Luohansong modeling technology, also known as Luohansong, Tushan pine, Sandy pine, etc. The purpose of modeling is to use superb artistic expression techniques to excavate the artistic realm from ordinary trees and enhance the ornamental value to the extreme. Commonly used modelling technique are cutting, binding, pressing, binding and hanging. Let's take a look at Luo Hansong's modeling technology!

Luohansong modeling technology 1 1 scissors

Taking advantage of the pruning resistance and small leaf shape of arhat pine, it can be made into various shapes, such as spheres, cones, multi-layer spheres, etc., just by pruning according to the pre-designed graphics. If the pruning design is a three-layer sphere, the total height is 2 meters, the lower layer is about 50 centimeters high, the middle layer is about 40 centimeters high, and the upper layer is 30 centimeters high. The height between the first layer and the second layer of the trunk is 45 cm, and the branches with a height of 35 cm between the second layer and the third layer need to be trimmed, and then three balls need to be trimmed.

2. tie

Strong bamboo poles and tough hemp ropes can be used for modeling. Tie the bamboo stick and the branch tightly with hemp rope, and then fix one end of the bamboo stick on the trunk. By adjusting the direction of the bamboo stick, the branch will grow in a specific direction according to the stylist's wishes, so as to achieve the purpose of modeling.

3. Pressure

Pressing modeling is mainly through bending and tilting the trunk, so that the tree presents a completely different artistic beauty on the inclined plane from the vertical plane. Because the branches of Podocarpus are like human arms, the hemispherical leaves produced by the cluster are planted at the top of the branches like the palms of human hands, and the curved tree body is like a greeter bending his arms to greet guests, which is very vivid.

Lohan pine pruning method

1, refinement

Loach thinning means cutting off the branches from the base. Through thinning, the stump can be ventilated and transparent, and the nutrition supply is concentrated and it grows vigorously. Early thinning of young trees is beneficial to normal development and growth. Thinning can make the left molding branches get enough nutrition and accelerate the forming. The molded stump bonsai can balance nutrition through thinning, making it old and enduring.

When thinning, cut off the branches of pests and diseases and burn them immediately to prevent the spread of pests and diseases, and cut off the branches that are unsightly in time.

2. Short scissors

The short cutting of Podocarpus is to cut off the long branches, stimulate the axillary buds under the incision to germinate and form strong side branches, so as to promote their branching and facilitate modeling. After thinning the redundant branches in plastic surgery, the remaining plastic branches should be cut short to make them sprout 2 ~ 3 times a year. Once sprouted and chopped, the number of branches of modeling branches will increase rapidly, and the order of each branch will be shortened without lengthening the branches.

3. Shrinkage and shearing

Pruning of arhat branches refers to pruning of perennial branches, which is a powerful measure to shrink big trees and an important means to promote the germination of new branches and restore tree vigor. For pile-type landscape plants with good stump posture, but large crown and long main branches, it is impossible to meet the requirements of pile-type landscape modeling only by cutting short annual branches. By shrinking and cutting, the big tree can be made smaller, which is beneficial to the landscape modeling of piles.

For some tree species with strong germination ability, the cutting amount can be larger, that is, the branches and leaves can be trimmed, and only the skeleton of the stump can be retained to stimulate the germination of new branches under cutting.

Podocarpus modeling technology 2 Podocarpus cultivation method

1, soil

Podocarpus culture needs slightly acidic culture soil which is rich in humus, loose and fertile, and well drained. In alkaline soil, leaves turn yellow, grow slowly and have a long life span, which can reach hundreds or even thousands of years.

water

Podocarpus is not a Pinaceae plant and is not drought-tolerant. On the contrary, Podocarpus is moisture-tolerant, and it needs to be watered frequently during the growing period, but it is not suitable for waterlogging. When it is sunny in summer in Shunde, you should pay attention to watering frequently. Generally, it should be watered once in the morning and once at night. In addition, you should always spray water on the leaves to make them bright green and grow well. There is usually more rain in summer, and Podocarpus is not tolerant of waterlogging, so attention should be paid to prevent long-term water accumulation.

3. sunshine

Podocarpus is a neutral negative tree species, which can accept strong light and grow in a cool environment. Although the temperature is high and the sunshine is strong in summer, it is not necessary to shade the Podocarpus in summer, because it is beneficial to keep the tree shape under the condition of high temperature and strong light. However, the seedlings of Podocarpus are young and tender, so it is not suitable for long-term strong light irradiation. It is recommended to keep them in the shade.

4. Temperature

Podocarpus is suitable for potted plants in northern China. When the outdoor temperature is stable at around 10℃, he will leave the room, put it in the lee of the outdoor sun for maintenance, and move to the semi-shade after summer. When the temperature does not drop to 5 degrees Celsius in winter, it is necessary to enter the room. After entering the room, control watering, and you can safely overwinter without freezing.

5, fertilization

Luo Hansong likes to fertilize, so he should apply it thinly and frequently. The fertilizer is mainly nitrogen fertilizer, and appropriate amount of black alum can be added to make alum fertilizer water. Fertilization can be applied every 1 ~ 2 months during the growth period, and fertilization can be combined with watering (the ratio of water to fertilizer is 9: 1).

6. Pests

Podocarpus is mainly harmful to leaf spot and anthracnose, and it is sprayed with 500 times of 50% thiophanate-methyl wettable powder. Insects include scale insects, red spiders and giant salamander, and 40% omethoate EC 1500 times can be sprayed.

Podocarpus modeling technology 3 Podocarpus bonsai pruning

1. One of modelling technique's "cutting" of Podocarpus bonsai: By using the characteristics of Podocarpus's pruning resistance and small leaf shape, it can be made into various shapes, such as round, conical, multi-layer spherical, etc., and only needs to be trimmed according to the pre-designed graphics. For example, when pruning a three-layer sphere, first choose seedlings with obvious trunk and good upright shape.

If the pruning design is a three-layer sphere, the total height is 2 meters, the lower layer is about 50 cm, the middle layer is about 40 cm and the top layer is 30 cm. The height between the first layer and the second layer of the trunk is 45 cm, and the branches with a height of 35 cm between the second layer and the third layer need to be trimmed, and then three balls need to be trimmed. The above three kinds of balls should be longer and bigger, which is more ornamental in proportion. Generally, it is advisable to prune new branches when they are 20 ~ 30 cm away, and prune them several times to make each layer round and dense.

"Tie" with bamboo sticks and hemp rope

2. modelling technique's second "binding" of Luohansong bonsai: The binding method can choose strong bamboo sticks and tough hemp rope, tightly bind the bamboo sticks and branches with hemp rope, and then fix one end of the bamboo sticks on the trunk to make the branches grow in a specific direction according to the stylist's wishes, so as to achieve the purpose of modeling.

It should be noted that the tying method is suitable for the younger Podocarpus, while the older Podocarpus is difficult to tie because of its thick branches, and the effect is not good.

The stake supports the inclined side of Luo Hansong.

3. The third "pressing" of modelling technique in Luohansong bonsai: The pressing molding mainly makes the tree body present a completely different artistic beauty on the inclined plane through the bending and inclination of the trunk. Because the branches of Podocarpus are like human arms, the hemispherical leaves produced by the cluster are planted at the top of the branches like the palms of human hands, and the curved tree body is like a greeter bending his arms to greet guests, which is very vivid.

It should be noted that after the tree body is bent, the inclined end must be supported by a wooden stake to prevent the tree body from falling down due to excessive inclination, and the contact surface between the wooden stake and the tree body should be padded with straw with moderate thickness to avoid hurting the tree body.

Copper-iron combined forming method

4. modelling technique's fourth "Tie" of Luohansong bonsai: Tie can be made of iron wire, copper wire and plastic tape. In the process of operation, the wire can be selected according to the thickness of the branches, and it is difficult to model the thicker branches. The iron wire can be tied against the branches with plastic tape, and then the tied branches can be bent by hand according to people's will, and the iron wire can be untied in about half a year or a year, when the branches are one year long.

Difficult branches can be operated. Cut a small hole with a knife at the point to be bent, so that the branches can bend down. After bending, the wound must be wrapped with fresh moss or sterile soil to make the wound heal.
