| 英文摘要 | Intercropping of arsenic (As) hyperaccumulator (Pteris vittata L.) with crops can reduce the As concentration in soil and the resulting ecological and health risks, while maintaining certain economic benefits. However, it is still unclear how As-transforming functional bacteria and dominant bacteria in the rhizosphere of P. vittata affect the microbial properties of crop rhizosphere soil, as well as how As concentration and speciation change in crop rhizosphere soil under intercropping. This is of great significance for understanding the biogeochemical cycle of As in soil and crops. This study aimed to use high-throughput sequencing and quantitative polymerase chain reaction (qPCR) to analyze the effects of different rhizosphere isolation patterns on the bacterial diversity and the copy number of As-transforming functional genes in pomegranate (Punica granatum L.) rhizosphere soil. The results showed that the abundance of bacteria in the rhizosphere soil of pomegranate increased by 16.3 %, and the soil bacterial community structure significantly changed. C_Alphaproteobacteria and o_Rhizobiales bacteria significantly accumulated in the rhizosphere of pomegranate. The copy number of As methylation (arsM) gene in pomegranate rhizosphere soil significantly increased by 63.37%. The concentrations of nonspecifically sorbed As (F1), As associated with amorphous Fe (hydr)oxides (F3), and the total As (FT) decreased; the proportion of As (III) in pomegranate rhizosphere soil decreased; and the proportion of As (V) increased in pomegranate rhizosphere soil. c_Alphaproteobacteria and o_Rhizobiales accumulated in crop rhizosphere soil under the intercropping of P. vittata with crops. Also, the copy number of As methylation functional genes in crop rhizosphere soil significantly increased, which could reduce As (III) proportion in crop rhizosphere soil. These changes favored simultaneous agricultural production and soil remediation. The results provided the theoretical basis and practical guidance for the safe utilization of As-contaminated soil in the intercropping of As-hyperaccumulator and cash crops. |
