The minimum temperature for the growth of edible mycelium grown in winter is between 3-6°C. If the temperatures below 0°C are encountered, the temperature of 2-3°C can be increased by the mushroom shed (house) to reduce the frostbite of the mycelium. Mushroom (house) insulation to prevent mycelial cells from freezing and avoiding mechanical damage is the focus of current work on the cold and frost protection of edible fungi.
1. Clear the ice and snow, drain the ditch, remove the ice and snow accumulating at the top of the mushroom shed (room) and around it, and prevent the mushroom shed (house) from collapsing. Drain the ditches around the shed (house) to keep the drainage smooth and avoid rainwater. Snow water attack on mushroom material.
2. Stop the water spray immediately and try to keep the material surface dry. Because the mycelium of the edible fungus enters the hibernation state at low temperature, the water spray easily dies.
3. Strengthen the shed (house) insulation management. You can buckle a small shed in the greenhouse; Shed covered with film, straw and other insulation and dehumidify the cover. The bottom of the shed with a plastic film for the apron to reduce the bottom of the cold air attack Closing the gap to minimize heat dissipation in the gap; in the north of the greenhouse, the straw is used as a windbreak to prevent the wind and cold from entering and exiting.
