不同芽畏浓度对烟草的抑芽效应研究

The research of bud restraining's effectiveness by different "Yawei"densities on tobacco

为了减少烟草腋芽生长造成主茎营养的无效消耗,促进主茎烟叶整齐生长,2006～2007年在广西农业职业技术学院烟草栽培试验地进行不同芽畏浓度对烟草的抑芽效应研究。研究结果发现:与清水处理(CK)相比,不同芽畏浓度处理能有效的抑制烟草腋芽生长,其茎围、叶面积平均提高13.12%、10.46%,烟叶产量平均提高12.57%,效果明显,其中以90倍稀释液处理的效果最为理想。可见,采用适宜浓度的芽畏抑芽剂是烟叶生产中一种可代替人工抹芽的比较理想的腋芽抑制生产措施。

In order to reduce the useless consumption of nutrition in main trunk by axiilary bud growth, promote the regular growth of leaves in main trunk. In 2006--2007 an experiment was con- ducted in the college about the bud restraining＇ s effectiveness and the results showed that comparing with pure water treatment, different ＂Yawei＂ densities could effectively constrain axillary buds, in- crease trunk round and leaf area by 13.12% and 10.46% ,leaves yield by 12.57%, and the effectiveness was obvious, among which, 1：90 diluent treatment could gain the best result. So to use suitable bud constrainer is a kind of ideal replacement for manpower bud-smearing in production.
