摘  要：
中国北方大豆连作问题日益突出并受到广泛关注,为了将AM真菌应用于连作土壤,缓解大豆连作障碍。本试验采用Nested-PCR-DGGE技术分析接种摩西管柄囊霉(Funneliformis mosseae)对3种连作年限3种品种大豆苗期根系AM真菌菌群结构的影响。结果表明,接种F.mosseae后,同一品种连作两年大豆根系中AM真菌的侵染率最高,同一连作年限KF16根系中AM真菌的侵染率最高;不同连作年限不同品种大豆根系中AM真菌菌群中均含有粘性球囊霉(Glomus viscosum)和未培养的球囊霉属(Uncultured Glomus);种植于连作2年土壤的不同品种大豆根系AM真菌的丰度值和Shannon-Wiener指数均高于连作0年和连作1年的。本研究揭示接种F.mosseae对连作1年、连作2年不同品种大豆苗期根系AM真菌菌群结构影响显著。

摘  要：
Continuous cropping of soybean(Glycine max) in north China is an increasingly prominent problemand attracting widespread attention. Arbuscular mycorrhizal fungi(AMF) are applied in continuous croppingsoil in order to reduce continuous cropping obstacles. In this study, Nested-PCR-DGGE technology was usedto analyze the effect of Funneliformis mosseae on community structure of AMF in three different continuouscropping soils for three soybean varieties at seedling stage. The results indicated that the infection rate of AMFwas the highest in the same soybean variety with two continuous cropping years after inoculating F. mosseae.The colonization rate of AMF was the maximum in KF16 in the same continuous cropping year. There were Glomus viscosum and Uncultured Glomus in the soybean varieties' roots at different continuous cropping years.The abundance value and Shannon-Wiener index of AMF of soybean roots with two continuous cropping years were higher than those with zero continuous cropping year and one continuous cropping year. It revealed that F. mosseae significantly influenced the community structure of AMF in different soybean varieties' roots of onecontinuous cropping year and two continuous cropping years at seedling stage.
