Abstract This research used -40℃ outdoor temperature as designing standards and red brick wall
as the contrast to study the effects of different wall materials on temperature effect of greenhouse．The
results showed that the greenhouse wall structure using 240 mm，20 eyelets perforated brick as interior
wall，120 mm XPS as external wall and 25 mm cement mortar as outermost layer，had higher endothermic
and exothermic capacity，and could raise the soil and air te mperatures effectively.
