摘　　要：在烟苗大十字期对烟苗根部采取浸根(T1)、灌根(T2)及浸根+灌根(T3)3种方式施用侧孢短芽孢杆菌,分别于移栽后30、60、90 d测定烟草根系活力、土壤微生物种类及其数量、土壤酶活性、烟叶化学品质以及经济性状。结果表明:烟苗移栽后30~60 d,T1、T2、T3的烟草根系活力、土壤酶活性较不施用侧孢短芽孢杆菌均显著提升,T3的烟草根系活力显著提高39.49%,烟草根际土壤细菌和放线菌的数量分别显著增加40.51%、41.64%,真菌数量显著减少28.39%;T1、T2、T3的烟草中部叶常规化学成分均达优质烟叶标准,中上等烟比例及产值较不施用侧孢短芽孢杆菌分别增加19.51%、72.57%,中部叶化学成分较其他处理更趋协调。In the large cross stage of tobacco seedlings,the roots of tobacco seedlings were treated with Brevibacillus laterosporus by dipping root(T1),irrigation root(T2)and immersion root+irrigation root(T3),and the root viability,soil microbial species and quantities,soil enzyme activity,tobacco leaf chemical quality and economic traits were determined 30,60 and 90 days after transplanting,and the results showed that 30 and 60 days after transplanting,the root activity and soil enzyme activity of tobacco treated with T1,T2 and T3 were significantly increased compared with CK(without B.laterosporus).Compared with CK,the root viability of tobacco in T3 was significantly increased by 39.49%,the number of bacteria and actinomycetes in the soil of tobacco rhizosphere increased by 40.51%and 41.64%,respectively,and the number of fungi decreased by 28.39%.The conventional chemical composition of the middle leaves of tobacco with T1,T2 and T3 all reached the standard of high-quality tobacco leaves,and the proportion and output value of middle and upper tobacco increased by 19.51%and 72.57%respectively compared with CK,and the chemical composition of the middle leaves was more coordinated than that of other treatments.
