- Abstract
While afforestation helps mitigate climate concerns, the impact of plantation type and afforestation age on soil microbial compositions in afforested areas remains unclear. The current study utilized high‐throughput deep sequencing to investigate the effect of afforestation ages (3 months, 1 year and 6 months, and 15 years) and two different tree species (Pinus tabulaeformis Carr. and Sophora japonica L.) on soil microbiomes and edaphic conditions in afforested plots in the Xiong'an New Area, where soil experienced considerable disturbance by human activities during land preparation. Partial least squares path modelling showed that the afforestation age negatively influenced edaphic conditions. The results of fungal and bacterial biomass showed that bacterial lineages were replaced by fungal lineages as the afforestation age increased. Values of different soil particle sizes were impacted by increased stand ages. PERMANOVA results indicated that the plantation type could significantly explain 35.91% (p = 0.0065) and 23.84% (p = 0.009) of the bacterial and fungal β‐diversity variations, respectively. In contrast, the afforestation age could explain 35.46% (p = 0.017) of the fungal β‐diversity variation significantly. Additionally, our data showed that the co‐occurrence network for P. tabulaeformis plots was more complex than that for S. japonica plots, and network complexity increased with the afforestation age. The above results indicated that plantation type and afforestation age disclose variable influence on soil microbial compositions in man‐made forests in the Xiong'an New Area, China, which provide a basis for subsequent broader framework afforestation programs.
