Abstract: The microclimate factors of in inside and outside greenhouse were observed to know civil wall greenhouse microclimate variation and improve facilities for agricultural meteorological service levels. The temperature, moisture, ground temperature and solar radiation in inside and outside greenhouse and inside model prediction were observed by using correlation analysis and stepwise regression method. The results showed that: (1) indoor temperature, humidity, soil temperature had obvious diurnal variation in summer and winter, and the greenhouse warming was higher in winter than in summer, which confirmed that greenhouse construction wall had a good thermal insulation effect; (2) with the depth increasing of soil layer, the soil temperature was decreased at 5 cm, 10 cm and 20 cm, and the peak value of soil temperature was lag 1 hour with the increasing of soil layer; (3) a positive relationship was found between greenhouse indoor temperature and indoor microclimate factors. The absolute error value of indoor temperature prediction was less than 1 ℃ in summer and winter and relative error was less than 10% by established indoor temperature prediction model in summer and winter.
