Solar greenhouse, commonly known as greenhouse, is built with insulation materials and steel skeleton with the functions of heat preservation, moisturizing, cold protection, and anti-freezing. The greenhouse is mainly used for the planting and breeding of vegetables, flowers, fruits, etc. in winter, as well as the construction of some factory farming and facility agriculture.
According to the wall material, the solar greenhouse is mainly divided into dry soil greenhouse, masonry structure greenhouse, composite structure greenhouse, etc. According to the length of the rear roof, there are long back slope greenhouses and short back slope greenhouses;According to the form of the front roof, there isTwo-fold type, three-fold type, arch round type, micro arch type, etc.
According to the structure, there are bamboo and wood structure, steel and wood structure, reinforced concrete structure, all-steel structure, all-reinforced concrete structure, suspension structure, hot-dip galvanized steel pipe assembly structure.
The greenhouse is mainly used for the planting and breeding of vegetables, flowers, fruits, etc. in winter, as well as the construction of some factory farming and facility agriculture.
The thermal insulation performance of the solar greenhouse is also better than that of the film greenhouse, and the solar greenhouse has three more walls, the back wall and the gables on both sides. The upper part of the solar greenhouse can also be covered with an insulating quilt to increase its thermal insulation effect.
The greenhouse is covered with plastic film. It is suitable for large-area coverage, because it is light in weight, has good light transmission and thermal insulation performance, strong plasticity, and is inexpensive.
The thermal insulation of the solar greenhouse is composed of two parts: the thermal insulation enclosure structure and the movable thermal insulation quilt. The insulation of the front slope should be made of flexible material so that it is easy to stow up after sunrise and lay down at sunset.
