不同植物组织对氮磷元素富集效应研究
首发时间:2010-08-31
摘要:研究了骆马湖水生植物对N、P的吸收效果,结果表明在蒲草、芦苇、慈菇、苦草、金丝草、马来眼子菜、狐尾藻7种大型水生植物中苦草对N、P均有较好的吸收;马来眼子菜群落和狐尾藻群落相比,狐尾藻群落对营养盐的影响更大,但是方差分析表明,两种群落作用下,营养盐的变化并无显著性差异;同一种植物的不同组织对氮磷的富集具有差异性,这与植物的生长方式与营养盐在植物体中的循环有关;根据不同植物的相同组织营养盐含量分析,不同植物的相同组织对营养盐的富集均具有较明显的差异性。

Different Plant Tissues on The Effects of Nitrogen and Phosphorus Enrichment
Abstract: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.
