| 摘要: |
| 以 马 尾 松（Pinus massoniana） 与 乡 土 树 种 黧 蒴（Castanopsis fissa）、 红 锥（Castanopsis
hystrix）、枫香（Liquidambar formosana）、荷木（Schima superba）和假苹婆（Sterculia lanceolata）为研
究对象设计混交盆栽试验，研究叶片光合和全株光合特征参数的差异。结果表明：枫香对马尾松、黧蒴
的光合作用有一定的促进作用，各树种的光合能力基本表现为从对照组到单混种组到双混种组依次上升
的变化趋势。双混种组合的实际光合能力相比理论值平均提高 15.62%。马尾松 + 黧蒴 + 枫香组合的光合
作用提升程度最大，是本次试验的最佳组合。 |

| Abstract: |
| In order to provide a suitable hybrid combination, Pinus massoniana was chosen as the main specie
to study the influence of hybrid and was designed to grow respectively with Castanopsis fissa, Castanopsis hystrix,
Liquidambar formosana, Schima superba, and Sterculia lanceolata. The data included several photosynthetic
characteristics and the total absorption value of CO2 of whole plant and the result showed that Liquidambar
formosana has a distinct effect on the growth of Pinus massoniana and Castanopsis fissa. All species generally
followed the pattern that the value of double mixed group was greater than single group, than CK group. Compared
with theoretical value, the actual photosynthesis increasing rate was up to 15.62% on average for double mixed
groups. Photosynthesis ability of squad of Pinus massoniana& Castanopsis fissa& Liquidambar formosana
increased the most, which was considered as the fittest combination for Pinus massoniana stand transformation. |
