不同植物组织对氮磷元素富集效应研究

Studying the absorption of nitrogen and phosphorus by aquatic plants in Luoma lake,this paper discovered that in seven kinds of large aquatic plants of rushes, reed, arrowhead,eelgrass,goldgrass,malaianus and myriophyllum, nitrogen and phosphorus are better absorbed by eelgrass. Compared with malaianus Community, Myriophyllum community has a greater impact on nutrients. However,analysis of variance showed that there is no significant difference in changes of nutrient under the action of the two communities. Different organizations within a plant had differences on nitrogen and phosphorus enrichment, which related to the way of growth and nutrient cycling in the plants. According to the analysis of nutrient content in the same tissue of different plants,it showed that nutrient enrichment in the same tissue of different plants had more obvious differences.
