君子兰缺乏营养元素的病态症状是什么?
君子兰是一种珍贵的室内观赏花卉。君子兰栽培容易,但若管理不当,将会导致有花不发,甚至植株生长不良。因此,合理施肥是栽培好君子兰的重要条件之一。
据观察研究,君子兰缺乏营养元素时,有如下表现:
缺氮时,植株生长矮小、细弱;老叶呈淡绿色,严重缺氮时老叶为黄色,并出现红色素,基部老叶逐渐自下而上死亡;新生叶、花和果实明显变小。
缺磷时,植物生长受到抑制,叶片变为暗灰绿色,杂有紫色素;叶片细长,基部叶片逐渐变黄枯死,茎短而细。
缺钾时,叶片出现黄色小斑点,叶尖端先变黄,然后沿叶缘向基部蔓延,并逐渐干枯而变为黄色,严重时叶脉的叶肉组织也会干枯死亡;植株矮小,节间短;病症首先发生在基部老叶上。
缺钙时,植物的根尖会受到破坏而死亡。根系易腐烂,幼叶不能伸展,呈线状,植株生长停滞。
缺硫时,植株缺绿,叶脉呈黄色,顶端的幼叶较老叶受害早;叶片细长,生长缓慢。
缺锰时,中上部叶片黄化,叶脉呈绿色,但叶肉呈黄色小斑点,严重时形成棕褐色小斑点,叶片变小。
为了防止君子兰缺乏营养元素病的发生,冬春两季对君子兰要采取加肥、增光、减水等措施。立秋以后是君子兰生长的黄金季节,每二十天左右可结合浇水追施一次稀薄的经发酵的饼肥水,这样即可满足君子兰生长的需要。
