摘　　要：为了探究不同植烟密度对桃源烟叶生长发育和质量的影响,试验通过对比不同植烟密度下,旺长期和成熟期烟株的农艺性状及常规化学成分数据,进而分析得出植烟密度与烟草农艺性状和内在成分的相关关系。结果表明,减少植烟密度利于改善株高及叶宽,适当增加植烟密度有助于提升烟叶烟碱含量,对于化学成分的协调性有显著提升作用。试验证实,桃源县采用1200株左右的种植密度对于提升烟叶化学品质及产量有较为显著的作用。这对于当地烟叶种植密度的管理,获得到高质量、高品质烟叶提供参考。In order to explore the effects of different tobacco planting densities on the growth, development, and quality of Taoyuan tobacco leaves, the experiment compared the agronomic traits and conven-tional chemical composition data of tobacco plants in the flourishing and mature stages under dif-ferent tobacco planting densities, and then analyzed the correlation between tobacco planting den-sity and tobacco agronomic traits and intrinsic components. The results showed that reducing the density of tobacco planting is beneficial for improving plant height and leaf width, and appropriate-ly increasing the density of tobacco planting is helpful for increasing the nicotine content of tobacco leaves, which significantly enhances the coordination of chemical components. The experiment con-firmed that using a planting density of around 1200 plants in Taoyuan County has a significant ef-fect on improving the chemical quality and yield of tobacco leaves. This provides a reference for the management of local tobacco planting density and obtaining high-quality tobacco leaves.
