摘　　要：采用均匀设计,研究烤烟施氮量、种植密度和留叶数对烤烟单叶质量、产量、产值、化学成分、香气成分和感官品质的影响。结果表明,在黔南烟区地膜覆盖栽条件下,以每667m2施纯氮7.0～7.5kg,密度1100～1200株(行距110cm,株距50～55cm),留叶数20～22片为宜。The method of uniform design was employed to study the effects of nitrogen rate, number of plants per area, and number of apparent leaves on single leaf weight, yields, output value, chemical components, aroma constituents and sensory character. The results showed that with film mulching in south Guizhou Province, the optimum harvest might be obtained in combination of nitrogen rate of 105.0-112.5 kg/ha, plant density of 16 500-18 000 plant/ha （ with row spacing of 110 cm and plant spacing of 50-55 cm） and apparent leaf number of 20 - 22 per plant.
