In winter, keeping the mushroom shed well, preventing the mycelium cells from freezing, and avoiding mechanical damage is the top priority of the cold-proof and freeze-proof work of edible fungi. The main technical measures to prevent freezing damage are:
1. Stop spraying water immediately and try to keep the material surface dry.
2. Strengthen the insulation management of mushroom sheds. Small arch sheds can be buckled in the greenhouse; outside the sheds, coverings such as films and straw curtains can be used to keep warm and dehumidify. Plastic film is used as an apron at the bottom of the shed to reduce the invasion of cold air at the bottom; the gap is blocked to minimize heat dissipation from the gap; the crop stalks are piled up on the north side of the shed to form a windproof barrier to prevent wind and cold; The temperature inside the mushroom shed is 3°C-5°C higher than the outside temperature, which can basically guarantee the maintenance of the activity of the mycelium.
3. Seize the opportunity for the temperature to rise at noon, and ventilate in time to prevent the cultivation material from deteriorating and becoming sour.
4. Remove the snow and ice accumulated on the top of the mushroom shed and around it in time to prevent the mushroom shed from collapsing.
5. Excavate drainage ditches around the mushroom shed to keep the drainage smooth and avoid the invasion of the mushroom material by snow water.
6. Where conditions permit, the method of secondary fermentation of mushrooms can be referred to, and steam is introduced into the mushroom shed to increase the temperature in the shed. However, the temperature of this method is not easy to master, and the difficulty is relatively high, and if it is heated for many days, the cost is high.
7. After the temperature rises steadily, spray water on the material surface in time to resume daily management.
