摘　　要：在酸性赤红壤条件下,通过对大田甘蔗施用不同的化肥量和接种AM菌剂的试验,分析不同施肥水平对甘蔗根系内生真菌的影响。结果表明:甘蔗根系内同时存在两种内生真菌,即丛枝菌根(AM)真菌和深色有隔内生真菌(DSE)。通过对甘蔗根系进行染色观察后发现,凡是施复合肥的处理,在甘蔗根系中除了存在丛枝菌根(AM)真菌,还检测到较多的深色有隔内生真菌(DSE)的菌丝和微菌核。大田甘蔗施用AM菌剂影响土著AM真菌种群。To investigate the influence of fertilizer on endophytic fungus of sugarcane root in acid red soil,sugarcane plants were grown on different level of fertilizer and inoculated with arbuscular mycorrhizal fungus（AMF）. The results showed that there are two kinds of endophytic fungus in sugarcane root, the arbuscular mycorrhizal（AM） fungus and dark septate endophytes（DSE）. Through the dyeing observation of the root sugarcane, more septate hypha and microsclerotia of DSE were found besides AM fungus in the soil applied complex fertilizer than the others. The communities of soil AMF were affected by AMF inoculants.
