摘　　要：以云烟85品种为材料,采用大田试验研究了密度与氮素互作对烤烟产质量的影响。结果表明,在同等种植密度条件下,在一定范围内施肥量的增加会促使叶片长度增长;同等施肥水平条件下,种植密度对烤烟产量、产值有较大影响。综合经济性状、烤后烟结构比例、外观质量等指标,得出在凉山烟区按照1.20 m×0.55 m的株行距及施用纯氮90~105 kg/hm^2种植烤烟处理的烟叶质量较好,较接近"中棵烟"质量标准。Using Yunyan 85 as the experimental object,effects of density and nitrogen application amount on the yield and quality of flue-cured tobacco were studied.The results showed that under the condition of the same planting density,there was a positive effect of fertilization on the increase of leaf length in a certain range.Under the same fertilization level,planting density showed great impacts on the yield and output value of flue-cured tobacco.Considering the economic characteristics,structural proportion of flue-cured tobacco,appearance quality and other indicators,it could be concluded that the treatment of 1.20 m×0.55 m row spacing and 90-105 pure nitrogen per hectare in Liangshan tobacco area showed relatively good tobacco leaf quality,which was closer to the quality standard of Zhongke tobacco.
