Indus leaves are bitter; Cold, expelling wind and removing dampness; Detoxification and detumescence; Lower blood pressure.
Indus wood is light and soft, which is a good material for making wooden boxes and musical instruments. The seeds are fried and eaten or pressed with oil, and the oil is non-drying oil. The fiber of bark is white and can be used for papermaking and rope weaving. Wood shavings can leach out mucus, which is called wood shavings moistening hair. As a soil insecticide, leaves can kill aphids and have strong resistance to toxic gases such as sulfur dioxide and chlorine. Of course, buttonwood has no special function to the environment and human beings, that is, greening and purifying the air, but its seeds can be eaten, used to extract oil and used as medicine. Maple contains caffeine and gum. Functions: benefiting qi and nourishing yin, improving eyesight, calming liver and blackening hair. 【 Tinea capitis, alopecia (lump) 】 Mash the fresh Chinese parasol flower and apply it to the affected area. [Rectum] Platanus acerifolia bark is decocted with thick juice and washed warmly, 2~3 times a day. [Hypertension] Young leaves of Chinese parasol tree, 30g per day, decocted in water instead of tea. Glossitis: the combustibility of peach is ground into fine powder and coated with honey several times a day.
Platanus acerifolia is easy to cultivate, simple to manage and very water-saving. Propagation methods are: sowing, cutting and rooting. Sowing method: harvest the fruit when it is ripe in autumn, sow it in autumn after drying and threshing, or sand sow it until the next spring. The row spacing of drilling holes is 25 cm, the thickness of covering soil is about 1.5 cm ... and the sowing amount per mu is about 15 kg. Seeds germinate regularly, 4-5 weeks after sowing. Dry-stored seeds often germinate unevenly, so they can be soaked in warm water before sowing to accelerate germination. Under normal management, the photo collection of seedlings in that year (10) can reach more than 50 cm, and then they will be planted separately in the next year. Three-year-old seedlings can leave the nursery. The planting place should be chosen in a high and dry place, and base fertilizer should be applied in the hole. After drying, the incision should be sealed with wax. In the north, young trees should be wrapped with straw ropes to keep out the cold in winter. Fertilize once in winter and once in early spring. There are many basins in the Yangtze River and the Pearl River. Positive tree species, born in a warm and humid environment; Cold tolerance, drought tolerance and barren tolerance. Bark can't stand the hot summer sun. It grows well on sandy soil.
Among them, Platanus acerifolia only harms Platanus acerifolia and is distributed in Shandong and Henan provinces. If the insect is harmful, it will secrete white cotton wax, block the stomata on the leaves, affect the normal photosynthesis and respiration of the leaves, make the leaves look pale and atrophy, fall off early, dry branches, rough and fragile epidermis, and be vulnerable to wind folding. Prevention and control methods: clear water can be sprayed to wash away flocs in the harmful period, which can kill many nymphs and adults, and 8 times 65% soap petroleum emulsion can be sprayed in early spring to prevent them from overwintering eggs. Lepidoptera moth harms trees such as phoenix tree and magnolia tree. 40% chlorpyrifos EC can be injected 400 times into the damaged tunnel with a veterinary syringe to poison the larvae. It can also be controlled by petroleum emulsion, dichlorvos, dimethoate and methamidophos.

Brief introduction of French phoenix tree
Platanus acerifolia, a world-famous street tree, can often be seen in parks and streets in China. Now it is cultivated in Dalian, Beijing and Hebei in the north, Shaanxi and Gansu in the west, Sichuan and Yunnan in the southwest, Guangdong in the south and coastal provinces in the east. In Nanjing, people call it "Fatong" or "Fawu" for short, but it is neither a French phoenix tree nor a French phoenix tree, and the French phoenix tree we often say actually refers to "China phoenix tree". 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. It can be summarized as: 1, Platanus acerifolia (native to North America, commonly known as "Platanus acerifolia" or "Platanus acerifolia") 2, Platanus acerifolia (commonly known as "Platanus acerifolia" or "Platanus orientalis") 3. Branches spread outward and the crown is broad and rectangular. Bark is grayish green or grayish white, peeling off, and after peeling off, it is pink green and smooth. Near-species buds, simple leaves alternate, big leaves, palmately 5-9-lobed, densely stellate pilose when young, and then shed. Flowering from April to May, the head is spherical. Cones droop, usually two balls in a string. In September, the fruit ripens-10, and the nut has long hair at the base. Leaf blade triangular, 9-15cm long, 9-17cm wide, 3-5 palmately divided, with irregular sharp teeth and wavy teeth at the edge, truncated or nearly heart-shaped at the base, stellate hairs when tender, and nearly hairless at the back. Globular inflorescence 2 in diameter. 5-3.5 cm, usually 2 in a string, shaped like a bell; The flower is about 4 mm long; Sepals 4; Petals 4; Male flower; Male flowers have 4-8 stamens; The female flower has six independent carpels.
Brief introduction of China phoenix tree
Firmiana simple, namely "China phoenix tree", is a phoenix tree, which is also a deciduous tree with a height of15m. The trunk is straight and the bark is green and smooth. Originally from China, it is cultivated in all provinces in the north and south, and it is also a common street tree and landscaping ornamental tree. "Flower Mirror": "Wu Tong, also known as Qingtong. The skin is green, the leaves are short of flowers, elegant and clean. The flowers in April are bright yellow and as small as jujube flowers. As a result in May and June, the pedicel is three inches long and has five edges. The seeds are decorated on it, ranging from five or six to two or three, as big as soybeans. " China phoenix tree likes light, deep and wet soil and grows fast. 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 in China, one is Chinese parasol tree, and the other is Chinese parasol tree. The bark of buttonwood is rough, gray-black, and the leaf margin is generally three-lobed. The buttonwood trees in China are tall and burly, with knotless trunks, upright and upright, lofty and a huge green umbrella like emerald, 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 tree with green leaves stands erect in Chiba, Lv Yun Municipal Committee", vividly depict the verdant branches of China phoenix tree and the swaying shade of tung tree. China phoenix tree is also 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. There is another interesting saying about China phoenix tree, Li's story, to explain it to you: China phoenix tree 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. China buttonwood bark is turquoise and smooth. The leaves are heart-shaped, palmately 3-5-lobed, with a diameter of 15-30 cm, triangular lobes, tapering at the top, heart-shaped at the base, glabrous or slightly pubescent on both sides, 7 basal veins, and the petiole is as long as the leaves. The panicle is terminal, about 20-50 cm long, the lower branch is 12 cm long, and the flowers are yellow-green; Calyx 5 deeply divided to base, sepals strip-shaped, curled outward, 7-9 mm long, externally pubescent with yellowish color, only the base is pilose; Pedicels are as long as flowers; The pistil of the male flower is as long as the calyx, and the lower part is thick and hairless. The anthers of 15 gather irregularly at the top of pistil, and the degenerated ovary is pear-shaped and very small. The ovary of the female flower is spherical and hairy. Follicles are membranous, stipitate, and split into leaves before maturity, with a length of 6-1 1 cm and a width of 1.5-2.5 cm. The outer surface is short or almost hairless, and each hair follicle has 2-4 seeds. The seeds are spherical with wrinkles on the surface and about 7 mm in diameter. The flowering period is from June to July, and the fruit ripens in10-165438+1October.
Main differences between French phoenix tree and China phoenix tree
The buttonwood tree in China is very similar to poplar, very straight (it can be used as a zither), with triangular star-shaped 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's only the size of a pea, and it tastes like a pea. It tastes delicious and can be picked in seasonal seasons. The trunk of French phoenix tree is very thick (not very thick, 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. [5]
Edit the historical records and legends related to this phoenix tree.
Wu Tong 1. Because Wu Tong is tall and straight, it is the crown of trees. It has been valued since ancient times. It is often associated with the phoenix. Phoenix is the king of birds. Phoenix is most willing to inhabit the phoenix tree, which shows how noble the phoenix tree is. Historical records about Chinese parasol trees: Chinese parasol trees are called Qingtong, Wu Bi, Sapphire and Wu Ting. It was first seen in the pre-Qin literature "The Book of Songs", and the words "Feng Huangming Yi, Yu Pi Gao Gang" were written in "Yali Life Juan A". The phrase "Wu Tong was born in the morning sun" became the earliest source of the legend of attracting phoenix in Wu Tong. It shows that at the end of summer and the beginning of Zhou Dynasty, the plane tree was valued by people at that time. Later pre-Qin documents, such as Shangshu, Zhuangzi and Lv Chunqiu, all mentioned buttonwood. In the Spring and Autumn Period, Fu Cha, the king of Wu, built a garden and planted trees in it. Fang Shuo Wen Jie Zi said: "Wu Tong Garden is martial arts, and Fu Cha, the old garden of the king of Wu, is also Qinchuan". Indus was planted in the palace of Han Dynasty. "Miscellanies of Xijing" contains "There are Tongsan, Yitong, Wu Tong and Jingtong in Shanglin Garden" and "There are three phoenix trees in Gongxi, Zuo Wu". During the Wei and Jin Dynasties, the planting of buttonwood trees began to increase. Jin Xiahou Zhan's Futong says, "There is a humble bed in the south, and beautiful tung trees are planted in the vestibule." Xie Tiao, a famous scholar in the Southern Dynasties, wrote the poem "You Dong Tang Yongtong": "The solitary tung is more than 100 feet high outside the window; The phrase "leaves are graceful and sparse" means planting tung trees in the yard. Fu Cheng's "Wu Tong Fu" tells the grand occasion of planting trees in front of the door to attract phoenix, including: "Trees in rows, two doors side by side." Fu Jian, the former king of Qin, planted plane trees on a large scale. "Notes on Fu Jian in the Book of Jin" records that "phoenix is not a phoenix tree, bamboo is not food, and hundreds of thousands of tung trees are planted in Afangcheng". The Book of Qi Yao Min, written by the Northern Wei Dynasty, said that "it will be beautiful, elegant and lovely in the middle of March next year before it is transplanted to Tingzhai". In the Tang Dynasty, it was very common to plant buttonwood trees. The Story of Sui and Tang Dynasties records: "In the early Tang Dynasty, there were few trees. After filial piety, I was ordered to plant poplars ... or even more trees." Plant buttonwood trees in the palace. Duan Youyang Miscellaneous said: "Licheng (now Jinan) is the residence, the mountain pool of Qiboling Junbao, and there are miscellaneous trees in it? Someone once broke its tung branches, and it was a public day: my phoenix was hurt, and future generations would never dare to break it. " It is planted in a private garden. Li He's poem "A Ballad in the Sky" and "Qin Fei's northern dawn blinds, a small phoenix planted in front of the window" are the portrayal of planting buttonwood trees in the courtyard. Many buttonwood trees were also planted in the Song Dynasty. In the Northern Song Dynasty, Zhu established a music garden in Suzhou. His book "The Story of the Music Garden" said that trees such as sycamore and pine and cypress were planted in the garden, which meant that "the leaves of each family are in harmony with the wind and hurricane, and they are high or towering." Li's "Luoyang Famous Garden" in the Northern Song Dynasty contains Luoyang Famous Garden 19, where there are many phoenix trees, the most famous of which is Cong Chunyuan, and "all tung trees and cypresses are listed". Ji Xu's poem "Huazhou Taishou Garden" is a sentence of "Indus planted, Danshan will come next time", which describes the situation of planting Indus for landscaping in Guanzhou City Guanyuan. In the Yuan Dynasty, there were phoenix trees in the courtyard, which were used for landscaping, as evidenced by Yuan poetry. For example, Ding Henian's poem "Phoenix Pufang Five Bamboo Pavilions", "Phoenix Wu once heard of this place, so far there are five bamboos all over the mountain", and Xing Wu's poem "Wu Bi Cuizhu Hall". "Tung trees were planted last year, with high green leaves and cool clouds", all of which are descriptions of the landscaping of Chinese parasol trees in the Yuan Dynasty. In the Ming Dynasty, plane trees were often planted in front of courtyards, windows, doors and sidewalks. Wang's "Pavilion Group Fangpu" said: "Indus" has green skin, leaves are short of flowers, elegant and elegant, pleasing to the eye, and people have various pavilions. Chen Jiru's "Small Window" has a configuration for buttonwood trees in the courtyard: "Where there is a quiet room, plant green trees in front and bamboo trees in the back. Put a step on the front eaves, use dark windows in the north, close them in spring and summer to avoid wind and rain, and open them in summer and autumn to cool down. However, Wu Bi's taste: falling leaves in spring and summer, the joy of freedom and harmony; In summer and autumn, shade is used to cover up the fierce power of inflammation and steam. Humble Administrator's Garden is a famous private garden in Suzhou, which was built in the Ming Dynasty. There is a scenic spot of "Wuzhu secluded pavilion" in the garden, and there are phoenix trees and bamboo forests next to it. Now the buttonwood trees have become ancient trees. At the end of the Ming Dynasty, several phoenix trees were also planted in Yangzhou's famous private gardens and cinemas. In the Qing dynasty, the enthusiasm for planting buttonwood remained undiminished. Chen Fuyao's "Flower Mirror" said that the landscaping of the buttonwood tree is "hidden by vines, and the bamboo tree is quiet, so it is appropriate to go to the deep courtyard and have a quiet pavilion." During the Kangxi period, Gao Shiqi, a famous Zhejiang scholar, built Jiangcun Caotang Garden in Pinghu, Jiaxing, where he lived in seclusion. There is a scene of "Wu Bi Road" in the garden, and its work "Jiangcun Caotang Collection" records that the scene is "Wu Bi Road is behind, and everyone who goes down is dressed. When the dew is clear, the new branches are introduced at the beginning; Light and cool, then a leaf floats; There are all kinds of villas, and there are many here. " Li Dou's "Yangzhou Boat Story" recorded the scenic spot of "Xiahong near the water" as "Xuan Tong is behind Feixia Building, and there are many phoenix trees in the ground". In addition, gardens in Yangzhou Zhang's former residence, Shuangtong Bookstore and Malipo are also famous for planting phoenix trees. After entering the modern era, Platanus acerifolia is widely planted all over the country, and can be seen in institutions, schools, factories, parks, scenic spots and streets. 2. Legend about the King of Wutong Tree in Hotan, Xinjiang: Some local people say it was introduced from India. There are also many local myths and legends related to this tree, which are full of mystery and arouse people's desire to see the tree. People who believe in Islam have always regarded it as a "holy tree" and people often go to worship. This ancient Platanus acerifolia is of great research value in geography and botany. At present, it has become an important tourist attraction in Hotan. [4] Because the ancients often associated the phoenix with the phoenix, people now often say, "If you plant a plane tree, there will be a phoenix." . So in the past, buttonwood was often planted in the yard, not only because it was majestic, but also because it was a symbol of good luck.

There are many images and meanings in China's ancient poems. 1, the image and meaning of noble character. Indus symbolizes noble and beautiful character in ancient poetry. Such as "Feng Huangming Yi", in Jeremy goldkorn. Wutong was born in Chenyang ("The Book of Songs, Elegant Volume I"), and the poet chimed the bells with the phoenix, singing over the hills; The phoenix tree grows wildly, covered with brilliant sunrise, symbolizing noble and beautiful character. Another example is "hanging down and drinking clear dew, listening to sparse tung." It's not the autumn wind that makes you aloof "(Yu Shinan's Cicada). This poem, with tall and straight buttonwood trees and sparse green leaves as the shelter of cicadas, describes the nobility of cicadas and implies the beauty of their own character. Zhuangzi also said in Autumn Water: "Husband and wife originated in the South China Sea and flew to the North Sea, which is not a phoenix tree. "Stork is a kind of bird called phoenix in ancient books. It was born in the South China Sea, but flew to the North Sea, and only the phoenix tree was its shelter. The phoenix tree here is also a symbol of nobility. Therefore, there is an ancient saying that "planting tung attracts phoenix". 2. The image and significance of faithful love. According to ancient legends, the phoenix tree is a male tree, the tung tree is a female tree, and the phoenix tree lives and grows with the old, and lives and dies together. The phoenix tree has tall and straight branches and deep roots. In the poet's pen, it became a symbol of faithful love. Such as: "Raqqa trees are ripe in pairs, and mandarin ducks die side by side." (Tang Meng Jiao's Brave Woman's Mothers) Another example is "Plant pine and cypress in the east, phoenix tree in the left and phoenix tree in the right. The branches are covered and the leaves are communicating. " (Peacock flies southeast) The poem is covered with branches and leaves of pine, cypress and phoenix trees, symbolizing the loyalty of Liu Lanzhi and Jiao Zhongqing to love. The couple, who pursued pure love and resisted feudal ethics, were forced to separate before they died and buried together in Jiuquan. Can it not be shocking? 3. The image and significance of loneliness and sadness. The wind blows the leaves, and the raindrops are phoenix trees, which is a sad scene. Indus has become a lonely and sad image in literati's works. Such as "lonely west wing, bright moon like a hook. The Lonely Wutong Deep Courtyard Locks the Clear Autumn (Li Yu's "Hui Huan") vividly describes the loneliness of the monarch who perished in the lonely deep courtyard. The heavy door was locked, and Gu Ying lingered. Only the cold moonlight shed from the cracks in the branches and leaves of the phoenix tree. How sad! He used to be the monarch above all others, but now he is a prisoner, full of sorrow. When is the hatred of national subjugation? Another example is "autumn leaves are a little banana and a little sorrow" (Xu Zaisi's Narcissus Night Rain). On the lonely night in late autumn, the night rain dripped on the phoenix tree and banana, and every sound made the lovesick people generate leave Qiu Si and feel disappointed. This is not only a lovesick song on a rainy night, but also a picture of a beautiful autumn night! Faced with this situation, the pain of acacia rose from the poet's heart. The author's description of the rain-beaten indus plantain is full of emotion, mixed with scenes, sad and confused, and far-reaching in artistic conception. 4. In Tang and Song poetry, the images and meanings of parting love are the most. For example, in Bai Juyi's Song of Eternal Sorrow, "Peach and plum blossom, the spring breeze blows, the autumn rain falls, and the willow blossoms bloom", the poet compares the past grand occasion with the present desolation, and depicts the desolate scene after Tang Gaozong lost Yang Guifei because of the Anshi Rebellion. Emperor Tang Ming returned to the palace, witnessed the past and moved the scene. Where is the beauty of the past? By comparing the scenery in spring and autumn, the poet alludes to the lifelong regret brought by the lingering beauty of the monarch. Such as "buttonwood, it rains in the middle of the night, and it is bitter to leave." A leaf, a sound, empty footsteps dripping on Ming "(Wen," More Leakage "), in autumn night, cold raindrops fell on the leaves of the plane, a woman living alone in the autumn boudoir, her fragile and sensitive heart could no longer bear the pain of parting, lingering, bitter and sad, and sleepless all night. Its significance is profound and unforgettable. Another example is "phoenix tree raining, dripping at dusk." "How can I get a sad word this time?" (Li Qingzhao's "Slow Voice", Li Qingzhao, who lives alone after her husband's death, suffers from the pain of national ruin and death. At this time, the poetess stood at the window of independence, the rain whipped the phoenix tree, her voice was desolate and lonely, and she deeply missed her husband. These sad words make people cry, which can be called the swan song of writing sadness. Platanus acerifolia is easy to cultivate, simple to manage and very water-saving. Propagation methods are: sowing, cutting and rooting. Sowing method: harvest the fruit when it is ripe in autumn, sow it in autumn after drying and threshing, or sand sow it until the next spring. The row spacing of drilling holes is 25 cm, the thickness of covering soil is about 1.5 cm ... and the sowing amount per mu is about 15 kg. Seeds germinate regularly, 4-5 weeks after sowing. Dry-stored seeds often germinate unevenly, so they can be soaked in warm water before sowing to accelerate germination.

Platanus acerifolia is easy to cultivate, simple to manage and water-saving. Under normal management, the seedlings were tall in those years.
The photo collection of Platanus acerifolia (10 photos) can reach more than 50 cm, and it will be planted again every other year. Three-year-old seedlings can leave the nursery. The planting place should be chosen in a high and dry place, and base fertilizer should be applied in the hole. After drying, the incision should be sealed with wax. In the north, young trees should be wrapped with straw ropes to keep out the cold in winter. Fertilize once in winter and once in early spring. There are many basins in the Yangtze River and the Pearl River. Positive tree species, born in a warm and humid environment; Cold tolerance, drought tolerance and barren tolerance. Bark can't stand the hot summer sun. It grows well on sandy soil.
Edit the common pests and diseases in this paragraph and their prevention and control
The main pests are psyllid, frost moth, thorn moth, furuncle moth and so on. Among them, Platanus acerifolia only harms Platanus acerifolia and is distributed in Shandong and Henan provinces. If the insect is harmful, it will secrete white cotton wax, block the stomata on the leaves, affect the normal photosynthesis and respiration of the leaves, make the leaves look pale and atrophy, fall off early, dry branches, rough and fragile epidermis, and be vulnerable to wind folding. Prevention and control methods: clear water can be sprayed to wash away flocs in the harmful period, which can kill many nymphs and adults, and 8 times 65% soap petroleum emulsion can be sprayed in early spring to prevent them from overwintering eggs. Lepidoptera moth harms trees such as phoenix tree and magnolia tree. 40% chlorpyrifos EC can be injected 400 times into the damaged tunnel with a veterinary syringe to poison the larvae. It can also be controlled by petroleum emulsion, dichlorvos, dimethoate and methamidophos.

Main differences between French phoenix tree and China phoenix tree
The buttonwood tree in China is very similar to poplar, very straight (it can be used as a zither), with triangular star-shaped 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's only the size of a pea, and it tastes like a pea. It tastes delicious and can be picked in seasonal seasons. The trunk of French phoenix tree is very thick (not very thick, 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. [5]
