摘　　要：烤烟移栽时施入抗生菌芽孢杆菌株A03菌肥，研究抗生菌肥对植烟土壤和烤烟生产的影响。小区实验结果表明：施用抗生菌芽孢杆菌A03菌肥可明显提高烤烟根际细菌的数量，显著降低放线菌的数量，而对真菌没有影响。施用抗生菌肥能够提高烤烟对病毒病的抗性，圆顶期根际土壤中除Ca和Mg元素的有效性略有降低外，P、K、Cu、Zn、Fe和Mn6种元素的有效性均有不同程度的提高，提高幅度在16．57％～56．39％；烤烟杀青样和烤后烟中N和P的平均含量高于对照处理：烤烟亩产量比对照处理提高10．45％，产值提高11．22％，上等烟率、均价也高于对照和商品菌肥处理。Antibiotic bacterial fertilizer of Bacillus sp. A03 was employed when flue-cured tobacco transplanted in plots. Rhizobacterial amount considerably increased, while rhizo-actinomycetic amount significantly reduced, rhlzo-lungic amount did not alter with antibiotic Dacterial fertilizer compared to the control. In addition the resistance of tobacco against tobacco virus enhanced; the availability of 6 mineral elements in soil at tobacco toping stage increased by 16.57% - 56.39% except Ca and Mg, whose availability slightly decreased; the contents of N and P in de-enzyme and tobacco leaves at different growth stages and flue-cured tobacco leaves were higher; the yield and production value per 0.067ha with antibiotic bacterial fertilizer were 10.45% and 11.22% higher respectively compared to control. Furthermore first-class tobacco leaves proportion and mean price with antibiotic bacterial fertilizer were higher than those of control and commercial bacterial fertilizer.
