Buttonwood tree has a round crown, beautiful trunk shape, smooth green bark, large and beautiful leaves and shade. It is a garden ornamental tree with a long planting history.
Often planted alone or in clumps on lawns, courtyards, hillsides, lakes, etc. , especially with palm and bamboo. "Planting tung in front of the house, then planting bamboo" is a traditional planting method in the south of the Yangtze River, and can also be used as street trees and green trees in the factory.
Indus is a deciduous tree, about 20 meters high.
The bark is turquoise and smooth. Leaves heart-shaped, 30 cm in diameter, palmately 3-5-lobed, lobes triangular, entire, glabrous or slightly pubescent on both surfaces, stems with 7 veins, petioles nearly as long as leaves. Panicle terminal, 20 ~ 50 cm long, yellow-green flowers, linear sepals, reflexed ovary, round hair, flowering in June.
Follicle membrane, peel split into leaves, spoon-shaped, obvious reticulate veins, short or almost hairless outer cover. The fruiting period is 10 ~ 1 1 month.
Platanus acerifolia likes light, bears drought, has a warm and humid climate, and has poor cold tolerance.
I like fertile, deep and well-drained calcareous soil. I can grow on acidic and neutral soil and avoid water and saline-alkali soil. It has strong resistance to all kinds of toxic gases. Platanus acerifolia is a tree species with late germination and early defoliation. Generally, it germinates in mid-April and leaves in late 10, with an annual leaf age of about 225 days. Strong sense of dryness and layering, straight trunk and round crown. Fast growth, weak germination and long life.
Platanus acerifolia is a single-axis branch and is not resistant to pruning. The shaping method should be determined according to the growth potential and the needs of green space application, and can not be forced. It can be cut into a central trunk, but because the main branches are developed and there are few side branches, the central trunk often looks too high and has a poor shape, so it is usually not reshaped, and only the middle trunk is cut above the reshaping belt (2.5 ~ 3 meters) to form multiple trunks.
The branches of Platanus acerifolia often grow in a wheel shape, but there are often no branches between the upper and lower wheels, and there is a big gap. If we don't pay attention to this phenomenon, it will lead to the result of "pinching the neck".
No matter which plastic method is adopted, it is difficult to select and retain skeleton branches. Generally, some redundant branches in the same wheel are thinned, so that the branches left in the upper and lower wheels are balanced with each other to form a skeleton.
Indus has few miscellaneous branches, so it is generally only necessary to cut off a small number of redundant branches and dead ears when maintaining and pruning. Setup, maintenance and pruning should be carried out in winter.
