Can reishi mushroom (Ganoderma) be cultivated artificially? Introduction to its origins and planting time

Reishi mushroom, also known as Linzhongling, Chizhi, Hongzhi, Danzhi, Ruicao, Muzhiling, Junzhiling, Wannianxun, and Lingzhi grass, is a relatively precious medicinal material in our country and has high economic value, so many people cultivate it. So where does reishi mushroom come from? Can it be cultivated artificially? When is the best time to plant it?

Main producing areas:

Reishi mushroom 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, and Mount Lu in the south is the most famous.

Reishi mushroom is produced in Europe, the Americas, Africa, and eastern Asia. It is widely distributed in our country, but mostly south of the Yangtze River, in the high-temperature and rainy zones south of the Yangtze River. The specific provinces are: Anhui, Jiangxi, Fujian, Guangdong, and Guangxi.

The species of the Ganodermataceae family in the world 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 Ganoderma genus, while North America has about 5 species. Our country spans from the tropical to the cold temperate zone, and the Ganodermataceae family has many species and a wide distribution.

Can it be cultivated artificially?

Yes, the specific method is as follows:

1. Preparation of nutrients

1. About 75% miscellaneous wood sawdust, about 25% wheat bran, about 0.2% ammonium sulfate, and the moisture content of the mixed material is 70%;

2. About 75% miscellaneous wood sawdust, about 25% wheat bran, and the moisture content of the mixed material is 60%;

3. About 50% miscellaneous wood sawdust, about 50% wheat bran, 0.1% urea, and the moisture content of the mixed material is 60%;

4. 79% cottonseed hulls, about 20% wheat bran, 1% sucrose, and the moisture content of the mixed material is 60%-65%;

5. 50% corn cob residue, about 30% miscellaneous wood sawdust, about 20% wheat bran, and the moisture content of the mixed material is 60%-65%;

6. 75% poplar leaves, 25% rice bran (or wheat bran), and the moisture content of the mixed material is 60%;

7. 45% rice straw powder, about 30% miscellaneous wood sawdust, about 25% wheat bran (or rice bran), and the moisture content of the mixed material is 60%-65%.

2. Filling and sterilization

After the culture material is mixed, let it sit for half an hour, then fill it. Conventional plastic bags can hold 0.25-0.3 kg of dry material. When filling the bag, press it firmly by hand, and the material surface should be flat. Then use a conical wooden stick to poke a ventilation hole with a diameter of 2.5 cm from the center of the material surface, plug the bag opening with a cotton plug, and wrap it with a layer of kraft paper. If filling bottles, wide-mouth bottles or mushroom bottles with a volume of 500-1000 ml and a mouth diameter of 3.3-4.6 cm can be used, and the filling method is basically the same as the bag method. After filling, arrange the material bags (or bottles) in layers in the pot and sterilize under a pressure of 1.5 kg/sq cm for 1-2 hours, or sterilize at normal pressure for 8-10 hours. It is required to fill on the same day, sterilize on the same day, and inoculate on the same day.

3. Inoculation and cultivation

Inoculation for cultivation is best carried out in an inoculation box. If there is no inoculation box, it can also be done above the flame of an alcohol lamp or above boiling water steam. The inoculation room and inoculation tools should also be strictly disinfected. The workers should wear masks and wash their hands with soap three times. Use an inoculation rake or tweezers to take out a piece of spawn the size of a jujube from the bottle and quickly put it into the cultivation material bottle (bag). Then plug the bottle opening (or bag opening) with a cotton plug and wrap it with kraft paper, and move it to a sterilized cultivation room for cultivation and sterilization. Keep the room temperature at 24°C-28°C. About 25 days after inoculation, the mycelium will fill the bottle (bag). During the mycelial growth stage, management should be strengthened to prevent contamination by miscellaneous bacteria, and contaminated ones should be eliminated in time.

When the bottle (bag) is filled with mycelium, white finger-sized mushroom buds, namely the primordia of the fruiting body, gradually appear on the surface of the culture material. When their growth is close to the cotton plug, the cotton plug can be removed, the room temperature should be controlled at 26°C-28°C, the relative humidity should be increased to 80%-90%, scattered light should be provided, and ventilation should be carried out every day. After about 20 days, the stipe can grow out of the bottle (bag) opening, and the cap differentiates at the end of the stipe. When the light white or light yellow color at the edge of the cap disappears, the edge of the cap stops growing and hardens, and when the color changes from bright to dark pinkish brown, it can be harvested.

Planting time:

Reishi mushroom takes about 50-60 days from inoculation to harvest. Under current artificial cultivation conditions, there is no fixed planting time. As long as a suitable living environment for reishi mushroom can be provided, it can help reishi mushroom grow normally.
