The source of temperature for heat insulation is light. The strong light transmission ability during the day allows the walls, the ground, and the branches of the crop to absorb heat. At night, there is enough heat to release to the interior space. Treatment, can effectively block infrared rays from releasing heat outward (the heat must be converted into infrared rays), which greatly enhances its thermal insulation ability.

The heat preservation PO greenhouse film uses Japanese special high-tech organic insulation agent. so that most of the infrared radiation radiated from the inside of the shed is reflected back to achieve a high level of night-time insulation performance, which effectively controls heat loss. Compared with ordinary shed films, the night temperature It should be 2-4 ° C higher, which ensures the growth temperature of the crop at night, shortens the maturity period, and can effectively prevent the frost damage to the crop caused by the sudden drop in temperature at night.
