very suitable for the growth of Ganoderma lucidum in most areas. As long as one can master all the links in the normal growth of Ganoderma lucidum, one can smoothly cultivate Ganoderma lucidum mushrooms. Therefore, growing Ganoderma lucidum at present is also an industry that rural entrepreneurs can consider.
