摘　　要：为得出园林照明对园林植物光合指标的影响,对园林植物窄叶石楠(Photiniaserrulata)进行5种不同光谱的发光二极管(LED)照射,每种光谱设置3级光照强度,并测量植物净光合速率及植物光合有效辐射.结果表明:相同光照强度,天然光照下植物的光合有效辐射最高;人工光源照射下,窄叶石楠净光合速率随光照强度升高而升高;绿光LED(530nm)照射,植物的光合有效辐射随光照强度增高,但净光合速率始终为负.To clarify the impacts of artificial light spectrum and illumination intensity on the photosynthetic indices of landscaping plants,spectral irradiation experiments were conducted on Photinia serrulata at three light intensities with five different light emitting diode（LED）light emitting cliode.Analysis of the relationship of artificial light spectrum,light intensity,the net photosynthetic rate and photosynthetic active radiation.Results showed that：At the same light intensity,photosynthetically active radiation of plant was the highest under sunlight,which was far higher than that under the LED light sources.Under LED lights,net photosynthetic rate of Photinia serrulata rose with enhancing light intensity.Under green LED light（530 nm）,photosynthetically active radiation of plant increased with enhancing light intensity.However,net photosynthetic rate remained negative all along.
