| 摘 要： | 在大田条件下,研究驳枝和追施氮肥对早花烤烟成熟期叶片中水溶性总糖和淀粉含量的影响。结果表明：高施氮量抑制烟草叶片的水溶性总糖和淀粉积累,然而低氮促进了中部叶水溶性总糖和淀粉积累。

| Abstract: | The effects of Topping-Branching and Nitrogen Topdressing onwater-soluble total sugarand starchcontent of premature flowering tobaccoleaves during maturing stage were studied under field conditions. The results showed thatapplicationofmorenitrogen inhibited the accumulation of water-soluble total sugar and starch in tobacco leaves,however, low nitrogen promoted the accumulation of water-soluble total sugar and starch in the middle leaves. |
