| 摘 要： | 通过田间试验对不同调控措施下烤烟开花时间进行了研究。结果表明,与对照相比,各处理均能推迟烤烟开花时间,增加有效叶片数,提高烟叶产质量;4个处理能明显提高叶绿素含量、NR活性和淀粉酶活性,增强烟株前期氮代谢,有利于个体形态构建,同时进入旺长期后可以使淀粉酶活性缓慢上升,抑制其过早进入生殖生长,使碳氮代谢更协调,从而达到控制和推迟早花的目的。 |

| Abstract: | A field experiment with four treatments and one check to study flowering time of flue-cured tobacco was conducted.The results showed that all treatments deferred flowering time,increased effective leaf number,yield,and output.The four treatments also increased remarkably chlorophyll content,NR and amylase activities,and N metabolism of early stage of tobacco plant,which was helpful for tobacco plant body building,and later in blooming stage,which could cause amylase activity increase slowly,thus deferred reproductive growth and early flowering. |
