| 摘 要： | 通过大田试验,研究不同基追比和追肥时期对白肋烟干物质积累,总氮和烟碱积累动态的影响。结果表明:各处理烟株干物质积累速度在各生育期内均表现为高追肥处理大于低追肥处理,且基追比例相同时,在移栽后30d内,推迟追肥时期有利于烟株的干物质积累。白肋烟总氮含量随生育期的推进而降低,但随着追肥量的增加和追肥时期的推迟,总氮含量下降幅度减缓。烟碱含量随生育期的推进而增加,在栽后75d出现一个积累高峰,随追肥量的增大和追肥时期的延迟烟碱含量增加,其中上部叶烟碱含量变化幅度最大。 |
| 关 键 词： | 白肋烟 基追肥比例 追肥时期 干物质 总氮 烟碱 动态 |

| Abstract: | A field experiment was conducted to investigate the effects of supplemental proportion and top-dressing time on the dynamic change of dry matter,total nitrogen and nicotine content of burley tobacco.The results showed that the speed of the accumulation of dry matter of tobacco plant in high top-dressing proportion treatment was higher than that in low top-dressing proportion treatment in the whole growth duration,and at the same top-dressing proportion,in 30 days after transplanting,postponing top-dressing ... |
| Keywords: | burley tobacco supplemental proportion top-dressing time dry matter total nitrogen nicotine dynamic |
