| 摘 要： | 为了探索吉林省玉米主要种植区土壤微生物的真菌群落多样性特征,采用Illumina MiSeq技术,对吉林省玉米主产区的72个土壤样品进行真菌群落多样性分析,通过土壤理化性质、酶活性特征、多样性指数、冗余分析(RDA)、偏最小二乘法(PL-SDA)等分析玉米种植区土壤微生物群落结构的特征及其与土壤理化性质的关系。结果表明,5种不同类型的土壤pH和有机质差异显著;偏碱性土壤的蔗糖酶、脲酶和碱性磷酸酶的活性较高;风沙土、黑钙土和黑土的真菌丰度显著高于白浆土和暗棕壤,而黑土的真菌多样性最高。所有土壤均以子囊菌门(Ascomycota)为优势菌门,粪壳菌纲(Sordariomycetes)为主要的优势菌纲,酵母菌属(Guehomyces)、青霉菌属(Penicillium)和腐殖霉属(Humicola)是主要的优势菌属。冗余分析结果表明,吉林省玉米种植区土壤pH和有机质是土壤真菌优势类群变化的主要驱动因子。上述的研究结果以期阐明东北黑土区土壤群落与土壤养分之间的关系,为黑土区退化土壤恢复提供理论参考。

| Abstract: | In order to explore the characteristics of fungal community diversity of soil microorganisms in the main maize growing areas in Jilin province,fungal community structure of 72 soil samples in Jilin province was analyzed by Illumina Mi Seq technology method.Soil physical and chemical properties,enzyme activity characteristics and microbiology diversity index,redundancy analysis(RDA)and partial least squares(PL-SDA)were used to analyze the community structure differences and their relationships with soil physical and chemical properties.The results showed that there were significant differences in pH value and organic matter among five soil types;the activities of sucrase,urease and alkaline phosphatase were higher in alkaline soils;the abundance of fungi in sandy soil,chernozem soil and black soil was significantly higher than that in albic bleached soil and dark brown soil,and the diversity of fungi in black soil was the highest.Ascomycota was the dominant fungi phylum in all soils,Sordariomycetes was the dominant fungi class,Guehomyces,Penicillium and Humicola were the dominant fungi genus.Redundancy analysis showed that soil pH and organic matter in maize growing areas in Jilin province were the main driving factors for the change of dominant groups of soil fungi.The above results are expected to clarify the relationship between different types of soil communities and soil nutrients,and provide theoretical support for the restoration of degraded soils in black soil region. |
