【摘要】采用围隔系统研究了陆生植物黑麦草(Lolium multiflorum)对畜禽养殖富营养水体中主要营养元素磷的净化效应及动态过程.结果表明:浮床黑麦草在富营养化水体中生长良好,对富营养水体中的总磷具有明显的净化效果.当覆盖率为30%时,对总磷的去除率最高达到72.96%.对其去除水体总磷的动态过程拟合表明符合三次方程曲线.实验结果为陆生植物修复富营养水体的季节模式和机理的深入研究提供了科学依据.更多还原

【Abstract】 The purification effect and dynamics processes of Lolium multiflorum on floating bed in enclosure for removing main nutrient TP in eutrophic water body were studied.The results showed that Lolium multiflorum could grow well and effectively remove TP in eutrophic water body.The removal efficiency of TP in water reached 72.96% when the floating bed coverage ratio was 30%.The fitting method of dynamics processes of removing main nutrient TP by Lolium multiflorum showed that it accords with cubic curve.It provided the scientific basis for studying on season pattern and mechanism of terrestrial plant to purify eutrophic water body.更多还原
