迎光而生

植物喜光

我们都知道大部分植物喜光，比如向日葵.

但如何看出来一盆植物喜光呢？

part 1

迎光而长

当我们认真观察身边的多数植物时，会发现大多数植物都会向一侧生长，比如图1这盆月季花以及图2这棵沙果树等等，它们的花和叶子大多向着日照最多的一侧生长，这些植物都有着向光性这一共性。

图2

由此可见，喜光不仅让植物茁壮生长，同时也让植物上每朵花、每个叶片也争相向上生长在迎光的一侧。

part 2

日常的那些迎光植物

不仅是在室外生长的植物如此，在室内养的植物也是如此。

从图片中，我们可以看到，盆栽植物的多数叶片都会向着能沐浴到更多阳光地方的一侧生长，尤其放在窗边的植物，更为明显。

喜光并非所有植物的个性，但是植物的生存生长往往依赖于光，由此，我们也要分清喜光和需要光生长的区别。
