In order to cope with the continuous low temperature weather, ensure that greenhouse flowers and potted flowers are safely protected against freezing. The following simple antifreeze measures can be taken:
First, the double-layer non-woven fabric is covered on the free side of the shed and the operation channel. The non-woven fabric has the functions of air permeability, water permeability, light transmission, moisture absorption and heat preservation, and can raise the temperature from 2 °C to 3 °C and the ground temperature from 1 °C to 2 °C.
The second is to put a fire on each of the two sides of the shed, put a pot of water on the fire, and use the steam generated to heat up, which can quickly raise the room temperature.
Third, the potted flowers can be buried underground in the outdoor, the depth of the basin is flat or slightly higher than the ground, and some rotten grass and leaves are placed on the flower pot to prevent the surface from being frozen and damage the root system. You can also put the flower pot into the bamboo raft, put some soft materials such as leaves and waste paper on the top and bottom of the flower pot, and you can safely prevent freezing.
