摘　　要：为了探明微生物菌剂对大田烤烟的应用效果,以中烟100为供试材料,设置4个不同微生物菌剂用量处理,采用盆栽方式研究其对烤烟生长和叶片关键酶活性的影响。结果表明:1施用微生物菌剂促进了烤烟生长发育,T1、T2和T3处理烤烟株高、单株叶数、最大叶面积和茎围等农艺性状指标均高于对照(CK),尤其是烤烟生长中后期T2和T3处理的烤烟单株叶数显著高于对照(CK);2施用微生物菌剂提高了抗氧化类酶活性,降低了膜脂过氧化类物质含量。各处理相比,以T3处理的烟株长势较好,叶片SOD和POD活性最强,MDA含量最低,其对应的微生物菌剂用量(21.0 g/盆)效果最佳。In order to ascertain the application effects of microbial inoculants on flue -cured tobacco, with Zhongyan 100 as tested materials,the pot experiments with four different treatments were conducted to study the effects of different application amounts of microbial inoculants on the growth of flue -cured tobacco and key enzyme activities in leaves.The results showed that：① the growth and development of flue -cured to-bacco were promoted by applying microbial inoculants;the plant height,leaf number of single plant,maxi-mum leaf area and stem girth of T1,T2 and T3 treatments were significantly higher than those of the control （CK）,especially in the middle and late period,the leaf number of single plant under T2 and T3 treatments were significantly higher than that of the control （CK）.② The activity of antioxidant enzymes in flue -cured tobacco leaves were increased by applying microbial inoculants,and the content of peroxide substance in to-bacco leaves was reduced.Compared with the other treatments,the tobacco plants under T3 treatment grew well,had the highest SOD and POD activities and the lowest MDA content,so the best application amount of microbial inoculants was 21.0 g per pot for tobacco.
