摘要
在大田条件下研究了氮肥不同施用期对烤烟生长发育,烟叶产量及品质的影响。结果表明,适量基肥与分次追肥相结合有利于提高烟叶产量和改善烟叶品质,与全作基肥或1/3基肥加2/3追肥相比,烟叶产量、中上等烟比例、均价及产值均有不同程度的增加,烟叶中化学成分更为协调,内在品质较好。
The study of application date of nitrogen fertilizer in field indicated that an appropriate basal application with repeated top dressing could increase yield and improve quality of flue-cured tobacco, as compared with wholly basal application or a third of basal application plus two thirds of one-time top dressing.
