▲整形修剪传统做法是在小苗10厘米高时或在4节处打头,促发侧枝。本人在栽培中发现,打头早的植株生长缓慢,比自然生长的晚开花2周左右,而且植株矮小,分枝开张角度小的品种成为丛生型,分枝开张角度大的品种株形匍匐,不利于花的悬垂。所以,要使金钟高悬,必须培养较大的株型,并且必须要有强健的主干。为此应改进整形修剪技术。早春扦插的小苗 ▲ Trimming the traditional practice of pruning seedlings 10 cm high or at the beginning of 4, to promote collateral. I found in the cultivation, beginning of the early plant growth slow, later than the natural growth of flowering about 2 weeks, and the plant is short, branches opening angle of small varieties become tufted, branches opening angle of large plant creeping, not Conducive to the drape of flowers. Therefore, in order to make the Admiralty hanging, we must cultivate a larger plant type, and we must have a strong trunk. For this reason should improve the plastic surgery technology.
