花卉的壓條繁殖

壓條法也是花卉繁殖的重要手段,多用於花木類的繁殖,即於接近地面的枝條基部堆土或將其下部變曲埋入土中,待生根後剪離母體,單獨成株。壓條法有下列幾種:

1、一般壓條法。將植株基部一二年生的枝條下部刻傷,彎曲放入挖好的穴中,枝條上端露出地面,埋土深度9~19釐米,將其固定在穴中,待生根後,即用於生根的下放切斷移栽。此法多用於叢生灌木、梔子、臘梅、夾竹桃等。

2、堆土壓條法。在植株基部堆土,生根後分離移栽即可。為增加繁殖數量,在休眠期間,於地上部約9.0~20.5釐米處截去上部,待新梢長至20.5釐米左右時即可堆土。移栽時間一般在深秋或初春。

3、高壓法。即空中壓條。將高處枝條刻傷,然後用竹筒、花盆、鐵罐、塑膠等套住傷口外部,並填以苔蘚、腐殖土等,保持其濕潤。待高壓處生根後,與原母枝分離栽植。

  此外,為促進壓條生根,還可採取刻傷法、去皮法、扭枝法等。於這些處理的同時,施以生長素效果更佳。

此法優點是成活容易,能保持原品種特行;切點是難於在短時間內獲得大量苗木。
