Key Technical Points for Disaster Resistance and Mitigation and Spring Management of Edible Fungi

1. Clear away ice and snow, dig ditches for drainage. Promptly remove accumulated ice and snow from the top and surroundings of mushroom sheds (houses) to prevent them from collapsing. Dig drainage ditches around the mushroom sheds (houses) to keep drainage smooth and avoid rain and snowmelt attacking the mushroom substrate. 2. Stop spraying water and keep the substrate surface as dry as possible. Because at low temperatures the mycelium of edible fungi enters a dormant state, and spraying water can easily cause death. 3. Strengthen heat preservation management of mushroom sheds (houses). Small arched tunnels can be set up inside the greenhouse, and coverings such as plastic film and straw curtains can be added outside the shed for insulation and dehumidification. Use plastic

1. Clear away ice and snow, dig ditches for drainage. Promptly remove accumulated ice and snow from the top and surroundings of mushroom sheds (houses) to prevent them from collapsing.

2. Stop spraying water and keep the substrate surface as dry as possible. Because at low temperatures the mycelium of edible fungi enters a dormant state, and spraying water can easily cause death.

3. Strengthen heat preservation management of mushroom sheds (houses). Small arched tunnels can be set up inside the greenhouse, and coverings such as plastic film and straw curtains can be added outside the shed for insulation and dehumidification. Use plastic film as a skirt at the bottom inside the shed to reduce the invasion of cold air from the bottom; block up cracks to minimize heat loss through them as much as possible; stack crop straw on the north side of the greenhouse to form a windbreak for wind protection and cold prevention; reduce the number of times of entering and leaving the mushroom house, which can make the temperature inside the mushroom shed (house) 3-5°C higher than the outside, basically ensuring the maintenance of mycelial activity.

4. Spring management. After the temperature steadily rises, spray water on the substrate surface in a timely manner and resume routine management. After the button mushroom mycelium has been cultivated for a long time through the winter, nutrient conversion is sufficient, and a flush of mushrooms will be produced in spring, so sufficient moisture must be ensured. Especially when the temperature is relatively high, heavy watering is needed, and at the same time ventilation and oxygen supplementation are also needed. In the early stage, when the temperature is relatively low, focus on heat preservation and moisture retention, ventilate less, spray water lightly, and prevent low temperatures from damaging the mycelium. In the later stage, focus on cooling and humidifying, increase ventilation, make full and good use of water, and prevent high temperatures from killing the mushrooms.
