摘　　要：为了进一步提高三门峡烟区上部烟叶的质量,采用120cm+60cm一垄双行的宽窄行距种植模式,以传统单垄种植为对照,通过调控株距进行不同种植密度研究。研究结果表明,一垄双行宽窄行能够促进烟株生长发育,不同种植密度间表现较大差异;综合上部叶在田间开片度、烤后烟叶的中上等烟比例、均价、亩效益和感官质量分析,在株距65cm条件下种植密度1140株/亩处理能够提高上部叶的整体质量。研究结果可为相似生态区域的上部叶生产提供借鉴。To further improve the quality of upper tobacco leaves in Sanmenxia tobacco area,the wide and narrow ridge with spacing planting mode of 120 cm+60 cm was adopted in this study.Taking the traditional single ridge planting as the control,different planting densities were studied by adjusting the plant spacing.The results showed that the wide and narrow ridge could promote the growth and development of the upper of tobacco plants,and there were great differences among different planting densities.Based on the analysis of the field opening degree of upper leaves,the proportion of top-grade tobacco in flue-cured tobacco leaves,average price,Mu benefit and sensory quality,the treatment of planting density of 1140 plants/Mu under the condition of plant spacing of 65 cm can improve the overall quality of upper leaves.The results can provide a refer⁃ence for upper leaf production in similar ecological areas.
