摘要
研究了施肥量和留叶数对NX232生长发育、产量和烟叶化学成分的影响,结果表明：施肥量为165 kg/hm2和150 kg/hm2、留叶数18～20片/株处理的烟株田间长势强、经济性状优、烟叶化学成分较协调。综合评价结果表明,在江西信丰潮沙泥田种植NX232,中等施肥量水平下（150 kg/hm2）单株留叶20片时,NX232的产质、品质和产值表现最佳。
The effects of fertilizer application rate and remained leaf number on the growth, yield and leaf chemical components of flue-cured tobacco variety NX232 were studied by field experiments. The results showed that tobacco plants in the treatments of applying 165 or 150 kg/hm2 fertilizer and remaining 18-20 leaves possessed stronger growth potential, better economic characters, and more coordinative chemical compositions. Comprehensive evaluation resuhs showed that： when NX232 was planted in the alluvial loamy paddy soil of Xinfeng county in Jiangxi province, applying medium rate （ 150 kg/hm2） of fertilizer and remaining 20 leaves per plant could obtain the highest yield and output value, and the best quality.
