研究分析3种不同密度槟榔园间作对成龄香草兰叶绿素荧光参数的影响。结果表明，在一定范围内，香草兰PSII的潜在活性（Fv／Fo）和表观光合电子传递速率（ETR）随着槟榔密度的降低而显著降低；同时，最大光化学量子产量（Fv／Fm）、实际光化学效率（Yield）和光化学淬灭系数（gP）都呈下降趋势；低密度槟榔园间作条件下．香草兰的天线转化效率（FU＇/FM＇）最低。表明高密度槟榔（株行距为2．0m×2．5m）条件较适合问作香草兰，在生产中可以应用。

Effects of three different intercropping densities of areca on chlorophyll fluorescence characteristics of grown vanilla was investigated. The results showed that potential photochemical efficiency (Fv/Fo) and electron transport rat (ETR) were decreased evidently while the areca densities were falling in a certain range; Meanwhile, maximum photochemical efficiency (Fv/Fm), effective quantum yield of photosystem II (Yield) and photochemical quenching coefficient (qP) all showed a downward trend. In addition, efficiency of excitation captured by open PSII center(Fv'/Fm') was the lowest when areca density was bottommost. These results showed 2.0 m × 2.5 m spacing of areca was suitable for vanilla growth.
