摘  要:
[目的]研究钾肥不同基追比及根部追钾时期对烟叶常规化学成分的影响。[方法]采用两因素随机区组设计,即钾肥基追比和追钾时期2个因素,通过田间试验,分析不同处理对烟叶还原糖、总糖、总氮、烟碱、钾等常规化学成分的影响。[结果]钾肥基追比例为3/5基肥+2/5追肥、灌根追钾时期为1次灌根追钾(团棵期)+1次打顶当天灌根追钾(2次各半)时,烟叶还原糖、总糖、总氮、烟碱含量相对较低,钾含量相对较高,烟叶内在品质协调,质量好。[结论]在当地烟叶生产中,采取该处理措施施用钾肥有利于优质烟叶的生产。

摘  要:
[Objective] The aim was to study effects of different base topdressing ratio of potassium fertilizer and topdressing periods on concentional chemical composition of tobacco leaf. [Method]By using two factors( potassium fertilizer base topdressing and periods) randomized block design,through field experiment,effects of different treatments on tobacco reducing sugar,total sugar,total nitrogen,nicotine,potassium were analyzed. [Result]Under the treatment of 3 /5 base fertilizer + 2 /5 topdressing,one time topdressing on roots with potassium fertilizer( resettling stage) + one time in topdressing day( divided evenly),tobacco reducing sugar,total sugar,total nitrogen,nicotine content were relatively low,potassium content was relatively high,the internal quality of tobacco was harmonious and quality was good. [Conclusion] In local tobacco production,the adopted measures for applying potassium fertilizer is conductive to high quality tobacco production.
