| 摘 要： | 试验结果表明:烤烟的最佳施氮水平为纯氮135kg/hm2左右,其产量和品质及经济效益最高,产量达2250kg/hm2、经济效益达5652.91元/hm2;烟叶品质在一定施氮水平范围内随着施氮量的增多呈上升趋势,但达到一定限度时则呈下降趋势;烟碱与施氮量呈正相关,还原糖含量则与施氮量呈负相关。 |

| Abstract: | The results of experiments showed that the output,quality and economic benefits reached to the tiptop(the output was 2250kg/hm2 and the benefit was 5652.91 yuan/hm2) when nitrogen application rate was about 135kg/hm2.The quality of flue-cured tobacco improved when nitrogen application rate increased in rational nitrogen rate range.The nitrogen application rate was positively correlated with the content of nicotine and negatively correlated with the content of reducing sugar. |
| Keywords: | Flue-cured tobacco Nitrogen fertilizer Output Quality Economic benefit |
