中文摘要	[目的]探索旱地烤烟的适宜种植密度,为指导其大田生产提供科学依据。[方法]以湖南省安仁县为例,研究了不同种植密度（15 0001、6 5001、8 0001、9 500株/hm~2）对烟株的生育期和生长、烟叶产量和质量的影响。[结果]种植密度对烟株生育期的影响不大。随种植密度的增加,叶面积系数和株高增加,烟株茎围变小,节距变长。不同种植密度对烟叶产量和质量有显著影响。当种植密度为18 000株/hm~2时,烟株留叶数和烟叶产量均最高,分别为348 660叶/hm~2、2397.3 kg/hm~2。随着种植密度的增大,上等烟比例、中上等烟比例及均价均逐渐减少。烟叶产值随种植密度的增加呈先增后减的趋势,以18 000株/hm~2时最高（达26 801.85元/hm~2）。[结论]在安仁县特定的气候、土壤条件下,旱地植烟的最佳种植密度为18 000株/hm~2。
英文摘要	[ Objective] The research aimed to explore the suitable planting density of flue-cured tobacco in the arid area and provide the scientific basis for guiding its production in the field. [ Method] Taking Annren county of Hunan province as an example, the effects of different planting density （15 0130, 16 500,18 000,19 500plants/hm~2）on the growth period and the growth of tobacco plants, the yield and quality of tobacco leaves were studied. [Result] Planting density had little effects on the growth period of tobacco plants. With the increasing of planting density, leaf area index and plant height increased, the stem thickness became smaller and the node distance became longer. Different planting density had a significant effect on the yield and quality of tobacco leaves. When the planting density was 18 0130 plants/hm~2, the number of remained leaves in tobacco plants and the yield of tobacco leaves were beth highest,being 348 660 leaves/hm~2,2 397.3 kg/hm~2 resp. With the increasing of planting density, the proportion of superior tobacco leaves,the proportion of middle and superior tobacco leaves and the average tobacco price were all gradually decreased. The production value of tobacco leaves showed the trend of first increasing and then decreasing with the increasing of planting density and that with the planting density of 18 0130 plants/hm~2 was highest （26 801.85 yuan/hm~2）. [Conclusion] Under the specific climatic and soil conditions in Anren county, the best planting density of flue-cured tobacco in the arid area wasl8 0130 plants/hm~2.
