摘　　要：珍稀植物白花油麻藤（Mucuna birdwoodiana Tutch）是豆科（Leguminosae）黧豆属（Mucuna）常绿、大型木质藤本植物，具有重要园林绿化价值。对其生态生物学特征研究表明，白花油麻藤适合生长在热带和亚热带地区；光合速率日进程呈“双峰”曲线，有明显的“午休”现象。植株体内加权平均养分含量较低，叶片所含的养分较多，植物体钾和磷元素含量偏低，在其生长过程中应适当及时地补充其生长必需的氮、磷、钾等矿质营养元素，以维持植株生长所需的养分平衡。利用白花油麻藤在城市绿化等实际应用中，需考虑其生态生物学特征。Mucuna birdwoodiana is a evergreen vine species with great potential in landscape greening. The studies on the ecological, biological and physiological characteristics showed that M. birdwoodiana was suitable to be planted in tropical and subtropical areas for its low cold resistant capability. The diurnal course of photosynthesis of M. birdwoodiana exhibited a ＂double-peak＂ curve with remarkable midday depression. The weighted nutrient concentration of the plant was lower with leaves relatively higher amount of nutrient compared to other organs. The concentration of potassium （K） and phosphorus （P） in the plant was relatively lower, so the mineral nutrition essential to the growth of M. birdwoodiana should be added to improve the growth status. Thus all the biological characteristics ofM. birdwoodiana should be considered in order to exploit and utilize it widely in landscape greening.
