Management Methods and Technical Key Points for the Color-Changing Stage of Shiitake Mushrooms
When the shiitake mushroom mycelium grows and develops into the physiological maturity stage, the white mycelium on the surface gradually turns into a brown layer of mycelial film under certain conditions, which is called mycelial color change. The depth of the color change and the thickness of the mycelial film directly affect the occurrence and development of shiitake mushroom primordia, and have a great relationship with the yield and quality of shiitake mushrooms. It is the most important link in the management of shiitake mushroom fruiting. There are many methods for color change, and the commonly used one is the bag-removal color-change method. It is necessary to accurately grasp the timing of bag removal, that is, remove the bag when the mycelium reaches physiological maturity. If the bag is removed too early, it is not easy to change color; if too late, the mycelium ages, often produces yellow water, and is prone to
