采用大田试验研究了包膜尿素和氮素基追比例（7∶3、6∶4、5∶5）对烤烟农艺性状及产质量的影响。结果表明,施用包膜尿素可以在一定程度上提高烟株有效叶数,提高烤后烟叶经济产量及其他经济性状。随氮肥追肥比例的适当增加,中部叶和上部叶总氮、烟碱和淀粉含量呈增加趋势;总糖、还原糖含量呈下降趋势;综合试验结果认为施以包膜尿素且氮素基追比例为6∶4时,烤烟经济性状较好,化学成分趋于协调。

The effects of coated urea and proportion of nitrogen basal and topdressing（7 ∶3, 6∶4, 5∶5） on Agronomic traits and yield and quality of flue-cured tobacco were investigated by field experiments. Results showed that the application of coated urea could increase the effective leaf number in a certain extent, and improve the economic yield and other economic characters of flue-cured tobacco.Appropriate increase in nitrogen fertilizer topdressing proportion, middle and upper leaves nitrogen, nicotine and starch content showed an increasing tr...
