摘要: 生物修复水体富营养化，尤其是植物和微生物联合修复为目前水体富营养化治理方面的研究热点。不同生育期植物和微生物联合修复鲜见报道。研究不同生育期美人蕉和固定化微生物对富营养化水体的联合修复作用。结果表明，营养生长期和开花期美人蕉-微生物组处理前3天，富营养化水体中不同形态氮和磷浓度快速下降，用于美人蕉生长发育。从富营养化水体氮去除效果来看，营养生长期美人蕉-微生物联合处理去除效果略好于开花期，对磷的去除效果相反。美人蕉吸收氮元素为营养器官利用，其营养器官全氮增长量与生殖器官（花）形成显著差异（PP<0.05）。实验结果表明，不同生育期美人蕉-微生物联合处理对氮和磷的吸收利用存在差异。

Abstract: Bioremediation of eutrophicated water,especially remediation by plants and microbials,has become a hot research area of eutrophication treatment. So far,there have been rarely reported of remediation by different growing phases of plant and microbial. Canna-microbial system,which is composed of Canna-generalis and immobilized microorganism, was utilized to conduct eutrophication reformed experiments that lasted for two growing periods (15 days for each period). The results show that the concentration of every kind of nitrogen and phosphorous descended quickly in the first 3 days of vegetative growing phase and flowering phase affected by cannas,which were vigorously growing through absorbing nutrients and pollutants from the water. The nitrogen's removal during vegetative growing phase showed slightly better than that during flowering phase while the phosphorous' removal showed a counter result. Most of the absorbed nitrogen were assimilated by vegetative organs and the differences of total nitrogen's increment between vegetative organs and reproductive organ(flower) are significant(PP<0.05) with vegetative organs'. The results also showed that there exist some variances between different nutrients' absorption by canna-microbial in different growing phases.
