摘要:
采用Illumina MiSeq高通量测序技术探究茶园阴坡和阳坡土壤细菌、真菌群落结构特点，并开展土壤理化因子对土壤细菌、真菌群落结构的影响分析。结果表明，茶园阴坡土壤细菌和真菌分类操作单元数量均高于阳坡。在门分类水平上，阴坡土壤中相对丰度最高的细菌门为酸杆菌门，阳坡为变形菌门，而阴坡和阳坡土壤中相对丰度最高的真菌门均为子囊菌门，相对丰度均超过55.00%；在目分类水平上，茶园阴坡和阳坡土壤相对丰度最高的细菌、真菌均不同。物种多样性分析结果显示，阴坡和阳坡茶园土壤间细菌和真菌物种多样性和物种相对丰度均无显著差异。阴坡和阳坡富集的细菌不同，而富集的真菌较为相似。冗余分析结果显示，细菌受土壤因子的影响大于真菌，且土壤速效磷含量是影响土壤细菌和真菌群落最主要的环境因子。
Abstract:
Illumina MiSeq high-throughput sequencing technology was used to explore the bacterial and fungal community structure characteristics of the shady slope and sunny slope of tea garden, and analysis of the effects of soil physical and chemical factors on the bacterial and fungal community structures was conducted. The results showed that the number of bacterial and fungal operational taxonomic units (OTUs) in the shady slope soil was higher than that in the sunny slope soil. At the phylum classification level, the bacterial phyla in the shady slope soil and the sunny slope soil with the highest relative abundance were Acidobacteria and Proteobacteria respectively, and the most abundant fungal phylum in both slopes was Ascomycota, with a relative abundance exceeding 55.00%. At the order classification level, the most abundant bacteria and fungi in the shady slope soil and sunny slope soil were different. Species diversity analysis showed that there was no significant difference in species diversity or richness of bacterial and fungal communities in the soils between the shady and sunny slopes of the tea garden. Different bacterial species were enriched in the shady slope and sunny slope soils, while the fungal species enriched were similar. Redundancy analysis found that bacteria received greater influence by soil factors than fungi, and soil available phosphorus content was the most important environmental factor affecting soil bacterial and fungal communities.
