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 Mn 6 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,rhizo-fungic amount did not alter with antibiotic bacterial 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.
