Pleurotus ostreatus bag ventilation four skills
Pleurotus ostreatus bags are low-cost, high-efficiency, and convenient to manage. However, when the bags are planted, they are directly tied with ropes, which often cause poor ventilation, affect germs, cause pollution, and even lead to failure of cultivation. Here are some ventilation tips: One is the ventilation plug method. With wheat straw, cotton velvet and other materials, the two ends of the bag are plugged into ventilation plugs. The size of the plug depends on the size of the bacteria bag. The big bag has a big plug and the small bag has a small plug. It depends on the germination temperature. When the germination temperature is low, the plug can be smaller, and vice versa. The second is the collar method. Trumpet ring can be purchased, and the tampon can be added after the mushroom bag is attached. If the bell mouth ring is not available, it can also be made by plastic strapping (cut into pieces, welded with a soldering iron into a ring), and the external kraft paper can be sealed with a rubber band. Note that the collar should be tightly set to prevent measurement off. The third is the vent method. Use a sewing machine needle to place a row of holes 6 cm away from the bag. The hole spacing is about 1 cm. When the material is loaded, the bacteria can be broadcast at the puncture hole. Zhakong should not be too much, and pay attention not to operate the bag in the hole, otherwise the bag is easy to crack during loading. The fourth is the ventilation hole method. Using a thick tapered wooden stick with a thumb, three holes of 6 cm in depth are drilled in triangles on each side of the packing bag. A hole is then strung in the middle sowing spot and the bag is placed in a sterile room. Holes should be lighter and not too powerful. Ningbo Staneex Imp. & Exp. Co., Ltd. , https://www.staneex.com
