摘　　要：为探究施氮量与留叶数对南平烟区‘翠碧1号’生长及烟叶质量的影响,以‘翠碧1号’为材料,设计不同施氮量与留叶数的栽培试验,对‘翠碧1号’农艺性状、物质积累、氮素含量、烤后烟叶物理性状及化学成分等进行测定分析。结果表明:施氮量减少促进了烟株的生长发育,提高了叶长、叶宽、叶面积和干物质积累量;降低了叶片氮素含量;提高了B2F等级烟叶的还原糖、总糖含量,降低了烟碱、总氮含量,改善了上部叶内在化学成分的协调性。留叶数增加降低了烤烟叶长、叶宽、叶面积;在115 kg/hm^(2)施氮量下,留叶数增加降低了烤烟叶片氮素含量和氮素积累量,并且C3F等级烟叶的叶长、叶宽、叶面积随留叶数的增加先升高后降低,总糖含量则随着留叶数的增加而升高,感官质量的总体得分也随留叶数增加而提高;在98 kg/hm^(2)施氮量下,氮素含量和氮素积累量则随留叶数的增加先升高后降低,并且降低了C3F等级烟叶的单叶重、叶长、叶宽、叶面积、总植物碱、总氮、钾含量,但提高了还原糖、总糖含量。综合分析,在施氮98 kg/hm^(2)、留叶18片处理下,南平烟区‘翠碧1号’的烟叶品质较优,感官质量更佳。To explore the effects of nitrogen application rate and leaf number on the growth and leaf quality of‘CB-1’in Nanping tobacco-growing area,a cultivation experiment was carried out to detect the agronomic traits,biomass accumulation,nitrogen content,physical characteristics and chemical composition of cured tobacco leaf.The results showed that the reduction of nitrogen application rate promoted the growth and development of tobacco plants,and increased leaf length,leaf width,leaf area and dry matter accumulation.Reducing nitrogen application rate decreased leaf nitrogen content,increased leaf reducing sugar content and total sugar content of B2F grade,reduced nicotine content and total nitrogen content,and finally improved the coordination of internal chemical composition of upper leaves.The leaf length,leaf width and leaf area decreased with the increase of the leaf number.Under the nitrogen application rate of 115 kg/hm^(2),with the increase of leaf number,the leaf length,leaf width and leaf area of C3F grade increased first and then decreased,while the total sugar content increased,and the overall score of sensory quality increased.Under the nitrogen application rate of 98 kg/hm^(2),with the increase of leaf number,leaf nitrogen content and nitrogen accumulation increased first and then decreased,leaf weight,leaf length,leaf width,leaf area,total vegetable base,total nitrogen and potassium contents of C3F grade decreased,but reducing sugar and total sugar contents increased.Comprehensive analysis showed that under the treatment of nitrogen application of 98 kg/hm^(2)and remaining 18 leaves,the leaf quality of‘CB-1’was better in Nanping area.
