Abstract：To explore the promoting effect of different Bacillus rhizobacteria and their complex bacteria on rice root,in this study,better promoting strains were screened by germination experiment,and effects of single bacterium and complex bacteria on rice root were evaluated by pot experiment.Results showed that Bacillus pumilus sp.(J),Bacillus megateriun sp.(R) and Bacillus subtilis sp.(K) bacterium suspension significantly increased radical length of rice seedlings by 161.2％,157.9％,110.5％ compared to control without bacterium suspension,respectively.In unsterilized soil,the promoting effect of K (LZP06) on rice root was better than other treatments,and root dry weights of rice seedlings were increased by 65.3％ compared to control.The promoting effects of (K + J) s and (K + R + J) s on rice root were better than other treatments in sterilized soil,and root dry weights of rice seedlings were increased by 57.8 ％,69.2％ compared to control,respectively.This study indicates that K (LZP06) bacterium suspension,complex bacteria (K + J)s and (K + R + J)s suspension can significantly promote the growth of rice root,and they can be used as candidate bacteria agents in microbial fertilizer production.
