Detailed Explanation of Key Technical Points for Autumn Management of Button Mushrooms

To achieve stable and high yields of button mushrooms in autumn, water management must be the key focus. With proper watering, the mycelium grows vigorously, fruiting bodies form abundantly, and the number of fruiting flushes increases; with excessive watering, the mycelium will shrink and recede, primordia will form poorly, and the mushroom fruiting bodies will develop "rust spots" and "red roots"; with insufficient watering, the fruiting bodies will not be plump, and flat caps, sunken caps, or scales on the surface will appear.

The key focus of water management should be to increase the relative air humidity, and when spraying water, it should be flexibly controlled according to the fruiting situation, the moisture conditions of the compost and casing soil, and changes in weather. Generally, spray more when there are many mushrooms, spray more on sunny days, and spray more when the compost and casing soil are relatively dry; otherwise, spray less. When spraying water, point the nozzle away from the mushrooms; do not spray directly onto them.
