Problems solved by technology

[0002] Due to the thermal insulation of plastic greenhouses, plastic greenhouses are widely used in the production of vegetables. However, in the cold northeastern region, or in the southern plateau region with great temperature difference, the disadvantage of poor thermal insulation performance of plastic films is also obvious. Ordinary plastic The insulation performance of the greenhouse is only to ensure that the temperature of the greenhouse rises during the day, but the temperature inside the greenhouse at night is less than or equal to the outdoor temperature, which has a negative impact on the cultivation of vegetables and the improvement of production efficiency.
Therefore, in production practice, people will take measures to strengthen heat preservation. At present, people generally install electric lights in the greenhouse to keep the vegetables cultivated. vegetables to keep warm, and electric lamps need to be driven by electricity, and turning on multiple electric lamps at the same time to keep the cultivated vegetables warm requires a lot of power resources. Affects the growth rate of vegetables
