如何避免水仙花“啞花”

有些朋友辛辛苦苦擺弄水仙,卻出現“啞花”,很煞風景。這種情況有四種原因:


  一是品種品質差,鱗莖過小,其營養成分不足。有些鱗莖雖然較大,但鱗莖盤乾枯,鬚根稀少。因此,水養水仙要選擇樁頭大、飽滿、結實的水仙頭。

  二是室溫過高,光照不足。最適宜的溫度為11℃攝氏度,且陽光充足。一旦氣溫過度,應灑水降低氣溫。

  三是水質差。水質差或長時間不換水,會引起水仙爛根而“啞花”。因此水仙花用水要求純淨、無污染,最好用井水或流動的河水,自來水則需存放兩三天後再用。

  四是水仙頭雕刻時,若過多地將鱗莖削去,會造成水仙頭自身養分流失。因此,水仙雕刻時下刀要淺,以防傷害花蕊,儘量多保留鱗莖片,保證有充足的養分,以利開花。
