摘　　要：以南江3号为供试材料,研究了3种不同种植密度对贵州余庆烤烟产量和质量的影响。结果表明:采用行距110 cm、株距60 cm的密度进行种植,能够有效促进烤烟株高和叶面积的平衡生长,增强其抗病性,增加单叶重,提高烤烟产量和产值,并影响烤烟内在品质,使其化学成分更加适宜和协调。In order to study the effects of different planting density on yield and quality of flue-cured tobacco, Nanjiang 3 was cultivated under three different planting densities. The results showed, 110 cmx60 cm planting density could effectively promote plant height and balance growth of leaf area, raise the disease resistance and the single leaf weight, improve tobacco yield and output value, influence internal quality. Therefore it was suggested the 110 cm×60 cm planting density was the suitable treatment for flue-cured tobacco in Yuqing area.
