Solar greenhouse

Sunlight greenhouses are relatively simple facilities that utilize solar energy. In cold regions, vegetables are generally cultivated over the winter without heating, while the cultivation facilities for producing fresh vegetables have distinct Chinese characteristics. The structure of solar greenhouses varies from place to place, and there are also many classification methods. According to wall materials, there are mainly dry rammed soil temperature chambers, brick and stone structure greenhouses, composite structure greenhouses, etc. According to the length of the rear roof, there are long and short slope greenhouses; According to the form of the front roof, there are two fold, three fold, arch circle, micro arch, etc. According to structure, there are bamboo and wood structures, steel and wood structures, reinforced concrete structures, all steel structures, all reinforced concrete structures, suspension structures, and hot-dip galvanized steel pipe assembly structures.

The front slope is covered with insulation at night, and the east, west, and north sides are single slope plastic greenhouses with enclosure walls, collectively known as solar greenhouses. Its prototype is a single slope glass greenhouse, and the transparent covering material on the front slope is replaced by plastic film, which evolved into an early solar greenhouse. The characteristics of solar greenhouses are good insulation, low investment, and energy conservation, making them suitable for use in economically underdeveloped rural areas in China.
