Pruning method of arhat pine 1 Refining method:
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. Generally, one of the two parallel branches that are close to each other should be cut off, one overlapping branch and one opposite branch should be cut off, only one whorled branch should be kept, and all the others should be cut off, and the long branches, upright branches, drooping branches and reverse branches on the main branch should be cut off. Branches and cross branches should be cut off one by one. The sprouting branches of tree species with strong germination ability should be cut off as soon as possible, in addition to leaving a branch in the missing part for slowly inducing and replenishing branches, so as not to consume nutrients and affect the tree potential.
Second, the shortcut method:
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, it is necessary to cut the remaining modeling branches short to promote them to 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. Therefore, short cutting is an effective measure to control the growth of stump bonsai and maintain its dwarfing, and it is also an important means for stump to have the shape and shape of a big tree as soon as possible.
Three. Shrinkage and shearing methods:
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 landscape plants with good stump posture, but large crown and long main branches, it is impossible to meet the requirements of pile landscape modeling only by thinning and pruning 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.
Luo's modelling technique Luo modeling is to transform the ordinary or even messy tree shape with various techniques and materials to achieve pleasing effects, thus enhancing Luo's added value. The purpose of Luo modeling is: modeling with trees, applying art with materials, and integrating the understanding and expression of art.
Modelling technique is diverse, and all of them are artistically processed according to the natural beauty of the seedlings, that is, they must be tailored for the trees to enhance the aesthetic feeling and make the shapes strong and distinct. Commonly used modelling technique are cutting, binding, pressing, binding and hanging.
Tie: You can use strong bamboo sticks and tough hemp rope for modeling. Tie the bamboo stick and the branches tightly with hemp rope, and then fix one end of the bamboo stick on the trunk, so that by adjusting the direction of the bamboo stick, the branches can grow in a specific direction according to the wishes of the stylist, thus achieving the purpose of modeling.
Pressing: Pressing modeling is mainly to bend and tilt 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.
Beam: Use bamboo pole, aluminum wire, hemp wire and other materials to create various complex shapes, including pavilions, animals and other shapes.
Hanging: Hanging bricks and other heavy objects makes the branches droop, creating an inclined plane effect.
Cutting: After the above-mentioned modelling technique shaping treatment, it needs to be trimmed without exception to make the shape more rounded and full. Pruning needs to combine season, water and fertilizer management, cut off too long branches, highlight branches and promote more branches. Only after repeated pruning can we achieve satisfactory results.
Propagation method of arhat pine. Sowing and propagation
Luohansong began to bear fruit at the age of 10, and the phenomenon of big and small years was not obvious. Seeds are best sown at harvest and cannot be stored until summer. When sowing, first soak the seeds for a few days, and then drill or sow as needed after the seeds fully absorb water. The sowing depth should be covered with seeds. After sowing, cover the grass with water and spray water once a day. If you sow in the open field, you need to cover the southwest with grass to protect you from wintering. Other areas need pot planting, and after planting, they will be moved into low-temperature greenhouses for the winter. The seedlings can be unearthed in 8- 10 days. Immediately after the excavation, cover the grass for shade. Don't be exposed to the sun. For potted plants, 1 year can remove terminal buds and promote multi-branch germination. Generally 1 year and a half to two-year-old seedlings can be planted in pots and begin to form curved branches. Planting plants, usually 3-4-year-old seedlings, should be taken out of the nursery with soil balls.
Second, cutting propagation.
1. softwood cutting: softwood cutting of Podocarpus Podocarpus refers to the cutting method of using semi-mature branches of the same year as cuttings in the growing season of seedlings, which is mainly suitable for evergreen and semi-evergreen woody flowers. Generally, the first half of the year is from mid-late May to early July, and the second half is from mid-late August to mid-late September. The seedlings planted in the first half of the year should pay attention to prevent high temperature burns and diseases, and the seedlings planted in the second half of the year should pay attention to heat preservation and antifreeze in the middle and late stages. The time to open the sunshade net is165438+1late October, and the time to open the sunshade net in dry years can be extended to 65438+late February.
2. Hard-branch cutting: Hard-branch cutting refers to the method of cutting thick branches that were completely lignified in the previous year during the dormant period from February to March in early spring. Attention should be paid to raising the soil temperature and controlling the air temperature in the shed in early spring. In a word, whether it is softwood cutting or hardwood cutting, we should do a good job of disinfection of cuttings and soil, and control the temperature, humidity and light of seedbed. In addition, in order to improve the survival rate of seedling cutting, some measures should be taken to promote rooting.
Third, layered communication.
The layering propagation of Podocarpus should be carried out before and after the spring solar term (that is, in early March). Select the branches that are slightly smaller than chopsticks near the ground with the dwarf Podocarpus ball, and obliquely cut half of the branches with a knife on the side near the ground at the base. Insert the prepared one-inch long bamboo pieces into the incision horizontally, insert a small wooden stick to help the branches, and gently bind them with plastic tape. Then cover the incision with loose soil, compact it gently, and cover it with hay to keep it moist. After 3 months, the branches can take root at the incision. After the autumnal equinox, cut it off from the base of branches with branch scissors and transplant it.
Conclusion: Through the above introduction, we know the pruning method and propagation method of Arhat pine. I hope this article is helpful to you!
