Solar energy is the main source of solar energy, and at night the temperature is covered in front of the house for the single-house production in winter. The structure of the energy-saving solar greenhouse consists of three main components: first, a support structure consisting of a homogenous or heterodox complex of the north wall and the east and west hills wall, which typically uses mud walls, grass walls or double hollow brick walls; second, the front floor of the house, which consists of a slab of different materials, such as bamboo poles, bamboo blades, steel bars, prefabricated arches or zinc plating pipes, covered by a sheet of shrubs and grass plasters, which are covered by the above; and third, the rear of the slurry, grass mud, wheat slurry or slag, gas-cement plates and polybenzofoam. In addition, cold-proof ditches should be built at the base of the greenhouse, insulated from the heat and heat, so as to ensure stability of the ground; small windows could be installed in the back wall for the summer ventilation; and a buffer workshop should be built on the side of the greenhouse at one end or one end to prevent cold air from entering and being used for storage, otherwise cotton curtains should be placed to protect the temperature。
The appropriate sizes of the energy-saving solar greenhouses are: 5. 5 ~ 8 m, with a common width of 6 ~ 7 m; 2. 8 ~ 3. 2 m, with a ridge height of 2. 8 ~ 3. 2 m; 50 ~ 70 m; the archeal foot of the front face (the front room facing the ground corner) 50° ~ 60°, the middle section 20° ~ 30°, and the preceding section 10°, which facilitates winter light; the north towards the south and 5° 10°; and the back wall height of 1. 6 ~ 1. 8 m, with an angle of around 30°, the rear slope is more suitable at 1. 2 ~ 1. 4 m, with better light at temperature. The distance between the greenhouses is associated with the height and latitude of the greenhouse, generally planning the construction of the greenhouses cluster at a ~2. 5 times the height of the ridge. Daylight greenhouses are mainly used for the planting of hot fruit in autumn, winter or early spring, and some of them are equipped with wet curtains, wind machines and sunnets for summer cooling, which are used for anniversary production。
