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。
Biolog-ECO microplate technique was used to study the function of microbial communities in the rhizosphere and non-rhizosphere soil of banana plants in three typical banded wilt disease sites in Banji, October and Xingpo, Diversity has been compared. The results showed that: (1) The functional diversity of soil microbial community in the affected area was significantly lower than that in the healthy soil; (2) The dominant carbon metabolism community in the soil and healthy soil was the same, both were amine / amino compound (3) The principal component analysis showed that the microbial community structure of soil microbial biomass was significantly different from that of October field plot in the four plots of spike, up slope, high and Guangzhou.
