怎样避免枪刀药枝条徒长

Miss Chen

枪刀药是多年生常绿草本,属于爵床科枪刀药属,又叫红点草、雀斑草。枪刀药最早被看作是可以治愈刀伤、枪伤的草药,由于它的叶表密布着粉红和灰白两色的斑点,显得异常雅致宜人,因此人们把它引入盆栽世界。一般作小型盆栽,置于茶几、案头、装饰效果很好。

枪刀药的栽培管理比较粗放,除了要求湿润的空气以外,一般都能适应北方室内的环境,但常有徒长现象出现。首先是因为光照过多,枝条生长速度加快,使得节间变长,叶子稀疏,因而枪刀药应放在室内光照较暗处,避开夏季的直射光。其次,要求施肥,最好两三个月施1次,如果过量就会引起枝条徒长,影响美观。

另外,每年春季进行1次修剪,去掉拥挤的枝条,剪短过长的枝条,这样不仅可抑制徒长,还使植株变得整齐、丰满。剪下的枝条可用于扦插繁殖。
