摘　　要：为深入了解牡丹不同种植模式(林下种植、裸地种植)对土壤真菌群落的组成和多样性及土壤养分状况的影响,采用Illumina NovaSeq高通量测序技术,对比分析2种种植模式下土壤真菌群落的结构和多样性及土壤养分。结果表明,土壤环境和真菌群落的组成对凤丹牡丹的生长和繁殖有显著影响,裸地种植土壤样品中担子菌门占比最高,而林下种植土壤样品中子囊菌门和被孢霉门的丰度更高,林下种植牡丹根际土壤中真菌物种丰度显著高于裸地种植土壤样品;土壤有机质、有效磷、速效钾含量对真菌种群组成有显著正向影响,不同的真菌群落与这些土壤矿质元素含量有显著相关性,林下种植土壤中的优势菌群多呈现正相关性。综合结果表明,林下种植可以有效提升土壤真菌群落丰度和多样性,林下种植的牡丹对环境的适应性更强。In order to further understand the composition and diversity of soil fungal communities under different planting patterns of Paeonia suffruticosa,and to evaluate the effects of two planting patterns on soil nutrient status,Illumina NovaSeq high-throughput sequencing technology was used to compare and analyze the structure and diversity of soil fungal communities under two different planting patterns.To explore the effects of two planting methods on soil nutrients.The results showed that soil environment and the composition of fungi community had significant effects on the growth and reproduction of Paeonia suffruticosa.Basidiomycetes accounted for the highest proportion in bare soil samples,while ascomycetes and mortieromycetes were more abundant in understory samples.The abundance of fungi species in rhizosphere of Paeonia suffruticosa in understory samples was significantly higher than that in bare soil samples.Soil organic matter,available phosphorus and available potassium contents had significant positive effects on fungal population composition.There was significant correlation between different fungal communities and the content of mineral elements in these soils,and most of the dominant bacterial species in understory soil showed positive correlation.It was speculated that the decomposition of branches and leaves litter on the soil surface increases the soil nutrient content,and the secondary metabolites of plant roots provide a superior growth environment for microorganisms.The results showed that understory planting could effectively improve the abundance and diversity of fungal communities.Paeonia suffruticosa planted under the forest are more adaptable to the environment.
