| 摘 要： | 以香樟(Cinnamomum cam phora)为试验材料,通过模拟氮沉降的方法,研究了不同氮沉降条件下香樟叶片的光合、叶绿素荧光生理的表现,揭示了相应的生理生态机制.结果表明,适当浓度的氮沉降对香樟的生长具有促进作用,而过量的氮沉降会降低其净光合速率,从而对其生长产生抑制作用；不同处理组香樟的光补偿点(LCP)、光...

| Abstract: | The simulated nitrogen deposition experiment was conducted on Cinnamomum camphora to investigate the photosynthesis and chlorophyll fluorescence of Cinnamomum camphora under different nitrogen treatment.The results showed that the proper nitrogen deposition had positive effect on Cinnamomum camphora growth,while the excessive nitrogen supply would decrease the photosynthetic rate and further inhibited the Cinnamomum camphora growth.The light compensation point(LCP) and light saturation point(LSP) of differe... |
