大岩桐扦插——叶片扦插

#大岩桐 扦插是很普遍的繁殖方法,主要有枝插法、叶片扦插法,本文我们主要学习大岩桐叶片扦插,不仅可以快速繁殖大量的盆栽,而且还会很有成就感。

虽然本文主要说大岩桐叶片扦插,不过对于枝条扦插,我们也简单介绍下:

大岩桐块茎上常萌发出嫩枝,扦插时剪取2—3厘米长,插入细砂或膨胀珍珠岩基质中,注意遮荫,避免阳光趋向,维持室温18—20℃,15天即可发根。

下面开始进入正文——叶片扦插:

在大岩桐花落后(当然也可以不在花落后,比如网购掉的叶子也可以),剪取健壮的叶片,留叶柄1厘米,斜插入干净的河沙中(如使用珍珠岩和蛭石混合的基质土效果更好),叶面的1/3插在河砂中,2/3留在地表面,适当遮荫,保持一定的湿度,在22℃左右的气温下,15天便可生根(叶片两周不枯萎就是活了),出小苗后移栽入小盆。

当然大岩桐叶片扦插可选择的方法还有很多,比如把整片叶子带叶柄剪下,将叶柄悬泡在水里,冬天大概三个星期生根,夏天一星期左右就可生根,然后定植到水苔或者土壤中(疏松透气的花土)都可以。虽然大岩桐叶插生根很快,但是从定植到发芽,大概需要2-3个月,所以花友需要有点耐心。
