Where does the "Return to Yang Grass" Ganoderma lucidum come from? Can it be planted artificially? When will it be ready?

Ganoderma lucidum, also known as Linzhongling, Ganoderma lucidum, Mushroom, Ganoderma lucidum, is a relatively precious medicinal material in our country, with high economic value, so many people grow it. Where does Ganoderma lucidum come from? Can it be planted artificially? When will it be ready?

Main origin:

Ganoderma lucidum is native to eastern Asia, and Jiangxi is the most widely distributed in China.

Origin: cultivated in most parts of the country, Lushan is the most famous in the south.

Ganoderma lucidum is produced in Europe, America, Africa and eastern Asia. It is widely distributed in China, but it is mostly in the south of the Yangtze River, and it is distributed in the high-temperature and rainy area south of the Yangtze River. The specific provinces are: Anhui, Jiangxi, Fujian, Guangdong and Guangxi.

The species of Ganoderma lucidum in the world are mainly distributed in the tropics and subtropics of Asia, Australia, Africa and America, and a few in temperate zones. Located in the temperate zone of the Northern Hemisphere, there are only four species of Ganoderma lucidum in Europe and about five species in North America. Ganoderma lucidum is widely distributed in China, which spans from tropical to cold temperate zones.

Can it be planted artificially?

Yes, the specific methods are as follows:

I. preparation of nutrients

1. Sawdust about 75%, wheat bran about 25%, ammonium sulfate about 0.2%, water content of mixture 70%.

2. The sawdust is about 75%, wheat bran is about 25%, and the water content of the mixture is 60%.

3. Sawdust about 50%, wheat bran about 50%, urea 0.1%, water content 60%.

4. Cottonseed husk 79%, wheat bran about 20%, sucrose 1%, water content 60%-65%

5. Corn shaft residue 50%, sawdust about 30%, wheat bran about 20%, water content of mixture 60% 65%.

6. Poplar leaves 75%, rice bran (or wheat bran) 25%, water content 60%.

7. Rice straw powder 45%, sawdust about 30%, wheat bran (or rice bran) about 25%, water content of mixture 60% 65%.

II. Charging and sterilization

Mix the culture material, simmer for half an hour and then load. Conventional plastic bags can hold 0.25 to 0.3 kilograms of dry material. When bagging, the material should be compacted by hand and the material surface should be flat, then use a tapered wooden stick to pierce a 2.5 cm diameter vent from the middle of the material surface, plug the cotton plug at the mouth of the bag and wrap a layer of Kraft paper. If bottled, a jar or mushroom bottle with a volume of 500 to 1000 milliliters and a caliber of 3.3 to 4.6 centimeters can be used. The filling method is basically the same as that in the bag. After loading, put the bag (or bottle) in the pot in layers and sterilize under the pressure of 1.5 kg / square centimeter for 1 hour for 2 hours, or atmospheric pressure for 8 hours for 10 hours. It is required to be loaded, sterilized and vaccinated on the same day.

III. Inoculation and cultivation

Culture and vaccination is best carried out in the inoculation box, if there is no inoculation box, above the alcohol lamp flame or above the boiling water vapor. The inoculation room and vaccination tools should also be strictly disinfected. The staff should put on masks and wash their hands three times with soap. Take a jujube-sized strain from the bottle with inoculation rakes or tweezers and quickly put it into the cultivation bottle (bag). Then the bottle mouth (or bag mouth) is stuffed with cotton stopper and wrapped with Kraft paper, and transferred to the sterilized culture room for culture and sterilization. Keep the room temperature 24 ℃ ~ 28 ℃, the mycelium will be full in the bottle (bag) about 25 days after inoculation. In the germicidal stage, the management should be strengthened to prevent miscellaneous bacteria pollution, and those with miscellaneous bacteria pollution should be eliminated in time.

When the bottle (bag) is full of hyphae, the white buds with large fingers gradually appear on the surface of the culture material, that is, the fruiting body primordium. When its growth is close to the cotton stopper, the cotton plug can be removed, the room temperature is controlled at 26 ℃ ~ 28 ℃, the relative humidity is increased to 80% to 90%, scattered light is given, ventilation is given every day, and the bottle (bag) mouth can grow out of the stalk after about 20 days, and the end of the stalk can differentiate into a bacterial cap. When the light white or light yellow on the edge of the cap disappears, the edge of the cap stops growing and becomes hard, and it can be harvested when the color changes from bright to dark pink brown.

Planting time:

Ganoderma lucidum from inoculation to harvest takes about 50 to 60 days. In the case of artificial cultivation, there is no fixed planting time. As long as it can provide a suitable living environment for Ganoderma lucidum, it can help Ganoderma lucidum grow normally.
