| 英文摘要 | The effects of phosphate rock (PR), bone charcoal (BC), single superphosphate (SSP) and calcium magnesium phosphate (CMP) on rice growth and bacterial community structure in mining area of heavy and light rare earth elements(REEs) were studied by pot experiment, field experiments were conducted with CMP and BC as restorative materials. The pot experiment showed that BC, SSP and CMP improved dry weight of rice (especially grains) in two places by 84.23%, 116.97%, 81.83%, 1630.77%, 1817.95% and 902.56% respectively; and reduced REE content of rice (especially roots) in two places by 28.19%, 81.67%, 90.58%, 67.87%, 81.72% and 94.81%; PR had little effect on dry weight and REE content of rice in both places, but reduces Bacillusabundance in both places, while BC significantly improved the abundance of Perlucidthaca and Bacillus; CMP had little effect on bacterial community, two-year field experiments showed that dry weight of rice grain treated with BC was 100% and 43.0% higher than that treated with CK and CMP, and the content of REEs was 91.8% and 16.8% lower than that with CK and CMP. The results of pot and field experiments both show BC is the most potential material for restoring soil-plant ecosystem in REE mining area. |
