Abstract:

In order to choose reasonably materials and structures of the back wall of greenhouse, an experiment with a different configuration of the back wall of greenhouse simulation test was carried out from November 1, 2010 to March 6, 2011 in Xiqing District. There were 3 different thicknesses of walls and 3 different interior walls with brick which had 6 different kinds of treatments in simulation test. The results showed that: the back wall was heat source under different weather conditions. The mud wall which the thickness was 1.5 m could not guarantee the safety of the vegetable production. If the day was cold the temperature would be harmful for the vegetable. If it made the greenhouse obtain a higher temperature in winter and saved costs the back wall of greenhouse with 37 cm brick and 12 cm protection layer which was made with polystyrene foam board was the best choice.
