1、安徽农业科学,JournalofAnhuiAgri.Sci.2014,42(1):39—40,42责任编辑姜丽责任校对况玲玲不同留叶数对国产雪茄型晒红烟生长发育和产量品质的影响郭新枫(安徽中烟工业有限责任公司技术中心,安徽蚌埠2330oo)摘要f目的]明确不同留叶数对国产晒红烟叶片开展和理化性状的影响,以确定其最适宜的留叶数。[方法]4个处理留叶数分别为10、12、14、16片。[结果]晒红烟留叶数多少在其生长初期对其影响不大,但当烟株个体较大时,留叶数少的个体发育较好。此外,留叶数还直接影响着烟株的个体发育和
2、群体发育,并最终对烟叶的产量和可用性产生影响。晒红烟采收的叶数随着留叶数的增加而增加,株高、节距基本上随着留叶数的增加而增大,茎围减小,但叶长、叶宽并不呈一定的规律。烟叶的内在化学成分含量一般随着留叶数的增加而降低,但这种趋势有时候并不一定呈现固定的规律,如总糖、还原糖的含量就呈现相反的趋势。对晒红烟品质进行最终的判定,要从不同留叶数对晒红烟农艺性状、物理特性、化学特性、产量及产值等因素的影响进行综合分析。[结论]晒红烟留14片叶时内外在质量总体较好,要最终确定其最适宜的留叶数,还需进行多个年度的验证。关键词留
