小苍兰怎么安全过冬
小苍兰怎么安全过冬,小苍兰性喜气候温和、湿润清爽环境,要求光照充足,不耐寒霜,越冬温度不得低于4℃,生长适宜温度15~20℃。通常中秋栽种,冬春季生长开花,人夏休眠。要求疏松肥沃、富含腐殖质、通透性强的沙质培养土。
盆栽小苍兰宜选大小一致的球茎5~7个,为保持花期株姿整齐匀称,应将旁侧的小仔球取下另行种植,然后用加肥培养土,下垫少许碎蹄片做底肥,栽在头号桶盆或菊花桶盆中,株距摆匀,深浅一致,覆土盖过球茎顶端2厘米厚,注意重茬不可使用原盆旧土。
小仔球可种植在苗盆或播种箱内,株行距2厘米左右。栽苗先在室外背风向阳湿润环境露天养护。霜降前人室或放南向封闭阳台,初入室温度不宜过高,夜温在5℃为宜,以后逐渐升温保持15℃左右,注意通风换气防止烟尘污染。
光照要充足,水分要适度,经常保持盆土及环境清洁湿润,不可干旱或积涝,致使叶梢干枯,花开不好。每10天追施充分腐熟的稀薄有机液肥1次,或与0.1%磷酸二氢钾和尿素混合溶液交替施用。因花梗细弱,抽出时可用细竹签绑扎支撑,元旦、春节期间即可开花。若从8月至翌春2月分批栽培新球茎,即可自元旦延续至“五一”开花。,以上就是关于小苍兰怎么安全过冬的介绍。
