摘　　要：烤烟的移栽密度已成为影响烟叶产量和质量的重要因素。2012年度,以移栽株距为45 cm、行距110 cm和目前推广的移栽株距为50 cm、行距110 cm进行对比试验。试验结果表明,处理组的综合表现优于对照组:产值比对照提高5.15%,低次等烟降低了0.13%;烟株生长前期和中期,处理组的根密集层密度较对照组分别大3 cm和1 cm,在生长后期,处理的烟株较对照茎高高17 cm,茎围大4 cm。表明株距为45 cm、行距为110 cm的移栽密度适宜在邵阳隆回地区大面积推广。Transplanting density of tobacco has become an important factor affecting the yield and quality of tobacco leaves.In 2012,contrast experiment of different transplanting spacing of 45 cm × 110 cm（experimental group） and 50 cm × 110cm（control group） was carried out.The results showed that the comprehensive performance of experimental group was better than that of the control group.From the economic traits,the output value of experimental treatments increased 5.15%,low-grade tobacco reduced 0.13%,the density of root dense layer were 3cm and 1cm thicker,the stems was 17cm higher,and the stem circumference 4cm larger.It indicated that the transplanting spacing of 45 cm 110 cm was suitable for large area plant in Longhui,Shaoyang.
