摘　　要：利用Biolog-ECO技术对不同育苗基质培育下的团花根际微生物群落功能多样性进行研究。结果表明:不同育苗基质的团花根际微生物群落功能多样性有显著差异,13#甘蔗渣堆肥用作团花育苗基质能显著增强微生物对碳源的利用,13#育苗基质培育的团花根际微生物总体表现较高的活性,并且根际微生物利用碳源的类型以糖类、羧酸类和氨基酸类化合物相对较多,如:D-半乳糖酸γ--内脂、D-甘露醇、D-纤维二糖、衣康酸、L-精氨酸、L-天门冬酰胺和L-丝氨酸。The microbial community functional diversity of rhizospheric microorganism of Anthocephalus chinensis cultured with different substrates were researched by applying the Biolog ECO method. The results show that the microbial community functional diversity in rhizosphere soil was significant difference with different substrates; the microbes in rhizosphere utilized more carbons with 13# sugarcane bagasse as the substrate, which the microbe in rhizosphere had relatively higher activity of metabolism than that of others treatments. Furthermore, the types of carbon source utilized by microbial community in rhizosphere were carbohydrates, carboxylic acid, and amino acid such as D-Galactonic Acid γ-Lactone, D-Mannitol, D-Cellobiose, Itaconic acid, L-Arginine, L-Asparagine, and L-Serine.
