摘 要:为解决烤烟上部叶烟碱含量偏高问题,采用大田试验研究了不同株行距对烤烟生长和产质量的影响,结果表明:在相同行距(120cm)的情况下,随着株距的加大,对烟株大田生育期、田间农艺性状具有一定的影响,对产量质量具有较大的影响,随着株距的加大,产质量在不断的下降,对烟叶内在化学品质影响较大,烟碱以及中部叶的还原糖含量表现最为明显,烟碱含量随着株距的加大而增高。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.the effects of different planting density on the growth period and the growth of tobacco plants,the yield and quality of tobacco leaves were studied The results indicated that Planting density had leffects on the growth period of tobacco plants and agronomic traits and the yield and quality of tobacco leaves.With the increasing of planting 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
