What kind of flower is this?

Magnolia grandiflora: Deciduous tree of Magnoliaceae. ? (Scientific name: Magnolia? Magnolia), alias magnolia, primrose and magnolia. ? Originally from the central provinces of China, it is now cultivated in Beijing and the south of the Yellow River Basin. In ancient times, it was planted in front of pavilions. Now it is more common in gardens, factories and mines, solitary planting, scattered planting, or roadside trees on both sides of the road. There are also potted plants with heaps of scenery in the north.

? Magnolia is usually called the flower of Mulan, but it actually refers to Magnolia or all the flowers under Magnolia. There are nearly 120 species of flowers in Magnolia all over the world. Strictly speaking, Magnolia refers to a large class of magnolias originating in China. Magnolia grandiflora

Magnolia in Magnoliaceae are mostly deciduous trees, and the height of trees is generally 2-5 meters or as high as 15 meters. The flowers are white to lavender, large and fragrant, and the corolla is cup-shaped. The first leaves are open, and the flowering period is about 10 days. The famous trees in China are important ornamental trees in early spring in the north. Shanghai flower. China has a cultivation history of about 2,500 years.

Magnolia photo album (20 photos) is a precious ornamental tree species in the garden. Distributed in central and southwest China, introduced and cultivated all over the world. It is usually propagated by sowing and grafting. I like warm, sunny, humid and well-drained places, and require fertile soil and no water accumulation. Strong cold tolerance, can safely overwinter at -20℃. Grow well in a better environment in Beijing. Transplanting should be done more than ten days before germination, or before leaf spreading after flowering. Seeding seedlings usually takes about 5 years to blossom. Magnolia grandiflora in Er Qiao is also common in the north. Its petals are lavender outside and white inside.

Magnolia looks like a lotus flower. When in full bloom, its petals spread in all directions, making the courtyard green and white, dazzling with white light, which has high ornamental value. Coupled with the fragrance, refreshing, it is an ideal flower pattern to beautify the courtyard.

Magnolia, also known as magnolia, primrose and magnolia; As one of the rare garden flowers and trees unique to China, it originated in the Yangtze River valley, and now it is still wild in Lushan, Huangshan and Emei Mountain. Now it is cultivated in Beijing and south of the Yellow River basin. In ancient times, it was planted in front of pavilions. Now it is more common in gardens, factories and mines, solitary planting, scattered planting, or roadside trees on both sides of the road. There are also potted plants with heaps of scenery in the north.

Morphological characteristics of deciduous trees of magnolia. Winter buds are densely covered with gray-green long hair. Leaves alternate. Flowers and leaves are open, erect, bell-shaped, fragrant, blue-white and sometimes reddish at the base. Aggregate fruit, the seed is heart-shaped, black.

Magnolia is white as jade, fragrant as orchid, with oval crown, large inverted leaves, short and sharp apex, wedge-shaped base, shiny surface and short fluff outside the branches and buds. Winter buds have large scales. Flowers bloom first, and the flowers are terminal, large, with a diameter of 12- 15 cm. Perianth 9, campanulate. The ear of the fruit is cylindrical and brown: the fruit is red when it is ripe. It blooms in early March and April, and the fruit matures in June and July. Aggregate fruit is cylindrical, red to reddish brown, and its seeds have bright red fleshy exocarp.

Magnolia is gorgeous? Magnolia grandiflora is a deciduous tree with a height of 25 meters and a diameter of 200 cm. When young, the crown is narrowly ovoid, while adult trees are broadly ovoid or loosely ovoid. The big trees in the nursery stock producing area often have obvious trunks, strong bodies, majestic majesty, strong growth potential, long branches and sparse flowers. Grafted tree species are often characterized by many branches or low branches, short nodes and dense branches, and small trees, but flowers are clustered and look flawless and enchanting from a distance. Therefore, Magnolia grandiflora from different habitats has different tastes in garden applications. In a small or closed garden, grafted species should be planted alone or in small clumps to reflect quaint interests. However, the species of seedlings should be selected in the scenic spots to reflect the rough and simple style.

Magnolia officinalis is gray, smooth and not too cracked when it is young. Magnolia is dark gray, rough and cracked. Branchlets are grayish brown. The terminal buds and pedicels are densely covered with gray-yellow long curly hair, fluffy as young rats, and the winter state is more obvious. Different tree ages have different branching habits. When young, the single bud is elongated, so the trunk is obvious and the crown is regular. After flowering, the mixed buds of leaves and branches extend in two or more branches after the ear, and the lateral development is more than vertical growth, so the crown develops in the direction of wide ellipse.

Leaves alternate and sometimes spiral, ranging from obovate to obovate in width, 10- 18 cm in length and 6- 12 cm in width. The apex is round and wide, flat or slightly concave, with short spikes, so it is also called Magnolia grandiflora. Taper and wedge below the middle, entire. Magnolia leaves usually have stipules or appendages at the base, and there are two kinds of stipules. The stipules at the end of the branches are attached to the young stems and separated from the petioles, which are covered with tiles. The stipules on the leaves are scattered, tile-knife-shaped, attached to both sides of the petiole base, with long buds, stipules falling off and annular stipules left on the young branches, which are the distinguishing characteristics of Magnoliaceae trees.

Biological habit Magnolia likes light, is cold-resistant, and can overwinter in the open air. Love high dryness, avoid low humidity, and waterlogging in planting land is easy to rot roots. Fertile, well-drained and slightly acidic sandy soil can also grow on weakly alkaline soil. In the south where the temperature is high, flowers can bloom in February 65438-1October 65438. Magnolia is more resistant to harmful gases. If this flower is planted in a factory polluted by sulfur dioxide and chlorine, it has certain resistance and sulfur absorption ability. Artificial smoking with sulfur dioxide can absorb more than 0.6 grams of sulfur per kilogram of dry leaves. Therefore, Magnolia grandiflora is a good anti-pollution greening tree species in air pollution areas.

Edit the reason why this paragraph blooms for the second time. Lan Lina's oil painting Magnolia in Full Bloom [2] When Magnolia transits from vegetative growth period to reproductive growth period, it will blossom under suitable conditions. However, when the change of external environment affects the normal growth or genetic characteristics of plants, plants will bloom for the second time under the condition of abnormal flowering period.

The flower buds of Magnolia grandiflora differentiated years ago. After a period of low temperature, they will bloom naturally when the weather gets warmer. If the management methods of water, fertilizer, light and temperature are basically the same, some plants have secondary flowering, which is roughly due to the following reasons: (1) root damage causes great changes in hormone levels in the body, thus promoting the expression of flowering genes; In spring, plants are in the environment of sudden increase in temperature, so a considerable number of buds are in diapause and do not bloom for the time being; The materials of propagating plants are too different, and it is easy to bloom again near the area with great genetic potential for flowering; The plant has a mutation, so its flowering characteristics are time-biased compared with the original species. This kind of situation is rare, and it will take several years to draw a conclusion.

Variety situation Magnolia is blooming 5 Magnolia is a subtropical tree species, which likes light but is slightly tolerant to shade. Cold-tolerant, able to overwinter in Beijing. I like fertile, moist and well-drained soil. Fleshy root, not resistant to stagnant water. Flowers bloom first, then leaves. The flowering period is February-March, and the fruit maturity is August-September. Seeds have embryo dormancy.

Magnolia grandiflora var. Purourescens is a kind of tree with reddish flowers, purplish red surface and fragrance.

Similar species are: M.amoena, with pink or light pink flowers and greenish branchlets, native to Tianmu Mountain, Zhejiang Province. Magnolia grandiflora (M.zenii) originated in Bao Hua, Jurong, Jiangsu Province, with white flowers at the top, purple veins at the bottom and purple shoots. Magnolia, with white flowers, long stems, oval leaves and white powder and fur on the back.

The flower language magnolia stands for gratitude. Magnolia often blooms a large round white flower in a green place. With the rich fragrance, people feel an unspeakable temperament, which is really fresh and lovely. Because of its tall plants, high flowering position, swaying in the wind, full of vitality, just like a beautiful girl, very cute. New poetry is old and ugly, and Jiangnan barren museum is separated by autumn clouds. Affectionate does not change color year after year, and the eternal heart holds the gentleman.

Edit the legend of this flower Yulan The legend of Yulan runs through the traditional folk stories in China. The story is about three sisters who lived in the mountains a long time ago. My sister's name is Magnolia grandiflora, the second is Magnolia grandiflora, and the third is Huang Yulan. One day, when they went down the mountain to play, they found cold water and autumn smoke in the village. The three sisters were very surprised. Asked the people in the village, I realized that it was Qin Shihuang who rushed to fill the sea and killed the lobster princess. Since then, the Dragon King and Zhangjiajie have become enemies. The Dragon King locked the salt storage and prevented Zhangjiajie people from eating salt, which finally led to a plague and many people died. The three sisters were very sympathetic to them, so they decided to help them beg for salt. But how easy is it? After being rejected by the Dragon King many times, the three sisters had to start with the general crab guarding the salt storehouse, charmed the general crab with their own flowers, took the opportunity to cut through the salt storehouse and immerse all the salt in the seawater. The people in the village were saved, but the three sisters were turned into flower trees by the Dragon King. Later, in order to commemorate them, people called this flower tree "Magnolia", and the flowers they brewed became their own fragrance. The story is simple and beautiful, but it also reflects people's pursuit of beautiful things and their yearning for perfection.

Edit the cultivation management of this paragraph. Magnolia grandiflora is a fragrant flowering tree species in early spring. When planting, we should seize the opportunity, neither too early nor too late. It is most suitable to plant before germination in early spring 10 day or after flowering and before flowering. When transplanting, regardless of the size of the seedlings, the roots must carry mud balls, and try not to damage the roots. In order to ensure survival. Before planting, fully decomposed organic fertilizer should be applied in the hole as base fertilizer. After planting, seal the soil tightly and water it in time.

Growth management Yulan prefers fat meat, but avoids big fat meat; Generally, applying fertilizer twice in the growth period is beneficial to flower bud differentiation and promoting growth. Once in early spring and once in May-June. Fertilizers are mostly fully decomposed organic fertilizers. Newly planted saplings don't need fertilization until the leaves fall or the next spring. The root system of Magnolia grandiflora is fleshy and intolerant of stagnant water. It is advisable to keep the soil slightly wet at flowering stage. After autumn, it is necessary to reduce watering, delay the rooting of Magnolia grandiflora, and promote the maturity of branches to facilitate wintering. Generally, it is not watered in winter, and only once the soil is too dry.

Prevention and pruning of pests and diseases common pests and diseases of Magnolia grandiflora: anthracnose, leaf spot, fried cicada, red wax scale, fly scale, red spider, giant salamander, longhorn beetle and so on. Once found, they can be sprayed with drugs. However, some longicorn beetles eat branches and roots, sometimes killing trees. If wood chips and insect dung are found, look for wormholes, put cotton balls into the wormholes with dichlorvos stock solution, and then seal them with mud.

(1) Fried cicadas. The nymph of this insect sucks the root juice of flowers in the soil, the adult sucks the juice of main leaves, and the female will insert the ovipositor on the branch to lay eggs, resulting in the death of the branch.

Prevention and control methods:

(1) Search and kill the newly unearthed mature nymphs in time.

(2) If it happens a lot, can it be on the trunk at night in hot summer weather? Light a fire near the magnolia and shake the branches, so that cicadas will be killed by fire and cicadas falling outside the fire will also be killed.

(3) Coat sticky tung oil or sticky dough kneaded with cobwebs on the rod head to catch adults. (4) patrol and cut off spawning branches in time from April to August.

(2) red wax scale. The nymph and adult of this insect suck flower juice, and its excrement often induces the occurrence of sooty blotch, which makes the leaves form a layer of black mold or a thick black film, making the whole plant a black tree, with weak plants, gaunt trees and little or no flowering.

Prevention and control methods:

(1) in winter and early spring, combined with pruning, remove some branches with pests.

(2) If the injured flowers are few and short, they can be scraped off manually in winter and spring.

(3) In the peak period of nymph hatching, spraying 25% dimethoate EC with 100 times solution or 40% omethoate EC 1500 times solution, spraying 1 time every 4-6 days, and spraying for 3 times can be effective.

(4) When introducing flower seedlings, carefully check them to prevent insects from being brought in.

(3) blowing cotton. See the prevention method of blowing off scale in Peony Flower.

(4) Starscream. The red spider, Tetranychus cinnabarinus, is found in the control of Tetranychus cinnabarinus in Riley.

Magnolia branches have poor wound healing ability and are generally not trimmed. However, in order to make the tree shape reasonable, in the early stage of leaf opening, long branches, dead branches, pest branches and branches that hinder the beauty of the tree shape should still be cut off. In addition, after the flowers wither, if no seeds are left, the residual flowers and fruit ears should be cut off to avoid consuming nutrients and affecting the next year's flowering.

There are many kinds of magnolia in the ground, and potted plants should be cultivated into piles.

Edit the sowing technology of Magnolia grandiflora cultivation and propagation in this paragraph: The sowing technology of Magnolia grandiflora is very simple, but every point should be paid attention to. The first is seed selection. Only good magnolia seeds can sow good seedlings, so seed selection is very important. The second is seed treatment technology. Magnolia officinalis seeds need to be soaked in warm water. Magnolia seeds are naturally wrapped in an oily afterbirth. Only by soaking in warm water can this kind of afterbirth be easily removed. Thirdly, the seeds of Magnolia grandiflora also need sand storage, because sand storage will make the emergence rate of Magnolia grandiflora seeds higher. The fourth is the selection of magnolia seed seedbed, which is also very important. Generally, large seed companies will provide a magnolia planting technology when selling magnolia seeds. An online company called Wanguo Nursery has done a good job in this respect, and the seeds are good. Detailed sowing information is best provided by enterprises!

Propagation methods of Magnolia grandiflora include grafting, layering, cutting and sowing, but grafting and layering are the most commonly used methods.

(1) Grafting propagation. There are two grafting methods, one is butt joint and the other is cutting.

Docking: docking time, from spring to autumn, can be carried out throughout the growing period. Mostly in April-July. The best abutting position is 70 cm from the ground. After binding, wrap it in mud and leaves to prevent the rain from washing away. It can be cut off in about 60 days. Docking is an easy way to live, but it is not as vigorous as cutting. ? Magnolia grandiflora (2) layering propagation. There are also two kinds of layering propagation: ordinary layering and high-branch layering.

① General stratification: stratification is best carried out in February-March. Cut the root of the branch to be pressed half deep, then cut it up for a while, and then press a tile in the middle, so it won't break. Insert a thick U-shaped iron wire into the soil, fix it to prevent it from lifting, and then pile it on the soil. Layering in spring, and cutting and planting after the root buds are sent out.

② High-branch layering: Before lodging, select healthy and disease-free shoots (diameter 1.5-2cm) on the mother plant, cut cracks at the lower part of the pot fork, then cover it with a bamboo tube or bottomless pottery jar, fill it with culture soil, and tie it tightly with a string outside, be careful not to touch it, and spray a small amount of water frequently to keep it moist. New roots can be born around May of the following year, and then they can be taken off for colonization.

Planting technology Mulan prefers sunny and humid environment, and it is not suitable for long-term growth in alkaline soil. Planting should choose a place that is sheltered from the wind and sunny, well drained and fertile. There should be enough water and fertilizer before flowers to make them big and fragrant. Magnolia grandiflora has few branches, and generally does not need pruning except dead branches, pests and diseases branches and branches that disturb the tree shape. If the flowers wither without leaving any seeds, cut off the fruit to avoid consuming nutrition. Magnolia grandiflora has strong cold tolerance and can overwinter in the open air in North China and the southeastern part of China.

Potted Magnolia grandiflora can be coiled, that is, after germination in April, with the growth of new shoots, it can be coiled at any time and tied into an arc posture to limit the height of the trunk. Because magnolia is a deep root system, it is easy to grow and weaken after a long time in the pot. Therefore, after the flowers wither, it is necessary to repair the taproot, cultivate it in the field, and then put it in a pot before the flowers, so that there can be more flowers and more flowers.

Magnolia grandiflora is mainly propagated by grafting, but also by sowing, cutting and layering. The seedlings of Magnolia grandiflora are often used as rootstocks for grafting, and they are cut before Tomb-Sweeping Day. In the south, it can also be cut around the autumnal equinox or germinated in August-September. Cutting and budding are the same as common flowers and trees. Will the seedlings planted at the end of September or at the beginning of 10 mature? After picking the fruit, take out the seeds, soak them in plant ash water for 1-2 days, then rub off the waxy aril, and then wash them with clear water to sow; You can also clean the seeds and store them in wet sand, otherwise the germination ability of the seeds will be easily lost. In March of the following year, indoor potted plants can be planted, and seedlings can emerge in about 20 days.

Medicinal value Magnolia grandiflora is the flower of Magnolia grandiflora, a deciduous tree of Magnoliaceae, which opens in early spring and March and is rarely used or dried. Magnolia grandiflora is a valuable ornamental plant with large and beautiful flowers, and it smells fragrant when it is open. Its petals are edible, with thick meat and unique fragrance. The "Flower Mirror" in the Qing Dynasty said: "Its petals are washed clean, the noodles are fried perfectly, and it can also be dipped in honey." Magnolia grandiflora contains volatile oil, mainly citral, clove oleic acid and so on. It also contains magnolin, alkaloid, primrose, decanoic acid, rutin, oleic acid, vitamin A and other ingredients, which has certain medicinal value. Flos Magnoliae is pungent and warm, and has the effects of expelling wind and cold, dredging orifices, dispersing lung and dredging nose. Can be used for treating headache, blood stasis dysmenorrhea, nasal congestion, acute and chronic sinusitis, allergic rhinitis, etc. Modern pharmacological research shows that Magnolia officinalis has inhibitory effect on common skin fungi.
