摘要
利用Biolog-ECO微平板技术对尖峰、十月田、冲坡3个香蕉枯萎病典型患病样地和临高、广州2个健康样地的香蕉植株根际和非根际土壤微生物群落的功能多样性进行了比较研究。结果表明:(1)患病样地土壤微生物群落功能多样性明显低于健康样地;(2)患病样地与健康样地土壤微生物的优势碳代谢群落基本相同,均为胺/氨基化合物代谢群和氨基酸代谢群;(3)主成分分析表明,尖峰、冲坡、临高和广州4个样地的土壤微生物碳代谢群落结构与十月田样地明显不同。
Microbial community functional diversity of rhizosphere and non-rhizosphere soil was studied by Biolog-ECO micro-tablet technology in three typical plantations infected by banana fusarium wilt of JianFeng, Shiyuetian, Chongpo and two healthy banana plantations of Lingao and Guangzhou. The results indicated that: (1) The soil microbial community functional diversity in the diseased banana plantations was significantly lower than the healthy ones. (2) The soil microbial community of dominant carbon metabolism was basically same between the diseased banana plantations and the healthy ones. And their dominant community structures were amine / amide metabolic group and amino acid metabolism group. (3) Principal component analysis showed that the metabolic characteristics of the microbial community were significantly different between four plots of Jianfeng, Chongpo, Lingao, Guangzhou and Shiyuetian.
