摘要:
以灰枣和骏枣根际土壤为试材，采用Illumina Miseq测序技术分析了不同地区不同品种红枣黑斑病病株及健株根际土壤真菌群落组成和多样性；对土壤理化性质与根际土壤真菌丰富度前20位优势菌属之间的相关性进行分析。通过探究南疆地区发生红枣黑斑病根际土壤真菌群落的多样性，以期揭示新疆红枣发病与其根际土壤真菌群落之间的相关性，为生物防治提供思路和方法。结果表明：阿克苏和喀什地区灰枣和骏枣的根际土壤真菌测序中共获得6 221 336个有效标签，17 239个OTUs共鉴定出21个门42个纲299个属，其中80%为子囊菌门和担子菌门。阿克苏地区灰枣根际土样和骏枣根际土样中的菌属分别聚类在一起，喀什地区灰枣根际土样和骏枣根际土样中的菌属分别聚类在一起。RDA分析表明，发病灰枣土样中有效磷和pH对土壤微生物群落结构的影响最大，发病骏枣土样中有机碳、速效钾和pH对土壤微生物群落结构的影响最大。红枣黑斑病根际土样中真菌群落组成丰富，同一地区不同红枣品种根际土真菌群落结构存在显著差异；发病红枣根际土壤真菌群落多样性与土壤环境因子之间存在一定相关性。
Abstract:
Rhizosphere soil of gray jujube and Junzao were taken as materials.The Illumina Miseq high-throughput sequencing technology was used to analyze the composition，abundance and diversity of rhizosphere soil fungi community in different varieties of jujube black spot disease and healthy plants in different regions.The correlation between soil physical and chemical properties and the top 20 dominant species in the rhizosphere soil fungi richness was analyzed.In order to explore the diversity of fungal community in rhizosphere soil of black spot disease in southern Xinjiang，the intrinsic relationship between Xinjiang jujube disease and soil fungal community was revealed from the perspective of fungal community of rhizosphere soil in diseased jujube，to provide ideas for biological control.The results showed that 6 121 336 effective tags were obtained from the fungal sequencing of rhizosphere soil samples of gray jujube and Junzao in Aksu and Kashi regions，and 17 239 OTUs identified a total of 21 phyla and 299 genera in 42 phyla，80% of which were ascus Mycophyta and Basidiomycota.The fungi in the gray jujube rhizosphere soil samples and Junzao rhizosphere soil samples in the Aksu area were clustered separately，and the gray jujube rhizosphere soil samples in the Kashi area and Junzao rhizosphere soil samples were clustered together.RDA analysis showed that available phosphorus and pH in the soil samples of the diseased gray jujube had the greatest effect on the soil microbial community structure，and organic carbon，available potassium and pH in the soil samples of the diseased Junzao had the greatest effect on the soil microbial community structure.The fungal community composition was rich in the rhizosphere soil samples of the jujube black spot.The rhizosphere soil fungi community structure of different varieties in the same area was significantly different.There was a certain correlation between the diversity of the rhizosphere soil fungal community and the soil environmental factors in the same region.
