| 摘 要： | 试验结果表明：对烤烟产量起主要作用的是氮肥用量，密度与留叶数的互作。在单产１８１７～２６２５ｋｇ／ｈｍ２的范围内，农艺措施组合方案为：施氮量５８．５～７０．９５ｋｇ／ｈｍ２，密度２０１３０～２０５２０株／ｈｍ２，留叶数１９～２１片／株

| Abstract: | The experimental results showed that nitrogen levels and interaction between the density and the number of reserved leaf were significant in yield.The yield of flue cured tobacco NC89 was as high as 1 817～2 625 kg/hm 2 with the treatment of the amount of the nitrogen application:58 5～70 95kg/hm 2;the density of plant:20 130～ 20 520 plants/hm 2 and the number of reserved leaf:19～21 leaves/plant. |
