Can edible mushrooms be grown in air-raid shelters?

When cultivating edible mushrooms in air-raid shelters, tunnels, or caves, a section at the entrance and exit must be kept dark, and lights should be turned off promptly to prevent pest insects from flying in.

Before cultivating edible mushrooms, cultivation rooms, tunnels, caves, and air-raid shelters must be cleaned thoroughly, and shelves, walls, and floors must be completely disinfected and treated for pests. Special attention should be paid to places where pests easily hide, such as cracks between bricks and gaps in shelves. For old cultivation rooms with severe disease outbreaks, fumigation and disinfection should be carried out. The method is to pour 80 ml of formalin into 40 g 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, the cultivation room must be sealed; after 2 days, open the doors and windows for ventilation for 24 hours, then bring in the mushroom bags. Sulfur fumigation can also be used, at a rate of 5 g per cubic meter, sealed for 48 hours, and then feed in after another 2 days.
