| Abstract: | Isolation,identification and statistical analysis were made on microbes from four different types of soil：soybean field soil tillaged successive years（DD）,paddy field soil cultivated successive years（SD）,uncultivated original ecology soil（XYZ） and soil of farmed grain for green land（C）.The result showed that the soil of the Sanjiang Plain mainly contained dominant bacteria of eight genus.Distribution trends of these microbes in soil profiles are：surface layer（0～20 cm）,sub-surface（20～30 cm）,deep（30 cm or less）.Composition and relative density of microbes in different types of soil are significantly different,which clarified the species diversity of soil microorganisms. |
