Planting edible fungi in air-raid shelter

To cultivate edible fungi in air-raid shelters, tunnels and caves, keep a distance between entrances and exits and turn off the lights to prevent pests from flying in. Clean up before cultivation, and thoroughly disinfect and kill insects on shelves, walls and floors. Pay special attention to the cracks in bricks, shelves and other places where pests are easy to hide. The old cultivation room with serious disease should be fumigated by fumigating with 80ml formalin into 40 g potassium permanganate per cubic meter. The container containing potassium permanganate is deep and the volume is more than 10 times larger than that of formalin. During fumigation, the cultivation room should be closed, and after 2 days, open the doors and windows and ventilate for 24 hours before sending the bacterial bag into it. You can also use sulfur fumigation, use 5g/ cubic meters, seal for 48 hours, and then feed in 2 days.
