摘　　要：为探讨在高海拔区域植烟密度对红花大金元农艺经济性状、外观质量、化学成分和感官吸食品质的影响,采用田间试验的方法,在常规施肥的基础上开展了红花大金元不同种植密度试验。结果发现:当种植密度为86cm(窄行)～120 cm(宽行)×45 cm和87 cm(窄行)～120 cm(宽行)×40 cm(一垄双行)时,中上部烟叶的烟碱含量减低,烟叶内在化学成分的协调性提高,促进了烟株的田间生长发育,有利于提高烟叶的产量和产值;种植密度为115 cm×60 cm时,烟叶的上中等烟比例及均价较高;随种植密度的增加,上部烟叶的身份(厚度)降低,色度减弱。表明:种植密度与红花大金元烟叶产量呈正相关,宽窄行高密度处理有利于产量和经济性状的形成,种植密度对红花大金元中下部烟叶的化学成分影响较小,但密度增加有效降低上部叶烟碱含量。In order to study the influence of planting density in high ＇altitude localities to the growth, development, yield, value and quality of Honghua - Dajinyuan, field experiments are implemented and the density - field experiment of Hong- hua - Dajinyuan is also implemented under the same fertilizing volume. The results show： 120 （ Wide row） - 86 （ Narrow row）× 45cm and 120 （Wide row） - 87 （Narrow row） ×40cm （Double row per ridge） processes are benefit to growth and development of Tobacco plant in the field, and they can also help to improve the output and value of tobacco. Howev- er, 115 × 60cm process makes the highest proportions of top and middle class tobacco leaves and average price ; 20 （ Wide row） - 86 （Narrow row） × 45cm and 120 （Wide row） - 87 （Narrow row） × 40cm （Double row per ridge） processes are benefit to decrease the Nicotine content in the upper and middle tobacco leaf and improve the harmony level of chemis- try components inside tobacco leaf. With the increase of density, thickness and chroma of upper tobacco leaf decreases. Therefore, the process of wide -narrow row height density is benefit to improve output and value of tobacco leaf, improve the harmony level of chemistry components inside tobacco leaf and also increase the availability of tobacco leaf.
