| 摘 要： | 通过田间试验研究了有机无机氮配比对烤烟生长及产质量的影响。结果表明,与常规烟叶相比,有机态氮和无机态氮的比例为1∶1时烟叶前期生长较慢,但后期生长加快且略好,成熟采收早,并可使整个大田生育期略微提前;产值、上等烟比例、中上等烟比例分别提高3.4%、15.4%、3.1%,化学成分更协调。 |

| Abstract: | A field experiment was carried out to study the effects of the ratio of organic nitrogen to mineral nitrogen on the growth,yield and quality of flue-cured tobacco.The results showed that compared with the tobacco plants applied complete mineral nitrogen,the tobacco plants applied the 1∶ 1 ratio of organic to mineral nitrogen grew slower before vigorous growth stage,then grew quicker and better during its later growth stage,and that its leaf ripening and harvesting time was earlier,tobacco leaf production value,proportion of high class leaf,proportion of fair class leaf were increased by 3.4 %,15.4 %,3.1 %,respectively.The chemical composition of the tobacco leaf was more compatible. |
| Keywords: | Flue-cured tobacco Ratio of organic nitrogen to mineral nitrogen Growth Yield and quality |
