虎尾兰的繁殖方法?
虎尾兰的繁殖方法,虎尾兰属生性十分强健,被人们视为几乎是不死的植物。虎尾兰少量繁殖时可进行分株。其地下根茎粗壮,分枝力强,每个分枝上的顶芽萌发后都能抽生新叶。分株时先脱盆,抖掉泥土,找出每簇叶片下面的根茎,用修枝剪把它剪下来另行栽种都能成活。
成活后根茎节部的不定芽很快就能萌发而抽生新的地下根状茎,使株丛不断扩大,一年后新生叶丛又能布满盆面。金边虎尾兰须采取分株繁殖法才能保证子株叶片同样具有金边的特性,如果采用叶插,其叶片的金边会消失。大量繁殖虎尾兰可采叶扦插。
虎尾兰叶插在春夏季进行,以5~6月为好,选充实肥厚的叶片作扦插材料,按5~6厘米一段截断,放在室内晾上2天。待切口干燥后直立埋入湿润的素沙,入土深2~3厘米,放在明亮的室内养护,保持25℃以上的室温。30天后先从切口处的髓部长出新根,然后抽生很短的地下根茎并抽生新叶,这时那段扦插的老叶并不枯萎,待新的叶丛长全后再把老叶剪掉。
除分株法和叶插繁殖外,还可结合春季翻盆换土时,将蘖芽从植株基部分离,2~3天伤口晾干后,另行插植,经25~30天后即可发根育成新株,以上就是关于虎尾兰的繁殖方法的介绍。
