Abstract: To investigate the diversity of bacterial community structure in soil sample of 8 duck farms in Sansui Guizhou province, total DNA of the samples were extracted with kit, the bacterial 16S rDNA V3 variable sequence was amplified by PCR, the amplified sequence were separated by denaturing gradient gel electrophoresis (DGGE) technique, 43 bands were showed, number 7, 8 were relatively small.The DGGE fingerprint was analyzed by software Quantity One, and showed that the same duck farm similarities existed difference, while the similarity were higher than 50% of the majority.Results showed that the similarities between the sequences and sequences in GenBank were 90% to 100%, including α-Proteobacteria, β-Proteobacteria, Bacteroidetes, Actinobacteria, Acidobacteria and Firmicutes.

Key words: denaturing gradient gel electrophoresis; duck farm; soil; bacterial community structure
