通过对比不同打顶时期与α-萘乙酸棉球扎顶对烤烟成熟期的农艺性状、烤后烟叶化学成分以及产质量的影响,探寻烤烟打顶的最佳方式。结果表明:（1）随打顶时间的推迟,烤烟产量有略微的降低,均价、产值和上中等烟的比例有所增加,以初花打顶处理的烟叶上中等比例最高。同时期内采用α-萘乙酸棉球扎顶的处理上中等烟比例显著高于未采用α-萘乙酸棉球扎顶的处理,但对均价和产值影响较小;（2）适当推迟打顶时期,可以使各部位烟叶化学成分趋于协调,其中以初花打顶并配以α-萘乙酸棉球扎顶的处理最佳,钾含量更高,烟碱含量更加适宜。综合评价,在初花期打顶并采用α-萘乙酸棉球扎顶有助于提高烟叶的产质量,...

To explore the optimal way of tobacco topping,the effects of different topping stages and bandaging the top of tobacco plant after topping with cotton ball soaked with α-NAA on agronomic characters at maturity stage,chemical components in cured leaves,and yield and quality of flue-cured tobacco were studied. The results showed that:( 1) With the postponement of topping,yield of flue-cured tobacco showed slightly decrease,the average price,output value and the proportion of middle and superior tobacco leaves were increased,and the proportion of...
