摘要
为了掌握清香型烟叶不同生态区烤烟大田生长时间现状及影响因素,调查分析了云南、福建、贵州和四川省21个地（市）共261个乡镇的烤烟生产信息,系统比较了省际和地市间烤烟大田生长时间及构成因素的差异,并分析了影响大田生长时间的主要因素,结果表明：省际烤烟大田生长时间平均值差异不显著,这可能是由于各省烤烟大田生长时间变异系数的差异较大,其中云南省烤烟大田生长时间的变异系数最大,为5.7％,四川省的最小,为1.4％.不同地（市）烤烟大田生长时间差异显著,其中,红河的烤烟大田生长时间最长,为158 d,曲靖烤烟大田生长时间最短,仅130 d,楚雄、大理、昭通、丽江、玉溪、龙岩和南平等9个地（市）烤烟大田生长时间在135 ～ 145 d,保山、红河、临沧、三明、黔西南、凉山州等11个地（市）烤烟大田生长时间在145～ 155 d.省际及各省不同地（市）烤烟大田生长时间构成因素之间存在显著差异,其中营养生长期之间的差异最明显,云南省和福建省的营养生长期相差18 d.影响清香型烟叶不同生态区烤烟大田生长时间的主要因素为气象因素.
In order to grasp the current situation and influencing factors of fen-flavor tobacco field growth time in different ecology districts,the tobacco production information of 21 cities （including 261 towns） in Yunnan,Fujian and some place of Guizhou and Sichuan were analyzed.The differences of tobacco field growth time and its component factors between provinces and cities were systematically compared,and the main factors that affect the field growth time were analyzed.The results showed that （i） there was no significant differences between fenflavor tobacco production provinces in the tobacco field growth time because the difference of variable coefficients in each provinces are larger.The variable coefficient of Yunnan is 5.7 ％,which was largest and the variable coefficient of Sichuan is 1.4 ％,which was smallest.（ii） The differences of tobacco field growth time between different cities were significant.The longest time was 158 d in Honghe and the shortest was 130 d in Qujing.The tobacco field growth time of nine cities was between 135-145 d.The tobacco field growth time of eleven cities was between 145-155 d.（iii） there are significant differences in the component factors of tobacco field growth time between provinces and cities.Among these,the difference in vegetative period is quite obvious.The vegetative period of flue-cured tobacco in Yunnan was 18 d earlier than Fujian.In different ecology districts,the main factors that affect fen-flavor tobacco field growth time were meteorological factor.
