Abstract:

通过模拟实验,研究凤眼莲不同苗龄根系分泌氧及有机碳的规律,在此基础上分析凤眼莲根系分泌氧和有机碳对富营养化水体溶解氧、有机碳及无机氮(NH4+和NO3-)转化的影响。研究结果表明凤眼莲根系具有较强的泌氧及分泌有机碳的能力,小、中、大三个苗龄凤眼莲根系泌氧速率分别达56.19、93.15、106.32μmolO2·h-1,根系分泌有机碳的速率分别达0.25、0.60、0.92mg·L-1·h-1.不同苗龄凤眼莲根系泌氧及有机碳的速率随苗龄的增加显着升高,而其相对应的单位根系泌氧和有机碳的能力随苗龄的增加呈降低趋势。水体中无机氮的去除率随着凤眼莲苗龄的增加而增加,这除了与凤眼莲的吸收作用有关外,还因为其泌氧和分泌有机碳的总量增加加强了硝化和硝化-反硝化过程的潜力,从而高效并快速地净化水体中外源氮负荷。
