Multi-span film greenhouse is multi-span made based on single arch shed, which is generally divided into simple multi-span arch greenhouse and high-matched multi-span arch greenhouse. At present, multi-span film greenhouse is mainly used in breeding and seedling, flower production, aquaculture, medicinal materials, edible fungi cultivation and other production greenhouses.
1. simple multi span film greenhouse
Application: spring and autumn high value vegetables, flowers, herbs, edible fungi and so on.
Configuration: Its skeleton adopts hot-dip galvanized rectangular or circular tubes, with a trench at the top and ventilation window, which is the same as the basic structure of the arch shed.
Advantages: large internal space, suitable for large-scale and factory operation, and high land utilization rate.
2. high configuration multi-span film greenhouse
Application: stereo cultivation, flower culture, aquaculture, seedling breeding, scientific research and so on.
Specification: High-matching multi-span film greenhouse is an upgraded version of simple multi-span greenhouse, which adds internal and external shading, damp curtain fan cooling, side-turning window ventilation, warming and insulation systems.
Advantages: It overcomes the problems of summer cooling and winter heat preservation, especially adding double-layer film, it can effectively improve the heat preservation effect of greenhouse in winter and reduce the operation cost in winter.
