Heavy snowfall in winter can cause various degrees of damage to vegetable greenhouses. The following general defenses can be taken to reduce losses:
1. Strengthen the shed to avoid heavy snow collapse.
2. If it is snowing during the day, do not cover it; if it is snowing at night, cover it with a layer of straw and cover it with a layer of straw.
3. Clean the snow immediately after the snow stops to prevent melting of the snow and ensure that the cover is dry to facilitate heat preservation.
4. When the weather begins to clear, slowly remove the cover to facilitate penetration into the sun.
