杜鹃花叶子干枯怎么办

张祥明
2018-04-28



1、温湿度问题

具体来说,适合这种植物生长得气温为十五到三十度。而湿度,则是在百分之六十左右。若是脱离了这个范围,那么就会出现一些问题,比如叶子干枯之类。所以,看看哪些条件不符合它成长,就去调节它。

2、光线问题

光照过强,或者长期处于光照之下,会造成叶子干枯的问题,这是由于强烈的光将叶子烧伤了。这个很容易理解。不过,需要注意的是,长时间不让它见光也会造成同样的问题。若是它长期处在一个昏暗的角落里,见不着光,那么也会使叶子干枯,以后还会掉落。所以,针对这两种情况,我们得选取一个折中的办法。它喜欢半阴,所以将它放在散光照射的地方最好了。也可以根据季节进行调整,冬季的时候光可适当强些。等到天气渐渐回暖,可以稍微遮荫。

3、水肥

我们首先要知道,其根部的耐受力很不好。水分太少,供应不足肯定会导致叶变干枯。如太多,导致积水,那么根部会烂,然后叶子干。肥料也是一样,太多了就会烧根,接着叶子枯萎。所以,根据上述几种情况,首先得明确具体的缘故。然后,再改进相应的补水或是补肥的方法。注意及时浇水,但不能积水。肥料的浓度要尽量低些,量也不能太多。
