Film greenhouse

The plastic greenhouse makes full use of solar energy, has a certain thermal insulation effect, and can adjust the temperature and humidity in the shed within a certain range through film rolling. Therefore, in northern China, plastic greenhouse mainly plays the role of thermal insulation cultivation in advance of spring and delayed in autumn. Generally, it can be 30-35 days in advance in spring and 20-25 days in autumn, but overwintering cultivation cannot be carried out; In southern China, plastic greenhouses can not only be used for heat preservation and overwintering cultivation of vegetables and flowers in winter and spring, but also replace shading nets for shading and cooling in summer and autumn and protected cultivation against rain, wind and hail.
