氮素是对烤烟产量和品质影响最大的一个元素。烟株对氮的吸收、转化受施用氮肥的形态、数量、施用方法以及气候等多因子的影响。烤烟对不同形态氮肥的反映及其对产量、品质的影响尚未做过广泛深入的研究。据美国北卡大学,100%硝态氮和100%铵态氮对烤烟产量和价值的影响,<10%,并认为随着硝态氮施用比例增加,尼古丁含量降低。Rhoads
Nitrogen is one of the most important elements affecting the yield and quality of flue-cured tobacco. Tobacco plant nitrogen absorption and transformation by the application of nitrogen fertilizer morphology, quantity, application methods and climate and other factors. Flue-cured tobacco on the different forms of nitrogen fertilizer and its impact on yield, quality has not been extensive in-depth study. According to the University of North Carolina, the effects of 100% nitrate and 100% ammonium nitrogen on the yield and value of flue-cured tobacco are <10%, and the nicotine content is reduced as the proportion of nitrate nitrogen is increased.
