There are four measures for anti-freezing of flowers and plants, and prevention and control of diseases of edible fungi.

1. Spray the new lipid film in time in the shed, which can quickly form a transparent protective film on the ground to keep warm and prevent germs from infection.

Second, in the shed around the empty bed surface and operation channel covered with double-layer non-woven fabric. Non-woven fabric has the characteristics of air permeability, water permeability, light transmission, moisture absorption and heat preservation, which can increase the temperature by 2℃~3℃ and the ground temperature by 1℃~2℃.

Third, put a fire at both ends of the shed, put a pot of water on the fire, and use the generated steam to heat it, which can quickly increase the room temperature.

Fourth, potted flowers can be buried underground outdoors, the depth of the pot edge and the ground level or slightly higher than the ground, and then spray the ground with a new lipid film to keep warm and freeze, and then put some rotten grass, leaves, etc. on the flowerpot to prevent the ground from freezing and damage the roots.
