Bags of mushroom bulbs grow thick white villous hyphae on their surfaces, and some grow up and fall down, then fall down and grow. The fungal skin gradually thickens; some do not even fall flat, and the color cannot be changed. This is the phenomenon of "hyperplasia".
1. The reason for the occurrence.
1 The window of the mushroom cultivation room is too small, and the interior light is too dark.
2 The moisture content of the culture material is high, and the indoor air humidity in the cultivation room is high.
3 The lack of ventilation, especially when the mycelium began to thicken and need to increase ventilation, but lack of ventilation.
4 The tilt film is too light or the film is too short.
5 Ingredients to add too much nutrients such as corn flour.
2. Control methods
1 Create environmental conditions conducive to fruit body growth during fruiting.
2 When the mushroom mycelium is thick and white, up to 2 cm in diameter and still not lodging, and there is uneven hyphae, it is necessary to open the film and vent until the growing bag and around the sticky hands are covered with a film. The next day, it is not necessary to lift the membrane, allowing the moisture on the surface to force the mycelium to fall flat and turn color. If it is still not lying down, open the film again, open the door and window, and after the material surface is dry, use a soft row brush to lightly disturb the surface mycelium and force it to turn over.
3 can also be dried in the material surface, sprayed with 5% lime clarified liquid once, sprayed and then aired, and then covered with a film, generally will fall down and turn color.
