摘要
在温室中建立模拟的秋茄湿地系统 ,对照组用人工海水 ,其余组分别用 3种不同浓度的人工污水定时定量对模拟系统进行灌溉 ,持续 1年。结果表明污水影响植物根系的发育 ,胚轴、茎和叶片的形态结构相应发生变化 ,这些变化应该是秋茄幼苗为适应污染物而主动产生的 ,因此其抗污性较强。
A greenhouse experiment was performed for one year to research the effect of wastewater on Kandelia candel seedlings. Artificial seawater was used as the control, three different strengths of artificial wastewater had been discharged into the simulated system in fixed time and quantity. Results showed that the Kandelia candel seedling had a high potential resistance to artificial wastewater by changing its physiological activities and microstructers in all plant organs to adapt the pollutants within wastewater, but the growth of root was restricted with wastewater to some extent.
