摘    要:利用15N示踪技术,试验研究了N肥不同用量和留叶数对烤烟烟叶N吸收、分布及烟碱含量的影响。结果表明,不同施N量及留叶数对烤烟生长发育、干物质累积、N素吸收利用分布及烟碱含量均有明显影响,N素吸收分布很大程度影响烟碱含量,烤烟吸收的肥料N约1/2分布于烟叶部分,且上部叶含量最高,烤烟N素营养对上部叶烟碱的形成及含量有很大影响,控制施N量及留叶数可一定程度降低上部叶N含量,进而影响烟碱含量。

关 键 词:烤烟  N肥用量  留叶数  烟碱

Abstract:By using the()~(15)N technique,the effects of nitrogen application and remained leaves on the N uptake and nicotine content of flue-cured tobacco were studied.The results show that there are observable effects of different nitrogen applications and remained leaves on the tobacco's growth,dry matter accumulation,N uptake and distribution,nicotine content.N uptake and distribution affect the nicotine content of tobacco,about half of the fertilizer nitrogen is distributed in the leaves of tobacco and mainly in higher position leaves of tobacco plant.Nitrogen nutrition affects the nicotine content of higher position leaves of tobacco,the control of the nitrogen application and remained leaves can decrease the nitrogen content of the higher position leaves,thus decreasing their nicotine content.
Keywords:Flue-cured tobacco  Nitrogen application  Remained leaves  Nicotine
