双屋面日光温室建造设计及其环境动态变化分析

Construction design and analysis of environment dynamic changes of double-roof solar greenhouse

为提高有限土地的利用率,在普通日光温室的基础上设计建造双屋面日光温室,对其温度、湿度、光照、CO2浓度等与普通日光温室进行比较。结果表明：双屋面日光温室比普通日光温室土地利用率提高11.90%。双屋面日光温室的南屋面、北屋面在光照强度方面与普通日光温室差异不明显;南屋面日光温室日平均气温比普通日光温室提高0.35℃,而10cm日平均土温则下降0.89℃;北屋面日光温室的日平均气温比当地气温高7.99℃~8.99℃,其10cm日平均土温为8.44℃。双屋面日光温室的相对湿度较普通日光温室变化明显,南屋面日光温室的日平均空气相对湿度相比普通日光温室降低4.43%,北屋面日光温室则升高14.83%;南屋面日光温室日平均CO2浓度相比普通温室降低71.97ppm,北屋面日光温室则升高247.15ppm。

In order to increase land utilization rate,double-roof solar greenhouse was designed and constructed on the basis of the common solar greenhouse;temperature humidity illumination and CO2 concentration were contrasted.The results showed that：compared to common solar greenhouse,land utilization rate of double-roof solar greenhouse increased by 11.90%;the light intensity difference was not obvious both north roof and south roof.The daily average temperature rose to 0.35℃and the 10 cm daily average soil temperature decreased by 0.89℃in south roof.In north roof,the temperature raised by 7.99℃~8.99℃ and 10 cm soil temperature was 8.44℃.Relative humidity in double-roof solar greenhouse changed significantly than common solar greenhouse.The average relative humidity decreased 4.43%in south roof and increased 14.83%in north roof compared to common solar greenhouse.Daily average CO2 concentration decreased 71.97 ppm in south roof and increased 247.15 ppm in north roof compared to common solar greenhouse.
