Abstract

Abstract: To compare bacterial diversity and community structure of paddy-tobacco rotation soils in Sanming, Fujian, and to understand microbial diversity resources, bacterial phyla of different soil samples were analyzed. Bacterial 16S rDNA gene libraries of Jiangle sandy loam soil, Jiangle loam soil, Ninghua sandy loam soil and Ninghua loam soil were constructed to study soil bacterial diversity and community structure. The results showed that 11 phyla were detected in bacterial libraries, including Firmicutes and Proteobacteria. Firmicutes and Proteobacteria were the dominant species in the two samples of Jiangle soils, and the dominant species of Ninghua were Proteobacteria and Acidobacteria. The Shannon-Wiener index (H′ ) and Simpson′s diversity index (D ) showed that bacterial diversity of loam soil was higher than that of sandy loam soil. The results of 16S rDNA gene libraries indicated that high bacterial diversity was found in paddy-tobacco rotation soil, the results presented certain references for the preliminary understanding of the bacterial species and composition. At the same time, the study also provided a scientific evidence for making better use of the microbial resources in this area.
