#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
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。

凤尾竹旱黄
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。

解决办法
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
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。
