琴叶榕叶子发黄枯萎的原因及解决方法

一、土壤碱化

土壤碱化，这是所以家庭养殖植物都会出现的问题，由于我们在给植物浇水时，绝大部分用的都是自来水，而自来水也被称之为硬水，长时间用硬水给植物浇水，土壤中便会积存大量的盐，便会造成植物黄叶枯萎。

解决方法：在日常浇水时可以用纯净水，若没有条件的，可以把自来水提前困几天，或是让太阳晒几天，然后在进行浇水，这样就避免了土壤碱化的问题。

二、施肥不当

在施肥过程中，营养没有达到均衡化，氮肥量过少或是根本就没有，便会造成植物黄叶枯萎。但有的花友也会一次性施大肥，这样很容易造成植物烧根，叶子就会出现发黄枯萎等情况。

解决方法：可以追加氮肥的施肥，但也不可一次过量施放，要施淡肥，可以增加施肥次数，这样才不会让肥料伤害到根部。

三、光照过强或过弱

琴叶榕对光照的适应性较强，在明亮的散射光下就能生长良好，如果夏天摆在阳光下暴晒，会造成琴叶榕叶子发黄枯萎；如果长期放置在光线不足的地方，会造成植株生长细弱。

解决方法：夏天应避免阳光直射，若摆在室外必须遮阴，冬天应当增加光照。适于半阴环境下生长，夏天要避免阳光直射，以免灼伤叶子，使叶子失去光泽。但光线太弱，植株生长细弱，所以必须给其较明亮的光线，以利生长健壮。

四、病虫害

病虫害的产生也会使其叶子黄叶枯萎。所以日常养护中，一定注意。而且最好定期清洁盆土。

解决方法：植株发病后要及时地移动到阳光充分、通风良好的地方，不要向叶面洒水，而且要把发病的叶子剪掉。剪除病叶时将带斑部分和部分健康组织一同剪掉，再喷撒一些杀菌液进行保护。

五、环境不适合

若刚换一个新的环境，植物的叶子便很容易黄叶。其实给植物换盆时，植物本身就会产生多种问题。

解决办法：只要按照正常的养护方式进行养护即可，同时注意不要让阳光直晒到它。若不是什么大的原因，就不建议花友们给植物随便换盆。

刚买回来的琴叶榕叶子为甚么发黄？

琴叶榕就是不喜欢常年开着空调的密闭空间，特别是一些空气较为干燥的地方，刚买的琴叶榕刚换到新的环境中养护，叶子很容易变成黄褐色，通常是从叶子边缘开始的。叶子从边缘开始变黄，接着整片叶子就开始枯萎，如果处理不当还会不断蔓延。

这个时候就要增加环境湿度，在周围喷水，保持通风和环境温暖。盆栽的琴叶榕要保持盆土微润不积水的状态，除了容器和土壤疏松排水好，也要注意浇水方法，一定要避免直接将水浇到叶子上，叶子暂时也不要喷水，容易造成黑斑病或茎腐病。

通过上文的介绍，我们了解到琴叶榕叶子发黄枯萎的原因及解决方法，大家首先要对琴叶榕黄叶的病因进行分析，再对症下药，这样才能让琴叶榕更好的生长。
