How to use green house light to keep the greenhouse warm

The thermal insulation of solar greenhouse light consists of thermal insulation enclosure structure and movable thermal insulation quilt. The thermal insulation material on the front slope shall be made of flexible material to be easy to put away after sunrise and put down at sunset.

The research and development of new front roof insulation materials(green house light) mainly focus on the requirements of convenient mechanized operation, low price, light weight, aging resistance, waterproof and other indicators.

The solar greenhouse(greenhouse light) is mainly composed of enclosure wall, rear roof and front roof, which is referred to as the "three elements" of the solar greenhouse. The front roof is all the daylighting surface of the greenhouse. During daylighting, the front roof is only covered with plastic film for daylighting. When the outdoor light is weakened, the plastic film shall be covered with movable thermal insulation quilt in time to strengthen the thermal insulation of the greenhouse.

Due to the development of plastic industry and the easy damage of glass, most rural solar greenhouses use plastic film as roof material. In particular, the plastic solar greenhouse rising on the basis of soil greenhouse in northern China has obvious characteristics of high efficiency, energy saving and low cost. It is deeply welcomed by vegetable farmers and consumers. It is one of the effective measures to develop high-yield, high-quality and efficient agriculture, and will develop faster. Practice has proved that satisfactory results can be obtained when the outdoor minimum temperature is not lower than - 25 ℃ and the indoor temperature can be maintained above 5 ℃ by using the special structural performance of plastic solar greenhouse.
