植物到底需要多少阳光

Microhard

去nursery买花的时候经常会看到标签上写着full sun， partial shade等，那他们具体的涵义是什么呢？
请看：
Full Sun: At least 6 full hours of direct sunlight. Many sun lovers enjoy more than 6 hours per day, but need regular water to endure the heat.

Partial Sun / Partial Shade: These 2 terms are often used interchangeably to mean 3 - 6 hours of sun each day, preferably in the morning and early afternoon.
- However if a plant is listed as Partial Sun, greater emphasis is put on its receiving the minimal sun requirements.

- If a plant is listed as Partial Shade, the plant will need some relief from the intense late afternoon sun, either from shade provided by a nearby tree or planting it on the east side of a building.


Dappled Sun: Dappled sunlight is similar to partial shade. It is the sun that makes its way through the branches of a deciduous tree. Woodland plants and underplantings prefer this type of sunlight over even the limited direct exposure they would get from partial shade.

Full Shade: Less than 3 hours of direct sunlight each day, with filtered sunlight during the rest of the day. Full shade does not mean no sun. There aren't many plants, except mushrooms, that can survive in the dark.

另外值得注意的是，阳光在你的yard里的同一地点一年四季光照时间可能会差别很大。

有人和我说，澳洲的地肥，插上就能长，我是不能苟同的。

种的好，不操点心是不行地。

有的时候需要给植物盖个遮阳棚，尤其是小的时候。

植物和人一样，如果给他一个适应的过程，是可以部分改良的！
国内早期的好多绿化设计，在开始的时候看了很不合理，但是经过一段时间的适应也能长的很好！
在深圳就有这样的例子，白蝴蝶、蜘蛛兰、肾蕨等喜阴植物被无知者种到了大太阳底下，半年一年后竟然也适应了，而且长的很好！
真是难以理解啊！

动植物都是这样，可以生活的地方要比最适合生活的地方大。有不少生物在自然界只在某些特定的环境下出现，但是被人带到完全不同的环境下也完全可以生活。不过不同的种类这方面的差别就大了，所以在不知道某个具体种类的适应性的前提下，还是尽量按照其自然状态下所需要的条件来照顾最好。
