徐州地区日光温室保温性能的试验研究

分析了徐州地区冬季日光温室小气候的变化规律。针对当地日光温室冬季保温性能不理想的现状，从光照条件和温度条件两方面进行分析，对温室自身造成的保温性能不理想提出了改进意见，并在现有温室结构的基础上，通过选择最佳的揭盖帘时间，来提高冬季日光温室的保温性能。揭盖帘对比试验表明，揭盖帘时间选取恰当对室内温度影响较大，可以提高温室的保温性能。

Research on Heat Preservation of Solar Greenhouse in Xuzhou

The microclimatic change laws of the solar greenhouse in winter of Xuzhou area have been analyzed in this paper. To change the current situation with unsatisfactory warm performance in winter, the author analyzes from illumination condition and temperature condition, and proposes the suggestion improving the warm performance caused by greenhouse itself. On the basis of constant structure of greenhouses, the warm performance of the solar greenhouse in winter can be improved by choosing the optimal time of taking off and covering the curtain. The comparison experiment of taking off and covering the curtain shows that choosing the appropriate time can improve the warm performance.
