长寿花,一般是指圣诞伽蓝菜,多年生肉质草本,株高10-30厘米,小花橙红至绯红色,临近圣诞节日开花,拥簇成团,花色丰富,是惹人喜爱的室内盆栽花卉。那么,长寿花多少钱一盆?什么时候扦插?怎样养殖?
一、长寿花多少钱一盆?
据浙江花木市场王女士介绍,长寿花的价格一般在5—10元一盆左右!
二、长寿花什么时候扦插?
长寿花在5-6月或9-10月进行扦插效果最好。选择稍成熟的肉质茎,剪取5-6厘米长,插于沙床中,浇水后用薄膜盖上,室温在15-20℃,插后15-18天生根,30天能盆栽。常用10厘米盆。如种苗不多时,可用叶片扦插。将健壮充实的叶片从叶柄处剪下,待切口稍干燥后斜插或平放沙床上,保持湿度,约10-15天,可从叶片基部生根,并长出新植株。
三、长寿花怎样养殖?
盆栽后,在稍湿润环境下生长较旺盛,节间不断生出淡红色气生根。过于干旱或温度偏低,生长减慢,叶片发红,花期推迟。盛夏要控制浇水,注意通风,若高温多湿,叶片易腐烂,脱落。生长期每半月施肥1次,也可以用”卉支”15-15-30盆花专用肥。为了控制植株高度,要进行1-2次摘心,促使多分枝、多开花。圣诞伽蓝菜定植后2周用0.2%比久喷洒1次,株高12厘米再喷1次。这样能有效地控制植株高度,达到株美、叶绿、花多的效果。在秋季形成花芽过程中,可增施1-2次磷钾肥。
同时,在圣诞伽蓝菜的栽培过程中,可利用短日照处理来调节花期,达到全年提供盆花的目的。
