| 摘 要： | 为探索连作对烟株养分分布的影响,采用烤烟长期连作盆栽试验.结果表明,随着连作季数增加,下部叶中氮磷钾含量降低,上部叶中磷含量降低,上中部叶中钾含量增加;对同一处理的烟株,在连作6季时,能显著促进钾素的转移再利用,增加上部叶片对钾素的吸收积累. |

| Abstract: | The pot experiment was carried out in the long-term tobacco continuous cropping to probe the effect of tobacco continuous cropping on nutrient distribution of different positions of tobacco plants. The results showed that the N, P and K content in the lower leaves decreased, the P content in the upper leaves decreased and the K content in the upper and middle leaves increased with increase of continuous cropping number, and six number of continuous cropping could effectively promote the transfer and re-utilization of K element and improve K absorption and accumulation in the upper leaves of the tobacco plants with the same treatment. |
| Keywords: | tobacco continuous cropping nutrient distribution |
