Bonsai with straight trunk trees should be made into towering "straight-wide" picture works with short branches. Tree species suitable for the straight-line project include Pinus thunbergii, Pinus bungeana, Pinus bungeana, Metasequoia glyptostroboides, Ginkgo biloba, elm and so on. Most of these materials were taken from forest farms, and some were dug from Shan Ye.
(2) The bent stem type bonsai tree requires the trunk to have a certain degree of bending change, but the bending should not be too much, and one or two bends are enough. Avoid too monotonous repetition, otherwise there will be traces of human creation. Qu Gui is alive, which lies in the change of the main line, combining rigidity with softness, combining rigidity with softness, smooth lines, euphemism and combining rigidity with softness.
The raw materials of Shanjian Ganqu are unpredictable, vigorous and natural, and very valuable, but there are also unsatisfactory line changes, so we should pay attention to the selection. When planting artificially cultivated dry songs, the trunk must be slightly inclined, so that the roots on the other side can be cultivated into thick roots, which are half exposed on the soil surface, and the joint between the roots and the trunk is smooth and harmonious in one go. This is the most important ornamental part of the bending dry tree bonsai, which must be highly valued. For the part above the base of the trunk, it can be truncated by cutting to let the trunk choose another development direction. In the future, the trunk can be trimmed and tied to meet the requirements of bonsai beauty.
Cypress is the most typical dry bonsai material. Other trees such as pine trees and some miscellaneous trees are also suitable for forming dry bonsai.
(3) The inclination of dry tree trunks is mostly caused by strong winds, landslides, landslides and other factors. Therefore, the morphological changes of trunk inclination are also very complicated, but one thing is that its trunk line is not a straight line, but various deformations of "S" shape. In nature, this posture of leaning trunk is reflected in tree bonsai, which we call oblique trunk type. The trunk of inclined stem bonsai materials must have various deformed "S" shapes. If the trunk leans to the right, there should be thick roots on the left, and the tip of the trunk turns up, just like the sloping bonsai material for many years. If the trunk is inclined and the trunk line is straight, it lacks charm and does not conform to the laws of nature Because there will be no strong wind every day, and the trees will continue to grow upwards.
The key point of making bonsai with inclined stem trees is how to make the tree lose its center of gravity and achieve balance. Its methods include: playing the role of thick roots in the opposite direction, playing the role of branches in the opposite direction and the fall of big branches inclined in the same direction, giving people a feeling of support.
In order to strengthen the inclination of potted trees and make the composition active, it is advisable to choose a round shallow basin, a square shallow basin or a semi-high round basin to let the inclined trunk or branch out of the basin.
Pine and cypress trees and some miscellaneous trees are suitable as materials for inclined dry bonsai.
(4) Cliff-like On the cliffs of nature, some common trees grow in various postures, which are thrilling but still lush. Trees with this posture are embodied in bonsai, which are collectively called cliff style.
Cliff type generally has semi-suspension type, full suspension type and upside down type.
Semi-suspended: the bonsai tree emerges from the basin as a whole, but the tree body is not lower than the basin surface. It may be that the trunk is out, or the trunk is short, and the first branch is thicker and longer, thus gaining momentum when facing the air.
Full suspension: the bonsai tree comes out of the pot as a whole, extending downward in a dumping way, with branches outside.
Inverted type: the bonsai tree is out of the pot as a whole, the bare trunk is upside down vertically and the branches are still outside.
The production of cliff bonsai focuses on the selection of materials, which requires that the base of the trunk of the material has a certain bending change so that the trunk or branches can span out or droop. Although cliff bonsai is popular, it must be considered according to the material conditions and follow the modeling principle of "adapting to the material".
Cliff bonsai used to be planted in flowerpots to compare the momentum of trees falling from a height. At present, plants are mostly planted in half-height square or round pots, and several high frames are used to create cliff momentum when arranging exhibitions. Its advantages are that it can improve the cultivation and management of trees that are not conducive to high-density management; In terms of viewing, the trinity of scenery, basin and shelf can be achieved, which is vividly displayed, thus making the picture transparent, harmonious and vivid.
(5) The double-stem and double-stem tree bonsai appears in the form of two trees combined together, which embodies the artistic beauty of modesty and coordination, proper density and combination of reality and reality between the two trees, thus showing the realm of both form and spirit and scene blending.
The following points must be paid attention to in the production of double-dried bonsai.
The choice of two trees must have primary and secondary points. The main tree is taller and the secondary tree is shorter.
The posture of the main tree is dominant, and the posture change of the trunk of the secondary tree is roughly similar or close to that of the main tree, forming a certain tacit understanding. If the posture changes of two tree trunks are completely different, it is difficult to produce harmonious beauty and should be avoided.
Planting two trees should have front and back, not parallel. Who comes first, depends on the specific situation. When planting, the trunk bases of two trees should be close, and the roots should be basically the same and cannot be separated. The included angle between the trunk extension directions of two trees should not be too large, and it is generally ideal within 45. If it is too big, the trunks of two trees may lose mutual echo and expectation.
The branch selection and adjustment of double trunk branches are complicated, so the two trees should be treated as a unified whole to achieve overall balance and stability, coordination between virtual and real, and orderly competition.
The lower branches of two trees should extend outward, and the thicker branches should be cut off between the two trunks to avoid the intersection of the thicker branches and the trunks. The branches between the two trunks should be filled with branches on the front and back sides to avoid going straight, which is the most natural.
In addition, the branches of the main tree should be higher, and the branches of the secondary tree can be slightly lower to avoid the influence of the main branch on the growth of the secondary tree.
Double stem planting can also be two different tree species, but the best combination is still a tree species.
Double trunk type is the combination of two trees, or can be combined with a double trunk type, collectively known as double trunk type. Because from the modeling point of view, their trunk processing and branch processing are the same. It is possible that a book with two jobs was originally integrated and was later split in two by external forces. The height, thickness, straightness and exposed changes of the two main branches all meet the performance requirements of bonsai art, and the relics are natural and slightly decadent. Divine branches are indispensable, but they are artificial. Two waterline widths, both on the outside of the trunk, are ideal. The crown is closely combined by two crowns, and its potential is unified with the two stems. The whole tree is dynamic, compact, stable, calm, unified and harmonious.
