龙骨叶子发黄有可能是温度太高引起的,需要把它放在干爽的环境下生长;也有可能是浇水太多或者太少引起的,龙骨浇水大概一周一次;还有可能是施肥太多或是养分不足造成的,通常15天左右施肥一次;光照太强或太弱,也容易让龙骨叶子发黄。

1、温度太高

龙骨可以用来制作盆景,但是龙骨叶子发黄怎么回事;有可能是温度太高引起的,夏季的气温通常在35℃左右,但是龙骨最适宜生长温度在22℃,温度太高会让叶片水分流失的速度加快,出现龙骨叶子发黄情况;所以在养护龙骨时,需要把它放在干爽的环境下生长。

2、浇水不当

浇水太多有可能会造成龙骨叶子发黄,土壤中大量的积水,造成根系被浸泡至腐烂,最后龙骨无法呼吸,就会发生叶片发黄的现象;可以减少浇水的次数;浇水太少也会发生龙骨叶子发黄,因为根系无法吸取水分供给到叶片,叶片缺水就会发黄,给龙骨浇水大概一周一次即可。

3、施肥不当

给龙骨施肥太多会引起土壤肥害,进而龙骨根系就会腐烂,所以需要减少施肥的次数;当植株养分不足时,无法给叶片供给养分,也会让龙骨叶子发黄;龙骨通常15天左右施肥一次,在冬季应该一个月一次。

4、光照不适

在夏季光照比较大,当龙骨叶子被太阳暴晒后,叶片中的水分会大量的蒸发,就容易造成龙骨叶子叶子发黄;需要把植株移至散光处,或者为植株搭建遮阴的物件;当把龙骨放在阴凉封闭处,叶片不能进行光合作用,也容易引起龙骨叶子发黄,需要把它放在通风的亮光处。
