Abstract:
Temperature，humidity，illumination and CO2 of glass greenhouse with butterfly-like windows and plastic greenhouse with serrated windows were compared and analyzed through monitoring method by multipoint sensor,in order to provide basis for big data analysis and modeling of greenhouse structure design.The results showed that，the indoor temperature was higher than the outdoor，the humidity was lower than the outdoor，and the change trend was the same.In the vertical direction，the uniformity of temperature and humidity distribution in glass greenhouse was poor；the room was in a weak light environment.The daylighting performance of glass greenhouse was better than that of plastic greenhouse，but the uniformity of light distribution was poor；the CO2 consumption of crop canopy was high in daytime.
