Greenhouse ventilation management: Spring outlet size can not be completely defined by a particular data, because the structure of the greenhouse greenhouses offer different monomers, cooling time and speed is different. Camber larger greenhouses, because camber surface suitable monomer shed built shed, hot air is easily discharged along the upper specification monomer greenhouses greenhouse films, even leaked a small mouth, but also to achieve better results leaked. And the longer the low planting years old shed, because greenhouse camber smaller monomer greenhouses, sheds surface is relatively flat, hot air shed leaked discharge port speed from slow, shed the temperature is high. Typically, this will be at the top of the greenhouse leaked mouth open to 40 cm wide, only with a higher altitude, camber larger greenhouses open to the same outlet 30 cm leaked effect. The main types of greenhouses: toward choice. That shed shed shed toward the north and south sides of the head, respectively, to engage in the cultivation of greenhouse recommended to choose from north to south. This orientation allows the crop canopy to the uniform distribution of light. Greenhouse wall material as long as good thermal insulation and heat storage capacity of the data may be employed. The emphasis here must have a regenerative function interior greenhouse, greenhouse masonry to local conditions.
