Abstract Different fertilization modes were taken for the study of impacts on cucumber rhizospheric microbial communities.After the treatment of soil samples,effects on fungi,bacteria and actinomyces were determined by dilute cultural method,nitrosbacteria and nitrifying bacteria,denitrifying bacteria were determined by most probable number(MPN)method,DNA sequence diversity of bacteria were determined by PCR-DGGE molecular marker technology.The results showed that rhizospheric fungi and actinomyces were mostly impro...
