| 摘 要： | 为研究黄河三角洲盐渍土壤中植物根围AM菌根真菌多样性及影响多样性的因素,从东营孤东和孤岛油区采集碱蓬和柽柳植物的根围土壤,鉴定了4种土壤试样中丛枝菌根(Arbuscular mycorrhiza,AM)的群落组成。结果表明:球囊霉属(Glomus)是盐碱地中的优势种,同时还有许多未知真菌;考察不同盐碱度情况下菌根真菌群落结构差异,结果表明:碱蓬根围土壤中AM真菌的多样性高于柽柳,孤东根围土壤AM真菌多样性比孤岛高。相关分析表明,铵态氮含量与AM真菌多样性呈现显著负相关。

| Abstract: | In order to explore the Arbuscular mycorrhiza （AM） fungi diversity of the plant rhizosphere in the saline soil of the Yellow River Delta, four rhizosphere soil samples of Suaeda glauca Bge and Tamarix chinensis were collected from Gudong and Gudao oil fields in Dongying City for identification of the AM fungi communities. The results showed that Glomus was the dominant species in the saline soil accompanying with many unidentified fungi. The investigation of the mycorrhizal fungi community in different soil salinity showed that the AM fungal diversity in the rhizosphere soil of Suaeda glauca Bge was higher than that of Tamarix chinensis, and Gudong higher than Gudao. The correlation analysis showed that the ammonium nitrogen content had a significant negative relationship with AM fungal diversity |
