摘      要：Dendroremediation,a novel strategy for cleaning up contaminants from the environment by using special woody plant species and microbes,is a popular phytoremediation *** is a cost-effective and environmentally friendly method that is being increasingly *** species(Populus L.)have been suggested for use in remediation because of their characteristics of high biomass production,fast growth,and potential for removing *** environment is often contaminated by toxic substances produced by human activities,and remediation of contamination is therefore a global *** is one of the most widely used herbicides in *** the present study,‘I-69/55’poplar(*** cv.‘I-69/55’)and hybrid poplar(Populus deltoides×nigra,DN34)grown in pots were assayed for their ability to remediate atrazine-contaminated *** degradation dynamics of atrazine were assessed with a high-performance liquid chromatography system using materials from a greenhouse with different rhizosphere *** studied the dynamic variation in microbes and microbial biomass carbon to elucidate the rhizosphere effects and mechanism of remediation of atrazine-contaminated soil by *** four treatments included a control with uncontaminated soil without a tree,atrazine pollution without a tree,atrazine pollution with‘I-69/55’poplar,and atrazine pollution with hybrid *** poplar showed potential for remediation of atrazine-contaminated soil,and the degradation of atrazine in the rhizosphere was faster than that in non-rhizosphere *** significantly inhibited bacteria growth in nonrhizosphere *** high concentration of bacteria in the hybrid poplar rhizosphere might be key to atrazine *** of change among fungi and actinomyces did not correspond to trends in atrazine degradation throughout the trial *** research is needed to predict the effects of atrazine on cultivable microorganisms in various *** had s
