Deciduous trees, 10-20m high. The length of bipinnately compound leaves is 20-60 cm, with pinnae 15-20 pairs, lobules 5- 10 cm and lobules 25-28 pairs. Leaflets are compact, small, rectangular, 4-8 mm long, with filiform hairs on both sides and obtuse tips. Umbrella racemes are terminal and axillary; The flower is large, with a diameter of 7-10 cm; Corolla bright red to orange red with yellow spots. Summer is flowering.

The flowers are red, green and green, and the trees are full of fire, magnificent and full of crowns, like butterflies flying on them.

DBH can reach1m; The bark is rough and grayish brown; This tree is a wide umbrella with many branches; Branchlets are usually short tomentose and have obvious lenticels. When leaves fall in winter, countless leaflets fall like snowflakes. Sexual love likes the environment of high temperature for many days and must flourish in the sunshine prescription.
The leaves are bipinnately compound leaves, with opposite pinna, 15-30 pairs, and each pinna has 20-40 pairs of leaflets. Leaflets are oblong, with oblique base, entire leaf margin and blunt tip. The leaves are as thin as paper, smooth, thin and blue-green, and the veins are only obvious in the middle ribs.

Like many leguminous plants, the roots of Platanus acerifolia have rhizobia. In order to adapt to the rainy climate, the trunk has roots at the base. Indus adapts to tropical climate, bears drought and can grow in salty environment.
Growth habit
Platanus acerifolia began to blossom after 6-8 years of planting, and it likes high temperature for many days, so it must flourish in sunny conditions. Therefore, it grows rapidly in the southern tropics, generally 1.5-2m high, 3-4m in two years, with high trees and large crowns. Phoenix likes light and shallow roots, and the average suitable temperature is 20-24℃. Every year, the buds germinate at the beginning of February, and the growth peaks from April to July. In late July, the growth decreased due to high temperature, and in the middle and late August, the temperature dropped to accelerate the growth. After 10, the growth slowed down, and 65438+2- 1 month shed leaves.
I like sunshine, high temperature and humid climate, and the cultivation land can adapt to full sunshine or half sunshine. The soil quality must be fertile sandy loam rich in organic matter, well drained, not resistant to drought, barren, cold, wind and air pollution. Landscape trees, shade trees and street trees. Phoenix wood is suitable for planting in sandy soil with sufficient sunshine, shade and good drainage. The flowering period is from June to July. Breeding, seed breeding, must first soak in 90 hot water for 5~ 10 minutes, and the germination rate is high.
Planting method: Suitable for single planting.
geographical distribution
China, Taiwan Province, Hainan, Fujian, Guangdong, Guangxi, Yunnan and other provinces have introduced cultivation. Origin Madagascar and other tropical places in the world. In the United States, plane trees only grow in Florida, Rio Grande Valley in southern Texas, desert areas in Arizona and California, Hawaii, Puerto Rico, the United States Virgin Islands and Guam. Sycamore trees are also widely planted in the Caribbean.
Utilization of wood: its wood is dense, light and elastic, and can be used as raw materials for furniture, plates and paper making.
