In order to promote the growth of yster mushroom, mushroom farmers mostly adopt the method of post-perforation and oxygenation. However, many mushroom farmers punch too many holes, which leads to the phenomenon of "burning mycelium", that is, the mycelium in the mushroom bag is burned due to high temperature.
Because yster mushroom is cultivated with raw material, especially before the mycelium is half full, if there are too many holes, the microbial activity will be vigorous under the condition of sufficient oxygen content, resulting in an increase in material temperature. When the temperature of the mycelium bag material is higher than 35°C, it will cause "burning mycelium".
For yster mushroom cultivated with raw materials, there are generally three methods of punching holes in the fungus bag: one is to use a sewing machine to "perforate the fungus bag with micro holes" before bagging; The second is to punch holes on both sides of the bag after bagging. At this time, care should be taken to avoid the dressing opening when punching, to prevent the dressing opening from spreading, so that the cultivation material will be spilled, which will affect the growth of mycelium and fruiting; The third is to punch holes around the mycelium bag in the process of growing mycelium to increase the amount of oxygen and promote the growth of mycelium. But at this time, you must pay attention to choosing a good punching tool when punching holes. , or small mushrooms may appear during later fruiting, resulting in a waste of nutrients. If you use a tool with a diameter of about 0.5 cm to punch holes, generally 4 to 5 holes are enough.
