<a href="">Sunlight greenhouse</a> is one type sorted out by the availability of the heating equipment in the greenhouse, namely unheating greenhouse. It mainly depends on the natural warming by sunlight and nightly thermal insulating equipment to maintain the inside temperature. It generally adopts more simple facilities, making full of solar energy. In cold areas, it makes the cultivation of winter vegetables by unheating. The sunlight greenhouse is the unique facility in China with the distinct Chinese characteristics. The greenhouse structure diversifies in various regions with many kinds of classification methods. According to the wall materials, it mainly includes adobe soil greenhouse, masonry structured greenhouse, composite-structured greenhouse and so on. According to the rear roof length, it includes the long back-slope greenhouse and short back-slope greenhouse. According to the front roof form, it includes the two-folding type, three-folding type, arch type, micro-arch type and so on. According to the structure, it includes bamboo, wood and steel, reinforced concrete, steel, and hot dip galvanized steel pipe assembly.
The covering material uses the sunlight board and single-layer film.
The greenhouse span includes 6.5 m, 7 m, 7.5 m, 8 m, 9 m, and 10 m. it is designed according to different areas, different climate conditions and the requirements of customers.
Features
1) It adopts column-free structure with large span and ample space, suitable for mechanized operation.
2) It has reasonable angle of roof lighting, sufficient indoor lighting, good insulation performance, and obvious energy saving effect.
3)It uses composite thermal insulation wall, interior wall heat preservation and exterior wall insulation, easy to form the microclimate in the greenhouse.
4)Saving materials and low cost.
5)It is suitable for enterprises of flower planting and vegetable production, widely used in tourism demonstration gardens.
The seedbed can make full use of the greenhouse space, isolated from soil, so that soil microbes donesn't infectand harm plants reducing diseases and insect pests. It has good air and moisture permeability. The seedbed can be repeatedly used for 5-8 times of seeding every year.
