以烤烟品种K326为试验材料，通过田间试验研究一年两熟条件下水稻、黑麦草、菊苣、红薯4种前茬作物对烟株生长及烟叶化学成分的影响。结果表明：前茬作物为水稻的烟株田间长势明显优于其他处理，烟叶化学成分也比其他处理更为协调。前茬作物为菊苣和红薯的烟株田间长势差别不明显，前作为红薯的烟株烟叶钾含量比其他处理低。前茬作物为黑麦草的烟株田间长势最差，且烟叶化学成分协调性不如其他处理。

Effects of different preceding crops,rice,ryegrass,endive and sweet potato,on growth and chemical components of flue-cured tobacco were studied by field experiment with flue -cured tobacco variety K326 as material. The results showed that growth potential of tobacco in field with rice as preceding crop was evidently better than that in other treat-ments,and coordination of chemical components in tobacco leaves showed the same trend. When the preceding crops were endive and sweet potato,growth potential of tobacco had not significant differences. When the preceding crop was sweet po-tato,potassium content in tobacco leaves was lower than other treatments. When the preceding crop was ryegrass,growth potential of tobacco was worst and the coordination of chemical components in tobacco leaves was worst.
