摘　　要：日光温室昼夜温差大,北墙作为主要蓄热体对温室夜间温度调节具有重要影响。冬季凌晨时段日光温室内空气温度较低,对作物生长不利,针对这一现象本文提出在日光温室北墙内侧使用＂热阻帘＂以延迟墙体热量释放的时间、从而提高凌晨低温时段室内空气温度的方法。通过在北京地区冬季的试验证明,夜间热阻帘覆盖墙体内表面时（晴天16∶00-4∶00,阴天16∶00-3∶00）试验温室墙体内表面热通量比对照温室分别减小38.5%、38.9%,热阻帘卷起后的时段内（晴天4∶00-8∶30,阴天3∶00-8∶30）墙体内表面热通量比对照温室分别增大7.2%、13.5%,在此低温时段内试验温室跨中空气温度比对照温室高0.28~0.32℃。The north wall is a significant thermal storage structure in Chinese Solar Greenhouse,which could adjust indoor temperature.Low temperature during early morning in the greenhouse could prevent plants growth.So an effective method to increase indoor temperature in early morning was put forward in the study.Heat isolation curtain could adjust the wall＇s thermal flux.The practice in Beijing showed that the curtain covered on the north wall（sunny 16∶00-4∶00,cloudy 16∶00-3∶00） prevented 38.5% heat releasing in sunny day and 38.9% in cloudy day.After curtain taken off（sunny 4∶00-8∶30,cloudy 3∶00-8∶30）,the amount of heat flux was 7.2% higher than CK greenhouse in sunny day and 13.5% in cloudy day,which meant the indoor temperature was 0.28~0.32℃ higher than CK greenhouse during whole early morning.
