摘　　要：对两种不同结构的日光温室进行比较,研究不同天气条件下不同结构类型日光温室温度和太阳总辐射的变化情况,以期为该类型温室的推广利用提供理论依据。具体研究结果如下:1晴天、阴天和雪天,两种日光温室内气温和墙体内表面温度的日变化趋势先下降,后升高,再降低,只是温度的最大值和温度的变化幅度以晴天最大;日光温室内太阳总辐射透过率和太阳高度角的变化相一致,上午逐渐增大,中午13:00达到最大,之后逐渐减小。从两种日光温室的结构、室内温度和太阳总辐射三方面来说,试验温室的采光性能和保温性能最好。2试验温室的内环境特点。连阴天日光温室平均室内气温均不超过11℃,温室内外平均温差较小,这样不利丁作物的生长发育。晴天日光温室内外太阳总辐射存在极显著的正相关关系,可以用y=7.1957e0.0302x的指数曲线关系曲线方程来拟合;日光温室内气温随着太阳辐射的增强而升高,随着太阳辐射的减弱而降低,两者之间呈现极显著的正相关线性关系,可用直线方程y=0.3908x+7.0343描述。The structure of two types solar greenhouse and the changes of temperature and total solar radiation were studied in different solar greenhouses under different weather conditions,wish to provide a theoretical basis for the promotion of the use of such greenhouse. Specific research results were as follows：（ i） Sunny cloudy and snow,the daily variation trend of air temperature and temperature of inner surface of back wall in two solar greenhouses were down first,then rising,fall again,but the maximum temperature and the change range of temperature On sunny day was maximum. Total solar radiation transmittance was consistent with solar altitude,which increased gradually in the morning,13： 00 achieved maximum,then decreased gradually. In terms of structure,air temperature and total solar radiation in greenhouse,performance of lighting and insulation in test solar greenhouse was best.（ ii） Environmental characteristics in test greenhouse showed that mean air temperature in greenhouse during overcast for several days were low and less than 11 ℃,indoor and outdoor temperature difference was small,which was not conducive to crop growth and development. Daily total solar radiation indoor and outdoor had significantly positive correlation which was y = 7. 1957e0. 0302 x,with the increase of total solar radiation,temperature in greenhouse was higher,and vice versa,and there was a significantly positive correlation between them,which could be matched by linear regression equation y = 0. 3908 x ＋ 7. 0343.
