中文摘要:

采用室外盆栽实验研究了香蒲和梭鱼草两种湿地植物的生长特性及其对富营养化水体中氮、磷的吸收富集能力,为深入研究湿地植物在污水处理中的作用提供依据.实验期间,香蒲和梭鱼草均能在富营养化水体中正常生长,经过5个月的生长,两种植物的总生物量分别为6.65 kg/m2和10.83 kg/m2,约为栽种前的6倍和7倍.实验前,香蒲和梭鱼草根、茎、叶中TN的分布为叶＞根＞茎；TP在两种湿地植物组织中的分布均为叶＞茎＞根.实验结束后,香蒲和梭鱼草各组织中的TN、TP含量均明显下降,TN在梭鱼草组织中的分布仍为叶＞根＞茎,而香蒲组织中TN分布为根＞叶＞茎；两种植物组织中的TP分布为根＞叶＞茎.比较而言,梭鱼草具有较高的氮、磷积累量.

英文摘要:

In order to provide evidence for further study of the role of wetland plant in wastewater treatment,outdoor pot experiments were conducted to investigate two hydrophytes growth characteristics and accumulating ability of nitrogen and phosphorus in eutrophic water.Both of the two species of plants could grow normally in eutrophic water during the experiment period,after 5 months' growth,the total biomass of typha orientalis presl and pontederia cordata was 6.65 kg/m2 and 10.83 kg/m2 respectively,about 6 and ...
