为了改善土壤微环境并优化微生物菌剂适宜用量，采用盆栽试验，设置4个处理，研究了不同处理对土壤关键酶活性和烤烟根系生长的影响，结果表明：T1、 T2、T3处理较对照（ CK）均不同程度地提高了土壤脲酶、蔗糖酶和过氧化氢酶活性，以T1处理对土壤蔗糖酶活性增加效果最为显著，T2处理对土壤脲酶、过氧化氢酶活性增加效果最为显著。施用微生物菌剂处理的烤烟根系活力均高于 CK，且以T 2处理效果最好。施用微生物菌剂处理的烤烟根、茎、叶干重、根冠比均高于CK，且以T2处理的处理效果最好。因此，T1、T2处理改善烤烟土壤酶活性效果较好，T 2处理改善烤烟根系活力和烤烟根、茎、叶干重、根冠比的效果较好，T 3处理次之。

In order to improve soil microenvironment and optimize the suitable dosage of microbial agents, we carried out pot experiments with four treatments to study the effects of different treatments on the activities of soil key enzymes and the root system growth of flue-cured tobacco.The results indicated that: in comparison with the control ( CK) , the treatments T1, T2 and T3 im-proved the activities of soil urease, sucrase and catalase to different extent, especially the treatment T1 had the most obvious effect on the increase in soil sucrase activity, and the treatment T2 had the most obvious effect on the increase in the activities of soil ure-ase and catalase.As compared with CK, three treatments of applying microbial agents enhanced the root activity of flue-cured tobac-co, and the treatment T2 obtained the best effect.The dry weight of root, stem and leaf, and the root-shoot ratio of flue-cured to-bacco in the treatments ( especially T2 ) of applying microbial agents were higher than those of CK.Therefore, the treatments T1 and T2 could better improve the activities of soil key enzymes in flue-cured tobacco field, and the treatment T2 could better increase the root activity, the dry weight of root, stem and leaf, and the root-shoot ratio of flue-cured tobacco, which was followed by the treat-ment T3 .
