浑河河岸带六种草本植物氮、磷含量特征
Nitrogen and phosphorus contents of six herb species in riparian zone of Hunhe River, Northeast China
摘要
Abstract
In this paper, the root, stem, and leaf samples were collected from six herb species (Artemisia selengensis, Potentilla cryptotaeniae, Impatiens noli-tangere, Artemisia capillaries, Bidens biternata, and Polygonum persicaria) in the riparian zone at the upstream of Hunhe River in July, August, and September, 2010, aimed to compare the total nitrogen (TN) and total phosphorus (TP) contents in the organs of these herb species. In the test organs, the TN and TP contents were 5. 10-45.06 mg · g-1 and 1.60-18.01 mg · g-1 , respectively, and the N/P ratio ranged from 0. 92 to 6. 14, with an average of 2. 68. There existed significant differences in the N and P contents between different organs of the same or different herb species. Among the test five species, I. noli-tangere had the highest TN and TP contents, being able to be selected as a candidate species used for the improvement of water quality in the riparian zone of Hunhe River.关键词
