风信子怎么水养?
风信子怎么水养,风信子又名洋水仙、五色水仙,其花色五彩缤纷、艳丽夺目,又清香宜人,既适合盆栽,又适应水养,近年来深受人们喜爱。
水养未经人工低温处理的风信子可在11月初进行,应选用特制的玻璃瓶,瓶内装水。然后选大而充实的鳞茎直立于瓶口处,不使其有空隙,基部少量或不浸人水中。
先将风信子放于冷凉的暗处(最好用黑布将瓶子罩上)促其发根,待发根后再移至半阴处养护。在室温18~20℃条件下,3月初开花。水养期过晚,会出现叶片短缩、花序发育不良的现象。经过人工低温处理的种球,水养期可提前或推迟;如温度适宜,水养后6~8周可见花。
网信子水养期间应2~3天换一次水(水温20℃左右的自来水),经常保持浅水层。为防止水质变质可加1~2块小木炭防腐。换水时从容器边缘缓缓注入,不能将根拔起,以防鳞茎移动将根折断,影响生长。
水养期主要依靠鳞茎贮藏的养分生长,一般不必追肥。如欲改善营养条件,促进鳞茎后期发育,可适当增施复合型化肥,浓度应严格控制在1%~2%左右。花谢后将鳞茎栽种在土壤中,待叶片枯死后再取出放阴凉处贮存,以上就是关于风信子怎么水养的介绍。
