1 pruning shears
Pruning flowers and trees with pruning shears is the main method to coordinate the rational growth of all parts of flowers and trees, maintain tree shape, promote flowering and fruiting, and prevent pests and diseases. More importantly, the incision is neat and not easy to damage flowers and trees.
It can be used for pruning all year round. For example, in the spring and summer growing season of trees, diseased branches, dead branches, weak branches and long branches can be cut off or shortened at any time. Before pruning, we should distinguish the growth direction of the branches and buds and make the right choice. There are usually bud eyes on the left and right sides of branches. If you want the branch to develop to the right, cut it short in front of the bud on the right side of the branch, and the length is ideal. Because the buds of trees have the law of top growth advantage, the buds at the top of branches grow fastest, and the new branches at the right bud eye grow to the right, and vice versa.
Scope of application: pruning of various small plants, shrubs and fruit trees, etc.
2. Gardening scissors
The cutting edge of gardening shears (branch shears) is round, which is used to trim shrubs. When pruning, the force used makes the upper cutting edge gradually enter the branch, and the lower opening plays the role of supporting the branch so that the branch will not break. In addition, scissors are very labor-saving to use. Generally, scissors have telescopic design, and the arm can be adjusted to suit different users!
Yes, but before you start, you should make sure that the scissors are 90 perpendicular to the plant (to prevent the embarrassment of untidy cutting), and try to keep the end of the blade close to the plant (also to save labor). If you are careful, you will find that the blade and handle of ordinary scissors are not in the same plane, which is also a labor-saving design for the lever principle. To sum up, it is three words: fast, accurate and ruthless!
Scope of application: shrub pruning, lawn pruning, etc.
3, thick branch scissors
Coarse branch scissors are also called branch scissors, strong scissors and Hercules scissors. Garden cutting tools, which can cut branches 0-4 cm thick, are similar to vises and are essential items for woody trees. The cutter head has a straight mouth shape, a meniscus shape or a hay knife edge shape and a hand scissors shape. Although the quality of rough branch shears is generally reliable, dry and soft wood is not suitable for cutting.
Rough branch shears have two different blades, one is sharp for cutting and the other is blunt for squeezing, so the use method is similar to pruning shears (pay attention to the cutting order of reserved parts and removed parts), but the length of the arm should be adjusted according to the thickness of branches and their own strength when operating (most rough branch shears are telescopic now).
Scope of application: fruit tree pruning and shrub pruning.
4, high-altitude scissors
The aerial shear consists of a fixed blade, a movable blade, a shear handle and a saw, which are installed on the same central pin shaft in turn. The fixed cutting edge consists of an integrated shovel and a hook knife (external shovel and internal hook). The movable cutting edge is connected in parallel with the ratchet wheel, and the ratchet wheel is matched with the fixed cutting edge to form scissors.
The scissors handle is a suit with a movable adjustment mechanism, which can be extended or shortened in the air. Using lever principle to scientifically determine the length of power arm. A pawl is arranged on the handle of the scissors, and the pawl can toggle the ratchet wheel to rotate the pruning operation. The handle of the saw is provided with a locating buckle, which can be locked and opened in the air in cooperation with the buckle door on the fixed shear piece, and can be used for sawing thick branches in cooperation with the pull rope.
Scope of application: high-altitude garden pruning, fruit tree pruning, etc.
Second, what is the purpose of gardening scissors?
1, adjust the reasonable distribution of branches and leaves. That is, on the basis of reshaping, the density, distribution direction and leaf area coefficient of each part of the crown are adjusted to maximize the effective photosynthetic area of the crown.
2. Adjust growth and results. Make nutrition grow normally but not too much; Moderate flowering and fruiting without weakening the tree; At the same time, it can prevent fruit trees from aging ahead of time and renew and rejuvenate in time.
3. Adjust the proportion of branches. Different tree species and tree ages need to have corresponding and appropriate branch proportions, so that the operation, distribution, consumption and accumulation of nutrients in a year's growth cycle can be coordinated according to the normal growth and reproduction rhythm.
4. Pruning can also balance the growth potential between plants in the population and between the main branches of plants, thus achieving balanced yield and easy management. In addition, pruning is also a means to coordinate the growth of shoot and root system.
