1. Single Span Greenhouse stands for Energy-Saving Solar Greenhouse, also known as a greenhouse, and is a unique type of greenhouse in northern China. It is an Single Span Greenhouse without internal heating; even in cold seasons, it relies solely on sunlight to maintain a certain temperature level to meet the needs of vegetable crops.
2. Greenhouses utilize simple facilities to fully leverage solar energy. Vegetables are typically grown in cold regions during winter without heating, and Greenhouse, with their unique characteristics for producing fresh vegetables, are a distinctly Chinese feature.
3. The structure of Greenhouse varies depending on the region, and there are many ways to classify them. Based on wall materials, according to the length of the rear roof, there are semi-underground earthen wall greenhouses, masonry greenhouses, and composite greenhouses. Based on the form of the front roof, there are long rear slope greenhouses and short rear slope greenhouses, and types such as two-fold, three-fold, arched, and micro-arched greenhouses.
Based on structure, they are classified as bamboo-wood structures, steel-wood structures, reinforced concrete structures, steel structures, reinforced concrete structures, suspension structures, and hot-dip galvanized steel pipe prefabricated structures.
4. The front slope is covered for nighttime insulation. The east, west, and north sides are single-slope plastic greenhouses with retaining walls, collectively known as Single Span Greenhouse. They are excellent for insulation, require little investment, and are energy-efficient, making them very suitable for underdeveloped rural areas in China.
