【摘要】 采用浮床种植草坪草技术,研究了高羊茅Festuca arundinacea、匍匐翦股颖Agrostis stolonifera2种草坪草对富营养化水体的净化能力。试验结果表明,2种草坪草对富营养化水体中的氮(N)、磷(P)、化学需氧量(CODcr)等具有明显的净化效果,尤其对总磷(TP)的净化能力最强,能有效改善富营养化水体的水质;2种草坪草之间,匍匐翦股颖对TP的去除效果显著高于高羊茅对TP的去除效果。研究结果显示浮床种植草坪草技术可能是一条有效的修复富营养化水域的新途径。更多还原

【Abstract】 The purification effectiveness of tall fescue(Festuca arundinacea) and creeping bentgrass(Agrostis stolonifera) on eutrophicated water was studied by seeding them on floating-beds.The results showed that the two turfgrasses were effective and N,P,COD in the water reduced significantly,especially TP;thus improved water quality.Among twp turfgrasses,creeping bentgrass was more effective on TP than tall fescue.This indicated that seeding turfgrass on floating-bed could be a new way to improve eutrophicated water body.更多还原
