Abstract：In order to choose reasonable material and structure for the back wall of solar greenhouse,dif-ferent walls,such as normal hollow brick wall,complex heterogeneous wall,and blockboard wall,were used to construct solar greenhouse in Suining and Ganyu County in 2012.And their warming and thermal insulation properties were studied.The results showed that the normal hollow brick wall had strong heat storage capacity, which existed good thermal insulation effect during the night,but it warmed up slowly during the day.The blockboard wall had bigger thermal resistance value and warmed up quickly during the day,which could boost the highest temperature in solar greenhouse,but it had low exothermal capacity,which existed poor thermal insulation effect during the night.The complex heterogeneous wall had good thermal resistance and heat stor-age capacities,which had the best warming and thermal insulation property.In order to obtain better warming and thermal insulation effects in winter and save cost,the wall with 1 cm inner calcimine,24 cm hollow brick,24 cm hollow brick,10 cm protection layer which was made of polystyrene foam board and 1 cm outer calcimine was the best choice.
