Do a good job in repairing and consolidating the damaged greenhouse of Dendrobium candidum. First of all, repair the damaged greenhouse film and close the greenhouse film to prevent cold air from entering the greenhouse. Generally adopt the form of “greenhouse + middle shed + small shed” or “greenhouse + sunshade + middle shed” to carry on the greenhouse multi-layer covering heat preservation treatment. Then reinforce the Dendrobium candidum greenhouse. Along the longitudinal axis of the large (medium) shed, a support such as bamboo is used to support and strengthen the roof every 2-3 meters, so as to improve the compression resistance of the shed and prevent the shed from falling under snow pressure. If there is external shading equipment on the scaffolding, the shading net on the external shading should be tightened to prevent damage caused by snow pressure. Special snow sweeps should be provided.

When parking, put the front and rear and left and right sides of the car on the sunscreen, which can reduce the thermal effect of solar radiation on the temperature in the car.
two。 Skylight / panoramic skylight. This thing is like a TV, the bigger the better. The air in Shenzhen is not bad. I like to open the front window + skylight to blow the natural wind when I commute to and from work in the morning and evening. You say the air in your city is bad? Then there must be a time to swim in the mountains with good air, right? At that time, it was also very comfortable to open a skylight to embrace nature. Cold winter, do not open the skylight, only open the sunshade to let the sun in, is also a very warm and comfortable thing.
