摘　　要：【目的】研究不同种植模式下,新疆1年春季种植(SPS1)、2年春季连作种植(SPS2)以及一年夏季种植(SUS)板蓝根对板蓝根根内真菌群落结构的影响。【方法】利用高通量测序技术对板蓝根根系内生真菌进行鉴定与分析根系内生真菌群落结构。【结果】根内真菌在门水平上主要由子囊菌门Ascomycota,被孢霉门Mortierellomycota,担子菌门Basidiomycota,壶菌门Chytridiomycota,油壶菌门Olpidiomycota,芽枝霉门Blastocladiomycota,球囊菌门Glomeromycota,罗兹菌门Rozellomycota和毛霉门Mucoromycota组成。与SUS相比,SPS1显著降低了杓兰菌根菌Neonectria以及青霉菌Penicillium的相对丰度,但是却提高了头珠霉属Oedocephalum的相对丰度,SPS2显著增加了土壤Ascomycota和Chytridiomycota的丰度,显著降低了Mortierellomycota的丰度;但提高了镰刀菌Fusarium,黄曲霉Aspergillus,枝顶孢霉属Acremonium,赤霉属Gibberella以及新月双镰孢Bisifusarium物种的相对丰度。与SPS1相比,SPS2显著降低了Mortierella和Plectosphaerella的相对丰度,但提高了镰刀菌Fusarium,枝顶孢霉属Acremonium和杓兰菌根菌Neonectria的相对丰度。【结论】不同种植模式下板蓝根内生真菌的种群结构存在差异,连续种植会降低有益真菌丰度和增加病原真菌的相对丰度,增加连作障碍的风险。【Objective】Endophytic fungi have a significant impact on the physiology,development and health of the host,can stimulate the germination and growth of the host plant,and play an important role in regulating the nutrient absorption and enhancing the stress resistance of the host plant.This study aims to reveal the effects of different planting patterns of one-year spring planting(SPS1),two-year spring continuous planting(SPS2)and one-year summer planting(SUS)on the fungal community structure of Isatidis root in Xinjiang.【Methods】High throughput sequencing technology was used to identify and analyze endophytic fungi community structure of Radix isatidis root.【Results】At the phylum level,endorhizoidal fungi were mainly composed of Ascomycota,Mortierellomycota,Basidiomycota,Chytridiomycota,Olpidiomycota,Blastocladiomycota,Glomeromycota,Rozellomycota and Mucoromycota.Compared with SUS,SPS1 decreased the relative abundance of Neonectria and Penicillium significantly,but increased the relative abundance of Oedocephalum.SPS2 increased the abundences of Ascomycota and Chytridiomycota significantly,but significantly decreased the abundences of Mortierellomycota.However,it increased the relative abundance of Fusarium,Aspergillus,Acremonium,Gibberella and Bisifusarium.Compared with SPS1,SPS2 decreased the relative abundations of Mortierella and Plectosphaerella significantly,but increased the relative abundances of Fusarium,Acremonium and Neonectria.【Conclusion】The population structure of endophytic fungi in isatidis root is different under different planting patterns.Continuous planting would decrease the abundance of beneficial fungi and increase the relative abundance of pathogenic fungi and increase the risk of continuous cropping obstacles.
