植物图片 2019-03-27 17:18

黄桷兰属于一种四季常绿的乔木类植物，通常在室外种植最高可以长到20米。它的花朵呈乳白色，看起来非常的优雅迷人，而且香气浓郁，非常好闻。所以把它作为盆栽在家种植的也不在少数。

一、黄桷兰叶子发黄怎么办

平时在我们养殖黄桷兰的过程中，经常会碰到一些问题。比如说黄桷兰叶子发黄怎么办？黄桷兰叶子发黑了怎么办?遇到这些问题我们首先要了解清楚它发黄或是发黑的原因，然后再对症下药。

1、施肥不当

黄桷兰是一种喜肥的植物，所以我们平常在给它施肥的时候就要注意一些问题。在施肥量上我们不能施的过多，也不能施的过少，施的过多会灼伤黄桷兰的根部，这样根部吸收不到营养，叶子也会吸收不到营养，那肯定就会出现叶子发黄的情况了。施的过少就会营养不良也会造成黄叶。那黄桷兰怎么施肥呢？

解决方法：给黄桷兰施肥我们应该遵循着少量多次的原则，而且在施肥的时候我们不要给它施以浓肥，应该把肥料按照说明稀释以后再施肥。而且最必须留意的是，不要看见了黄桷兰出现任何的问题，都认为是肥料不足的原因而盲目的施肥。

2、浇水不当

黄桷兰叶子发黄跟浇水也有一大部分的原因，有可能是由于浇水不及时造成干旱，也有可能是由于盆土积水不透气造成根部腐烂，这样就会造成黄桷兰的叶子发黑。

解决方法：我们在养殖黄桷兰的过程当中，要随时注意黄桷兰的盆土里面是否有积水，若果有积水要及时排空，保持土壤见干见湿的原则。在夏天高温天气时，应该每天都浇一次水，保持叶子的湿润度。

3、病害虫造成

在高温天气，有很多植物都很容易受到褐斑病的干扰，黄桷兰也不例外。黄桷兰如果发生褐斑病就非常容易造成叶子发黄枯萎，然后凋零的后果。那我们应该怎么去解决呢。

解决办法：一旦黄桷兰碰到这种病害，我们应该立即把叶子摘下并烧毁，以防感染其它的枝芽，再用0.2{bf}的退君特或代森锌喷洒防治。缺绿病注意增加土壤酸度，减少阳光直射，注意蔽荫，施肥不宜过浓。然后洒上石膏粉杀菌。

4、修剪不及时

我们在养殖黄桷兰的过程中，由于有时候枝芽太过茂密，我们有可能看到它的外观完好就不会去管它，可是正式这种心理为黄桷兰的逐渐发黄埋下了很大的隐患，有时候在它的植株里面的位置，会有几片由于各种原因造成的黄叶不易被发现，所以就慢慢的传染到其它的叶子。

解决办法：所以我们平时在养护黄桷兰的时候，不能只看表面，时常也要拨开外面的枝芽看一看里面的情况，如果发现烂叶、黄叶的情况就要及时的修剪一下，不仅能保持植株的漂亮，也能及时的修剪掉黄叶避免感染整棵植株。

二、黄桷兰怎么培育

我们要养好一盆黄桷兰，就必须要了黄桷兰的种植方法与注意事项。那么我们就要从土壤、浇水、施肥、气温、修剪这几个方面来入手了，只要掌握了培育黄桷兰的方式，相信养出一盆美丽的黄桷兰就不是难事了。

1、土壤

黄桷兰适合在酸性土壤的环境下生长，通常土壤的ph值为5.5—6.3最好。我们可以使用松针腐叶土5份、粗糠灰2份、粗沙2份3沤熟的厩肥2份来配置养殖黄桷兰的土壤，然后选择一个底部有小孔的花盆在底部铺上一些炉渣即可。

2、水分

黄桷兰属于肉质根，所以对水分的要求比较高。太干了会叶子枯卷，太湿了会烂根，然后就会有黄桷兰叶子发黄怎么办的问题了。在黄桷兰的花期，我们可以通过花瓣来分辨盆土的干湿度，如果花瓣向外扩张就说明水分不足，我们就要及时浇水了，浇水就要一次浇透。如果成花苞状，就证明湿度适合。

黄桷兰的浇水时间可以依据季节来，春天由于空气湿度高，不用浇太多次水。夏天气温过高所以就需要每天都浇水，浇水要选在傍晚这个时间。入冬以后，我们就要减少浇水量了，大概十天浇一次即可。

3、施肥

想要黄桷兰的香味浓郁，我们就要在施肥这个因素上多花点功夫了。从上文中可以看到，黄桷兰忌浓肥，所以我们施肥要先稀释。给黄桷兰施肥要保持“稀施、常施、傍晚施”的原则。我们可以使用人粪尿、豆饼水然后加一些鱼杂碎、烂虾、鸡内脏一些东西沤熟后，按肥水1:9的比例。三到五天施一次，这样长出来的花朵花香味浓。

4、气温

黄桷兰不适合在气温较低的地方生长，最低不能低于5℃，不然存活率很低。所以冬天我们就要把黄桷兰搬进室内养护，气温保持在5℃以上即可。虽说黄桷兰不耐寒，但也不能让它在特别高温的烈日下暴晒，所以夏天我们要对它进行遮阴养护。

5、修剪

修剪是一项必须进行的步骤，我们在家里种植盆栽，为的就是观赏还有净化空气。那如果长时间不对它进行修剪，那植物会长的毫无边幅，那黄桷兰怎么修剪呢？那如果黄桷兰长得过高，我们就要把它的顶枝剪掉。还有那就把一些阴枝、病枝、弱枝修剪掉就可以了。

通过上文的介绍，相信大家都知道了黄桷兰叶子发黄怎么办的解决方法，及其黄桷兰怎么培育，希望大家都可以养出美丽的黄桷兰。
