“…as well as in regulating soil nutrients and ecosystem processes. Owing to the different biological characteristics of various tree species, different effects of species mixture on soil physico-chemical properties are observed [44]. In this study, soil physical properties exhibited significant differences along the soil layer among different forest types.…”

“…Mixed forests significantly reduced the bulk density of soil due to the interspersion of plant roots that make the soil looser and improves soil aeration [47]. Mixed-species plantations significantly improved soil aeration and water holding capacity as well as the soil porosity (i.e., non-capillary and capillary porosity, and total porosity) and water holding capacity, capillary water holding capacity, maximum water holding capacity, and minimum water holding capacity of topsoil and subsoil compared to monoculture Chinese fir plantations [44] -a result similar to our study. Similarly, a decrease in soil bulk density, but an increase in water holding capacity was observed in mixed-species forest during restoration of sodic lands [48].…”

“…In the present study, Acidobacterium, Chloroflexi, Proteobacteria and Actinobacteria dominated the soil bacterial community in pure and mixedspecies plantations. The dominance of Proteobacteria, Acidobacteria, and Actinobacteria have been often associated with the acidic nature of forest soils [44,68]. The relative abundance of Acidobacterium, Chloroflexi and Proteobacteria accounted for about 80% of the phylum composition in pure A. cincinnata stand and for about 78% in mixed-species planting of A. cincinnata and E. robusta as well as A, cincinnata and A. mangium.…”

Establishment of mixed-forests has gained increasing attention as a way to optimize forest production, to improve ecological benefits and as a safety net for impacts of future climate uncertainties. However, practical knowledge about which species and what proportion of them should be mixed is still lacking. Thus, this study was conducted with the aim of identify suitable species for mixture with Acacia cincinnata. The mixture tested in the present study was A. cincinnata + Eucalyptus robusta (6:4), A. cincinnata + Acacia mangium (3:1) and monospecifc plantation of A. cincinnata established in 2014. After 7 years of growth, we analyzed the effects of species mixture on growth of tree species, understory vegetation and soil physico-chemical properties as well as bacterial community structure and diversity. The results showed that species mixture had no significant effect on growth characteristics, such as diameter and singletree volume of A. cincinnata. However, mixed-species planting increased the total stocking volume compered to monospecific plantation of A. cincinnata. Furthermore, stand mixture significantly increased species diversity, biomass and nutrient stocks in the understory vegetation. The soil of mixed stand of A. cincinnata and A. mangium had the highest C and N contents, whereas the soil of pure A. cincinnata stand had the highest P content. The diversity of soil bacterial community were the highest in the mixed stand of A. cincinnata and E- robusta, followed by pure A. cincinnata stand and A. cincinnata + A. mangium stand. The relative abundance of Proteobacteria and Actinobacteria was higher in soils of mixed stands. Furthermore, the relative abundance of Firmicutes was high in the soil of A. cincinnata + A. mangium while the relative abundance of Verrucomicrobia was high in A. cincinnata + E. robusta stand. As a whole, the study demonstrated that establishing mixed-species plantation enhance the diversity and composition of understory vegetation, soil physico-chemical and soils bacterial community; thereby increasing biodiversity, nutrient cycling and carbon sequestration in the biomass and soil. From the viewpoints of forest productivity and ecological benefits, it is advisable to establish a mixed plantation of A. cincinnata and A- mangium in southern China. As a whole, our work revealed that the sustainability of mixed-species plantation relies on the interactions between soil attributes, vegetation, and bacterial community.

“…Traditional Chinese fir cultivation is mainly based on multi-generation continuous planting of pure monoculture. However, long-term continuous cultivation is prone to problems such as soil degradation, productivity decline, soil fertility and microbial diversity decline, which seriously affects the forest ecosystem services and the sustainable management (Guo et al, 2023). The most effective tending measures in the management of Chinese fir plantation are thinning and interplanting to solve these ecological problems.…”

“…The meta-analysis of species mixing effects in Chinese fir plantations revealed a positive effects of species mixing on soil nutrient cycling and ecosystem function, which increased 13.97 and 36.34% of soil physicochemical properties and enzymatic activities (Guo et al, 2023). The interplanting or species mixing are recommend to support the sustainable and healthy development of Chinese fir plantation, however, there is a coupling between density regulation and interplanting tree species selection.…”

ObjectiveRhizosphere soil nutrients and bacterial diversity of four broad-leaved tree species underplanted in Chinese fir plantation with different stand density levels were analyzed to reveal characteristics of the rhizosphere soil environment and selection of suitable underplanted tree species.MethodsChinese fir plantation with three density levels (900, 1,200, and 1,875 stems ha–1, respectively) were selected and underplanted with Michelia macclurei, Schima superba, Phoebe zhennan, and Tsoongiodendron odorum. The rhizosphere soil nutrients and bacterial community of the broad-leaved tree species were determined after 4 years.ResultsSignificant differences in rhizosphere nutrient content were detected among different tree density levels, where the contents of total K, available K and available P in 900 stems ha–1 stands were significantly higher than the other stocking density levels. There were also significant differences in the contents of total C, total N, total K, available K and available P in the rhizosphere soils of the four trees species, while there were no significant differences in pH and total P. Rhizosphere soil nutrient contents were higher under S. superba and M. macclurei than under P. zhennan and T. odorum. The rhizosphere soil nutrient contents and bacterial diversity decreased with the increase of stand density, and the bacterial diversity showed significant differences in the rhizosphere soils of P. zhennan, T. odorum and S. superba when underplanted in different stand densities. The bacterial diversity was positively correlated with the available P content of rhizosphere soils, suggesting that soil available P content plays an important role in shaping the structure of bacterial community.ConclusionThe nutrient contents and bacterial diversity of rhizosphere soils of underplated broad-leaved species decreased with increasing stand density of Chinese fir plantation. Rhizosphere soils of M. macclurei and S. superba were rich in nutrient contents and bacterial diversity. Thus, low density of Chinese fir plantation (900 stems ha–1) underplanted with M. macclurei and S. superba is suitable for the establishment of mixed forest, which will facilitate better tree growth and maintaining soil fertility to realize sustainable management of forests.
