摘　　要：探讨不同氮磷钾施用量对烤烟红花大金元产量和品质的影响,为凉山烟区红花大金元的进一步推广示范提供科学依据。试验设N1(60kg/hm2)、N2(82.5kg/hm2)、N3(105kg/hm2)3个处理水平,采用正交L9(34)设计,田间调查了各处理烟叶的农艺性状、主要经济性状和质量。结果表明,各处理的产量、产值、均价、上等烟比例和上中等烟比例均有显著差异,处理N(82.5)P(105)K(210)的经济性状较好,烟叶化学成分较适宜,烟叶评吸最好。凉山烟区土壤中等肥力下红花大金元的氮磷钾最佳施用量为N:P:K=82.5:105:210。The objective of this study is to investigate the effects of N, P, K rates on yield and quality of flue-cured tobacco Honghuadajinyuan and to provide a scientific basis for further extension of Honghuadajinyuan in Liangshan. An orthogonal L9 （3^4） design with three N rates was employed for the field experiment. Agronomic attributes, major economical characters, yield, and quality of tobacco Honghuadajinyuan were measured. The results showed that significant difference existed between various treatments for yield, value, average price, ratio of high-quality leaf, ratio of high-middle-quality leaf. The tobacco leaves of treatment N（82.5）P（105）K（210） had superior economic characters, chemical composition, and the highest sensory evaluation value. Applying N, P, K at this rate could get optimum effect for Honghuadajinyuan under medium soil fertility in the tobacco region of Liangshan.
