【摘要】 以西宁市城北郊区日光节能温室内外为观测点,采用同步平行观测及对比分析的方法,研究了不同天气条件对温室内外光照强度及温湿度日变化的影响。结果表明:温室内外光照强度和温度日变化晴天最大,雪天次之,阴天最小;温室内、外平均温度以阴天最高,雪天和晴天次之,雪天室内增温最明显;温室内外相对湿度日变化幅度依次为晴天>阴天>雪天。更多还原

【Abstract】 Test point that inside or outside the solar greenhouse in the northern suburb of Xining city as research objects,the light intensity,temperature and humidity were studied under the different climatic conditions by method of synchronous parallel observation and contrastive analysis.The results indicated that the light intensity and the daily temperature changes were the most different when it was sunny but the change differed least when it was cloudy,and the change was intermediate when snow days.The average temperature inside or outside the greenhouse was the highest when it was cloudy and then snow and sunny days.The temperature increasement was the most obvious when snow days inside the greenhouse;the ranges of daily relative humidity inside or outside the greenhouse were the largest when sunny days,then cloudy days and snow days in turn.更多还原
