应用数学模型分析了温室方位、连栋数、季节及地理纬度对太阳直射光透过率的影响。在低纬度地区,上述各要素(除纬度外)对温室直射光透过率的影响效果均显著小于高纬度地区。然而,就东西栋温室而言,其栽培床面上的光照分布在高纬度地区和低纬度地区都表现出不均一性特点。 The mathematical model was used to analyze the effects of the greenhouse orientation, the number of continuous fronts, the seasonal and geographical latitudes on the direct solar transmittance. In low latitudes, all the above factors (except latitude) have less effect on direct light transmittance in greenhouse than in high latitudes. However, in the case of East and West Greenhouse, the light distribution on the cultivation bed shows heterogeneity in both high latitudes and low latitudes.
