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,低施氮量促进了中部叶中水溶性总糖和淀粉的积累。Under field conditions,the effects of topping-branching and nitrogen topdressing on water soluble total sugar and starch content in leaves of premature flowering flue-cured tobacco during maturing stage were studied.The results showed that high nitrogen application inhibited the accumulation of water-soluble total sugar and starch in tobacco leaves,while low nitrogen promoted the accumulation of water-soluble total sugar and starch in middle leaves.
