采用盆栽试验，研究了在含有二氯喹啉酸土壤中施入外源菌肥对烟草根际土壤微生物量和呼吸速率的影响。结果表明，与正常土壤相比，二氯喹啉酸危害下土壤微生物量碳（SMBC ）、土壤微生物量氮（SMBN ）、土壤微生物量磷（SMBP ）和土壤呼吸速率（SRR）明显降低；采用3种外源菌肥处理后，与受害土壤相比，烟草根际土壤中 SMBC、SMBN、SMBP、SRR均升高，且高于正常土壤。不同外源菌肥处理改善了受害烟株根际土壤微生物量和呼吸速率，其中以菌肥3（生物有机肥）效果最佳。

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.
