摘要
为提高杨树人工林的产量,探索不同氮素浓度水平对杨树光合生产力的影响,本文以蛭石培养模拟氮素胁迫的实验方法,设置4种氮素浓度水平(缺氮、低氮、CK、高氮),测定分析了杨树扦插生根植株叶片光合气体交换参数、叶绿素荧光参数及生物量,探讨不同氮素浓度水平对杨树光合作用影响程度与机理。结果表明:氮素能明显改变杨树的光合生产力,表现为随着氮素浓度水平的升高,杨树叶片净光合速率(P_n)、最大光合速率(P_(nmax))、光合量子效率(Φ)、PSII最大和实际光化学效率(F_v/F_m和Φ_(PSII))、总生物量等明显上升。氮素影响杨树幼苗的地上地下部分的分配格局,表现为随着氮素浓度的升高,叶生物量比(LMR)升高,根生物量比(RMR)下降。供氮不足时,引起杨树光合作用下降的原因,主要是由PSII反应中心的电子传递受阻的非气孔因素造成的。将杨树用于人工林连作栽培时,建议增加氮肥的使用量,最适用氮量还需要进一步研究。
To explore effect of different nitrogen concentration on photosynthetic productivity of poplar and improve poplar plantation production,the poplar seedlings in this experiment were conducted in planting pot and planted by vermiculite to simulate nitrogen stress.Four nitrogen concentration(deficiency-nitrogen,lownitrogen,CK,high-nitrogen) were set for the measurement and analysis of gas-exchange parameters,Chl fluorescence parameters and biomass of poplar cutting rooting plant leaves.The influence degree and mechanism of different nitrogen concentration to poplar photosynthetic was explored in this paper.The result shows that nitrogen changed photosynthetic productivity,which mainly manifested as the following:with an increase in N supply,net photosynthetic rate(P_n),maximum photosynthetic rate(P_(nmax)),photosynthetic quantum efficiency(Φ),maximal and effective quantum yield of PSII photochemistry(F_v/F_m and Φ_(PSII)) and total biomass etc.were up significantly.The distribution pattern of biomass above groundand the underground biomass was effected by the nitrogen which mainly manifested as leaf mass ratio and root mass ratio incresed with increasing N concentration.N supply had significant effect on total nitrogen content of different organs which was presented as total N concentration of leaves and root increased with N supply.At nitrogen lacking,the main reason of decline of poplar photosynthetic was that non stomatal factors of the electron transfer of PSII was restrained.We suggest increasing application of nitrogen when poplar are planted as plantation recurrent cultivation.The optimum amount needs further study.
