| 摘 要： | 选取美人蕉、风车草、菖蒲和香根草4种常见的浮床植物为研究对象,对其生长特性及吸收氮磷的能力进行比较研究.结果显示,4种植物的成活率均在90%以上,移栽后60-100d为植物的快速生长期.经过4个月的生长.4种植物水面上部生物量均明显高于下部;除香根草外,其它3种植物体内的氮磷含量均呈叶>根>茎的分布;植物体内的氮、磷累积量大小依次为美人蕉>风车草>菖蒲>香根草.植物吸收占浮床系统氮去除的比例均低于40%,占浮床系统磷去除的比例均高于55%.4种植物中,美人蕉对水体中氮磷的吸收能力最强,可以将其作为三峡库区次级河流的浮床栽培植物进行推广.

| Abstract: | Taking Canna indica, Cyperus alternifolius, Acorus calamus Linn and Vetiveria zizanioiaes as research subjects, the characteristics and nutrient uptake abilities of these four familiar plants cultivated on a floating-bed were compared. The survival rates of the four plants were more than 90%. The rapid growth period was from sixty days to one hundred days after planting. After four months, the above-water biomass of the four kinds of plants was greater than the underwater biomass. Except for Vetiver zizanio... |
