What are the common differences between trees and shrubs for greening seedlings?
The tree is tall (usually 6 meters to tens of meters) with obvious tall trunk. According to its height, it can be divided into four levels: Weiqiao (more than 31 meters), Daqiao (21-30 meters), Zhongqiao (11-20 meters) and Xiaoqiao (6-10 meters).
The tree is short (usually less than 6 meters) and the trunk is low.
Shrubs are woody plants without obvious trunk. The plants are generally short, no more than 6 meters, and transverse branches begin to cluster from near the ground. They are all perennial. It is generally broad-leaved plants, and some conifers are shrubs, such as juniper. If the ground part withers during overwintering, but the roots still survive, and new branches continue to sprout the next year, it is called "semi shrub". For example, some Artemisia plants are also perennial woody plants, but die in winter.
Some shade tolerant shrubs can grow under trees. In some areas, due to the influence of various climatic conditions (such as windy and drought), shrubs are the main body of ground vegetation and form shrub forests. Mangroves along the coast are also a kind of shrub.
Because of their small size, many kinds of shrubs are mostly cultivated as horticultural plants and used to decorate gardens.
Trees are plants with wooden trunks and branches that can survive for many years. Trees are generally called trees, with obvious upright trunks. The plants are generally tall, and the branches are higher from the ground, which can form a crown. There are many kinds of trees. The four main parts of a tree are its root, trunk, branches and leaves. The roots are underground. A tree has many roots.
As the saying goes, there are also those who call larger shrubs "trees", such as pomegranate trees, tea trees, etc
