    摘要:

    为了研究土地利用方式对酸性红壤丛枝菌根真菌(arbuscular mycorrhizal fungi, AMF)群落的影响,调查了酸性红壤4种土地利用方式 (草地、玉米、花生和大豆) 下非根际和根际土壤AMF群落多样性和组成结构。结果表明:土地利用方式显著影响了AMF群落优势属球囊霉属(Glomus)和巨孢囊霉属(Paraglomus)的相对丰度,但是根际作用影响不明显。土地利用方式而非根际作用显著影响了AMF群落香农指数和物种丰富度,其中大豆地表现出最低的香农指数和物种丰富度。土地利用方式和根际作用都显著影响AMF群落组成结构,但是土地利用方式的作用强度明显高于根际作用。球囊霉属主要解释了不同土地利用方式之间的AMF群落组成差异。土壤pH是影响土壤AMF群落结构的最关键因子。因此,土地利用方式比根际作用表现出对酸性红壤AMF群落更大的影响,展现了土地利用变化在影响土壤AMF群落方面的重要作用。

    Abstract:

    In order to investigate the effect of land-use pattern on arbuscular mycorrhizal fungi (AMF) community in acidic red soil, the diversity and composition of AMF communities in the bulk and rhizosphere soils under four land-use patterns (natural vegetation, maize, peanut and soybean) were investigated. The results show that Glomus and Paraglomus are the two genera with the highest relative abundances in the AMF community in acidic soil. Land-use pattern significantly affects their relative abundances, but the effect of rhizosphere is not significant. The Shannon index and species richness of AMF community are significantly affected by land-use pattern rather than rhizosphere effect. Among the four land-use patterns, soybean field shows the lowest Shannon index and species richness. Non-metric multi-dimensional scale (NMDS) and permutation multivariate variance analysis (PERMANOVA) show that both land-use pattern and rhizosphere effect significantly affect AMF community composition, and the effect intensity of land-use pattern is significantly higher than that of rhizosphere effect. Similarity percentage (SIMPER) shows that the genus Glomus mainly explains the differences in AMF community compositions among different land-use patterns. Soil pH is the most important factor affecting soil AMF community structure. Therefore, land-use pattern has a greater effect on AMF community than rhizosphere effect in acidic red soil, demonstrating the important role of land-use change in influencing soil AMF community.
