Summary
This study investigates how stand age in long-term Lycium barbarum (wolfberry) monoculture affects soil microbial community structure, diversity, and network dynamics in the root zone. Using high-throughput sequencing and network analysis, the authors found that plant age significantly modulates bacterial and fungal diversity, with Proteobacteria and Ascomycetes remaining dominant across all ages. The research suggests that stand age indirectly regulates microbial diversity and network complexity primarily through changes in soil physicochemical properties, offering insights for managing soil quality in perennial monoculture systems.
UK applicability
Whilst wolfberry is not widely cultivated commercially in the UK, the methodological approach and findings on how long-term monoculture affects soil microbial assembly and network stability may be applicable to UK perennial horticulture systems (e.g. apple orchards, soft fruit). The emphasis on soil health degradation under monoculture aligns with UK regenerative agriculture policy priorities.
Key measures
Bacterial and fungal α-diversity (Shannon and Chao1 indices), community composition at phylum and genus level, stochastic vs. deterministic assembly processes, network complexity and stability metrics, soil physicochemical properties, partial least squares path modelling analysis
Outcomes reported
The study characterised bacterial and fungal community diversity, composition, assembly mechanisms, and symbiotic network complexity across wolfberry plants of different stand ages, using high-throughput sequencing and network analysis. Stand age was shown to significantly influence microbial α-diversity, community structure, assembly processes, and network stability in the root zone soil.
