摘　　要：为了探究传统土墙、土＋聚苯板墙体、全聚苯板轻质墙体对日光温室保温效果的影响,对应用3种不同保温墙体日光温室的室内热环境进行了对比试验。结果表明,3种天气情况下,白天8：00-12：00,土＋聚苯板温室的室内气温均高于土墙温室和全轻质聚苯板温室,平均高1.4℃和2.3℃;夜间土墙温室的保温效果最好,土＋聚苯板温室的保温效果仅次于土墙温室,其室内气温比土墙温室室内气温平均低0.5℃,但比全轻质聚苯板温室室内气温平均高1.6℃。土＋聚苯板墙体温室白天和夜间的保温蓄热效果在这3种墙体温室中相对较好,在温室墙体改造过程中,可以采取性价比较高的此种温室。In order to explore the influences of traditional wall, soil ＋ polystyrene board wall and polystyrene lightweight wall on the heat insulation effects of solar greenhouse, the contrast tests of indoor thermal environment in solar greenhouse were carried out. The results showed that,under three different kinds of weather conditions, during the day 8：00-12：00,the indoor temperature of soil＋polystyrene board greenhouse was higher than the soil wall greenhouse and the polystyrene board green- house,and the average temperature was higher 1.4 ℃ and 2.3℃ ;during the night, the heat insulation effect of soil wall greenhouse was the best,which of the soil＋polystyrene board wall greenhouse was behind the soil wall. The indoor temperature in the soil＋polystyrene board wall greenhouse was lower than the soil wall greenhouse＇s about 0.5 ℃,but it was higher than polystyrene lightweight wall about 1.6 ℃. Soil＋polystyrene wall greenhouse had a better thermal insulation thermal effect in these three greenhouses during day time and night time ,then this cost-effective greenhouse could be used for the greenhouse wall renovation in the future.
