Abstract: Adopted microclimate automatic monitoring equipment to observe of thick wall temperature combined with the data from outdoor weather station temperature observation during this period, temperature change characteristics and temperature change characteristics of continuous cloudy conditions of the autumn, winter and spring seasons sunny,cloudy,overcast weather conditions were analyzed.The results showed that diurnal variation of temperature in different weather conditions of different seasons was basically consistent in the greenhouse, and temperature showed single wave.All the extreme maximum and minimum temperature appear in sunny day.The change of temperature was consistent in and outside the greenhouse in different seasons, and the temperature is much higher in the greenhouse.During the continuous cloudy days,the temperature in the greenhouse gradually decreased, and the temperature difference reduced.
