Double arch double film greenhouse

Double arch double film greenhouse is a practical protective cultivation facility. Due to its easy construction, convenient use, and low investment, it has been widely adopted by countries around the world with the development of the plastic industry. Using materials such as bamboo, wood, steel, and covered with plastic film to build an arched shed for cultivating vegetables can advance or delay supply, increase yield per unit area, and defend against natural disasters, especially in northern regions where fresh and tender vegetables can be supplied during the early spring and late autumn off-season.   

The double arch double film greenhouse fully utilizes solar energy, has a certain insulation effect, and can adjust the temperature and humidity inside the greenhouse within a certain range by rolling the film. Therefore, double arch and double film greenhouses in northern China mainly serve as insulation cultivation for early spring and delayed autumn. Generally, they can be advanced by 30-35 days in spring and delayed by 20-25 days in autumn, but cannot be used for overwintering cultivation; In the southern region of China, double arch double film greenhouses are not only used for insulation and winter cultivation of vegetables and flowers in winter and spring seasons, but also can replace shading nets for facilities such as shading and cooling in summer and autumn seasons, as well as rain, wind, and hail prevention cultivation.
