君子兰不长新叶子是怎么回事

张祥明
04-09

一、养分不足

1、原因:只有在养分充足的前提下,君子兰才能够正常的生长叶片。如果在养护的时候,长时间没为它施肥。它获得不到足够的养分,自然也就无法长出新的叶片了。


2、处理方法:及时为它施肥。在冬春季节,每10天施一次;在秋天,每15天施一次;在夏天,暂停施加。另外要注意,在施加前需要先将之稀释一下。



二、阳光不足

1、原因:它的生长需要一定的阳光。如果在养它的时候,长时间把它放到阴暗的地方,它接受不到足够的阳光,无法合成足量的养分,就会难以生长新叶。


2、处理方法:将它转移掉有散光照射的位置养护。每天让它接受适量柔和、不强烈的阳光,保证期能顺利合成养分。



三、发生虫害

1、原因:有一部分害虫,会啃食植株中间的生长点,从而导致它无法长出新叶。


2、处理方法:用废弃的刷子,将植株叶子正面和反面的虫子都刷掉。然后再往植株以及花土上喷一些药液,杀掉残留的害虫。
