首先要选栽矮生品种。于4～6月,剪取矮生品种的嫩梢扦插育苗,这是使盆栽大丽花矮化的内在遗传因素。其次要适时换盒。一般应在幼苗长有2～3片新叶、苗高15×20厘米和20～25厘米时分别进行换盆。结合换盆,适当剪掉一些根须,但不可使盆土松散。这样,通过控制根系生长来达到减缓地上部生长的目的。三要及时摘心。当幼苗高约8厘米时,留4片叶进行摘心,以促生分枝,控制长高。待分枝叶腋再生二次分枝时,须及时抹芽,培养成为四本大丽花,花期每枝开一朵花,共开4朵
First of all, we should choose the planted dwarf varieties. From April to June, cutting young shoots cuttings of dwarf varieties, which is to dwarf potted dwarf inherent genetic factors. Second, timely change box. The general should seedlings have 2 to 3 new leaves, seedling height 15 × 20 cm and 20 ~ 25 cm, respectively, when the basin. Combination of basin, cut some roots appropriate, but not to loose basin soil. In this way, by controlling the root growth to achieve the purpose of slowing the growth of the upper part. Three topping in time. When the seedling height of about 8 cm, leaving 4 leaves topping, in order to promote the growth of branches, control height. To branch axillary axillary regeneration secondary branches, the buds should be timely wipe, cultivate into four Dahlia, flowering branches open a flower, a total of 4 open
