| 英文摘要 | In this study, we investigated the effects of lanthanum (La), one of the rare earth elements (REEs), on microbial biomass C as well as the decomposition of C-14-labelled glucose in a fluvo-aquic soil in 28 days. The soil was collected from the field plots under maize/wheat rotation in Fengqiu Ecological Experimental Station of Chinese Academy of Sciences, Henan Province, China. Application of La decreased soil microbial biomass C during the experimental period, and there was a negative correlation (P< 0.01) between microbial biomass and application rate of La. La increased microbial biomass C-14 after C-14 glucose addition, and the increase was significant (P< 0.05) at the rates of more than 160 mg kg(-1) soil. La slightly increased (CO2)-C-14 evolution at lower rates of application but decreased it at higher rates 1 day after C-14 glucose addition, while there was no significant effect from days 2 to 28. For the cumulative (CO2)-C-14 evolution during the incubation of 28 days, La slightly increased it at the rates of less than 120 mg kg(-1) soil, while significantly decreased (P< 0.05) it at the rate of 200 mg kg(-1) soil. The results indicated that agricultural use of REEs such as La in soil could decrease the amount of soil microbial biomass and change the pattern of microbial utilization on glucose C source in a short period. |
