| 摘 要： | 通过对三个供肥水平N：P2O5：K2O：CaO的比例处理L＝1：2：0：2，处理S＝1：2：3：1，处理H＝1：2：5：1和三个烤烟品种：K326、红花大金元、V2的两因素田间试验，结果表明：（1）随着叶龄增加，叶片钾钙含量呈下降趋势，钾钙吸收系数则呈上升趋势。（2）钾效应表现为红大＞K326＞V2，钙效应表现为K326＞红大＞V2。（3）维持较高钙吸收系数的品种其光合色素含量较高，生育期较长。根系活力较强，具较高的总糖、总挥发碱。

| Abstract: | Three Different ratios of Potassium to Calcium were applied to three flue cure tobacco varieties. Under uniformly applied pure N90Kg/ha and N: P 2O 5 =1:2,three Different ratio treatments of K 2O to CaO are that: L is 0:2,S is 3:1,H is 5:1 .The trial showed: (1) with the aging of leaves , the potassium and calcium content in leaves took on down trend, but the absorption coefficient of potassium and calcium went up. (2) There are difference in the effect of potassium and calcium to varieties.The effect of potassium to varieties is: Hongda >K326>V2. The effect of calcium is: K326>Hongda>V2. (3) The varieties with higher absorption coefficient of calcium has higher pigment content, longer growth stronger vigor of root., nigher total sugar and total volatile alkali in harvest leaf. |
