摘　　要：为了寻找适宜于寻甸县烤烟在最佳移栽期移栽时的最佳苗龄期,在寻甸县不同生态区进行小区试验,设6个苗龄时期:30天、40天、50天、60天7、0天8、0天,研究不同苗龄时期移栽对烟株农艺性状、烟叶产量及质量的影响.研究结果表明,在相同的播种期条件下,苗龄在70天移栽时,在产量、质量、内在化学成分、内在质量都比其它几个处理得好,其次是60天移栽的烟苗.寻甸县烤烟苗龄70天并在最佳移栽期移栽,这时期移栽的烤烟经济效益最高,过早或过晚移栽则会影响烟叶品质,降低烟叶的经济效益.In order to find the best period of seedling age at the best of transplanting period that suitable Xundian County transplanting flue-cured tobacco,experiments carried out in different ecological zones of XunDian,established six seedlings period: 30 days,40 days,50 days,60 days,70 days and 80 days,finding the impact on different strains of tobacco agronomic traits,leaf production and the quality during the transplanting seedlings.The results showed that in the same sowing conditions,seedlings age in 70 days better than several other in production,quality,internal chemical composition and the intrinsic quality,followed by 60 days.Xundian County within 70 days of flue-cured tobacco seedlings and transplanting in the best period,the cost-effective of flue-cured tobacco transplanting this period will be the most,too early or too late will impact the quality and reduce the economic benefits.
