How to prevent and cure Flammulina velutipes spots?

Mushrooms are indispensable ingredients in our life, among which Flammulina velutipes is deeply loved by consumers because of its delicious taste and smooth taste. Flammulina velutipes is also rich in many nutrients, often eating is good for the human body. As we all know, if mushroom cultivation has high requirements for the environment, its growth conditions must be met. What are the requirements for the growth conditions of Flammulina velutipes? How to prevent and cure the occurrence of long spots?

I. growth conditions of Flammulina velutipes

1. Temperature requirement

Flammulina velutipes is a kind of low temperature solid fungus, so the mycelium can grow normally in the range of 5-30 ℃, but it is generally required to grow well under the condition of 22-25 ℃. If the temperature is too high, the mycelium will stagnate or die. If the temperature is too low, Flammulina velutipes will appear the phenomenon of small canopy, slender handle and crazy growth.

2. Nutrients

Flammulina velutipes as saprophytic fungi can only rely on hyphae to absorb ready-made culture materials. In the specific planting process, the selection of materials is very critical, which will directly affect the quality and yield of Flammulina velutipes. The nutrients needed for the growth of hyphae and fruiting bodies are vitamins, minerals, sugar nutrients and so on.

3. Moisture requirement

During the mycelium growth period of Flammulina velutipes, if the water content of the culture material is more than 70%, the oxygen content will be reduced, which will directly affect the mycelium growth. Therefore, during the formation of fruiting body primordium, attention should be paid to air humidity.

4. Fresh air

Flammulina velutipes needs to absorb fresh air in order to grow better. Especially during the period of fruiting body formation, a lot of oxygen is consumed. If there is too much carbon dioxide in the air, it will have a negative impact on the growth of the fruiting body.

5. Lighting conditions

The hyphae and fruiting bodies of Flammulina velutipes can grow without light, but abnormal Flammulina velutipes are likely to occur if there is no light at all. A little astigmatism is the best, so it can stimulate the growth of the cap, too much light will not be conducive to the stalk growth of Flammulina velutipes. So we have to keep a small amount of light coming in the mushroom room, not completely dark.

Second, how to treat the spots of Flammulina velutipes?

In the cultivation process of Flammulina velutipes, there are often long spots, which are generally attacked by diseases, such as black spot and rust spot.

If Flammulina velutipes suffers from black spot, it will be shown on its umbrella first. At this time, you will see brown or dark brown oval spots. At first, it is as big as a needle, but over time, it will slowly become larger and the edges will be very neat. Sometimes the canopy will crack.

To prevent black spot, you must control the temperature and humidity in the mushroom room. When sprinkling water is needed in the mushroom room, do not spray water on the fruiting body of Flammulina velutipes, especially do not touch cold water. The humidity in the mushroom room should not be more than 90%, and water should be sprinkled according to the change of weather. Pay attention to ventilation after each sprinkler work is finished. Once the disease of Flammulina velutipes is found, it should be removed in time.

If Flammulina velutipes suffer from rust spot, it will usually infect the canopy of Flammulina velutipes, which will show spots with irregular edges and the size of sesame grains. Prevention work is also similar to the prevention of black spot.
