What is the purpose of covering white king oyster mushrooms with black film? Please give an introduction. The main reason for covering white king oyster mushrooms with black film is that some mushroom bags are not filled completely with substrate in the middle, and white king oyster mushrooms will grow fruiting bodies in the gaps in the middle of the bags where the substrate is not filled.

What is the purpose of covering white king oyster mushrooms with black film? Please give an introduction
The main reason for covering white king oyster mushrooms with black film is that some mushroom bags are not filled completely with substrate in the middle, and white king oyster mushrooms will grow fruiting bodies in the gaps in the middle of the bags where the substrate is not filled. The mushrooms that develop from these fruiting bodies are all deformed mushrooms with no commercial value, yet they waste the nutrients in the substrate, and growers still have to spend time and effort removing these deformed mushrooms. If a layer of black film 15 cm wide is placed over the middle of the topmost mushroom bag, the problem of mushrooms growing from the substrate in the middle of the topmost bag can be solved. Placing a piece of black film 15 cm wide over the middle of the topmost mushroom bag creates a dark environment in the middle of the bag. A dark environment does not affect the normal growth of the mycelium, but fruiting bodies cannot form in a completely dark environment. In this way, while not affecting mycelial growth, the formation of fruiting bodies in the middle of the bag is inhibited, avoiding fruiting bodies forming in the middle of the bag and competing for nutrients, and allowing fruiting bodies to grow only at both ends of the bag. This helps concentrate nutrient supply for the growth of fruiting bodies at both ends of the bag, thereby improving the yield and quality of white king oyster mushrooms, and also avoids wasting a large amount of labor. At the same time, it can prevent growers from tearing the bag when removing fruiting bodies from the middle of the bag, which would reduce the humidity of the substrate and thereby inhibit mycelial growth. It can also prevent pathogens from invading through the tear in the bag and affecting white king oyster mushroom production.
