摘　　要：The continuous cropping of flue-cured tobacco in the major producing areas of Henan Province by designing questionnaire, fieldwork, enquiry and phone calls, mails, and other forms, the data were obtained then classified and analyzed. The results showed that the main planting areas of flue-cured tobacco were in Nanyang, Xuchang, Luoyang, Sanmenxia, Pingdingshan, and Luohe where were the major producing areas of succession cropping of flue-cured tobacco with percentage of 20%-40% for three years and over three years, and a few places up to 50%. Morbidity was common with wide distribution, and the main diseases were black shank, viral disease, and black rot. It proved that tobacco was not suitable for continuous cropping. Both of tobacco disease and pest rate and mortality significantly increased by more than 40% under continuous cropping for three years and over three years, and the yield and quality of flue-cured tobacco also decreased after continuous cropping. For many places, the tobacco yield started to decrease in the second year of continuous cropping, and after three-year cropping, the yield decreased in the range of 9%-24%. Continuous cropping for a long time would make a serious decline in the quality of tobacco, resulting in non-economic benefits. Therefore, in order to reduce the occurrence of diseases and economic loss in tobacco production, it is recommended to avoid continuous cropping, or to adopt appropriate measures to control tobacco continuous cropping obstacles in the unavoidable case.通过设计问卷、实地调查、询问及电活、邮件等形式对河南烤烟主产区的主要县／区的烤烟连作情况进行调查，并对调查数据进行了归类分析。从7个地市22个县（市、区）的调查结果分析得知，现今河南烤烟种植主要分布在南阳、许昌、洛阳、三门峡、平顶山和漯河等地，并且在主产区都有一定程度的连作现象，连作3a及以上的比例一般在20％～40％，有少数地区达到50％。烟草连作发病较普遍、分布较广的病害主要有黑胫病、病毒病和黑腐病等；同时验证了烟草不适宜连作。烟草连作3a及以上时，病虫害率及死亡率上升40％以上；连作后表现出产量、质量下降，大多数地区在连作第2年时产量开始下降，连作3a及以上时下降幅度为9％～24％。连作时间久会使烟叶质量严重下降，造成无经济收益。因此，为了减少烟草病害发生及产量、质量下降造成的经济损失，建议尽量避免连作，在无法避免的情况下应采用相应措施控制烟草连作障碍的发生。
