Exploring the variations of soil bacterial communities can contribute to the sustainability of Chinese fir plantations (CFPs). As the living environments of soil bacteria, soil aggregates significantly affect the diversity and composition regarding soil bacterial communities in CFPs. However, the distribution characteristics exhibited by soil bacteria at the aggregate scale are still not clear. In the present research, the diversity and composition regarding soil bacterial communities (using high-flux sequencing) in CFPs with diverse stand ages (3, 9, 17, and 26 years) were analyzed from the perspective of soil aggregates (>2, 1-2, 0.25-1, <0.25 mm) in Guangxi, China. According to the results, regardless of the aggregate size and the stand age, bacterial communities in soil were mainly composed of Proteobacteria, Chloroflexi, and Acidobacteria. During Chinese fir growth, the relative abundance (RA) of soil Proteobacteria first elevated and afterwards reduced, with the greatest level in the 17 years, while that of soil Chloroflexi exhibited an inverse trend. In addition, the RA of soil Acidobacteria increased over time. At the aggregate scale, the 17-year-old CFPs presented the greatest soil bacterial community diversity (based on the Chao 1 and Shannon indices). After 17 years, the destruction of coarse macroaggregates (>2 mm) could induce the reduction of soil bacterial community diversity, as coarse macroaggregates, taking up the majority of bulk soil, offered suitable environments for soil bacteria to survive and thrive. Moreover, soil organic C and total N concentrations and soil pH also significantly affected the diversity and composition regarding soil bacterial communities over time. Hence, the conservation of coarse macroaggregates after 17 years of Chinese fir growth is important to sustain the soil health as well as the bacterial community diversity in Guangxi, China.

“…Under the long-term influence, AMF will evolve into different community compositions (Mirzaei and Moradi, 2017). Some studies have compared natural forests and Chinese fir plantations and concluded that the decrease in soil physical and chemical properties of Chinese fir plantations had caused the diversity changes in the fungal community (Guo et al, 2022). This study shows a significant correlation between AP content and AMF species diversity and its dominant genera.…”

The diversity of the rhizosphere arbuscular mycorrhizal fungi (AMF) community is a crucial factor affecting root-soil interaction. They can absorb carbohydrates from the host body and return the nutrient elements from the soil to the host. Using 15 Chinese fir (Cunninghamia lanceolata Lamb. Hook.) clones, the AMF richness, abundance and community structure in “Root system-Rhizosphere soil-Bulk soil” were obtained by Real-time quantitative PCR (qPCR) and Illumina Miseq sequencing techniques. The results showed that under the same Chinese fir clone, the total amount of AMF was in the order of rhizosphere soil > root system > bulk soil. The species diversity and uniqueness of AMF were in the order of root system > rhizosphere soil > bulk soil. There was a significant correlation between soil-available phosphorus and AMF diversity and its dominant genera and species. Regarding AMF abundance, Chinese fir clone S18 is the highest, followed by clones Y061 and P17. There was a significant difference in AMF richness among different clones, and Glomus was the dominant genus of AMF. The AMF species diversity of P17 and S2 in roots and rhizosphere soil was high, indicating a good symbiosis between roots and the AMF community. However, the AMF diversity of clones P11 and P41 was low, and the variation of AMF community composition in the group was small. The root-soil interaction caused the AMF community to gather in the rhizosphere but had less symbiosis present with roots. Still, the AMF diversity of the rhizosphere soil of both clones was high. There was a significant correlation between the soil-available phosphorus content and the species diversity of AMF and its dominant genera and species. In conclusion, Clone P17 has high AMF richness and abundance and forms a good symbiosis with AMF, which could be a nutrient-efficient clone of Chinese fir.

“…This phenomenon was also observed during the transformation of other pure plantations, such as E. grandis (Pereira et al, 2021) and Robinia pseudoacacia (Dong et al, 2021), and may be attributed to the marked differences in soil chemical properties and enzyme activities caused by different management patterns (Xu et al, 2020). Yang et al (2019) and Guo et al (2022) reported that soil fungal diversity and abundance were highly positively correlated with soil pH and organic C and N contents. Similarly, soil pH, OM, NO¯ 3_N, and AZn contents Frontiers in Microbiology 07 frontiersin.org maintained a highly positive relationship with fungal diversity, richness, and evenness in this study.…”

“…Meanwhile, Sordariomycetes, Dothideomycetes, and Eurotiomycetes were significantly enriched in mixed plantations in the form of saprophytic or pathogenic fungi. Soil enzyme activity, as one of the functional manifestations of soil, is notably influenced by plantation management patterns (Guo et al, 2022). Although soil extracellular enzymes are secreted by both bacteria and fungi, their activity is mainly driven by fungi (Jin et al, 2019).…”

The continuous planting pattern of eucalypt plantations negatively affects soil quality. A mixed planting pattern using native species implanted in pure plantations has been considered a preferable measure for this problem. However, the impact of this approachon the structure and function of fungal communities is not clear. Here, harvesting sites that had undergone two generations of eucalypt plantations were selected to investigate soil fungal community structure and the co-occurrence network characteristics in response to two silvicultural patterns involving the third generation of eucalypt plantations (E) and mixed plantations of Eucalyptus. urograndis × Cinnamomum. camphora (EC) and E. urograndis × Castanopsis. hystrix (EH). Compared with the first generation of eucalypt plantations (CK), E markedly weakened enzyme activities associated with carbon-, nitrogen-. and phosphorus-cycling. Reduced soil fungal alpha diversity, and elevated the relative abundance of Basidiomycota while decreasing the abundance of Ascomycota. In contrast, EC and EH not only enhanced fungal alpha diversity, but also reshaped fungal composition. At the class level, E caused an enrichment of oligotrophic Agaricomycetes fungi, classified into symbiotroph guild, while EC markedly decreased the abundance of those fungi and increased the abundances of Sordariomycetes, Dothideomycetes, Eurotiomycetes, and Tremellomycetes fungi, which were classified into saprotroph or pathotroph guild. Moreover, fungal network complexity and robustness topological attributes were higher or significantly higher in mixed plantations soils compared with those of pure eucalypt plantation E. Furthermore, fungal diversity, structure, and functional taxa were significantly affected by soil organic matter, pH, total nitrogen, and nitrate nitrogen.
