花卉爱好者在养植盆花时都会发现:直接从仙人掌、仙人球、山影拳、令箭荷花、大丽花母本上基部(结合部)掰下来的插穗比用器械从中部剪下的插穗进行扦插,生根快,成活率也高。笔者经多年实践验证:手掰插穗在别的花卉上也适用。比如月季经过修剪后,长出的分枝,用手从基部掰下的插穗进行扦插,愈合、生根也快;夏初将菊花抹头后,过十几天,即能长出7
When flower growers planted potted flowers, they found that cuttings cut directly from cactus, prickly pear, mountain shadow box, arrow lotus, dahlia mother’s base (junction) than cuttings cut from the middle with instrument, and rooted fast , Survival rate is high. The author after many years of practical verification: hand bark cuttings in other flowers also apply. Such as rose after pruning, the growth of branches, hand cut off from the base cuttings cuttings, healing, rooting is also fast; early summer daisy after the first ten days, that can grow 7
