| 英文摘要 | Rhizosphere effects of microbial necromass carbon vary with arbuscular mycorrhizal and ectomycorrhizal tree types, determining soil organic carbon (SOC) sequestration. The aim of this study was to determine how the rhizosphere effects were regulated by initial soil nutrients, microbial properties (resource limitation), and root traits. We investigated the rhizosphere effects of 14 tree species (7 arbuscular mycorrhizal and 7 ectomycorrhizal tree species), on bacterial necromass carbon (BNC) and fungal necromass carbon (FNC) contributions to the SOC pool, and their underlying factors, in a subtropical plantation. The results showed that both arbuscular mycorrhizal and ectomycorrhizal tree species exhibited positive rhizosphere effects on BNC, FNC, and SOC (p < 0.05). Ectomycorrhizal trees demonstrated a significantly greater rhizosphere effect on FNC compared to arbuscular mycorrhizal tree species (463 % vs. 239 %, p < 0.05), while differences in BNC and SOC were not significant. The rhizosphere effect on SOC was primarily driven by the changes in FNC for both tree types. However, the dominant regulatory impacts of their driving factors varied largely with mycorrhizal type. Specifically, microbial resource limitations were the main determinant for arbuscular mycorrhizal tree species, while root traits played a more important role than other factors in ectomycorrhizal tree species. These findings underscore the critical role of mycorrhizal-associated rhizosphere processes in SOC formation, particularly through fungal pathways, and provide mechanistic insight into how root-microbial interactions shape carbon cycling in forest soils. |
