中文摘要:

采用免培养技术对河西走廊酒泉地区的原生盐碱土、次生盐碱土和农田土中的放线菌群落结构及其多样性进行分析.结果表明:河西走廊酒泉地区原生盐碱土克隆文库分归于19个OTUs,分属于微球菌亚目、丙酸杆菌亚目、棒状杆菌亚目、弗兰克氏菌亚目、假诺卡氏菌亚目和放线菌目未知类群;次生盐碱土克隆文库分归于14个OTUs,分属于微球菌亚目、丙酸杆菌亚目和放线菌目未知类群;农田土克隆文库分归于于7个OTUs,分属于微球菌亚目和棒状杆菌亚目;微球菌亚目是3种不同类型土壤中的共有种群,是原生盐碱土和农田土中的优势种群.多样性指数和稀释性曲线分析结果显示,3种不同类型土壤中放线菌种群丰富度为原生盐碱土〉次生盐碱土〉农田土;原生盐碱土、次生盐碱土的稀释性曲线均未趋于平稳,说明盐碱土中放线菌多样性比实际更加丰富.

英文摘要:

In order to more accurately understand community structure and diversity of actinomycetes in saline-alkali soil from Jiuquan area of Hexi Corridor, the community structure and diversity from three kinds of soil samples ( primary, secondary saline alkali soil and farmland soil) were analyzed using uncultured methods. The results showed that the 16S rDNA clone library of actinomyeetales from the primary saline-alkali soil belonged to 19 OTUs, Micrococcineae, Propionibacterineae, Corynebacterineae, Frankineae, Pseudonocardineae and unknown groups of Actinomycetales; the 16S r DNA clone library of aetinomycetales from the secondary saline-alkali soil belonged to 14 OTUs, Micrococcineae, Propionibacterineae, Corynebacterineae, Frankineae, Pseudonocardineae and unknown groups of Actinomycetales; the 16S rDNA clone library of farmland soil belonged to 7 OTUs, Micrococcineae, Propionibacterineae, Corynebacterineae, Frankineae, Pseudonocardineae and unknown groups of Actinomycetales; Micrococcineae was the common population in the three soils, and also was the dominant population in primary saline alkali soil and farmland soil. The diversity index and rarefaction curves analysis showed that actinomycetes species richness was in order of primary saline-alkali soil 〉 secondary saline-alkali soil 〉 farmland soil. The dilution curves of primary saline-alkali soil and secondary saline-alkali soil were not leveled off, which indicated the actinomycetes diversity in saline-alkali soil was more enriched than the actual. The rich and diverse actinomycetes resources in saline-alkali soil from Jiuquan area of Hexi Corridor provide important data on the actinomycetes ecology distribution research, exploitation and utilization in saline-alkali soil.
