- Abstract
By using PCR-DGGE and redundancy analysis (RDA), this paper studied the variations of soil bacterial community structure during the intensive management of Phyllostachys praecox stand, and analyzed the soil factors affecting the diversity of the bacterial community. The results showed that after the transformation of paddy field into P. praecox stand, the Shannon and richness indices of soil bacterial community increased significantly. Long-term intensive management of P. praecox stand altered the community structure of soil bacteria, reflecting in the changes of main bacterial populations and the great decrease after an initial increase of the diversity indices of soil bacterial community. Soil pH, soil total nitrogen, and soil available nitrogen and potassium could explain 76-1% of the total variation of soil bacterial community, and soil pH showed the greatest effect though it was not significant, indicating that the evolvement of soil bacterial community under the long-term intensive management of P. praecox stand was the result of the synergistic effects of several soil factors.
