摘　　要：不同施氮量及基追比对烤烟生物学性状影响较小,但不同施氮量及基追比对团棵期农艺性状影响较大,对现蕾期和平顶期农艺性状影响不显著,对平顶期有效叶数影响较大。本试验中高施氮量的T2、中施氮量的T3和低施氮量的T7表现较好。在施氮量为6kg/667m2时,产量、产值和上等烟比例有随着追肥比例增加(50%-100%)而降低的趋势。在低施氮量3kg/667m2的条件下,追肥比例较高的T7和T8表现较好,施氮肥应该以追肥为主,基肥为辅。推荐当地的施肥应该降低氮肥用量,控制在4-6kg/667m2,同时氮肥后移,适当加大追肥比例。Nitrogen Application and Dressing Ratios on Tobacco biological traits less affected, but larger amounts and different nitrogenbased recovery ratio on the rosette stage agronomic traits, the impact on the budding peace on top of agronomic traits was not significant, on effective number of leaves topped a greater impact. In this experiment the high amount of nitrogen T2, T3 in the amount of nitrogen and a low amount of nitrogen T7 performed better. In the nitrogen rate of 6kg / mu, the yield, production value and fine tobacco ratio has increased along with supplemental proportion （50% -100%） and decreased. Under conditions of low nitrogen rate 3kg / acre, a higher proportion of T7 and T8 dressing better performance, nitrogen fertilizer should be the main base fertilizer supplement. Recommend local fertilizer N rate should be reduced, controlled 4-6kg / acre, while after postponing, appropriate to increase the proportion of top dressing.
