| 摘 要： | 为探明不同的施氮水平对烤烟新引进品种NC297生长发育、产量及质量的影响,对NC297进行不同梯度的施氮量田间试验。结果表明:增加或减少氮肥用量对NC297的生长影响明显;各处理中,比常规施氮量降低10%(121kg/hm~2)的处理烟株在整个生育期长势良好,成熟落黄正常,内在化学成分较为协调,有利于提高烟叶的整体质量水平。

| Abstract: | The effects of different nitrogen application rate on growth,yield and quality of NC 297,a new introduced flue-cured tobacco variety,were studied to discuss its fertilizer requirement characteristics and physiological property for popularization of NC 297.Results:The nitrogen application rate has a significant effect on growth of NC 297.The growth vigor and maturity of NC 297 plants applied with 121kg/hm2 nitrogen application rate (90％ of the conventional nitrogen application rate) are well and normal during the whole growth period and its chemical components are harmony relatively,which benefits to improve its overall quality level. |
