1. The last batch of bagged mushrooms was sprayed out, probably because the lignin content of cork was low, and the mycelium ate quickly, leaving many gaps after eating.
2. In the discoloration period, when the temperature is lower than 22℃ for a long time and the temperature difference is large (5 ~ 8℃), mushrooms will appear in the bag;
3. The mushroom sticks in Xia Hou are waiting for the growth of mushrooms, and the outer plastic bag of the stick head is cut open, and the exposed water-retaining film bag is relatively thin;
4. It is too late to take off the bag, the mycelium is mature, and it has the nutritional conditions for fruiting, and the environmental conditions are suitable for fruiting.
