摘要
为了明确烤烟新品系09011在广元烟区的最适留叶数,采用单因素随机区组试验的方法,通过设置不同留叶数处理,测定了各个处理烟株的农艺性状、经济性状以及化学成分。结果表明,烤烟09011的株高、茎围、叶长及叶宽均随留叶数的增多而有增加的趋势。同时,随着留叶数的增加,产量增加,但是上等烟比例呈现低—高—低的趋势,当留叶数为19片时,上等烟比例最高,为40.89%。此外,留叶数对中部叶和上部叶的化学成分含量影响不同,其中以留叶数为19片时烟叶的化学成分最为协调。
In order to find the optimumleaf numbers of new flue-cured tobacco line 09011 in Guangyuan tobacco area,a single factor randomizedblock test was conducted,and the agronomic traits,economic characters and chemical components of each treatment were measured.The results showedthat with the increase of leaf numbers,the height of plant,the stem diameter,the length and width of leaf and yield also increased.But the proportion ofthe superior tobacco leaves showed a low-high-low trend.When the leaf numbers was 19,the proportion of the superior tobacco leaves was the highest (40.89% ).In chemical composition,the effect of leaf numbers on the middle leaves and upper leaves was different.Among them,the chemicalcomposition was most coordinate when the leaf number was 19.
