摘　　要：通过田间试验,研究了施氮量和留叶数对红花大金元生长发育、产量和质量的影响。结果表明,施氮量和留叶数以及其互作效应对烟株的农艺性状和经济性状影响显著。施氮量90 kg/hm2,留叶数18～22片的处理田间长势强,经济性状优;施氮量45～90 kg/hm2时,烟叶水溶性糖含量较高,总氮、总植物碱含量适宜,化学成分协调,感官质量较好,香气质、香气量、余味、总得分都较高。综合评价结果表明,在中低施氮量水平下(45～90 kg/hm2),单株留叶18～22片时红花大金元在湖北利川的产质量表现最佳。The effects of nitrogen rates and the number of leaves remained on plants on growth,yield,value and quality of flue-cured tobacco Honghaudajinyuan were studied by field experiments.The results showed that the effect of nitrogen rates,leaves remained,and their interaction on agronomic and economic attributes were significant.The reducing sugar content,total sugar content,total alkaloid and other chemical composition in tobacco leaves between treatment were significantly different at the 0.05 level.Considering the agronomical character,value,coordination of chemical compositions and the results of flavor quality,the best quality was found at 45-90 kg/ha nitrogen rates and 18-22 leaves remained per plant.
