Basic knowledge of bonsai modeling: bonsai root modeling has knowledge and skill

One is to introduce the root.

When young trees are modeled, the main roots are cut off to promote the occurrence of lateral roots and extend horizontally to adapt to cultivation in shallow pots. If the larger tree, the root system is thicker, the root system can be fixed with wire, the shape is determined according to the shape of the basin, planted in a shallow basin. The root system can also be expanded horizontally, laid on a long plank, laid and fixed, and then planted in the soil together with the plank, so that the root system can be extended horizontally. The root system cultivated by this method can be suitable for planting people in a shallow basin only 1cm deep. Shanghai-style bonsai also uses this method.

The second is attached stone.

Stone attachment is the form of attaching the root system of a tree to the gap of the stone, or piercing the root system into the cave of the stone, forming a form in which the tree holds the stone and passes through the stone, which is called "stone attachment". When modeling, choose good plant materials and stone, plant materials should be well-developed lateral roots, slender. Stone should have a good shape with a certain momentum, good texture and multi-crevice caves. The root system of the tree is fixed in the gap or buried in the soil through the cave, and then the method of lifting the root is adopted to gradually expose the root system of the stone-attached part to the soil surface together with the stone. Plant into the appropriate pot to form a stone-attached bonsai.

The third is to inject air and take root.

Banyan trees and other trees that are prone to aerial rooting can be artificially induced by aerial rooting. the method is to tie a circle with wire in the branch where the aerial root is to occur, and cut off the channel for the plant to transport nutrients downward. To accumulate nutrients here. Then tie a strip of gauze cloth outside the metal ring and hang it down to the basin surface, and then put a bowl of water on the basin surface, soak one end of the sand cloth into the water, and the water seeps up to the metal circle through the sand face, creating an environment with high humidity, causing drooping gas to take root there. Also pay attention to the metal ring before falling into the cortex, should be cut off in time to avoid falling into the cortex, affecting the growth and ornamental of trees.

Fourth, Rugen.

Lugen is also called Tigen, that is, the upper part of the root system is raised to the soil surface, its purpose is to show its old and simple, and the other is to make part of the root hanging claws to reveal the beauty of its posture. The methods are as follows:

The above method: also known as the basin change method, this method is combined with the basin change, the root system is planted a little bit upward year by year, and then wash away part of the soil with water, gradually making the upper root system exposed to the soil surface. When necessary, the exposed roots should be treated according to the requirements of the picture. If the root system is too dense or redundant, it should be deleted, or the distribution of coarse root should be adjusted appropriately.

Sand cultivation method: the trees are planted in a deeper basin, the lower part is filled with fertile soil, the upper part is filled with river sand, the absorbing root system of the plant is introduced into the lower part, and then the upper part of the river sand is removed year by year, exposing part of the sturdy main and lateral root system, and then moving into the ordinary basin, the upper root is exposed. Tidy up the roots as above.

Addition method: this method is suitable for the height of the flowerpot is not enough, in the upper four sides of the flowerpot around the tiles or other materials, such as thin wood, plastic sheet, in order to improve the height of the flowerpot. When planting trees, fill the upper part of the river sand with soil or lower soil. When the tree absorbs the root system and extends to the bottom of the human body, then gradually remove the upper soil or river sand, remove tiles and other things to expose the upper root system. Shanghai bonsai is created in the same way.
