Generally speaking, the branches of bonsai trees mostly grow vertically. In the process of making bonsai, in order to make bonsai have certain ornamental value, we often hope that it can adjust the direction, bending and twisting of branches according to our ideas. Make it achieve better results in flower viewing, leaf viewing and viewing. If you want to do this, you need manual processing and master some techniques that can stabilize the branches. Let them grow into what we want in the future. After years of exploration by predecessors, there are indeed many empirical means. Son, I summed up a few points.
1, coil forming method
In the production of bonsai, a common method. It is divided into two methods: steel wire winding and brown wire winding, which are mainly used to bend the trunk during modeling, and both have their own advantages and disadvantages. For the bending of the trunk, we must first understand its habits, and on this basis, in the appropriate season, according to the situation of the tree, take reasonable methods to bend it reasonably. Protect the bark and branches of plants from damage to the greatest extent.
(1) brown filament winding method
In modeling, the contact surface between brown silk and trunk is relatively small, which is not easy to cause damage to bark and is beneficial to tree growth. When bending branches, according to the position and modeling requirements of branches, choose reasonable knotting points and positions that need to be knotted. At the beginning, the flat point can be selected in the rough parts of branches and branches that do not affect the shape, so as to prevent the rope from sliding and affecting the effect. If the branches are too smooth, you can wrap a layer of cloth first. The bending degree should be reasonably judged according to the softness and thickness of the branches.
(2) Winding method
Copper wire, iron wire and lead wire are often used in the modeling process. The thicker the branches, the thicker the lines, so that the shaping effect can be better. Pay attention to your own skills during the operation to avoid hurting the bark. If you are not confident enough, you can wrap the wire with cloth first, which can play a certain protective role. In the later growth process, it is necessary to observe the situation frequently. Once the wires are found embedded in the branches, they need to be pulled out in time. When winding, follow the principle of from inside to outside, from bottom to top, first main and then secondary, so that the wire and the branch are wound upward at a tangent angle of 45 degrees. When reaching the end of modeling, the tail of the wire should be attached to the bark and cannot be tilted.
2. Branch storage and trunk cutting methods
In this method, when the branches grow to the required thickness for modeling, they are pruned in large quantities. At the same time, branches with appropriate positions and angles are selected and left. When they grow to the appropriate thickness, they are pruned again, leaving new side branches. This cycle is repeated, and this method is applied to each section of the trunk, so that plants are gradually formed. After years of pruning, the proportion of branches has become symmetrical and tortuous. The bonsai cultivated by the method of saving branches and cutting dry is just right in density and full of artistic conception. Gradually become the form you want.
3. Traction method
This method is mainly used in various forms, such as pulling. Although it is possible to tie the branches of the metal wire and then drag them to achieve the purpose of bending or adjusting the direction, this method has only appeared in recent years. In the past, the tools used by masters were ropes, but now people use tractors instead, which are relatively simple and easy to operate. Just gently pull the handle to shrink the traction rope, which plays a role in tightening the traction. This operation can make the branches bend slowly, without causing great damage to the branches or affecting the healthy growth of plants.
