摘要/Abstract

摘要： 通过水面浮岛栽培试验，研究了鄂水芹一号植株的生长特征、植物量的分布结构，及其在富营养化水体中对氮、磷的吸收情况。研究成果如下：水芹植株的平均鲜量35.22 g，其中水上部分占77%，水下部分占23%，生物量分布主要集中在水上部分；其对N，P的直接吸收分别可以达到13.05～33.14 kg/(hm2·a)和5.62～6.67 kg/(hm2·a)。结果表明，水芹是一种适合在低温的情况下进行水培的植物，并对富营养化水体有良好的净化效果。

Abstract: Experiments on oenanthe javanicas planted in floating-beds were conducted to study distribution of biomass and absorbing contents of N and P from eutrophic water body. The average fresh weight was 35.22 g per plant, with the above-water part counted 77% and the under-water part 23%. The waterborne part played a key role in the biomass structure. The directly absorbing contents of N and P were 13.05-33.14 kg/(hm2·a) and ?5.62-6.67 kg/(hm2·a), respectively. The results showed that the oenanthe javanica grows well under the lower temperature and is good for water purification on the eutrophic water body.
