摘　　要：为了确定烤烟最佳移栽时间,以秦烟96为供试材料,采用田间小区试验调查了移栽期对烤烟产量和品质的影响。结果表明,移栽期向后推迟,烤烟产量、均价、产值和中上等烟比例均表现出先升高后降低的趋势。移栽期改变对烤烟化学成分影响显著,且不同叶位存在一定差异。与对照相比,化学成分适宜程度因叶位而不同,移栽期延后,4个叶位,烟叶化学品质均先升高后降低;同时,腰叶、下二棚叶化学品质优于顶叶、上二棚叶。秦烟96在洛南烟区的适宜移栽时间为5月10日,适宜的移栽期有利于烤烟生长发育,进而提高烟叶产量和品质。A field experiment using Qinyan 96 cultivar was conducted to investigatetheeffects of transplanting dates on yield and quality of flue-cured tobacco.The results showed that with postponement of transplanting dates, yield, average price, output value and percentage of medium and superior tobacco increased firstly,then declined. In addition, there was a significant impact of transplanting dates on chemical components of flue-cured tobacco, effect andchange trend in chemical components varied with differences in leaf site. Compared with the reference of the high quality flue-cured tobacco leaves, suitable degree of chemical components existed difference in various leaf positions. With postponement oftransplanting dates of flue-cured tobacco, chemical quality of flue-cured tobacco from four leaf positions increased firstly and then decreased. And chemical quality of flue-cured tobacco from cutters and lugs was better than that from tips and leaf. All resultssuggestedthat optimal transplanting datefor Qinyan96 was 10th-May in Luonan, and appropriate transplanting datecanimprove growth and development of flue-cured tobacco, andincrease yield and quality of tobacco leaf.
