富营养化水体中盐度对香蒲去除氮磷作用的影响
Effects of salinity on removal of nitrogen and phosphorus from eutrophic water using Typha angustifolia L
摘要
Abstract
The effects of salinity on the removal of nitrogen and phosphorus from eutrophic water using barrel-planted Typha angustifolia L. were studied. The results show that, when the salinity ranged from 0 to 1. 00%, Typha angustifolia L. could remove nitrogen and phosphorus from eutrophic water efficiently and quickly. The removal rates of NH+4-N, TN, and TP significantly decreased with the increase of salinity. With the increase of salinity, the physiological characteristics of Typha angustifolia L. changed. In comparison with the control group, the chlorophyll content in the leaves of the tested Typha angustifolia L. significantly decreased under NaCl stress. With 1. 00% salinity, Typha angustifolia L. could accumulate sufficient proline to achieve osmoregulation. However, the content of malondialdehyde ( MAD) in the leaves of the plants increased significantly and the plasma membrane was damaged. The results of this study indicate that the changes of physiological and biochemical indices of Typha angustifolia L. under NaCl stress are consistent with the removal of nitrogen and phosphorus from eutrophic water.关键词
