英文摘要 | Liming, as a common amelioration practice worldwide, has the potential to alleviate soil acidification and ensure crop production. However, the impacts of long-term liming on the temperature sensitivity (Q(10)) of soil organic carbon (SOC) mineralization and its response to labile C input remain unclear. To fill the knowledge gap, soil samples were collected from a long-term (similar to 10 years) field trial with unlimed and limed (CaO) plots. These soil samples were incubated at 15 degrees C and 25 degrees C for 42 days, amended without and with C-13-labeled glucose. Results showed that compared to the unlimed soil (3.6-8.6 mg C g(-1) SOC), liming increased SOC mineralization (6.1-11.2 mg C g(-1) SOC). However, liming significantly mitigated the positive response of SOC mineralization to warming, resulting in a lower Q(10). Long-term liming increased bacterial richness and Shannon diversity as well as their response to warming which were associated with the decreased Q(10). Furthermore, the decreased Q(10) due to liming was attributed to the decreased response of bacterial oligotrophs/copiotrophs ratio, beta-glucosidase and xylosidase activities to warming. Labile C addition had a strong impact on Q(10) in the unlimed soil, but only a marginal influence in the limed soil. Overall, our research highlights that acidification amelioration by long-term liming has the potential to alleviate the positive response of SOC mineralization to warming and labile C input, thereby facilitating SOC stability in agroecosystems, especially for acidic soils in subtropical regions. |
