Mushroom planting: early prevention of mushroom "freaks"

Abnormal mushrooms are prone to deformed mushrooms when the ventilation is not smooth and the carbon dioxide content in the mushroom is more than 0.3%. The mushroom part is too deep, and the mushrooms that grow between the cracks in the coarse soil are often deformed. Attention should be paid to the ventilation of the mushroom room.

The room of Pleurotus ostreatus and the surface of the culture material are not ventilated in time after spraying water, the humidity of the room is too high, small water droplets appear on the surface of mushroom, and rust spots will be formed over a long time. Therefore, the doors and windows should be opened for 30 to 60 minutes after each spray.

The water spraying of Pleurotus ostreatus is too little, the overlying soil layer is dry, the fruiting body can not get enough water, and the mushroom stalk produces white pith, even hollow. The main preventive measures are to spray water at the right time, and the air relative humidity of the mushroom room is kept above 85% during the mushroom production period.

The temperature difference between day and night of hard open mushroom is up to 10 ℃, or when attacked by strong cold air, it will cause mushroom to open hard. When the temperature suddenly changes, grass curtains should be built outside the mushroom room to keep the temperature stable and humidity suitable.

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