Removal efficiency of nitrogen, phosphorus and N2O emission from domestic sewage in floating-bed system with Lolium mutliflorum, Oenanthe javanica and Vetiveria Zizanioides were investigated in greenhouse.

在温室内采用浮床无土栽培技术，研究了黑麦草、水芹和香根草3种植物对生活污水中N、P的去除效果及净化过程中N2O的排放特征。

With retention time prolonged, the concentrations of TN, NH4(superscript +)-N and TP of domestic sewage were obviously reduced in all floating-bed systems, however the NO4(superscript +)-N concentrations were gradualjy accumulated due to the stronger nitrification than denitrification. The plants in floating-bed system increased significantly the N2O flux, which was 174.44μg/(m^2h), 82.19μg/(m^2h), 112. 49μg/(m^2h) and 44.81μg/(m^2h), respectively, for the Lolium mutliflorum, Oenanthe javanica, Vetiveria Zizanioides arid none-plant floating-bed systems.

净化周期内，浮床各系统的TN、NH4-N和TP浓度随着污水停留时间的延长直线下降，而NO3-N浓度却因系统内硝化强度大于反硝化强度而产生了累积；植物的存在明显的促进了浮床系统的N2O排放，浮床黑麦草、水芹、香根草和对照系统N2O的平均排放通量分别为174.44μg/， 82.19μg/， 112.49μg/和44.81μg。

Vetiveria zizanioides grow in ringent hinge jointed concrete extending system, and its roots are interlaced and make foundation soil into compound materials of soil and roots, but grass roots are considered as three-dimensional reinforced materials which increase soil strength and the stability of bank protection.

通过在开孔的铰链式混凝土块铺面系统中种植香根草，其根系在基土中盘根错节，使基础土体成为土与草根的复合材料，草根可视为三维加筋材料，使土体强度提高；更有利于护岸防冲系统的稳定。

Vetiveria zizanioide is possesses strong depth roots and have better anchoring force and shear resistance; Vetiveria zizanioides is growed in ringent hinged joined concrete extending system,and its roots are interlaced and make foundation soil compound materals of soil and roots,but grass roots are considered three-dimensional reinforced materal and increase soil strength but also make for the stability of bank protection.

香根草具有纵深发达的根系系统，具有较高的锚固力和抗剪力。通过在开孔的铰链式混凝土块铺面系统中种植香根草，其根系在基土中盘根错节，使基础土体成为土与草根的复合材料，草根可视为三维加筋材料，使土体强度提高；更有利于护岸防冲系统的稳定。关键词：香根草，铰链式混凝土块，防冲护岸系统

The aim of the study was to discuss the physiological change law in Vetiveria zizanioides under waterlogging stress.

Drought tolerance capacity of Vetiveria zizanioides is much better under high temperature in summer.It can tolerate drought from 24 to 42 days.

香根草Vetiveria zizanioides是禾本科C4植物，原产于热带，具有良好的水土保持功能，过去几十年里在全球的热带和亚热带地区迅速推广应用。

Vetiveria has traditionally been separated from Chrysopogon on the basis of its longer racemes composed of a number of spikelet pairs in addition to the terminal triad.

Vetiveria 传统上根据除顶生的三人小团伙之外还由许多小穗对组成的它的长总状花序与Chrysopogon分离。

Soil and water conservation effects from using Vetiveria zizaniodes to protect the slope were significant. Soil loss from the slope where Vetiveria zizaniodes grows decreased by 92.24%, and the slope was stable compared with the control plots.

采用香根草生态护坡技术治理弃土场边坡水土流失，水土保持效果显著，坡面土壤流失量比对照小区减少92.24%，边坡稳定。
