| 摘 要： | 通过溶液培养研究了不同钾钙镁供应对烤烟品种K326吸收钾钙镁的影响。结果表明:随着钾钙镁水平的提高,烤烟吸收钾钙镁的量加大;随着生育期推延,烟叶中钾钙镁含量均降低。当K∶Ca∶Mg=468∶240∶60(质量浓度比)时,烟叶中钾钙镁含量较适宜。

| Abstract: | The absorption of K,Ca and Mg by flue-cured tobacco cultivar K326 and the interaction among them were investigated by hydroponics.The results indicated that with the increasing of level of K,Ca and Mg in cultural solution,flue-cured tobacco absorption increased.With the growth of flue-cured tobacco,the contents of K,Ca and Mg in leaves decreased.When K∶Ca∶Mg was 468∶240∶60(mg·L~(-1)),the contents of K,Ca and Mg in flue-cured tobacco leaves were suitable. |
