Phytoremediation is a method of clearing up pollutants from environment by *** has the advantages of low cost,saving land resources and no secondary *** importantly,it does not destroy the ecological *** it has a bright future for apply phytoremediation in cleaning the contaminated *** is a herbicide that is widely used in ***(Populus deltoids cv.I-69/55)and transgenic poplar(Populus deltoides × nigra,DN34)in pots were used to test if they remediate atrazine contaminated soil in a greenhouse in this *** degradation dynamic of atrazine was studied in different rhizosphere environment with GC method;the dynamic variation of microbe was investigated to elucidate the rhizosphere effects and mechanism of phytoremediation of Atrazine contaminated soil by transgenic poplar,in the process of *** main results were summarized as follows:1)There was no significant difference in atrazine(the applied concentration was 10 mg·kg-1 in the soil of pots)between the ordinary poplar rhizosphere soil and the non-rhizosphere *** transgenic poplar was able to clean up *** was significant difference in atrazine between the transgenic poplar rhizosphere soil and the non-rhizosphere soil.2)The bacteria in non-rhizosphere soil were significantly inhibited by 10 mg·kg-1 *** number of bacteria,fungi and actinomycosis in rhizosphere soil was more than that in non-rhizosphere *** number of bacteria in transgenic poplar rhizosphere soil remained stable,and was generally more than that in other rhizosphere *** number of actinomycosis was in an order:non-contaminated soil >rhizosphere soil contaminated with atrazine>non-rhizosphere soil contaminated with atrazine.
