[0002] Seedlings are tree seedlings with root systems and stems. All seedlings cultivated in nurseries, regardless of age, are called seedlings before they are planted. There are three types of seedlings: seedlings, vegetative propagation seedlings, transplanted seedlings, and bed-keeping seedlings. Seedlings can also be classified according to trees and shrubs. Generally, there are more tree seedlings in the north and more shrubs in the south. This is mainly due to the growing climate. During the growth process of seedlings, lush branches and leaves need to be pruned. The seedling pruning device is a device for pruning and arranging seedlings. It is mainly used for the renovation of various seedling shapes. The seedling pruning device is a basic device nowadays in various landscaping departments.
