为揭示长年烟稻复种连作种植制度对烤烟产量、品质产生的影响，定位调查了3个烟区20块不同连作年限烟田，对逐项指标进行了趋势分析和显著性评价。结果表明，在1~23年烟稻复种连作年限研究范围内，烟叶经济性状和主要化学成分与连作年限呈二次曲线兲系，烟叶经济性状在复种连作12年前后呈下降趋势，烟叶化学成分在复种连作14年前后协调性逐步下降，烟叶主要感官质量随复种连作年限升高而下降。烟稻复种连作10年后应安排必要的轮作倒茬，兊服长期复种连作对烤烟产质量带来的不利影响。

In order to reveal the effect of continuous and multiple cropping of tobacco-rice for many years on the yield and quality of flue-cured tobacco, 20 of tobacco field for different continuous cropping years from three tobacco growing areas were investigated. Trend analysis and significant evaluation were carried out with each index.The results showed that it was inquadraticcurve relationship between tobacco economic traits,main chemical composition and continuous and multiple cropping years during 1-23 years of tobacco-rice continuous and multiple cropping. Tobacco economic traits presented a downward trend after12 years of tobacco-rice continuous and multiple cropping.The coordination of tobacco chemical composition declined gradually after 14 years. The major sensory quality of tobacco leaves decreased with years of tobacco-rice continuous and multiple croppingincreasing. It suggeststhat in order to overcome adverse effect of continuous and multiple cropping onyield and quality of tobacco,the necessary crop rotationis requiredafter continuous and multiple croppingfor10 years.
