新疆戈壁地区典型日光温室冬季环境性能研究

Study on Winter Thermal Environment of Typical Solar-greenhouse in Gobi Region of Xinjiang

以新疆南疆戈壁地区典型砖墙温室和戈壁石墙日光温室为研究对象,比较了2种日光温室的冬季生产环境及墙体热通量,以期为南疆地区日光温室的管理、维护及新建提供理论依据。结果表明:戈壁石墙温室晴天升温更快,不揭帘时,白昼最高气温比砖墙温室高8℃以上;2种墙体白天蓄热性能相近,而夜间戈壁石墙的放热效果优于砖墙。但是,由于温室构造差异及管理水平较低,导致戈壁石墙温室内夜间最低空气温度与土壤温度,均显著低于砖墙温室,甚至出现了0℃以下的情况。说明该温室保温性能及管理水平有待于进一步提高。

Taking two solar-greenhouses which with typical brick-wall and Gobi stone walls in Gobi Region of South Xinjiang as research object,winter production environment and wall heat flux were studied on two solar-greenhouses, inorder to provide theoretical basis to manegement, maitainance and new construction of solar-greenhouse in Gobi Region of South Xinjiang. The results showed that the greenhouse of Gohi stone wall warmed up faster in the sunny day, and without ventilation,the inner highest temperature could be 8℃ higher than it in brick wall. Meanwhile the test of wall heat flow showed such two kinds of wail shared a similar heat storage capacity in the day time while the exothermic effect of Gobi stone wall was better in the night. However, due to the reason of structure differences and bad management, both the air and soil temperature of Gobi Stone wall greenhouse were significantly lower than brick walls greenhouse,even below 0℃ in the night. It was clear that the greenhouse insulation performance and management levels should be further improved.
