树冠是指树的哪里

植物图片 2019-10-21 11:07

树冠从字面意思理解就是树的最顶部，但更深层次的理解就是主枝干的最顶部为树冠，树冠是整个植株的一个重要部位，它为整个植株提供充足的光合作用，并且能为下部分提供更大的活动空间，树冠越通透整个植株就会长得越茂密。

树冠是指主干以上的部分

很多人只知道树冠，但不知道树冠是指树的哪里，其实可以从字面意思理解为树的顶部，但这不完整，正确的表达方式应该是指从根茎到第一根主枝干的最顶部称之为树冠，树冠为整个树提供光合作用，为下部分提供活动空间。

树的其它部位

1、树枝

树枝指的是主干或一些老壮的大枝上生的一些小枝条统称为树枝，树枝对整个树的意义非常重要，它的叶子，花和果实等都长在树枝上，树枝还是整个树形变化的重要部分，因为树枝可以剪出想要的形状。

2、树根

树根指的是树茎秆以下的部分，通常在土壤里面，根据树的品种根系会大小不一，根系是整个树的生命起点，没有根树就没办法存活，同时根还是为树干部分提供水分和养料的主要场所，可见根对整个树的一个重要性。

3、树皮

树皮通常指的是包裹在树茎外层的一种有一定韧性的皮，好比人类的皮肤，主要起到一个保护作用，并且很多种树的树皮都具有一定的药用价值，能够治疗和预防人类的一些疾病，对人的身体健康有着十分重要的作用。
