Main points of propagation of Platanus orientalis

Platanus orientalis is often distributed in tropical and subtropical regions, and its flower suspension is its greatest feature. The hanging bell flower is shaped like a wind chime. It is very beautiful when it blossoms. It is a rare potted plant. Artificial propagation of Platanus orientalis can be done by cutting, grafting or high pressure. The editor will give you a brief introduction to the breeding methods of Platanus orientalis.

Plantago asiatica

Platanus orientalis can be cut in summer and autumn, the sturdy, full semi-lignified twigs 10Mel 15cm long, inserted in the sand bed, keep moist, generally 20 Mel after 25 days to take root.

Cuttings are mainly used to propagate seedlings in production. The cutting season of Platanus orientalis can be carried out in spring, summer and autumn except for low temperature in winter, but it is the most suitable from March to May, when the cutting seedlings can be planted the following year. Both old and young shoots can be used as propagation materials, but the seedling rate of 1-and 2-year-old branches is the highest. Cuttings cut to about 10 cm long, can be inserted into sand bed or vermiculite bed without any treatment, often moisturizing, leaves and roots can be produced in about 1 month, and the general survival rate can reach more than 80%. When the cuttings have 3-5 roots and the root length is about 3 cm, they can be moved into the nursery, watered and moisturized, managed according to conventional seedling-raising methods, and can come out of the nursery the next year.

Introduction of Malvaviscus arboreus Cav Platanus orientalis Flower: how to raise the Platanus Flower / how to propagate the Platycladus orientalis Flower Business Card Platanus Malvaviscus arboreus Cav Platanus orientalis Flower is an evergreen shrub with a shape like hibiscus, 30-60cm high, bright red flowers, more peculiar, flowering all the year round and a large number of flowers. Dangling flower is strong, like high temperature, humid and sunny environment. Originally from Mexico to Peru and Brazil, it is now distributed in tropical and subtropical regions around the world, including southern China. It is often wild, and most of it is planted in the courtyard in South China. The hanging bell flower is shaped like a wind chime, beautiful and lovely, making it a rare potted plant. Platanus orientalis is often distributed in the tropics and subtropics, including many ornamental plants and fiber plants. Therefore, it is of great significance to study the classification of Malvaceae. First of all, the anatomical diagram should pay attention to the stamen tube of the single stamen that surrounds the style, which is an important feature of Malvaceae. Secondly, attention should be paid to the morphology and structure of bract, calyx and Corolla, which are the basis for distinguishing genera and species. Plant name: Platanus orientalis alias: South American hibiscus, Lantern Fusang, Dahongpao, Hibisaceae: Malvaceae: genus Malvaceae: characteristics: evergreen shrubs, slightly resembling hibiscus in appearance, but the leaves are thicker green. Flowers are not like other hibiscus species will be fully unfolded, fresh petals spirally curled, showing a bell-shaped, pistil and stamen long protruding outside the petal bud, petals slightly left-handed, do not open bract, fish red, leaves heart-shaped, bifid or angular. The most important feature is the downward hanging of flowers. Leaves: leaves stipitate, alternate, plant tip, long oval, apex acuminate, coarsely toothed, main leaf vein palms, there are five to seven. Green. Leaves come out throughout the year, especially from March to August. Distribution of origin: Mexico, Peru and Brazil, native to South America, are now distributed in tropical and subtropical regions of the world: flowers solitary, drawn from the veins, with six to eight buds; calyx five-lobed, petals five, spiraling, slightly left, petals not spreading, budding, stamens and pistils protruding from the petals. Flower color: bright red florescence: bloom throughout the year, especially from late September to late December. Fruit: almost no fruit. Propagation methods: mainly use cutting light: like light, slightly shade-resistant uses: garden beautification, hedges, large potted plants, ornamental plants. Cultivation difficulty: easy to hang bell flower morphological characteristics of evergreen shrubs, slightly like hibiscus, but the leaves are more green; flowers are not like other hibiscus species will be fully unfolded, fresh petals spirally curled, showing bell-shaped, pistil and stamen long protruding petals outside the bud, petals slightly left-handed, fish red, leaves heart-shaped, bifid or horn-shaped. The most important feature is the downward hanging of flowers. The hanging bell flower is 30-60cm high, flowering all the year round and has a large number of flowers. Leaf blade alternate, ovate or ovate moment round, simple, sometimes lobed, leaf shape varied, leaves with stellate hairs. Flowers red, flowers usually solitary in axils of upper leaves, drooping, Corolla funnel-shaped, 5-6 cm long, five petals slightly left-handed, not unfolded, style slightly longer than Corolla. Corolla is 5 times longer than calyx, involucral bracteoles spatulate, about as long as calyx. There are conspicuous auricles at the base of the petals, the stamens gather into a column, longer than the petals, and the petals spread only slightly at the upper part, hardly bearing fruit. Leaves ovate-lanceolate, 6-12 cm long and 2.5-6 cm wide, apex long-pointed, base broadly cuneate to suborbicular, margin obtusely toothed, both surfaces nearly glabrous or only stellate sparsely pilose on veins, main veins 3; petiole 1-2 cm long, villous above; stipules linear, ca. 4 mm, caducous. Flowers solitary in leaf axils, pedicels ca. 1.5 cm, villous; bracteoles spatulate, 1-1.5 cm long, margin hirsute, base connate; calyx campanulate, ca. 1 cm in diam., lobes 5, slightly longer than bracteoles, hirsute; flowers red, pendulous, tubular, only slightly spreading distally, ca. 5 cm, staminal column ca. 7 cm; style branched 10. I didn't see it. Ringing bell flower bright red flowers, orange-red, with red veins, more peculiar, blooming throughout the year in the tropics, September to late December is in full bloom. It can be said that the sycamore is a hibiscus that does not bloom, but in fact, its petals will not open rather than blossom. To judge whether it is blooming, just look at whether the stamens protrude beyond the Corolla, and the stamens spit out the Corolla until the stamens wither. Dangling flowers can blossom all year round, orange flowers have delicious nectar, sweet. The most characteristic is that its petals are not opened, only the stamens and pistils protrude beyond the petals, and the whole flower is like a girl shyly wrapped in a red robe, so it is also called Dahongpao or rolled-petal hibiscus. The pistil divides into many small stigmas, which are sticky, and when the wind blows, it will blow the pollen on the stigma to complete their task. The flower posture is strange, the bright red petal spiral roll, the pistil and stamen long protruding outside the petal, looks like a bud, some people call it "the flower that never blooms". The hanging bell flower is shaped like a wind chime, beautiful and lovely, making it a rare potted plant. Leaves: leaves stipitate, alternate, plant tip, long oval, apex acuminate, coarsely toothed, main leaf vein palms, there are five to seven. Green. Leaves come out throughout the year, especially from March to August. Flowers: flowers solitary, extracted from leaf veins, bracts six to eight; calyx five-lobed, petals five, spirally twisted, slightly left, petals not unfolded, bud, pistil and stamens protruding from the petals. Flower color: bright red florescence: bloom throughout the year, especially from late September to late December. Fruit: almost no fruit. The ecological habits of Platanus orientalis prefer high temperature, humid and sunny environment, and are not cold-resistant, humid and slightly shade-tolerant. It is suitable to grow in fertile, loose and slightly acidic soil with good drainage, and the winter temperature is not lower than 8 ℃. It often escapes in the tropics and subtropics of Asia and Africa, and is mostly planted in courtyards in South China. Platanus orientalis has loose soil requirements and good moisture resistance. It blossoms throughout the year, but the number of flowering in winter is relatively small. Dangling flower is strong, like high temperature, humid and sunny environment, heat-resistant, drought-resistant, barren-resistant, frost-resistant, moisture-resistant, slightly shade-resistant, avoid waterlogging, and grow fast. It is suitable to grow in fertile, loose and slightly acidic soil with good drainage, and the winter temperature is not lower than 8 ℃. Keep the soil moist in midsummer, often in the sun, but keep out the hot sun. Resistant to pruning, smoke and harmful gases. It can be used for greening in polluted areas of factories and mines. Field management of Platanus przewalskii the pot of Platanus orientalis is changed every spring to add rotten leaf soil. the basin soil should be fertile, loose and well-drained slightly acidic sandy soil rich in humus. Sufficient sunshine, faster plant growth, more dense stems and leaves, more flowering; poor flowering in the shade, easy to fall off buds, or smaller flowers, dim color. Water to avoid watering the petals to avoid white spots. In cultivation, when the branches are scarce, it is necessary to prune the branches to make them have more side branches, cut off the overlong and disordered branches, weak branches and diseased branches, so as to promote new branches, so as to achieve the purpose of more germinating branches and more flowering. The adult plant is pruned regularly every spring, and the aging of the plant needs strong pruning to promote the density of branches and leaves. Pruning can root and grow if it is cut directly on the hedge ground. Potted with 20cm pot, 1 plant per pot. The row spacing of flower beds and hedges is 25*30cm. Fertilize once every semimonthly during the growing period. The soil remains moist in midsummer, with more sunshine, but to prevent hot sun exposure, spray water on the leaves sooner or later. When the weather turns cool in autumn, you should move indoors, stop fertilizing, control watering, and maintain ventilation. The key points of cultivation are changing pots every spring, adding rotten leaf soil, and pruning and shaping, so as to sprout more branches. Fertilize once every semimonthly during the growing period. The soil remains moist in midsummer, with more sunshine, but to prevent hot sun exposure, spray water on the leaves sooner or later. When the weather turns cool in autumn, you should move indoors, stop fertilizing, control watering, and maintain ventilation. The propagation mode of Platanus orientalis is mainly propagated by cutting, and it can also be grafted or under high pressure. Can be cut in summer, autumn season, strong, full semi-woody twigs 10-15 cm long, inserted in the sand bed, keep moist, generally 20-25 days after insertion can take root. Cuttings are mainly used to propagate seedlings in production. The cutting season of Platanus orientalis can be carried out in spring, summer and autumn except for low temperature in winter, but it is the most suitable from March to May, when the cutting seedlings can be planted the following year. Both old and young shoots can be used as propagation materials, but the seedling rate of 1-and 2-year-old branches is the highest. Cuttings cut to about 10 cm long, can be inserted into sand bed or vermiculite bed without any treatment, often moisturizing, leaves and roots can be produced in about 1 month, and the general survival rate can reach more than 80%. When the cuttings have 3-5 roots and the root length is about 3 cm, they can be moved into the nursery, watered and moisturized, managed according to conventional seedling-raising methods, and can come out of the nursery the next year. Disease control of Platanus orientalis Flower Leaf spot and powdery mildew often occur in Platanus orientalis, which is a fungal disease caused by fungi. Fungi are a class of lower organisms without chlorophyll, with individuals of different sizes, most of which can only be seen under a microscope. [3] Prevention and control methods: first, remove dead branches and leaves in late autumn or early spring and cut off diseased branches and leaves in time; second, spray 65% Daimen zinc wettable powder 600 times before the disease; third, reasonable fertilization and watering, pay attention to ventilation and light; fourth, spray 50% carbendazim, or 50% thiophanate 500 times, 600 times, or 75% chlorothalonil, 600 times, 800 times. There are aphids, shell insects and leaf rollers in pest control methods: spray with 1000 times of omethoate EC.

Culture methods of Lantern Flowers

Basic information of Lantern Flowers

Scientific name: Abutilon striatum alias: Golden bell flower, wind bell flower, striped abutilon, net flower, lantern flower, Chinese lantern flower, petal bell flower, wind bell flower, red vein abutilon.

Families and genera: Malvaceae, hemp.

Evergreen shrub, the tree posture is more scattered, 1-3 meters high. Leaves alternate, palmately 3-lobed, broadly ovate, petiole long. It will blossom from June to November and can blossom all the year round when the temperature is suitable. The flower is solitary between the axils of the main branch and the middle and upper part of the branch, the pedicel is slender and pendulous, the calyx is green, cup-shaped; 5 petals are not open, the petal tip is curved, semi-spreading, orange-yellow, with orange-red or red veins, the stamen column is orange-red, protruding beyond the Corolla.

The lantern flowers and branches are soft, the flowering period is as long as half a year, and the flowers are colorful, and the hanging flowers are swaying in the wind, like jingling wind bells and round lanterns hanging high among the branches with an auspicious and warm atmosphere. South China is often planted in gardens, while more potted plants are used in the north.

[Lantern flower propagation] cuttings, striping.

The main results are as follows: (1) Cuttage can be carried out in spring, rainy season and autumn, and it is better to cut in rainy season. Spring and autumn cuttings selected annual sturdy branches as cuttings, plum rainy season cut sturdy semi-mature branches as cuttings, cuttings about 15 cm long, after cutting to keep moist and shaded, after 20-30 days can take root and survive. If the cuttings survive in late June, the flowers can be seen in the same year.

(2) pressing: using the high-voltage method, from May to June.

[key points of Lantern Flower cultivation]

⑴ temperature: like warmth, the most suitable temperature for growth is 15-28 °C. The cold tolerance is stronger than that of Fusang, and it can endure the low temperature of 3 °C for a short time. Fallen leaves will occur when the temperature is low, but leaves can still sprout after the spring is warm. The overwintering temperature should be kept above 5 °C. If the room temperature can be maintained at 18 ~ 30 °C in winter, it can blossom continuously.

(2) Light: like plenty of sunlight, although it can withstand semi-shade and grow in slightly shady places, it is better for plants to grow and blossom in full sunlight and must be placed in a sunny place.

(3) watering: like the moist soil environment, not resistant to drought. During the growth period, it should be fully watered to keep the basin soil moist and not dry. After entering the flowering stage in June, more water is required, and the amount of water should be increased to meet the needs of plant growth and flowering. But also avoid water collapse, watering should not be too wet, plum rain season to pour out the stagnant water in the basin in time after the rain. It is necessary to control watering in winter, especially after low temperature defoliation, we should pay more attention to reduce watering so as not to let the basin soil get too wet.

(4) fertilization: like fertilizer, nitrogen fertilizer is applied once every half month after the plant begins to grow in spring to promote the growth and sturdiness of branches and leaves. The plant is about to enter the vigorous period of growth and flowering in late May, so it is necessary to replenish nutrients in time and apply nitrogen, phosphorus and potassium fertilizer once a month to promote multiple lateral branches and flowers, and keep the flower vigor. It is necessary to avoid the simple topdressing of nitrogen fertilizer, otherwise the branches and leaves will grow vigorously, but the number of flowers will be less; only when the plant is obviously short of fertilizer and the leaves become thin and yellow, nitrogen fertilizer should be applied properly. In September, phosphorus and potassium fertilizer was applied twice and nitrogen fertilizer was stopped. Stop fertilizing in winter.

(5) pruning: young trees should strengthen topping to promote branching. After coming out of the shed in spring, the plants should be pruned. In addition to cutting off the thin and weak branches and over-dense branches, the annual branches left should be cut short to dwarf the plants, promote branches and bloom more. The plants whose growth potential becomes worse due to aging should increase the pruning intensity, otherwise the plant growth is weak, the bud is easy to fall, and the flowering is rare.

(6) turn the basin: turn the basin once a year in spring, like fertile, moist, well-drained sandy loam, the matrix can be prepared with rotten leaf soil, peat soil, garden soil, perlite or coarse sand and other materials.

(7) pest control: there are diseases and insect pests such as leaf spot, anthracnose, red spiders, aphids, shell insects and so on.

[common problems in Lantern Flower cultivation]

The common causes of common problems are that the leaves fall in winter are usually caused by low temperature, but the branches and leaves are blooming, but the flowers are few, and the ① light is poor; the ② basin soil is too thousand or too wet; ⑤ is lack of fertilizer; and ④ has too little pruning when turning the basin.
