1992年春天,我组织学生进行植物扦插实践活动时,曾在盆土中扦插过一条无花果枝,居然成活了。当年在被扦插枝的顶芽萌发后长了一段不长的主干,1993年春,顶芽再度萌发,受顶端优势的支配,主干继续向上生长。为了抑制主干,使其控制在适宜于盆栽的高度,在主干距盆土面高达25cm时,将顶芽掐掉,迫使顶芽以下的腋芽萌发,结果在主干的不同部 In the spring of 1992, when I organized a student to practice plant cuttings, I had inserted a fig branch in the potted soil and actually survived. In the spring of 1993, the top buds germinated again, and the main stems continued to grow upwards when they were dominated by the apical dominance. In order to suppress the trunk and control it at a height suitable for potted plants, the top buds were brushed off when the trunk was up to 25 cm above the surface of the basin and the axillary buds below the terminal buds were forced to germinate, resulting in different parts of the trunk.
