Differences between French Indus, Paulownia and Indus

Platanus acerifolia is a deciduous tree belonging to Platanus, which is unrelated to Paulownia (Euphorbiaceae), Scrophulariaceae and Platanus (Platanus).

The buttonwood tree is tall and burly, with a knotless trunk, soaring upwards, holding a huge green umbrella like emerald high, with high momentum. The bark is smooth and green with dense leaves. From branch to branch, it looks elegant and clean. No wonder people also call it "Qingtong". The two poems, "A verdant tree stands tall in Chiba, Lv Yun Municipal Committee", vividly depict the scenery of the green trunk of Chinese parasol trees and the swaying shadows of Chinese parasol flowers.

Platanus acerifolia is a beautiful ornamental plant, dotted in gardens and houses, and also planted as a street tree. The leaves are palmately shaped and split like flowers. Summer flowers, monoecious, small, yellow-green, panicles, bright and bright when in full bloom. According to folklore, Phoenix is fond of the phoenix tree, and Li Bai also wrote a poem "Know more about the husband and wife's wishes, and hold the chair far more than before". In fact, this is just a hope for a better life.

The ancient book says: Indus can "know leap" and "know autumn". It is said that on each branch, there are 12 leaves in normal years, 6 leaves on one side, and 13 leaves in leap years. This is an accidental coincidence, but there is no such natural law. As for "knowing autumn", it is a phenology and law. "A phoenix tree leaves, the world knows autumn" is both scientific and poetic.

Poets observe the scene of falling leaves, express their feelings through the scenery, and express endless regrets and feelings to chant their life experiences. "The chrysanthemums in bloom have fallen on the fence, and the leaves have fallen on the cold well." "The leaves of the phoenix tree have fallen in autumn, and Leng Yue is full of sorrow." In fact, defoliation is not a sign of tree aging, but when trees adapt to the environment, they enter a cold-resistant and drought-resistant dormant period, preparing for the germination of the new year.

Indus is produced in China and Japan. It likes light, deep and moist soil and grows rapidly. The fruit is divided into five sub-fruits, which are divided into boats before maturity, and the seeds are born on the edge. There are two kinds of Chinese parasol trees, one is Chinese parasol trees. One is a phoenix tree in Yunnan. The bark of buttonwood is rough, gray-black, and the leaf margin is generally three-lobed.

Sycamore tree has dense wood and fine texture, which can be used to make musical instruments and furniture. Bark fiber can be used to make paper and rope. Seeds can be eaten or pressed for oil. Leaves are used as medicine or insecticide.

The world-famous street tree "Platanus acerifolia" can be seen everywhere in parks and roadsides in China. Actually, this is misinformation. China gardener Chen Zhi named it "Platanus acerifolia". The "Platanus acerifolia" that people are used to talking about is just one kind of Platanus acerifolia. It turns out that there are 8 species of Platanus acerifolia, which are native to North America. Mexico, the Mediterranean and India. Three species were introduced to China for cultivation. There are/kloc-0 cones, 2 cones and more than 3 cones in the fruit stalk of Platanus acerifolia, so the names are different. They are called Platanus acerifolia, Platanus acerifolia and Platanus acerifolia, and they are three different species.

Why is Platanus acerifolia called Platanus acerifolia? It turns out that this kind of tree, with leaves like phoenix tree, was mistaken for phoenix tree, and "French phoenix tree" was not made in France. /kloc-In the 7th century, in Oxford, England, people used Platanus acerifolia (also known as American Platanus acerifolia) and Platanus acerifolia (also known as French Platanus acerifolia) as parents to cross into Platanus acerifolia, which was named "British Platanus acerifolia". Because it is a hybrid, there is no origin. After extensive cultivation in Europe, the French brought it to Shanghai and planted it on Joffrey Avenue (now Huaihai Middle Road as a street tree). People call it "French phoenix tree", and people follow suit and regard it as phoenix tree.

Platanus acerifolia, the parent of Platanus acerifolia, is also called Platanus acerifolia and Kumarajiva Tree. In 40 1 A.D., Kumarajiva, an Indian monk, went to China to spread Buddhism and brought this tree, which was planted in front of Huxian Ancient Temple near Xi 'an. Up to now, it takes four people to hold the trunk. This is the earliest introduced Platanus acerifolia in China. Unfortunately, this kind of three-ball Platanus has not been popularized in Xi 'an, and the street trees in Xi 'an are all two-ball Platanus introduced from Shanghai.

Another parent, Platanus acerifolia, is native to North America and has been introduced and planted in Shanghai, Nanjing, Beijing, Qingdao and other places, growing well.

At present, Platanus acerifolia is widely used as a street tree in Shanghai, Nanjing, Wuhan, Hangzhou, Qingdao, Xi and Zhengzhou.

China buttonwood is very much like poplar, very straight (which is also one of the reasons for making a zither body), with triangular leaves and generally not thick trunk. In autumn, the leaves turn pale yellow, which is very poetic. The fruit is a spherical solid fruit with a diameter of about 4-5 mm and a thin shell. You can eat it raw or fried. It smells good. Seasonal season is sold in Beijing farmers' market, but it is a waste of time. Of course it's better than your pecans in Zhejiang, like pomegranate. It's really delicious and a waste of time. China phoenix tree is not suitable for shading.

The trunk of French phoenix tree is very thick (not very thick, but thicker than China phoenix tree), and its leaves are triangular and star-shaped, but much larger. This fruit is too small to eat. Leaves turn yellow in autumn, which is definitely not as beautiful as China phoenix tree. The canopy is very large, and because the leaves are very large, it almost completely blocks the sunlight above the canopy, so it is most suitable for sidewalk shade trees.

Paulownia is a fast-growing and strongly positive tree species, which likes warmth, fertilizer, humidity and waterlogging. Its growth is inhibited above 38℃, and it is frozen at the absolute minimum temperature of -20℃, so afforestation on low-lying and waterlogged land is not easy to survive. Suitable for slightly acidic to neutral soil, calcareous soil does not grow well.
