摘　　要：2003～2004年在广西靖西县进行了烟草“开片降碱灵”施用方法试验。试验结果表明:合理喷施烟草“开片降碱灵”,能显著促进烤烟上部叶增宽、增长;显著提高烤后烟叶产量和上中等烟比例;显著降低上部叶烟碱含量并能显著增加钾含量。其中,以打顶当天喷施1次效果最好;打顶后第10天喷施1次效果次之;打顶当天和打顶后第10天各喷1次效果最差。因此,该产品应在打顶后及早施用。The experimental results showed that ＂catholicon＂ application can considerably make upper leaves longer and wider and increase the leaf yield and enhance leaf quality. The nicotine content in leaf was lower and K content was higher. The application on topping day achieved the best result, in the 9th day after topping was second, and two applications both on topping day and in 9th days after topping received the worst effect. These demonstrated that tobacco was highly sensitive to the time and amount of ＂catholicon＂ application and it must be used as soon as possible after topping.
