| 摘 要： | 采用完全随机试验设计,研究水氮耦合对烤烟不同生育期外观长势及烟叶干物质积累的影响。结果表明,在灌水量60~80 L/株,施氮量3~7 g/株条件下,既可显著增加烤烟株高和茎围,促进叶片伸展,又可满足不同部位烟叶干物质积累的需要。

| Abstract: | Completely randomized design was conducted to determine the effects of water and nitrogen coupling on tobacco appearance and dry matter accumulation of tobacco leaves at different growing stages by designing different water and nitrogen treatments.The results indicated height and stem diameter of tobacco were enhanced remarkably,the leaves in different parts extended better with the range of irrigation 60-80L and nitrogen 3-7 gram for every tobacco.The treatment also satisfied the leaves′dry matter accumulating. |
