Abstract: Plastic pruning is an important part of the maintenance and management of gardening trees, so gardening shears will definitely be used. So what types of garden shears are used to prune flowers and trees? Generally, gardening shears are roughly divided into aerial shears, thick branch shears, gardening scissors, pruning shears, etc. Different types of gardening shears have different application ranges. Let’s learn more about the types and uses of gardening shears. 1. What types of gardening shears are there

1. Pruning shears

Using pruning shears to prune flowers and trees is to coordinate the reasonable growth of all parts of the flowers and trees, maintain the tree shape, promote flowering and fruiting, and prevent and control The main method of pests and diseases, and more importantly, the cuts are neat and will not easily damage the flowers and trees.

It can be used for pruning all year round. For example, during the growth period of trees in spring and summer, diseased branches, dead branches and thin branches can be cut off at any time, and leggy branches can be cut off or shortened. Before pruning, it is necessary to distinguish the growth direction of the branch buds and make correct choices. A branch usually has bud eyes on its left and right sides. If you want the branch to develop to the right, cut the branch short in front of the right bud eye that reserves the ideal length of the branch. Because the buds of trees have a top growth advantage, the buds at the top of the branches grow the fastest. After the new branches grow in the right bud eye, they will achieve the purpose of developing to the right, and vice versa.

Scope of application: pruning various small plants, pruning shrubs and fruit trees, etc.

2. Gardening scissors

Gardening scissors (branches) have rounded edges and are used to trim shrubs and plants. When pruning branches, the force used causes the upper cutting edge to gradually penetrate into the branches, and the lower edge plays the role of supporting the branches so that the branches will not break. In addition, branch shears are very labor-saving to use. General scissors have a retractable design, and the force arm can be adjusted to suit different users!

Yes, but before you start, you still need to make sure that the scissors are in a 90° vertical relationship with the plant (to prevent the embarrassment of making messy cuts), and try to keep the end of the blade as close to the plant as possible (also for the purpose of Labor-saving considerations), if you look carefully you will find that the blades and handles of ordinary scissors are not on the same plane and are designed to save labor based on the principle of leverage. It can be summed up in three words: fast, accurate and ruthless!

Scope of application: shrub pruning, grass pruning, etc.

3. Thick branch shears

Thick branch shears are also known as branch shears, strong shears, and strongman shears. The garden shearing tool can cut thick branches of 0-4 cm, similar to vise pliers, and is a must-have for large woody trees. The shape of the knife head includes straight mouth shape, meniscus shape or guillotine shape, and hand scissor shape. Although the quality of pruning shears is generally reliable, they should not be used to cut dry soft wood.

The two blades of thickening shears are different, one is sharp for cutting and the other is blunt and thick for squeezing, so the usage method is similar to that of pruning shears (pay attention to the cutting order of retaining and removing parts). However, during operation, you need to adjust the length of the arm according to the thickness of the branches and your own strength (most thick branch shears now have retractable designs).

Scope of application: fruit tree pruning, shrub pruning.

4. Aerial shear

Aerial shear is composed of a fixed shearing blade, a moving shearing blade, a shearing handle, and a saw, which are installed on the same center pin in turn. The fixed shearing blade is composed of an integrated shovel and hook knife (outer shovel and inner hook). The moving shearing blade is connected in parallel with a ratchet, and cooperates with the fixed shearing blade to form a scissors.

The scissor handle is a suit body with a built-in movable adjustment mechanism, which can telescope in the air (lengthen or shorten the scissor handle), and the lever principle is used to scientifically determine the length of the power arm. The pruning handle is equipped with a pawl, which can turn the ratchet to rotate the pruning operation. The saw handle is equipped with a positioning buckle, which cooperates with the buckle door provided on the fixed shear blade. It can be locked and opened and closed in the air, and can be used with the pull rope to saw thick branches.

Scope of application: high-altitude garden pruning, fruit tree pruning, etc.

2. What are the uses of garden shears

1. Adjust the reasonable distribution of branches and leaves. That is, on the basis of shaping, the density, distribution direction and leaf area coefficient of branches and leaves of each part of the crown are adjusted to maximize the effective photosynthetic area of ??the crown.

2. Regulate growth and results. It can make the vegetative growth normal but not overly exuberant; it can produce flowers and fruits in an appropriate amount without weakening the tree vigor; at the same time, it can prevent the fruit trees from aging prematurely and renew and rejuvenate them in time.

3. Adjust the composition ratio of branches. Different tree species and tree ages require corresponding and appropriate proportions of branches, so that the movement, distribution, consumption and accumulation of nutrients in the tree during the annual growth cycle can be coordinated according to the normal growth and reproduction rhythm.

4. Pruning can also balance the growth potential between groups of plants and between main branches on a plant, thereby achieving balanced yield and easy management. In addition, pruning is also a means to coordinate the growth of the above-ground parts and the root system.
