摘　　要：通过测定五味子各种采光结构表面的光照强度和单位土地面积光利用率的日变化和月变化,以确定五味子生产的合理采光结构,提高产量。结果表明:不同采光结构平均光照强度顺序为:30°斜架(64.2 klx)>45°斜架(53.8 klx)>南北架(49.5 klx)>东西架(38.8 klx),30°斜架的光照强度分别比南北架高29.7%,比东西架高65.5%;光利用率的顺序为:斜架(100%)>南北架(39.3%)>东西架(24.3%),斜架的光利用率分别是南北架的2.5倍,东西架的4.0倍。栽培五味子宜采用斜架。In order to determinate scientific light structure for the increase of the yield,the change of light intensity on the surface of different shelves and light availability on the surface of land were determined.The results showed that the light intensity sequence of different shelves as follow：30°oblique shelf（64.1 klx）45°oblique shelf（53.8 klx）south-north erect shelf（49.5 klx）east-west erect shelf（38.8 klx）,the light intensity of 30°oblique shelf was 29.7% higher than the south-north,65.5% higher than the east-west.The light utilization efficiency sequence was oblique shelf（100%）south-north shelf（39.3%）east-west shelf（24.3%）,the light utilization efficiency of 30°oblique shelf was 2.5 times and 4.0 times as that of the south-north and the east-west respectively.The oblique shelves should be adopted.
