In this study,under laboratory conditions,using traditional microbiological culture method,select the Pb2+ stress training of Pistia stratiote and Myriophyllum spicatum L. under water culture, through the changs of root- microbial of Pistia stratiote and Myriophyllum spicatum L.,the results show that bacteria,fungi,actinomycetes have different concentrations under Pb2+ stress. It is specificity of ammonification, nitrification,andanti-Nitrosation after Pb2+ stress.

中文摘要：本研究在实验室条件下，用传统的微生物培养法，选择重金属离子Pb2+在水培条件下对大薸和穗状狐尾藻进行胁迫培养，通过测定大薸和穗状狐尾藻根系的微生物区系及与氮循环有关的四种细菌的数量变化发现：细菌、真菌、放线菌对重金属Pb2+的不同浓度的敏感性不同；重金属Pb2+胁迫对氨化、硝化、亚硝化和反硝化四类细菌的影响也表现出各自的特殊性。

In laboratory conditions, using the traditional microbiological culture, a different concentration on the source of heavy metals Cd6+ stress the Pistia stratiotes root of the microbial flora and major groups of physiological effects.
