摘要：

为了合理地确定日光温室后墙的材料与结构，于2010年11月1日—2011年3月6日在天津市西青区开展了不同墙体构型的日光温室模拟试验，设置了3种不同厚度土墙以及3种不同构型砖墙共6种墙体处理。结果表明：晴天、多云、寡照天气条件下夜间土墙均为热源，对温室保温性有较大贡献，白天土墙为热汇蓄积热量；夹层墙的墙体夜间放热能力较弱，但白天升温较快，利于提高温室的最高温度；土墙厚度为1.5 m的温室不能保障蔬菜生产的安全，该棚型温室易受低温影响；土墙占地较多，且保温性并不比砖墙处理的温室优越，因此不宜选用；为使冬季温室内可获得较高的温度、节约土地和降低建筑成本，建议选择37 cm砖墙+12 cm聚苯乙烯泡沫塑料板保护层为后墙的温室，该后墙温室增温、保温效果均较好。

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.
