Causes and Control Methods of Deformed Mushrooms in Greenhouses
1. Hollow white-stem mushrooms. The mushroom stems become loose and white, and in severe cases shrink to form a hollow center.

When the relative air humidity is below 85%, the water content of the casing soil layer is relatively low, and the temperature inside the mushroom house is above 18°C, the mushrooms grow quickly and evaporate water quickly, causing the water absorbed by the mushroom body to be less than the water lost through transpiration. Control methods: spray water promptly during the day to keep the relative air humidity at 90%, and ventilate promptly after spraying water in the morning and evening to lower the greenhouse temperature, keeping it at 14-
