Abstract: To investigate the variation of the temperature in winter and spring inside sunlight greenhouse in Cixi, and to appropriately adjust the solar greenhouse temperature as well as to increase the crop yield and quality, the author analyzed the solar greenhouse inside and outside temperature with different weather types based on the collected data of single standard plastic solar greenhouse in agriculture base of bureau of meteorology in Cixi, Zhejiang. The results showed that: (1) Cixi solar greenhouse indoor average daily temperature was higher than that of the outdoor, the overall trend of greenhouse inside and outside temperatures was same, the daily changes of greenhouse internal and external air temperature were affected by the solar radiation; (2) Type of indoor temperature diurnal variation of different weather types showed an unimodal daytime temperatures change speed, the overall air temperature change followed sunny>clouds>cloudy>rainy, and the nigh temperature change was stable at different weather types; (3) The relationship between indoor and outdoor air temperature was notable, and the correlation was as rainy day>cloudy>cloudy>sunny.The results showed that: (1) Cixi solar greenhouse indoor average daily temperature is higher than that of the outdoor, the overall trend of greenhouse inside and outside temperatures is same, the daily changes of greenhouse internal and external air temperature were affected by the solar radiation ; (2) type of indoor temperature diurnal variation of different weather types showed a unimodal daytime temperatures change speed, the overall air temperature change followed sunny> Clouds> cloudy> rainy, and the nigh temperature change is stable at different weather types; (3) The relationship between indoor and outdoor air temperature is notable, and the correlation is as rainy day>cloudy>cloudy >sunny.
