Abstract:
Five different wall structures or insulation methods in a non-warmed mainstream solar greenhouse at the same location were carried as material，which named thick wall single membrane double insulation(w1)，thick wall double membrane internal insulation(w2)，thick wall single membrane internal insulation(w3)，37 cm wall single membrane double insulation(w4)，machine built wall single membrane insulation(w5)，the air temperature indoor and the temperature of back wall were measured and analyzed.The results showed that the thick wall w1 with double-layer thermal insulation blanket was the best thermal insulation effect，and the difference with w2，w3 and w4 was significant；while w4 had the same covering but the wall was 37 wall had the worst thermal insulation effect.The reasonable thickness of the back wall was 0.8-1.0 m，and the inner 0-0.4 m area of the back wall was the main storage and release layer.The material with larger specific heat capacity should be selected，and the 0.4-1.0 m area mainly played the role of heat insulation.Therefore，the thickness of the back wall of the solar greenhouse should be 0.8-1.0 m and the material with larger specific heat capacity should be filled inside.Therefore，the thickness of the back wall of the solar greenhouse should be 0.8-1.0 m and the material with larger specific heat capacity should be filled inside.The front roof with external thermal insulation cover could effectively improve the heat preservation effect of the greenhouse.In Baotou and surrounding areas，the fruit vegetables could be safely produced in winter greenhous without heating.
