摘　　要：烟草麻点病近几年来已严重影响烟叶的质量和产量,通过1990～1992年的广泛调查,病原物的分离、培养、接种以及麻点病与锰肥关系的研究,我们认为,该病为一种非侵染性病害。不良的气候条件及氮钾比例失调是诱因,在大量种植感病品种K326时,易造成大流行。其内在因素正在研究中。The yield and quality of Tobacco were heavily influenced by tobacco spot desease. Through plenty of investigation in 1990'- 1992, studying on the relation between the spot disease and manganese fertilizer, the isolation and culturing of pathogen, we considered that such disease was a noninfective disease. Bad climate condition and disproportion of nitrogen and potassium were predispositions of this disease. Epidemic might happen when susceptible variety K326 was planted in large area up to now ,its internal causal factor was under study
