杜鹃花是很多花友都喜欢的花卉，它的颜色艳丽，花朵开放的时候也是挤在一起，花团锦簇的样子。但是养殖杜鹃花有时候会出现掉叶子，杜鹃花叶子一碰就掉怎么办呢!其实杜鹃花掉叶子多是由于环境不当、浇水不当和光照过多土壤碱化引起的，各种原因的解决方法不一样，一起来看看吧!

一、杜鹃花叶子一碰就掉的原因和解决方法

1、环境不当

有时候我们刚刚买回来一盆杜鹃花，还没怎么养护呢，就已经开始哗哗的直往下掉叶子。杜鹃花在花农处是养在温室中的，买回家之后就会不适应。这样的掉叶子现象其实是由于环境突变，造成的植株不适应新环境的现象。

解决方法：刚刚买回来的杜鹃花由于一直养在花农的处，必定不会适应家里环境。应该将植株尽量摆在阴凉环境，避免阳光照耀，然后保持通风状态，静养1～2个星期之后再来正常养护。

2、浇水不当

很多花友不知道杜鹃花叶子一碰就掉怎么办，其实有时候浇水不当也是会引起杜鹃花掉叶子。杜鹃花浇水过多会涝根，这样就不能输送养分，才会掉叶子。浇水太少就会造成植株缺水而掉叶子的现象。

解决方法：浇水过少及时补水就行了，但是浇水过多，就要将根部腐烂的部位剪掉，然后重新种植。后期的时候将一根木根插进土壤里，要是木棍沾有细土在上面，说明土壤湿润，浇水一定要少。但是木棍不沾土的话，就说明非常缺水，要及时补水了。

3、光照过多

杜鹃花喜光，但是要是长时间直接暴晒在阳光下面，就一定会出现脱水现象。这样一来，杜鹃花就会快速枯萎，然后它的叶子也会逐渐发黄、变得干枯，最后直接掉落。有时候暴晒过度，甚至会造成杜鹃花植株脱水死亡的现象。

解决方法：由于光照原因造成的植株掉叶子现象，最重要的是及时将杜鹃花移放到室内的阴凉环境中。这样一来就会避免继续脱水恶化。再浇上适量的水，补充杜鹃花植株由于暴晒造成的脱水情况。

4、土壤碱化

杜鹃花是一种名副其实的酸性植株，一定要养护在酸性土壤中。土壤的酸碱性的ph值最好保持在4.5～6之间，一旦土壤碱化之后，杜鹃花植株就会停止生长，落叶不止，甚至是死亡。

解决方法：杜鹃花由于土壤碱化造成的掉叶子现象，是一定要立刻进行换土培养的。换上一盆通气性好，同时又很有丰富的腐殖质的酸性土。换上的土壤可以用草炭土加上园土、红壤土和珍珠岩，以比例3:3:3:1进行混合就行。

二、预防杜鹃花叶子一碰就掉的方式

1、温暖环境

杜鹃花是一种生长在凉爽又湿润环境中的植物，在养殖杜鹃花的时候一定要注意环境温暖，不要过热或是过冷。最好将养护气温控制在12℃～25℃之间，夏天的时候将气温保持在35℃以下，然后尽量减少光照。冬天的时候气温保持在0℃以上，千万不要低于0℃，尽量多光照来避免冻伤。

2、适量施肥

很多花友为了让杜鹃花开的更加灿烂一些，会在杜鹃花生长期和花期前施加肥料。这是可以的，但是过量的肥料是会有肥害现象，尽量做到薄肥勤施。生长期施加氮肥助生长，花期的时候施加少量的稀薄液态肥即可。施肥最好是10天一次，连续3次就足量了。

3、保持湿度

杜鹃花喜欢湿润的环境，但是浇水稍多就会涝害植株的根部。所以我们尽量用喷雾喷洒植株，来保持杜鹃花湿润的生长环境。尤其是夏天的时候，不仅要喷洒杜鹃花植株，还要尽量扩大喷洒范围，保证植株周围环境都是湿润的。

4、换盆换土

杜鹃花施肥和浇水都很勤，这样以来盆土的营养会消散得很快，容易出现土壤过干，板结成块和碱化现象。我们尽量保持1～2年换一次盆土，花盆的材质以透气为主，最好的是紫砂盆，或者是便宜一点陶制花盆。土壤用草炭土加上红土壤，然后加上透水透气的砂土即可，养护后期还要经常松土，防止土壤干结。

通过上文的介绍，相信大家已经明白杜鹃花叶子一碰就掉的原因和解决方法了。其实只要按照上面的种植方法，你家的杜鹃花盆栽是一定不会出现掉叶子现象的。
