茉莉花怎么繁殖
茉莉花怎么繁殖,家庭繁殖茉莉可用分株、压条和扦插3种方法。
(1)分株。如果养的茉莉是丛生型的,有4~5个以上的枝干,可在春天结合换盆进行分株。每棵以2~3个枝干为宜,若原株分枝少,也可选一枝生长旺盛的单独分出。分株时用枝剪或利刀将其剪断,分植于两盆中即可。
(2)压条。每年的5~6月间,选生长充实、长为40~50厘米的枝条,埋入土中5厘米深,埋入的枝条应有1~2个叶节,并用刀刻数处。经一个多月生根,两个多月上盆,让其在盆内继续生长,至第2年春天换盆时分植。以上两种繁殖方法, 成活率高,成株快,但繁殖数量少。
(3)扦插。扦插茉莉容易成活,只要温度在20℃以上,任何时间均可扦插,在家养条件下,一般在4月结合修剪进行。选生长粗壮的枝条,剪取3~4个叶节,长约10厘米,剪去下部叶片,只保留上部两个叶片即可。枝条剪取时,距上部叶节0.5厘米,下部距叶节0.3厘米。枝条剪好后,用蛭石或沙土做基质,根据插条的多少,选用大小合适的花盆进行扦插。
若选用高30厘米的花盆,装基质至2/3处,扦插后盖上玻璃,便于管理,也可用透明塑料袋保护。扦插3~5棵,可用小盆,用大口玻璃瓶或玻璃杯扣上,以后逐渐见光,并应注意透气。1个多月,新根长出,两个月便可上盆分植。口径20厘米的花盆,可栽4~5株,当年可见花,以上就是关于茉莉花怎么繁殖的介绍。
