摘　　要：[目的]探索重庆烟区烤烟适宜播种移栽期。[方法]以云烟87烤烟品种为材料,设置了5个不同移栽期,研究了不同移栽期对烤烟生长发育、产质量的影响。[结果]随着移栽期的推迟,移栽至现蕾期时间明显缩短;成熟期叶面积、株高、茎围及节距明显降低;产量、中上等烟比例、经济效益明显降低;移栽期Ⅱ和移栽期Ⅲ的烟叶化学品质最符合优质烟叶要求。[结论]综合考虑产量、经济效益以及烟叶品质等方面因素,认为重庆烟区移栽期应在5月10日前,有利于实现烟叶产量与品质协同提升。[Objective]To explore the suitable sowing and transplanting date of flue-cured tobacco in Chongqing tobacco area.[Method]Using Yunyan 87 flue-cured tobacco as material,five different transplanting dates were set up,and the effects of different transplanting date on the growth,yield and quality of flue-cured tobacco were studied.[Result]With the delay of transplanting date,the time from transplanting to budding period was obviously shortened;the leaf area,plant height,stem circumference and pitch of the mature period were significantly reduced;the yield,the proportion of middle and upper grade tobacco,and the economic benefit were significantly reduced;the chemical qualities of tobacco leaves at transplanting dateⅡand transplanting dateⅢwere most in line with the requirements of high-quality tobacco leaves.[Conclusion]Comprehensively considering factors such as yield,economic benefit,and quality of tobacco leaves,it is believed that the transplanting date of Chongqing tobacco area should be before May 10,which is conducive to achieving a coordinated improvement of tobacco leaves yield and quality.
