摘要: 采用454高通量测序(454 high throughput sequencing)分析方法,研究不同覆被(光板地和柽柳群落以及白茅群落)类型下土壤真菌组成、多样性及与理化性质的关系。该研究共获得5门174属真菌,不同土样中真菌种类和多样性有所不同,其中,白茅群落真菌的种类较多,尤其是HZ3A(白茅0~20 cm)中真菌属数量最多,其真菌属分别是HZ1A(光板地0~20 cm)、HZ1B(光板地20~40 cm)、HZ2A(柽柳0~20 cm)、HZ2B(柽柳20~40 cm)、HZ3B(白茅20~40 cm)的2.23、1.74、1.24、2.18和1.38倍。此外,白茅群落真菌多样性高于柽柳群落和光板地。碱解氮对土壤真菌多样性和分布的影响最大,其与Knufia、旋孢腔菌属(Cochliobolus)、毛霉属(Mucor)、马拉色氏霉菌属(Malassezia)的相对丰度呈负相关,与其余真菌属的相对丰度呈正相关。

Abstract: Soil fungal diversity and the relationship between physical and chemical properties were studied using 454 high-throughput sequencing under bare land, Tamarix chinensis community and Apocynum venetum community. Total of 174 genera and 5 phyla were obtained in this study. The species and diversity of these fungi in different soil samples were different. Many kinds of fungi were obtained in A. venetum community, and HZ3A had the most fungi species. The genus of HZ3A was 2.23 times as much as HZ1A, 1.74 times as much as HZ1B, 1.24 times as much as HZ2A, 2.18 times as much as HZ2B, 1.38 times as much as HZ3B. In addition, soil fungal diversity of A. venetum community was higher than those of bare land and T. chinensis community. Alkali-hydrolyzable nitrogen (AN) had the greatest impact on distribution and diversity of soil fungal genera. AN was negatively correlated with the relative abundances of Knufia, Cochliobolus, Mucor, Malassezia and was positively correlated with the other fungi.

Key words: Yellow River Delta, 454 high throughput sequencing, soil fungi, fungal diversity, alkali-hydrolyzable nitrogen
