How is the American Modified Red Maple Acer officinalis cultivated?

1.Spacing. In order to get enough light, proper thinning should be done.

When pruning, the main thing is to prune the old branches, do not cut the evergreen green leaves, and you can cut off the dead and too long vines, and prune the branches that grow horizontally in a staggered manner, and the pruning must be neat and consistent, so that the shape will be beautiful.

Some yellowish and withered leaves should be pruned at a certain stage of growth, so as to ensure that the other branches grow very densely and avoid some disasters.

First of all, we should cut off some useless branches and leaves, and we should also prune them out of shape, and at the same time, we should give more water and apply more fertilizer, so that the tree can grow stronger, and try to cut off some branches and leaves with dead branches or few leaves.

American autumn red maple is cold tolerant, -35 resistant, and adapts to neutral and slightly acidic or slightly alkaline soils. The growth rate is relatively fast, with an average annual growth of 80cm-120cm (depending on the soil and water fertility). Pure Autumn Flame is a hybrid that does not bloom and does not set seeds.

Other American red maples bloom in spring and have red flower spikes with winged fruits and light red seeds. The leaves are palm-shaped, about 5-10cm long, the young buds are light red in spring, bright red in summer and autumn, and the hanging period is long and the leaves fall late. The trunk is straight and dark brown, and the material is hard and well-grained.

1.U.S. Modified Red Maple (Fall Flame) Pruning Season: Light pruning can be done year-round, heavy pruning should be done in early spring before bud germination.

2.After the planting of the improved red maple (autumn flame) in the United States, when the improved red maple (autumn flame late search) grew to the fixed pole height, topping was carried out to promote the secondary branching, and then 3 5 robust branches could be left as the main branch, and 1 2 branches with different angles and balanced growth were selected as side branches on the main branch. When pruning every year, the upper branch with a large angle should be selected as an extension branch and appropriately shortened.

This kind of tree-shaped beam has good permeability and can be viewed in three dimensions. In addition, diseased branches, insect branches, weak branches, overlapping branches, long branches, and cross branches can be cut off, so that the pruning makes the crown of the American improved red maple (autumn flame) more perfect and beautiful. "

Place of origin: The United States Huacai Sannong is brought in by Jiangxi Sannong.

Family: Acer genus.

Acclimatization temperature: 42° to minus 30°C

Scope of application: parks, courtyards, municipal plants, streets, sightseeing parks, scenic spots, autumn red maple ornamental gardens, special gardens, etc.

Characteristics: The main color of autumn leaves is slightly dark red, the red leaves are stable, and the flowers bloom in spring with red flowers. The fastest growth, 1 year planting seedlings can reach more than 2 meters, strong resistance, autumn flame is very disease-resistant, not bothered by car exhaust, with strong frost damage and wind advantages, because of its autumn quil limbs with seasonal spike color and dazzling reeds, long duration, is one of the ideal rare tree species for beautification and greening of urban gardens introduced in recent years.

Planting Management Techniques for American Red Maple:

1.Spacing. In order to get enough light, proper thinning should be done.

2.。Land selection and colonization. Land with an acidic or neutral pH and good drainage should be chosen. There is little relationship between soil type and can range from sandy to sticky.

3.Irrigate. American red maple prefers moist soil, especially during the growing season, which requires a lot of water and requires frequent irrigation. Flood irrigation is also acceptable, but flood irrigation should not be too long, not overnight, and the time of each flood irrigation should be controlled at 30 minutes to one hour.

4.Fertilize. The optimal pH range for red maple is. The amount of phosphorus and potassium fertilizer required is moderate to high, and it is advisable to apply it early and fertilize it before ploughing. Acer alberta and other maple grow rapidly in high nitrogen.

5.Disease. Seedlings are susceptible to blight and cataplexy.

6.Pest. Aphids, pests (spider mites, tassel mites), maple scales, stinging moths, caterpillars, and leafhoppers are also frequent pests in red maple, which can generally be controlled with 400 times the solution of Lesben, imidacloprid, and cypermethrin.

7.Weeding. Red maple is sensitive to many herbicides, should not be used blindly, must do a small-scale test first, in order to prevent the occurrence of pesticide damage in a large area.

8.Trim. The red maple does not require much pruning work, and it is necessary to keep the trunk strong and the crown well-proportioned. If the main stem is damaged, it is necessary to extinguish the shoots when double shoots are produced. In addition, when the roots germinate new shoots, they also need to be extinguished. Other times you don't need to prune.

The growth rate of American red maple is closely related to factors such as temperature and light, soil properties, water and fertilizer management, pest and disease control, and weed control. Its growth potential is huge, and if it can be controlled to the best state, the growth rate of red maple can reach the usual growth rate.

Two, triple. For example, if the dry diameter is 10 cm, it can be successfully cultivated in 3-4 years.
