摘　　要：为探索马里兰烟适宜的氮磷钾比例,在五峰县烟区进行试验,研究了氮磷钾比例对马里兰烟生长情况、产量和内在品质的影响。结果表明,当氮磷钾比例为1∶1∶3时,烟叶的经济性状最好,化学成分较适宜,烟叶评吸质量较好。在五峰烟区土壤中等肥力下,马里兰烟的氮、磷、钾最佳使用量分别为180、180、540 kg/hm2。To provide a scientific basis for further extension of Maryland tobacco in Wufeng county, the experiment was car- ried out to investigate the effects of ratio of N, P, K on yield and quality of Maryland tobacco. Results showed when the ra- tio of N, P, K was 1：1：3, economic characters of the tobacco was good with suitable chemical composition and the high sensory. Under medium soil fertility, the optimal use level of N, P, K was 180 kg/hm2, 180 kg/hm2, 540 kg/hm2 for Mary- land tobacco in the tobacco-growing region of Wufeng county.
