摘　　要：以南疆不同树龄核桃园土壤为试材,采用Illumina Mieq高通量测序方法,研究了不同树龄土壤真菌多样性,以期为生物菌肥及生防菌剂的开发与应用提供参考依据。结果表明:不同树龄核桃园土壤真菌群落结构存在明显差异,但不同树龄土壤真菌优势类群均为子囊菌门(Ascomycota)、担子菌门(Basidiomycota)以及接合菌门(Zygomycota)。且随着年份的增长土壤真菌丰富度先增加后降低,而多样性随年份增加逐年升高。在门、纲、目、科和属分类水平上,丰度一直增加的土壤真菌类群分别为子囊菌门(Ascomycota)、酵母菌纲(Saccharomycetes)、散囊菌纲(Eurotiomycetes)、酵母菌目(Saccharomycetales)、小鬼伞科(Psathyrellaceae)、柯达酵母属(Kodamaea)、假鬼伞属(Coprinellus)。该研究揭示了南疆不同树龄核桃园土壤真菌群落的多样性,探明了不同树龄核桃园土壤真菌群落结构的变化规律,为开发利用土壤真菌资源和深入研究土壤真菌多样性与果树营养水平之间的联系打下基础。Taking the soil of different walnut orchards in southern Xinjiang as the test material,Ilumina Mieq high-throughput sequencing method was used to study the fungal diversity in soil of different ages,in order to provide reference for the development and application of bio-fertilizers and biocontrol agents.The results showed that there were significant differences in soil fungal community structure among different tree ages,but the dominant groups of soil fungi in different tree ages were Ascomycota,Basidiomycota and Zygomycota.With the increase of years,the richness of soil fungi first increased and then decreased,while the diversity increased with the increase of years.At the level of phyla,class,order,family,and genus classification,the soil fungi that had been increasing in abundance were Ascomycota,Saccharomycetes,Eurotiomycetes,Saccharomycetales,and Psathyrellaceae,Kodamaea,Coprinellus.The diversity of soil fungal community in walnut orchard of different ages and the changes of soil fungal community structure in walnut orchard of different ages were clarified,which laid a foundation for the development and utilization of soil fungal resources and further research on the relationship between soil fungal diversity and fruit tree nutrition level.
