凤尾竹叶子发黄怎么办

2017-12-16
为照顾花友们的习惯,先说一下,本文说的凤尾竹是散尾葵(参照配图),凤尾竹作为大型盆栽,如果出现叶子发黄的情况确实比较棘手,一般来说叶子发黄形成的原因很多,不过主要是以光照、通风和空气湿度为主的环境因素为主。

尤其是北方,凤尾竹叶子发黄的情况较多,坦白的说,凤尾竹毕竟是南方植物,在北方是需要一定技术来打理的,我们要注意经常给叶子喷水增加湿度,夏季注意遮阴通风,日常浇水既要保持盆土微潮,又不能积水。

  凤尾竹水黄表现在凤尾竹的嫩叶安无光泽,老叶变化不明显,枝干逐渐细小,新梢发育萎蔫。 解决办法是将花卉放置于干燥通风的位置进行养护,等待风干一些的时候再将其放回盆土中。

凤尾竹浇水过少也会导致叶子发黄的现象,浇水过少,叶子边缘干枯,老叶从上到下逐渐发黄脱落,但是新叶的生长还较为正常。 注意浇水时多浇,浇透即可。

凤尾竹灼黄,受到强烈阳光的照射会引起叶片发黄的现象,表现为叶梢,叶缘出现干枯,叶片部分出现换色斑点。解决办法将受到灼伤的凤尾竹放置到阴凉干燥的地方即可。

凤尾竹肥黄,给植物施肥过多也会引起花卉发黄的现象,主要表现在植株叶子顶端出现褐色,一般叶面肥厚没有光泽,并且凹凸不平,老叶枯黄掉落。解决办法是停止对凤尾竹施肥,如果病发严重,可以用清水进行浇灌,并排水,逐渐降低肥料的浓度。
