“…This indicates that the effects of soil depth and forest type on fungal communities are complex and may be related to different responses of fungi to soil chemical properties under different types of forest stand (Wardle et al, 2004 ). Meanwhile, the lower stand density of the pure forest stand might enhance the diversity of fungal community (Fernandez et al, 2024 ). Moreover, variations in soil chemical properties may affect the relative abundance of species with specific nutritional strategies within the fungal community (such as wood decay fungi and mycorrhizal fungi) (Allison and Martiny, 2008 ).…”

Mixing with different broadleaf trees into the monocultures of Cunninghamia lanceolata is widely adopted as an efficient transformation of the pure C. lanceolata forest. However, it is unclear how native broad-leaved trees influence the belowground ecological environment of the pure C. lanceolata culture plantation in nutrient-poor soil of South China. Herein, we aimed to investigate how a long-time mixing with native broadleaf trees shape soil microbial community of the pure C. lanceolata forest across different soil depth (0–20 cm and 20–40 cm) and to clarify relationships between the modified soil microbial community and those affected soil chemical properties. Using high-throughput sequencing technology, microbial compositions from the mixed C. lanceolata-broadleaf forest and the pure C. lanceolata forest were analyzed. Network analysis was utilized to investigate correlations among microorganisms, and network robustness was assessed by calculating network natural connectivity. Results demonstrated that the content of soil microbial biomass carbon and nitrogen, total phosphorus and pH in mixed forest stand were significantly higher than those in pure forest stand, except for available phosphorus in topsoil (0–20 cm). Simultaneously, the mixed C. lanceolata-broadleaf forest has a more homogeneous bacterial and fungal communities across different soil depth compared with the pure C. lanceolata forest, wherein the mixed forest recruited more diverse bacterial community in subsoil (20–40 cm) and reduced the diversity of fungal community in topsoil. Meanwhile, the mixed forest showed higher bacterial community stability while the pure forest showed higher fungal community stability. Moreover, bacterial communities showed significant correlations with various soil chemical indicators, whereas fungal communities exhibited correlations with only TP and pH. Therefore, the mixed C. lanceolata-broadleaf forest rely on their recruiting bacterial community to enhance and maintain the higher nutrient status of soil while the pure C. lanceolata forest rely on some specific fungi to satisfy their phosphorus requirement for survive strategy.

Research into the effects of plantations, arbuscular mycorrhizal fungi (AMF) inoculation and their interplay on soil microbial communities has emerged as a pivotal focus in the restoration of mining areas. This study investigated how AMF inoculation, plantation density and their interaction shaped bacterial communities in a mining region in Northwest China. A field experiment was conducted with three plantation densities, both with and without AMF inoculation. Soil physicochemical properties, understory vegetation composition, extracellular enzyme activities, as well as soil bacterial and functional communities, were comprehensively analysed. The two‐way ANOVA results revealed significant influences of plantation density and AMF inoculation on the understory vegetation community, soil properties, bacterial communities, and their functional traits (p < .05). Higher planting densities and increased AMF biomass notably elevated soil carbon and nitrogen levels, litter inputs and the clay and silt content of the soil (p < .05). Across all samples, phosphorus limitation was evident in soil microbial activity, as indicated by a vector angle exceeding 45°. Mantel analysis further identified soil carbon and phosphorus as key determinants shaping bacterial communities (Mantel's p < .05). Importantly, AMF inoculation exerted a more pronounced impact on bacterial functional traits compared to plantation density (p < .05). In addition, the intermediate planting density in inoculated treatments yielded the highest available phosphorus, microbial biomass phosphorus and understory vegetation biomass, as well as the lowest microbial phosphorus limitation. Therefore, our study, which provided a comprehensive analysis of the influence of planting density and AMF inoculation on soil and bacterial communities, recommended intermediate planting density and AMF inoculation for optimal results.
