摘　　要：为了探讨丛枝菌根(AM)真菌对大田甘蔗生长的影响,本研究进行了甘蔗大田接种AM菌剂的试验,初步分析其对甘蔗土壤及其微生物群落,以及对甘蔗植株生长的影响。结果表明:施AM菌剂能提高土壤中有效氮、磷和钾的含量;提高土壤的pH值,促进根系对根际土壤微量元素的吸收,特别是对Mn的吸收。没有施用化肥,仅施AM菌剂的处理土壤中的真菌数量极显著地高于其它处理;甘蔗大田施AM菌剂能增加株高、有效茎数和茎径,有效促进蔗株生长。To reveal the influence of arbuscular mycorrhizal （AM） fungi inoculation on sugarcane, sugarcane plants grown in fields were inoculated with AM fungi, and the soil property and microbes, the plant growth were investigated. The results showed that arbuscular mycorrhizal （AM） fungi enhanced contents of available nitrogen, phosphorus and potassium in soil, increased the pH value, and promoted the microelements absorption by the plant roots, especially Mn. The fungi in soil inoculated with AMF without fertilizer are significantly more than that of others. Arbuscular mycorrhizal （AM） fungi inoculation stimulated the plant growth, and increased the millable stalks, plant height and stalk diameter.
