龙骨花，又称量天尺，是一种长相特别，外表带刺的仙人掌科植物。很多人都喜欢把这种植物养在家里，可是遇到龙骨花叶子发黄怎么办。如果是正常发黄，只需摘除发黄的叶子即可;如果是浇水过度，要减少浇水的次数;如果是光照太强，要给予适度遮荫;如果是病虫侵害，就要赶紧使用药剂。以下针对不同的情况有不同的解决办法。

龙骨花叶子发黄的处理办法

1、正常发黄

龙骨花叶子发黄有很多种因素，碰到这种情况时不要心急，可能是正常现象。在龙骨花落叶的时候，它的叶子发黄是正常的。只需要把发黄的叶子摘除就好。

2、减少浇水

龙骨花适合在透水性好的沙壤土中生长，过度的浇水可能会让泥土中积水过多，根部透气性差，反倒不利于它的生长。所以在遇到龙骨花叶子发黄怎么办呢，只需要平均半月浇次水即可，夏冬两季依据气温控制水量。

3、减少光照

龙骨花适合在温暖湿润，光照适度的环境下生长。夏天的气温过高，光照过于强烈，也会使龙骨花叶子发黄。所以在阳光强烈的夏天，或者中午要进行遮光，可以搬进室内阳台即可。

4、少量施肥

过度的施肥也会造成龙骨花的营养过剩从而使叶子发黄。龙骨花在生长期每两月施一次氮肥，在深秋时节，可以在花盆边放30颗左右的复合肥。

5、加强灭菌

还有一个原因可能是你的龙骨花受到的病虫的攻击，从而造成叶子发黄。这个时候就应该注意要使用灭菌剂，可以使用氧化乐果进行喷洒。

结语:总之龙骨花的叶子发黄原因有以上五种，要找出它的病症才可以对症下药。相信有了这些方法，大家的龙骨花都可以茁壮成长。
