以甘肃省西北XB-GⅡ日光温室为研究对象,对其微气候环境因子,如室内外温度、墙体和地面不同深度温度、墙体和地面热流量、室内外光照强度等进行了测定和分析。结果表明:这种西北型日光温室冬季室内外最低温度差可达32℃,晴天温室内温度保持在20℃以上时间达到6h以上,冬季30cm深地温和墙体内侧30cm处基本达到日夜恒定,从热通量变化分析,土壤是温室最主要的放热体,墙体次之。温室管理白天需注重通风降温,而晚间则需加强保温覆盖。
Taking the XB-GⅡ solar greenhouse in northwestern Gansu Province as the research object, the microclimate environmental factors such as indoor and outdoor temperature, different depth of wall and ground, heat flow of wall and ground, indoor and outdoor light intensity were measured and analyzed . The results showed that the minimum temperature difference between winter and winter in northwest type solar greenhouse was 32 ℃, the temperature in sunny greenhouse was above 20 ℃ for more than 6h, and the depth was 30cm in winter. Analysis of heat flux changes, the soil is the most important greenhouse heat extinction, followed by the wall. Greenhouse management during the day should pay attention to ventilation and cooling, while in the evening you need to strengthen the insulation cover.
