Prevention and treatment of mushroom "freak"

Deformed mushroom

Mainly poor ventilation, mushroom room carbon dioxide content of more than 0.3%, prone to deformed mushrooms. The mushroom part is too deep, and the mushrooms that grow between the cracks in the coarse soil are often deformed. Preventive measures, we should focus on the ventilation of mushroom rooms.

Pleurotus ostreatus

When the culture material enters the mushroom room, the humidity is too high, the ventilation of the mushroom house is too long when the coarse soil is transferred to water, the covering of fine soil is too late, the temperature is low, and so on, it is easy to produce Pleurotus ostreatus. Preventive measures should be mastered to spray appropriate amount of water, timely ventilation, so that the mycelium hanging above the clay, under the fine soil.

Pleurotus ostreatus

Sour cultivation materials, too much water in the high temperature stage before mushroom production, excessive water content in the overlying soil layer, excessive glucose topdressing, poor ventilation in the mushroom room and so on are easy to lead to red root mushroom. Preventive measures, we should adjust the pH of the culture material, the water content of the covered soil should be kept at 22%, 25%, avoid sprinkling water at high temperature, and the concentration of topdressing should be appropriate.

Pleurotus ostreatus

After spraying water on the mushroom room and the surface of the culture material, there is no timely ventilation, the humidity of the mushroom room is too high, small water droplets appear on the mushroom surface, and rust spots will be formed over a long time. As a precaution, the doors and windows should be opened for 30-60 minutes after each spray.

Pleurotus ostreatus

Too little water is sprayed, the soil layer is dry, the fruiting body can not get enough water, and the mushroom stalk produces white pith, or even hollow. Preventive measures, mainly timely and appropriate amount of water spray, mushroom room air relative humidity during the mushroom period to keep above 85%.

Pleurotus ostreatus

Day-night temperature difference of up to 10 ℃, or strong cold air attack, will cause mushrooms to open their umbrellas. Precautions: when the temperature suddenly changes, grass curtains should be added outside the mushroom room to keep the temperature stable and humidity suitable.

Pleurotus ostreatus with thin skin open early

If the density of mushroom is too high, the temperature is too high, or the humidity is low, the fruiting body grows fast and the handle is thin, which will open the umbrella early. Preventive measures, pay attention to maintain the appropriate temperature and humidity of the mushroom room, can effectively prevent the emergence of thin-skinned early umbrella mushrooms.
