Flammulina velutipes is a kind of food and medicinal bacterium. It is crispy, smooth, refreshing and nutritious. Production, such as improper cultivation and management, it is prone to some of the physiological diseases, here to introduce to you the five common physiological diseases and the prevention and control of mushroom, for the majority of farmers friends reference. 2. Open the umbrella ahead of time: The fruiting body is not fully grown and mature yet, the cap is too large, and the umbrella is opened prematurely. The main reason is related to the quality of the bacteria bags, followed by whether or not to be contaminated by bacteria and fungi, and in addition to air, light, humidity, and temperature in the process of fruiting, and may be attributed to the excessively low bran content of the supplements. The prevention and control measures are: strict sterilization, vaccination, good coordination of air, light, and humidity in the fruiting period, and the temperature of the common varieties of mushrooms is not higher than 15°C, and the content of bran is not less than 20%, so as to make the mycelium thick and strong. High Yield. 3. Mushrooms: The so-called “water mushroom†refers to the fruiting body that is translucent like water soaked in water and has almost no commercial value. The main reasons are: high temperature, too much water spray, slow evaporation of water, and moisture remains in the fruit body. The prevention and control measures are: the number of water sprays should not be too much, the air humidity of the mushroom room should be maintained at about 80%, and regular ventilation. 5. Lateral mushrooms: The main manifestation is that the fruiting bodies do not grow from the surface layer of the culture material, but most of them grow on the side wall of the bacterial bag. The main reasons are: the culture material bagging is too loose, and the culture material can easily grow out of the fruit bag and consume nutrients. The prevention and control measures are: When packing materials, it must be tight and elastic, and use bagging machines as far as possible to avoid the occurrence of loose bags.

1. Needle mushroom: The main manifestation is that the upper part of the fruit body is fine and the stipe is slightly thick and needle-like. The main reason is that the concentration of carbon dioxide is too high, inhibiting the growth of the cap. The prevention and control methods are: to ensure good ventilation conditions, to avoid opening the bag too late, and to carry out ventilation and ventilation once a day after bagging.
4. Flesh basal hair ties: The size of the basal hair of the fruiting body directly affects the commodity value of the mushroom. The main reason is related to humidity and air. The prevention and control measures are: Avoid air humidity is too dry or too wet, otherwise it is easy to produce hair; In addition, in the young mushroom period, it is easy to appear high concentration of carbon dioxide, oxygen is insufficient, so the oxygen content in the bag should be increased.
