Planting method of Phellinus igniarius

Coriolus versicolor is a common Chinese medicine. In recent years, its value has become increasingly higher, and its price has also risen accordingly. Many regions have developed artificial cultivation. Here is an introduction to the planting method of Coriolus versicolor medicinal material .

1. Phellinus igniarius bag

Phellinus igniarius is a precious Chinese herbal medicine, which is essentially a fungus. Wild mulberry igniarius mostly parasitizes on mulberry trees. To cultivate mulberry igniarius artificially, you must first cultivate mulberry igniarius bags. The mulberry igniarius bags are mainly based on sawdust, and some wheat bran can also be added. In a sterile environment, the cultured strains are inoculated into bacterial bags. Finally, a greenhouse specifically for growing Coriolus versicolor needs to be built to ensure constant temperature and humidity inside the greenhouse.

2. Fungus stage

During the fermentation period, the temperature in the culture room should be maintained at 22-28℃, the relative humidity of the air should be 50%-60%, and the room should be ventilated for half an hour every day. The bags should be turned up and down every 5-7 days. When the mycelium is 2/3 full, move it into the culture shed, loosen the bag mouth and lift it lightly with your hands, leaving a small gap. It is better to have diffuse light in the shed to avoid direct strong light. Generally, after about 25 to 32 days, the mycelium can fill the bag. Individual bags with poor mycelium development can be picked out.

3. Pornography Management

When the mycelium is fully grown, you can use a blade to cut the two ends into 5-cent coins to facilitate yellowing. When the fruits turn yellow, the temperature in the greenhouse should be maintained at 18-26℃, the relative humidity of the air should be increased to 90%-95%, and scattered light and sufficient oxygen should be provided. There should be a shallow layer of water on the ground, and water should be sprayed around the walls and spaces 3-4 times a day.

Open doors and vents for ventilation before 8 a.m. and after 4 p.m. every day. When the temperature is low, ventilate from 12 noon to 2 p.m. The primordium will swell for 3 to 5 days and gradually form a cap. You need to increase the amount of water spraying to retain moisture. If the temperature is too high, you can spray water to control the temperature. Poor ventilation can easily lead to deformities, so abnormal buds should be cut off in time.

When the color of the cap changes from white to light yellow and then to yellow-brown, the white color on the edge of the cap basically disappears, the edge turns yellow, the cap begins to become leathery, and yellow-brown mist-like spores are ejected from the back, it indicates that the mulberry yellow fruiting body is mature and can be harvested in time (usually it takes about 50 days from cutting to harvesting).

4. Harvest

One week before harvesting Coriolus versicolor, stop spraying water, close the vents, and cover the floor of the passage with plastic film to facilitate the collection of spore powder. When harvesting Phellinus igniarius, cut it from the base of the stalk with scissors or pick it lightly with hands. If conditions permit, dry it in the oven or sun to a moisture content of 12%. Put it in bags and store it in a dry room or sell it.

5. Harvest management

After harvesting Phellinus igniarius, remove the old mushroom skin at the mouth of the bag, put the culture bag back in the shed, increase the humidity to 90%-95%, and keep the temperature at around 25℃. After a week, fruiting bodies can grow on the original stipes. If the cultivation and management are carried out according to the methods of the previous stage, the second crop can be harvested in about 25 to 30 days, and generally 3 to 4 crops can be harvested. Every 100 kg of dry material can produce more than 3 kg of dry mulberry yellow finished product.

That’s it
