Detailed Explanation of Key Technical Points for Cultivating Edible Fungi in Air-raid Shelters

When cultivating edible fungi in air-raid shelters, tunnels, and caves, there should be a section at the entrance and exit kept dark, and lights should be turned off promptly to prevent insect pests from flying in. Before cultivation, clean thoroughly, and thoroughly disinfect and disinfect against insects the shelves, walls, and floor. Pay special attention to places where insect pests are likely to hide, such as brick cracks and shelf gaps. For old cultivation rooms with severe disease outbreaks, carry out fumigation disinfection by pouring 80ml of formalin into 40g of potassium permanganate per cubic meter of volume for fumigation; the container holding the potassium permanganate should be deep, and its volume should be more than 10 times that of the formalin. During fumigation, keep the cultivation room sealed; after 2 days, open the doors and windows for ventilation and air exchange for 24 hours, then bring in the fungus bags. Sulfur fumigation can also be used, with an amount of 5g per cubic meter, sealed for 48 hours, and then feed in after another 2 days.
