仙人指栽培方法
仙人指的栽培仙人指俗称三月红。在国外适逢复活节开花,因此又称复活节仙人指,我国译名为亮红仙人指,下面就让我们来了解下仙人指栽培方法。
1.形态特征
三月红植株强壮,通常嫁接于三棱箭上,变态茎叶扁平肥厚,长椭圆形,边缘二三水波状,多分枝。嫁接后,第1节片即分生,成掌状扩散,多年生茎片老化后由绿色变浅褐色;茎长5~6cm,宽2~3cm,新节片较小,边缘稍带红纹,花瘦漏斗状,长3.5~4.0cm,成对或3朵并列于新变态茎顶端,萼黄绿,五棱肉质,花复瓣,12~13片往外卷曲,锐尖,外瓣长短不一,耐开,3年生植株可开花150~200朵左右,花期可达45天之久,红绿相间,极为鲜艳夺目。
2.繁殖方法
繁殖多采用嫁接法,用带根的三棱箭和接穗下端稍木质化,是快速生长的重要条件。嫁接时取20~25cm长粗壮带根三棱箭。花后是三月红的生长期,取稍木质化变态茎2~3节为接穗,用劈接法在三棱箭顶端正中劈下1刀,深1.0~1.5 cm,然后将接穗的稍木质处削成楔形,插进三棱箭的劈缝,用手稍扶上1~2分钟,放手接穗已固定,即可在弱阳光下晒上3~5分钟,然后植入盆中,放置通风处培育,勿让雨水淋伤口,以保证伤口愈合。然后按常规管理,来年3月即可红花朵朵。
3.管理要求
三月红忌烈日曝晒,花期可置室内观赏。立春后,花芽已形成,盆土不宜过干,以免落蕾,以上就是关于仙人指栽培方法的介绍。
