Abstract：A pot experiment was conducted to study the effects of different exogenous bacterial fertilizers on tobacco rhizosphere soil microbial biomass and respiration rate under quinclorac harm.The results showed that:Compared with normal soil,inj ured soil microbial biomass carbon (SMBC ),microbial biomass nitrogen (SMBN ),microbial biomass phosphorus (SMBP ) and soil respiration rate (SRR ) significantly reduced.After using three kinds of exogenous bacterial fertilizers,compared with the inj ured soil,the tobacco rhizosphere SMBC ,SMBN ,SMBP and SRR elevated,and were higher than the normal soil.In conclusion,the treatment of different exogenous bacterial fertilizers improves the tobacco rhizosphere soil microbial biomass and respiration rate of the inj ured soil,in which the fertilizer 3 is the best.
