为解决冬季植物问题,将4种木本植物引入潜流人工湿地环境,进行植物适应性和去污效果研究,结果表明:(1)4种木本植物在潜流人工湿地环境下的净光合速率日变化规律为夹竹桃、栀子、女贞变化规律是“双峰”型,木槿则是“单峰”型;叶片气孔导度日变化规律为木槿是“单峰”型,其他3个品种没有明显规律;植物胞间CO_2浓度的日变化规律与净光合速率日变化规律相反对应关系;蒸腾速率日变化规律为4种植物都呈现“单峰”型规律,且高峰出现在11:00—13:00之间。(2)除女贞外较低外,其余3种植物叶绿素含量较高但差异不大;丙二醛含量较高的是木槿与栀子,女真最低;氮磷积累量最高是夹竹桃,最低的是木槿;基质脲酶活...

To solve the problem of plant dieback over winter, four kinds of woody plants have been applied to constructed wetland and a series of physiological and biochemical indicators have been measured to analyze the adaptability and decontamination capability of the plants. The results showed that: (1) The diurnal variation of the net photosynthetic rate of oleander, gardenia and privet was of a "Twin Peaks" type, while the hibiscus was "unimodal" type; the diurnal variation of the leaves stomatal conductance of hibiscus was of "unimodal" type while the other three varieties showed no obvious trend....
