摘　　要：烟草根黑腐病是一种世界性真菌病,曾给各主要种烟国造成巨大损失。为此简述了近20年来烟草根黑腐病在中国各主要种烟省份爆发流行的状况,并对此病害的病原菌、生物学特性、侵染和病症特征加以介绍,总结了土壤理化性质、土壤养分状况、根系分泌物和土壤微生物等土壤生境因子对该病病原菌存活、侵染、病害爆发的影响,提出通过加强田间管理、改进栽培策略、合理施用肥料、引入生物防治等措施,以改善土壤生境为目标,抑制烟草根黑腐病爆发。Tobacco black root rot once resulting in great loss was a worldwide fungal disease. This paper gave a concise introduction on the outbreak of tobacco black root rot in our nation recent years, and the pathogenicbacteria, biological characteristics, infection and symptom of this disease, and then summarized the effects of soil habitat factors, included soil physi-chemical properties, soil nutrient status, root exudates and soil microorganism, on tobacco black root rot. At last, we raised some procedures, such as improving field management and cultivation strategies, reasonable fertilization and biocontrol, to ameliorate soil habitat and control the disease.
