Why Do Oyster Mushrooms Die Soon After They Emerge?
Dead mushrooms are one of the common problems in large-scale cultivation, especially in old mushroom houses. There are many reasons for dead mushrooms, and some even have unclear causes. There are three main situations of dead mushrooms: 1. Dried mushrooms: The young mushrooms are dry and yellow, no water flows out when pinched by hand, and the water content is obviously insufficient. This situation is mostly caused by insufficient humidity. Improper ventilation of the mushroom house, such as direct blowing, insufficient water content in the material, low relative humidity in the atmosphere, or direct sunlight will cause the mushrooms to dry out. Strengthening water management will prevent mushrooms from drying out. 2. Wet dead mushrooms: The young mushrooms are wet and water-soaked, and then turn yellow or even rot. A large amount of water drips out when you pinch them with your hands. The main reason is that the water spray is too heavy, which makes the young mushroom fruiting bodies saturated with water and lack of oxygen, causing them to suffocate to death. Excessive water spraying in the mushroom room and insufficient ventilation or water accumulation at the roots of the mushrooms often cause wet mushrooms to die. Therefore, proper moisture and ventilation management will effectively solve the problem of wet dead mushrooms. 3. Sticky mushrooms: The young mushrooms grow slowly at first, then gradually turn yellow and wet, and finally the surface becomes sticky. Often appears in the second wave of old mushroom houses and beyond. This is mainly due to uncleanness of the mushroom house and is caused by bacterial infection. Once it occurs, it is difficult to heal on its own. Infectious bacteria often overwinter in the soil and are infected through water splashing onto the mushroom body during water spraying management. At this time, auxiliary drugs are needed for treatment, which can keep the yellowing clear and specialize in treating bacterial diseases. It has special effects on bacterial diseases such as macular disease and slime mold.
