Alias: maple tree

Scientific name: Fengxiang

Family and Genus: Liquidambar of Chimonanthaceae.

Distribution: China Yangtze River Basin and its south, Sichuan and Guizhou in the west, Guangdong in the south and Taiwan Province Province in the east; It is also distributed in Japan. Vertical distribution is generally in hills and plains below1000-1500m.

Morphological characteristics: trees, up to 40 meters, DBH 1.5 meters; ; The crown is broadly ovate or slightly flattened. The bark is gray, shallowly split longitudinally, and irregularly deeply split when it is old. Leaves are usually palmately 3-lobed (bud branches and leaves are usually 5-7-lobed, 6- 12cm long, heart-shaped or truncated at the base, with sharp lobes and serrated edges; Young leaves are hairy and gradually fall off. The result sequence is large, with a diameter of 3-4cm and persistent style1.5 cm; . Sepals spiny persistent. Flowering in March-April; /kloc-The fruit ripens in October.

Ecological habits: like light, young trees are slightly tolerant to shade, like warm and humid climate, drought-tolerant and barren soil, and not tolerant to waterlogging. It's very humid. It grows well in rich crimson and yellow loam. Deep root, long taproot, strong wind resistance, not resistant to transplantation and pruning.

Ornamental characteristics and garden use: Liquidambar formosana is a famous autumn leaf tree species in southern China, with a straight Gao Qian, a broad crown, magnificent momentum and beautiful leaves in late autumn. It is very suitable for creating scenic forests in the hilly areas of southern China. It can also be planted as a shade tree in gardens, alone or in clumps on the grass, or mixed with other trees and planted on hillsides and Chi Pan. If you plant evergreen trees, they will be red and green in autumn, which will be especially beautiful. Lu You has a poem "Counting trees reflects cypress". Liquidambar formosana has strong fire resistance and the ability to resist toxic gases, so it can be used for greening in factories and mining areas. However, due to its intolerance to pruning and difficulty in transplanting big trees, it is generally not suitable for street trees.

red maple

Hongfeng, a variety of chicken claw machinery, is a very beautiful foliage plant. Its leaves are beautiful, palmately 5-7-lobed, with persistent red color, orderly branches, distinct layers and light and natural tree posture, so it is widely cultivated.

Hongfeng likes sunshine, is afraid of scorching sun and western sun, likes warm and humid climate, is cold-resistant and slightly early-tolerant; Not tolerant of waterlogging, suitable for fertile, loose and well-drained soil.

Red maple is a precious foliage tree species, so it is often seen in potted plants. When potted, 2 parts of garden soil, 2 parts of humus soil and sand 1 part can be used to prepare culture soil. Red maple should be transplanted in February-March, and leaves should be picked and soil balls should be brought when transplanting in the growing period. Daily watering should be between dry and wet, to prevent it from being too dry or wet, and to prevent basin waterlogging when it rains in summer. Fertilization can be applied as appropriate during the growth period. Potted plants are generally fertilized 2-3 times a year. Too much fertilization, too many branches and fast growth, easily lead to imbalance in the proportion of trees and pots. Full sunshine is acceptable in spring and autumn, and it should be moved to a semi-shady place after summer to avoid direct sunlight at noon. When it is dry and hot, it should be properly sprayed with water to cool and humidify. Red maple leaves will be scorched or folded in high temperature, dryness, scorching sun, dry soil, stagnant water and air pollution.

type

The sowing variation of Acer truncatum is great, and it is mainly propagated by grafting and cutting. Grafting propagation should use 2-4 year-old Acer truncatum seedlings as rootstock, cutting should be carried out in March-April, and the height of rootstock can be determined according to needs; Docking in rainy season from May to June, and cutting after defoliation in autumn. This method is only used for a few rare varieties. Bud grafting is the most common application, and the best time is from late May to late June and from late August to late September after autumn. Early summer is the peak period of branch growth. The full buds on the sunny short branches of Hongfeng were used as grafting buds, and the petiole was 65438±0cm long. The temperature is getting higher and higher after grafting. Although the grafting is wrapped with plastic tape, the buds and petioles are still exposed. In addition, red maple has thin cortex and small grafted buds. Therefore, it is necessary to spray moisturizing regularly after pressing to improve the survival rate. This is basically the case for budding after autumn. After a week of grafting, if the petiole falls off as soon as it touches, it means it has survived, otherwise it should be patched.

Red maple can also be propagated by cutting. It is best to use this method when making small bonsai or potted plants. Cuttings are usually carried out in the rainy season from June to July. The headmaster, who was about 20 cm long, was selected as the cutting, quickly dipped in 1000ppm NAA powder and inserted into the matrix of mangshi or perlite and pond mud. Pay attention to shading in the future; Spray water for moisturizing, and it can take root after about 1 month. 2-year-old branches can also take root with high survival rate if there is full light spraying condition. Shading should be done after transplantation, and after half a month, sunlight can be gradually accepted, and water and fertilizer management should be strengthened.

How to make Hongfeng reproduce the red leaves during the National Day holiday?

Most varieties of Hongfeng are red in the new leaf stage, gradually turn green in summer, and then turn red after frost. In order to make the red maple turn red before and after the National Day, we can use the method of picking leaves to promote red, forcing new leaves to sprout. The specific method is to remove all the leaves and petioles from the plants in mid-August. Put it in a sunny place, follow the manure 1-2 times, water it 1 time every day, keep the basin soil moist, and spray water on the branches appropriately. After about half a month, axillary buds will sprout one after another and open into small red leaves. In late September, the whole leaves are ripe and the whole tree is red, just in time for the National Day flower viewing.
