几种抑芽剂对烤烟腋芽的控制效果研究

为了筛选对烤烟腋芽有明显抑制效果的抑芽剂,对奇净、芽畏、抑芽敏、除芽通等4种药剂的抑芽效果进行了比较试验.结果表明:4种药剂对烤烟腋芽均有一定的抑芽作用,以药后4周的效果最好,各药剂处理抑芽率均在70%以上;药后6周除芽通和抑芽敏的抑芽率分别达81.44%和78.96%,抑芽效果分别为78.26%和76.81%,优于人工抹杈和其他药剂处理.

Study on control effects of tobacco sucker with tobacco suckercides

To control tobacco sucker more effectively, field experiments on inhibiting the growth of axillary buds were conducted with four tobacco suckercides such as Qijing,Weiya,Yiyamin and Chuyatong.The result showed that,each chemicals took effects on inhibiting the growth of axillary buds,and the control effect reach to the best with an inhibiting rate more than 70 percents after four weeks.The inhibiting rate of Chuyatong and Yiyamin were 81.44 and 78.96 percent respectively after 6 weeks,and the control effect rates were 78.26 and 76.81percent respectively,which was better than the treatments of hand-sucking and other suckercides.
