摘要 研究了不同氮素形态和用量对烤烟硝态氮含量的影响.结果表明:鲜烟叶硝酸盐含量随硝态氮比例和施氮量的增加而呈现出上升的趋势,其含量相应低于烤后烟叶,并与烤后烟叶的硝酸盐和亚硝酸盐含量之间均存在着极显著的正相关关系;烤后烟叶硝态氮含量与硝态氮比例和施氮量之间均呈显著或极显著正相关,硝酸盐和亚硝酸盐含量的变化规律在不同部位的烟叶间表现一致,二者之间的相关也达到极显著水平,但中部叶的硝态氮含量明显高于上部叶.此外,烤后烟叶烟碱和总氮含量与施氮量均呈极显著正相关,与硝态氮比例的相关则未达显著水平. Effects of nitrogen form and rate on nitrate nitrogen content in flue-cured tobacco were studied. The results showed that the increasing of NH4/NO3 ratio and the amount of nitrogen fertilizer used with in this experiment, the nitrate content of fresh leaf increased. The nitrate content of fresh leaf was lower than that ofcured leaf, and had highly significant positive correlation with the nitrate and nitrite contents of cured leaf.The NI-I4/N03 ratio and the amount of nitrogen fertilizer had significant positive correlation with the nitrate nitrogen content in flue-cured leaf, respectively. The change of nitrate content showed the same trend as that of nitrite content among the different leaf positions, but the contents of nitrate and nitrite of cutters were bigger than those of upper leave. In addition, the correlation coefficients of nicotine content and total nitrogen content in cured leaf were highly significant at 1% level with the amount of nitrogen fertilizer, and non-significant at 5 % level with the NH4/NO3 ratio, respectively.
