摘　　要：为了探讨不同施氮量对赣南烤烟生长发育及烟叶产质量的影响,明确烟区适宜的施氮量。以烤烟品种云烟87为材料,设置了5个不同梯度(120.0、127.5、135.0、142.5、150.0 kg/hm^(2))的氮肥施用量试验,采用随机区组设计,研究不同施氮量对赣南烟区烤烟农艺性状、产量、产值、品质的影响。结果表明,在一定施氮范围内,随着施氮量的增加,烤烟的茎围、有效叶数、产量、均价、产值及中上等烟比例增加,当施纯氮量超过142.5 kg/hm^(2),烟叶产质量降低。在施氮量142.5 kg/hm^(2)时,烟株长势、农艺性状表现优良、产量最高、内在化学成分较协调。In order to explore the effects of different nitrogen application rates on the growth and development of flue-cured tobacco in south of Jiangxi Province,as well as the yield and quality of tobacco leaves,and to clarify the appropriate nitrogen application rate in tobacco area.Fluecured tobacco variety Yunyan 87 was used as the material,five nitrogen fertilizer application experiments with different gradients(120.0,127.5,135.0,142.5 and 150.0 kg/hm^(2))were conducted.A randomized block design was used to study the effects of different nitrogen application rates on the agronomic traits,yield,output value,and quality of flue-cured tobacco in the southern Jiangxi tobacco region.The results showed that within a certain range of nitrogen application,with the increase of nitrogen application rate,the stem circumference,effective leaf number,yield,average price,output value,and proportion of middle to upper grade tobacco of flue-cured tobacco increased.When the pure nitrogen application rate exceeded 142.5 kg/hm^(2),the yield and quality of tobacco leaves decreased.At a nitrogen application rate of 142.5 kg/hm^(2),tobacco plants exhibited excellent growth vigor,agronomic traits,highest yield,and relatively coordinated internal chemical components.
