腊梅什么时候开花
腊梅什么时候开花,腊梅在6月份新梢木质化后进入花芽分化阶段,7~9月花芽分化完成并发育完全。要使盆栽腊梅多开花,开好花,一般应做好以下工作:
(1)合理施肥。腊梅喜肥,开花后应及时施足基肥。在花芽分化前后,要适当增施磷肥,一般可根外追施0.2%磷酸二氢钾2~3次,能促使花芽的分化和加快花芽的发育。
(2)适当修剪。腊梅的发枝力强,修剪在开花后枝萌芽前进行,先剪去枯枝、过密枝、病虫枝和细弱枝,然后将留下的一年生枝在基部2~3对芽处进行强短截,以促发粗壮的枝条,春天发芽抽枝后,留2~3片叶进行摘梢,促使萌发短壮花枝。
(3)适量浇水。腊梅有一定的耐旱力,但畏水湿,花芽分化时,应适当控制水分,以控制营养生长,促使花芽分化。但应避免盆土过干,不然叶片变得干白,反而影响花芽的形成。开花期间的浇水必须适当,不然水多了易引起落花落蕾,水少了则开花不整齐,以上就是关于腊梅什么时候开花的介绍。
