Because Flammulina velutipes is one of aerobic fungi, when Flammulina velutipes is in a well-ventilated environment with sufficient oxygen in the air, the mushroom cap develops well, and when the concentration of carbon dioxide in the air is 0.06%-4.9%, the growth of mushroom cap will be affected. When the content of carbon dioxide in the air is more than 65438 0%, the growth of bacterial cap will basically stop.

Matters needing attention in cultivating high-quality Flammulina velutipes

1, temperature

Flammulina velutipes has lower temperature requirements than common cultivated mushrooms in each growth and development stage, and the highest temperature of fruiting body differentiation is below 24 degrees, which belongs to low-temperature mushrooms.

2. Moisture

Water is an important part of Flammulina velutipes tissue. The fruiting body and mycelium of Flammulina velutipes have high water content. Similarly, water is also an important condition for bacteria to absorb nutrients and metabolites.

The water needed for the growth and development of Flammulina velutipes mainly comes from culture materials and air humidity. It is worth noting that Flammulina velutipes is a wet mushroom with weak drought resistance. Therefore, in the mycelium growth stage, the water content in the culture medium is kept at about 70%. If it is lower than 60%, the mycelium will not grow well and it is not easy to form fruiting bodies.

3. Humidity

Air humidity also has an important influence on the mycelium growth and fruiting body development of Flammulina velutipes. During the growth of mycelium, the relative humidity of air in the culture room is about 60%. Too low humidity will affect the growth of mushrooms; When the humidity is too high, when it exceeds 95%, many dark brown liquids will appear on the surface of the culture medium, and the bacteria are weak, which is prone to various miscellaneous bacteria and diseases.

In order to measure the relative humidity of the air in the culture darkroom, a simple dry-wet bulb thermometer is usually used. This kind of thermometer can be bought in general stationery stores. Please refer to its instructions.

4. Light

Flammulina velutipes is different from green plants, it does not carry out photosynthesis and does not need direct sunlight. Flammulina velutipes was injured and died quickly in direct sunlight, but indirect illumination such as glass could promote its growth.
