摘要
为探讨适宜临沧双江烟区烤烟主栽品种的最佳移栽期、追肥时间与留叶数,采用正交试验设计,研究了云烟87品种的移栽期、追肥时间和留叶数对烟叶化学品质和感官质量的影响。结果表明:移栽期是影响上部烟叶化学成分综合品质和感官质量综合品质的主要因子,对上部烟叶化学成分综合品质和中部烟叶感官质量综合品质具有显著影响,且获得最优品质的为A1水平,即5月1日移栽。留叶数和追肥时间分别对中部烟叶和下部烟叶的化学成分综合品质影响最大,且B2、B3水平和C2、C3水平即追肥时间为移栽后7、14 d及留叶数为18～21片时烟叶化学成分和感官质量综合品质最优。临沧双江烟区云烟87品种宜选择在5月1日移栽,移栽后7、14 d进行追肥,留叶数为18～21片较为适宜。
In order to find the suitable transplanting date,topdressing time and remained leaves,the effects of transplanting date,topdressing time and remained leaves on chemical and sensory quality of flue-cured tobacco were studied using orthogonal experimental design for the field experiment in Shuangjiang county of Lincang city.The results showed that transplanting date was the main influence factor to the comprehensive quality of chemical composition for upper leaves and sensory quality,and had significant effect on the comprehensive quality of chemical composition for upper leaves and sensory quality for middle leaves.The optimal level of transplanting date was A1on May first.Remained leaves and topdressing time were main influence factor to the comprehensive quality of chemical composition for middle leaves and lower leaves respectively.The optimal levels of topdressing time were B2and B3(7d after transplanting and14d after transplanting)and the suitable levels of remained leaves were C2and C3(18to21per plant).Comprehensive comparisons suggested that the transplanting on May first,topdressing time at7d and14d after transplanting and remained leaves of18-21per plant were suitable for the Yunyan87variety in Shuangjiang tobacco-growing region.
