2. Repair the flower greenhouses. Before the cold air comes, check the plastic film of the greenhouses carefully. Any holes and cracks should be repaired in time. The edges of the membrane connected to the ground should be compacted with soil to prevent cold air from entering the greenhouses.

3. When there is frost in the weather forecast, smoke can be smoked outside the shed that night to drive the cold, so that the temperature around the greenhouse will rise, and the temperature in the shed will increase accordingly.
4. The seedlings and weak seedlings that grow in the small shed are poor in cold resistance, and a small shed can be built on the vegetable border. The double layer protection can prevent the vegetable seedlings from freezing damage.
6. Heating of hot water If the area of the greenhouse is relatively small, a bucket with hot water can be placed in the greenhouse during frost. As the hot water radiates heat, the temperature in the greenhouse will rise, thereby preventing freezing.
7. Set up a wind barrier on the north side of the flower shed, pile up straws to form a wind barrier to keep out the wind and cold.
