摘要
采用均匀设计试验方法,研究烤烟施氮量、种植密度和留叶数对烤烟烟叶平均单叶重、产量、产值、化学成分、香气成分和评吸结果的影响。结果表明,在黔南烟区无地膜覆盖栽培条件下,以施氮量8~8.5kg/667m^2,密度1000~1100株/667m^2(行距为110cm,株距为55-60cm),留叶数20-22片,可获得较理想的烟叶产量、产值、农艺性状和内在品质。
The uniform design was used in tobacco cultivation experiment to study effects of nitrogen level, planting density and number of remained leaf on average single leaf weight, yield, output value, chemical components, aroma compounds, smoking quality. The results showed that the optimum yield, output value, agronomic characters and internal quality could be obtained under the caltivation condition of 8 to 8.5 kg/667m^2 of nitrogen level, 1000 to 1100 plants/667m^2 of planting density (110cm of row spacing 55 to 60cm of plant spacing), 20 to 22 remained leaves in open fields of Qiannan region.
