What is a tree and what is a shrub? How to distinguish them?

Arbor refers to a tall tree with an independent trunk from the root, and the trunk and crown are clearly distinguished. Woody plants with an upright trunk and a height of more than 6 meters are called trees, which are tall (generally 6 meters to tens of meters) and the trunk is obviously tall. According to its height, it can be divided into Wei Qiao (above 3 1m), Da Qiao (2 1-30m), Zhongqiao (1-20m) and Xiaoqiao (6- 10m). Woody plants with upright trunks and a height of more than 5 meters are called trees. Corresponding to the low shrubs, the tall trees that are usually seen are kapok, pine, magnolia, birch and other trees. Trees are divided into deciduous trees and evergreen trees according to whether they shed leaves in winter or dry season.

The height of the shrub is below 3-6m, and the trunk system has no obvious trunk (if there is a trunk, it is also very short), and it branches immediately after being unearthed, or on the overgrown ground. Its ground branches are erect (erect shrubs), arched (drooping shrubs), crawling on the ground (creeping shrubs), climbing other trees (climbing shrubs), and clustered below the ground or near the roots (tufted shrubs). If its height does not exceed 0.5m, it is called a small shrub; If the branches on the ground die in winter and germinate in the next spring, they become semi-shrubs.

Or subshrubs.

Distinguish between shrubs and trees

1 should be judged according to the structure of trees and the growth characteristics of branches. But some seedlings didn't die. Like osmanthus fragrans, the trunk is obviously a tree, but some small osmanthus fragrans are used as hedges, which should be regarded as shrubs. 2, generally more than three meters can be Screaming Trees, but in fact there is no obvious boundary, we must understand from life experience! 3. The tree is high (generally 6 meters to tens of meters) and the trunk is obviously tall. According to its height, it can be divided into Wei Qiao (above 3 1m), Da Qiao (2 1-30m), Zhongqiao (1-20m) and Xiaoqiao (6- 10m). Shrub trees are short (usually less than 6 meters) and have low trunks. It can also be seen from here that some trees are not absolute. As I said above, osmanthus fragrans may be small trees or shrubs. 4. Trees are classified according to the shape of plant stems: woody plants with upright trunks and a height of more than 5 meters are called trees. Corresponding to the low shrubs, the tall trees you usually see are all arbors, such as kapok, pine, magnolia and birch. Trees are divided into deciduous trees and evergreen trees according to whether they shed leaves in winter or dry season. Shrub: Woody plants with inconspicuous trunk and often many branches at the base are called shrubs, such as rose, dragon boat flower, azalea and peony.
