Abstract:
Taking the sandy soil in Yinchuan interior desert as material,the effect of sandy soil bacterial diversity in different organic materials treatments(1.with 5% poplar chips mixed with soil;2.with 5% poplar chips mixed with soil and covered with willow branches on surface;3.with soil surface covered by wood chips) were studied,with no treatment as control(CK),the soil bacterial in defferent treatment were studied by the denatured gradient gel electrophoresis (DGGE).The results showed that under the treatments 1,2,3,the structure of bacterial community changed in different degrees.The abundance of community structure was highest in treatment 3,then in 2 and lowest in 1.The results of clustering analysis showed that,two groups were clustered.They respectively were CK and 3,which similarity was 63% and treatment 1 and 2,which similarity was 67%.One bacteria which had the 96% similarity with bacteria related to organic materials decomposition was isolated and identified.
