This paper studied temperature change and heat-absorbing volume change of greenhouse soil in slope ground greenhouse during the day with flat ground greenhouse as a control to provide a reference for the renovation of the old solar greenhouse.The results showed that the slope ground greenhouse significantly improved the soil temperature environment of the solar greenhouse.Compared with the flat ground greenhouse,the soil temperature increased by 0.1-1.7 ℃,the highest soil temperature by 1.0-1.9 ℃,the air temperature above corp canopies was reduced by 1.9-4.0 ℃,and heat-absorbing volume of the soil increased by 8.44％-44.57％.The increase of soil temperature and heat-absorbing volume on sunny days was greater than on cloudy days.
