扦插以绿枝扦插为主,露地条件以5月和9月扦插为宜,温室内除了夏季均可。选择生长健壮、无病虫害的母株,将顶部花序剪除,以促其组织充实,一星期后剪取插穗。以扦插在草炭与珍珠岩(5∶1)的混合基质中成活率最高。先喷洒800倍甲基托布津溶液,对基质进行消毒,然后将把基质装入育苗平盘(深度约5厘米),抚平后轻轻压实,喷洒清水,浸透深约2/3基质为宜,放到一边备用。将插穗剪至长约5～7厘米,上端平剪,剪口距顶芽1厘米左右,下端斜剪成马耳形,只保留上部2～3片复叶,以利于伤口的愈合及生根。剪好的插穗浸在0.3%高锰酸钾溶液中消毒5秒钟,然后用 ABT2号生根
Cuttings to the main green cuttings, open conditions in May and September cutting is appropriate, in addition to the greenhouse in summer can be. Select a robust growth, pest-free mother plant, the top of the inflorescence cut to promote its tissue enrichment, cut cuttings a week later. The highest survival rate was achieved with cuttings in a mixed matrix of peat and perlite (5: 1). First, 800 times the thiophanate-methyl solution was sprayed on the substrate disinfection, and then the substrate into the nursery flat plate (depth of about 5 cm), gently smoothed, spray water, soaked for about 2/3 of the substrate as Should, aside aside. The cuttings cut to length of about 5 to 7 cm, the top of the flat cut, cut from the top bud about 1 cm, the bottom of the oblique cut into a horse-shaped, leaving only the upper 2 to 3 leaves, in order to facilitate wound healing and rooting. Cut the cuttings immersed in 0.3% potassium permanganate solution disinfection for 5 seconds, and then rooted with ABT2
