红花檵木的光合生理特性及其在园林中的应用研究

Photosynthetic Character of Loropetalum chinense and Its Application in the Landscape and Architecture

植物的光合生理特性对其园林应用有着相当重要的指导作用,在调查和测定的基础上对红花檵木的光合特性进行了总结和测定。结果表明：红花檵木的光补偿点为30.37μmol.m-2.s-1,光饱和点为907.20μmol.m-2.s-1,最大光合速率为10.84μmol.m-2.s-1,呼吸速率为3.12μmol.m-2.s-1,CO2补偿点为76.69μmol.m-2.s-1,CO2饱和点为504.95μmol.m-2.s-1。根据其光合生理特性,确定其在园林中的应用形式主要作为色块、灌木球、色篱、园林小品、大型桩景、隔离带等。

It is very important of physiological characteristics of plants to guide application of landscape and architecture.In the paper,we had investigated physiological characteristics of Loropetalum chinense var.rubrum,the results showed that its light compensation piont was 30.37μmol·m-2·s-1,light saturation point was 907.20μmol·m-2·s-1,the maximal photosynthetic rate was 10.84μmol·m-2·s-1,the respiration rate was 3.12μmol·m-2·s-1.Its CO2 compensation point was 76.69μmol·m-2·s-1,CO2 saturation point was 504.95μmol·m-2·s-1.Based on the physiological characteristics,we had determined that the plant can be application as color brock,spherical shrub,color fence,garden ornaments,large piles and belt planting in landscape and architecture.
