Abstract: Based on meteorological observations in the energy-saving heliogreenhouse in Ping’an, Qinghai Province from June 2010 to August 2011, the author studied the temperature inside the greenhouse variation law under different weather conditions and the correlation between the temperature inside the greenhouse and the temperature outside the greenhouse. The results showed that: (1) the daily variation of air temperature around the year inside the greenhouse was unimodal. The temperature of air in day was higher than that at night, and the temperature of air inside the greenhouse was higher than that outside, whatever the weather condition. (2) The daily variation of the air temperature inside the greenhouse changed with different seasons and different weather conditions, for the obvious difference with the time of maximum and minimum evapotranspiration and temperature variation inside the greenhouse and outside. (3) Inside and outside the greenhouse the air temperature were positively correlated, and the correlation was stronger at night than that in day. Regression equations based on this correlation were of significance at agricultural weather forecast.
