Introduction to the common propagation methods of begonia in four seasons

The seeds of four seasons begonia are small and have a short life span. If the seeds collected are not sown in time, it will have a great impact on the emergence rate. In general, four Seasons Haitong propagates mainly through sowing and cutting. The editor will give you a brief introduction to these two breeding methods of Siji Haitong.

Begonia semperflorens

1. Sowing method: East China is generally the most suitable in April-May in spring and August-September in autumn. The seeds should be evenly removed and sown on the fine mud in the basin (no need to cover the soil). Then use the sowing pot to absorb enough water, then cover a piece of glass and put it in a half-shaded place, which can sprout after 10 days. The seedlings sown in spring can blossom in the autumn of that year.

2. Cutting method: cutting is mostly carried out in March-May or September-October, using plain sandy soil as cutting substrate, or directly cutting on plastic flowerpots, and the nodes need to be inserted into the soil. Under the condition of shade and heat preservation, it can be rooted in more than 20 days. Perennial old plants can split them and prune them at the same time to promote the development of new lateral branches to form an intact plant shape.

Four Seasons Begonia Bedding begonia Picture Guide of four Seasons Begonia: how to raise four Seasons Begonia / how to Propagate four Seasons Begonia Business Card four Seasons Begonia Bedding begonia Culture methods and points for attention four Seasons Begonia (Begonia semper.norms) is a genus of begonia, native to Brazil, perennial herbs, also known as begonia, tiger's ear crabapple, melon seed begonia, glass crabapple. Four Seasons Begonia is a perennial greenhouse potted flower in traditional production. In recent years, it has been applied to the layout of flower beds with excellent results. With the emergence of some relatively heat-resistant varieties, Begonia is likely to become one of the most important flower beds in China, with the advantages of round plant type, many and dense flowers, easy to plant with other flower bed plants, long ornamental period and so on. so it's becoming more and more popular. It is generally cultivated in spring and autumn. Perennial evergreen herbs, stems erect, slightly fleshy, 25cm ~ 40cm tall, with well-developed fibrous roots; leaves ovoid to broadly ovoid, base oblique, green or purplish red; monoecious, Cymes axillary, flowers in red, pink and white, single or double, many varieties. Flowers, the four seasons begonia beautiful, green leaves, delicate and beautiful flowers, widely loved by the public, potted viewing, has been for thousands of years. Put several cases in the cold season, the indoor is full of spring, spring and summer under the balcony eaves, more lively and lively. The morphological characteristics of Begonia are perennial herbs or woody plants. Crystal green leaves, delicate flowers, but gorgeous and not vulgar, gorgeous and dignified. Used to decorate the room, very fresh and elegant. If the hanging basin, wall hanging planting, hanging indoor, it will be interesting. The stem of begonia is green and the nodes are dilated and succulent. Some have roots and some have tubers. Leaves alternate, with round or different oblique center dirty shape on both sides, some leaves are similar to elephant ears, the leaves are pure green, red-green, purple-red, dark brown, or have white markings, red on the back, and some leaves have protuberances. Flowers terminal or axillary, Cymes, flowers with white, pink, red and other colors, flowering four seasons, but the spring and autumn seasons are the most popular. There are more than 400 species of begonia, and nearly a thousand horticultural varieties. It is divided into three categories: bulbous begonia, rhizomatous begonia and fibrous root begonia. The ecological habits of four seasons begonia like sunshine, slightly resistant to shade, afraid of cold, like warmth, slightly wet environment and humid soil, but afraid of heat and waterlogging, pay attention to shading, ventilation and drainage in summer. Sharing of planting and breeding experience: if you plant begonia like the above paragraph, you will have a high probability of failure. In fact, in the south of the Yangtze River, it is better to put outdoor extensive management, and it is all right to put it outside in summer. Just take a little shelter during the rainy season. The main thing is ventilation, which is very important. Watering in summer is better in the morning than in the evening. Watering can not be too dry, you can see that the surface is slightly dry and can be watered (the concept of micro-drying is that the wet soil is originally very black, but now it is a little yellow, not too black, it is not to say that the topsoil is dry and white, hope to understand), once thoroughly poured, hard watering, the bottom hole below the water, there is no water above. You'd better repeat the thoroughly watered water again. A total of two times of thoroughly watered water is basically foolproof. Of course, it should be frostproof in winter, just put it under the eaves to shelter from the cold wind. Classification of varieties of four Seasons Begonia the leaves of Begonia can be divided into two categories, one is red-green after receiving sunlight, and the other is red and copper. There are red, peach, white, complex color and so on. The flower shape is divided into double and single. Double petal varieties are not easy to collect seeds, and most of them are propagated by cutting nutrition. The commercial varieties are almost hybrid F1 varieties, and their properties are strong. The cultivation technique of four seasons begonia is the key to raise the water and fertilizer management of four seasons begonia. The requirement of watering work is "two more and two less", that is, spring and autumn are the periods of growth and flowering. The moisture should be more appropriate; the basin soil is slightly wetter; in summer and winter is the semi-dormancy or dormancy period of the four seasons begonia, the moisture can be less, the basin soil is slightly drier, especially in winter, and the basin soil should always be kept slightly dry. Watering time should also be noted in different seasons, watering in winter should be carried out in the sun around noon, and summer watering should be carried out in the morning or evening, so that the temperature difference between temperature and basin soil is small, which is beneficial to the growth of plants. The principle of watering is "do not dry, do not water, dry is thoroughly". During the growing period, Begonia should apply 20% fermented bean cake water, rapeseed cake water, chicken and pigeon dung water or human fecal and urine fertilizer every 10-15 days. When applying fertilizer, it is necessary to grasp the principle of "applying more thin fertilizer". If the fertilizer solution is too thick or unfermented raw fertilizer is applied, it will cause fertilizer damage, light leaves scorched, heavy plants withered. Spray water on the plant with a spray can after fertilization to prevent the fertilizer from sticking to the leaves and causing yellow leaves. When the growth is slow in summer and winter, less or no fertilization can avoid rot due to tender stems and leaves and weakening heat and cold resistance. Another characteristic of the conservation of begonia in the four seasons is to pick the heart. Like jasmine, rose and other flowers, when the flowers fade, they must be pruned and heart-picked in time in order to promote more branches and blossoms. If the work of coring and pruning is ignored, the plant is easy to grow long and thin, the plant shape is not very beautiful, and the flowering is less. After Qingming Festival, potted plants can be moved to outdoor shade for maintenance. East China should be maintained in full shade from April to October, but it is best to see a little sunlight in the morning and evening. If the leaves are found to be curled and scorched, this is a symptom of sunburn. After arriving at Frosts Descent, it is necessary to move into the indoor anti-freezing to keep warm, otherwise suffer frost, will freeze to death; indoor furnishings should be placed in the sunny place. If the room temperature lasts above 15 ℃ and topdressing is applied, it can still blossom. Light, water, temperature and heart picking are the key to growing begonia in four seasons. After planting, the four seasons begonia can be exposed to direct sunlight in early spring, and should be properly shaded with the increase of sunshine. At the same time, we should pay attention to the management of moisture, too much water is easy to produce rotten roots, rotten buds, rotten branches; high temperature and humidity are easy to produce various diseases, such as stem rot? After planting slow seedlings, apply liquid fertilizer every 10 days. Timely pruning long branches and old branches to promote new lateral branches, strengthening pruning is conducive to the beauty of plant shape. The soil conditions of cultivation require neutral or slightly acidic soil rich in humus and good drainage, which is afraid of both drought and water stains. With seed propagation as the main and cutting as the auxiliary. The seeds are small and can be spread on the plate first, germinated and then transferred to the hole plate, or directly seeded in the hole plate with powder seeds. The fertility is strong, it is not easy to get through under the high temperature in summer, and the rest of the year is good. Can be divided into green leaves and copper leaves, under sufficient light, green leaves in the leaf color performance is excellent. Cutting propagation was carried out from August to December. Cuttings in August can take root in about 20 days. After transplanting once, it was colonized about 40 days later. In general, thin liquid fertilizer is applied every 10 days, watering should be sufficient to keep the soil moist. If you want to make the plant clump larger, bloom luxuriantly, should pick the heart many times, generally leave two nodes, pick the new shoots, promote branches and blossom more. Potted plants in late June will begin to shade and avoid summer heat, and prevent stagnant water in the basin, otherwise perishable roots will die. Cultivation points 1. Sowing: the seeds of Begonia are very small and need to be operated by a special sowing bed, and the sowing medium is fine vermiculite or perlite. The suitable temperature for germination is about 15 ℃, and the suitable sowing time is March, April or October or November. High temperatures in summer are not easy to sprout. 2. Transplant into pot and plant: cuttings can be transplanted into small pots after rooting, and must be fully watered after transplantation. after 5-6 leaves, they can be put on the pot, and the distance between planting plants is about 18-20 cm. 3. 3-4 plants can be planted in the long flowerbed, and adequate water supply is needed in midsummer, otherwise the leaves are easy to wither, liquid fertilizer should be added during planting, and if the plant is too long and too large, it can be cut to about half in August. In the process of cultivation, the long branches of individual apprentices should be heart-picked to promote the side branches to blossom and keep a good plant shape. 4. Other management points for attention: (1) Begonia is not resistant to direct sunlight and rain in summer, so it should be shaded and rain-proof. If it is exposed to rain for a long time, it is easy to cause flower stem and leaf corruption. Winter likes plenty of sunshine, lack of light, then the growth is weak, the plant is slender, the leaf color and flower color become light, the light is too strong, the leaf shrinks, the scorch spot appears, and when the fertilizer is insufficient, the plant is short and the leaf is red. (2) Irrigation and drainage: potted begonia should be watered after the basin soil is dry. if the basin soil is kept moist for a long time, it is easy to cause root rot. (3) fertilization: the whisker root of Begonia in four seasons grows vigorously. During the growing period, attention should be paid to fertilization management, topdressing dilute liquid fertilizer once a week, and compound fertilizer 150-200ppm is suitable. Watering should be sufficient, after 2 years of cultivation, the growth of the general plant is gradually weak and the plant shape is irregular, that is, it needs to be replaced. In production, annual cultivation is usually done. But in horticulture, it can be used as perennial cultivation. Begonia is propagated by sowing or cutting. Four seasons begonia is easy to receive a large number of seeds, and the germination power is very strong, generally use seeds to propagate. Sow the seeds immediately after harvest, generally sowing in the shallow basin from August to September, pay attention to the fine topsoil, because the seeds are small and strong, do not sow too dense. Do not cover the soil after sowing, soak the basin soil, cover it with glass, place it in a semi-shaded place, keep it moist, and seedlings can emerge after a week. The propagation methods of four seasons begonia are mainly sowing, cutting and dividing plants. if commercial cultivation, sowing and propagation are adopted. The seeds of four seasons begonia are small and have a short life span. The seeds that naturally fall into the basin soil often germinate quickly and grow seedlings, but few seeds are harvested if they are not sown in time. Most of the cuttings are carried out from March to May or from September to October, using plain sandy soil as cutting substrate, or directly on plastic flowerpots, and the nodes need to be inserted into the soil. Under the condition of shade and heat preservation, it can be rooted in more than 20 days. Perennial old plants can split them and prune them at the same time to promote the development of new lateral branches to form an intact plant shape. [propagation method]: common sowing method and cutting method are used to propagate. [sowing method]: East China is generally the most suitable in April-May in spring and August-September in autumn. The seeds should be evenly removed and sown on the fine mud in the basin (no need to cover the soil). Then use the sowing pot to absorb enough water, then cover a piece of glass and put it in a half-shaded place, which can sprout after 10 days. The seedlings sown in spring can blossom in the autumn of that year. [cutting method]: it can be carried out all the year round, but there are few branches after seedling, except for double-petal varieties, this method is not generally used to propagate. (4) usage: the four seasons autumn crabapple has a long flowering period, many colors and rich changes. It is a kind of beautiful flower with beautiful flowers and leaves. It is not only suitable for outdoor cultivation such as gardens and flower beds, but also a good decoration for indoor family desks, coffee tables, desks and shop windows. ① fat. During the spring and autumn growth period, it is necessary to master the principle of applying thin fertilizer frequently, mainly applying rotten organic thin fertilizer water or inorganic fertilizer soaking solution without peculiar smell. More nitrogen fertilizer is applied in the seedling budding stage to promote the growth of branches and leaves; in the budding and flowering stage, more phosphate fertilizer is applied to promote the gestation of flower buds, flowers are many and bright, if lack of fertilizer, the plant will wither or even die. ② water. In the peak growth period of spring and autumn, the soil needs to contain more water, watering should be timely and keep moist. ③ summer overwintering management. Due to the influence of temperature in summer and winter, the growth is slow, so it is necessary to strengthen the management of fertilizer and water. In the high temperature season in midsummer, it is necessary to take measures to avoid strong direct light and cool down to create a small environment below 30 ℃, keeping the basin soil dry and wet, the roots are too wet and easy to rot, and the leaves will wilt if they are too dry, as long as they are slightly moist; if you apply too much fertilizer in this period, it will cause tender stems and leaves or rot disease. As long as the winter temperature is kept above 10 ℃, it can survive the winter safely. In summer and winter management, if the temperature can be controlled below 30 ℃, the temperature is above 10 ℃, the watering is dry and wet, and the fertilization is appropriate, the plant must be strong and blossom continuously in four seasons. Disease control and pest control of four seasons begonia: the main diseases are leaf spot disease and the harm of bacterial diseases. Topurazine, chlorothalonil and Jinggangmycin should be used to control them. Insect pests are mainly various pests that harm leaves and stems, such as slugs, thrips, leaf miners and so on. The main results are as follows: (1) the common diseases are powdery mildew, bacterial blight, aphids, powdery shells, red spiders and so on. Prevention and control methods, to environmental control: high temperature and humidity is conducive to the reproduction of bacteria, so close planting should be avoided in cultivation to facilitate ventilation. When planting in greenhouse, if the temperature difference between day and night is large, you should avoid watering in the evening so as not to drop the temperature at night, resulting in excessive humidity and even water vapor condensation. (2) keep the cultivation place clean: if there are infected plants and leaves, they should be removed and destroyed immediately. Avoid wetting the leaves when watering. Blight and blight is one of the common diseases of begonia in four seasons, which occurs in flower field and family potted begonia. It mainly harms the leaves at the base of the stem and near the soil surface. In the early stage of the disease, the base of the stem near the soil was infected with dark spots, which became brown and rotten after expansion. The leaves are infected with dark green waterlogging-like round spots and brown rot when infecting the petiole. In the morning with high humidity, it can be seen that the disease spot has white to light brown filaments. Seriously diseased plants lodge or rot and die. The pathogen overwinters with mycelium or sclerotia in the diseased tissue or in the soil. When Begonia is divided or propagated by cuttings, the wound is caused by the temperature of 20-24 ℃, high humidity or excessive watering in overcast and rainy weather, the pathogen invades and often causes the disease to occur seriously. Prevention and treatment methods (1) timely removal of diseased leaves to strengthen ventilation. (2) soilless cultivation was adopted. Compost made by retting with enzyme bacteria is recommended for soil cultivation. Select new soil rich in organic matter or pond mud, river mud and so on to prepare basin soil. (3) disinfect the soil conditionally, use 40% pentachlorothiram or seed-mixed double powder, the dosage is 8g per cup, mix well with the soil and put it into a basin and set aside. (4) at the initial stage of the disease, 95% Luheng No. 1 was sprayed with 3000 times liquid or 20% methyl rifampicin EC 1200 times, 50% Likuling wettable powder 1000 times, potassium permanganate 1200 times. (5) after the onset of the disease, 40% pentachlorothiram or seed dressing powder plus fine sand can also be used to form a drug soil of 200 times, with 100g / 150g per plant or pot, once every 10 to 15 days. (6) the spread of Trichoderma harzianum can be effectively controlled by using cultured Trichoderma harzianum 0.4~0.45kg, adding 50kg fine soil, mixing and sprinkling on the base of the diseased plant. Begonia is sensitive to fungicides, some new varieties need to be tried before large-scale application of the four seasons crabapple dietotherapy or medicinal value of the medical information and health dietotherapy information is only for reference, can not be used as a basis for diagnosis and medical treatment. Any health problems should consult professional health care personnel, the treatment of any disease, please follow the doctor's advice. The ultimate task of protecting flowers: to love yourself, proceed from reality and follow the doctor's advice. For disease, do not be careless, do not postpone, do not give up hope, face it bravely, warm the silent world with love, and protect the inner flower field with your heart. Four seasons begonia beautiful, green leaves, delicate flowers, widely loved by the public, potted viewing, has been for thousands of years. Put several cases in the cold season, the indoor is full of spring, spring and summer under the balcony eaves, more lively and lively. Begonia is widely used in the world. In addition to potted ornamental plants, it is also a material for flower beds, hanging pots, planting grooves, window boxes and indoor layout. There has been a rapid development in the quantity and quality of use, among which in the United States, in addition to pot ornamental, it is more used for flower bed appreciation, and many new varieties with strong adaptability, heat resistance and moisture resistance have been selected. Denmark, Sweden, Norway and other countries in northern Europe mainly produce high-quality potted ornamental species and export to Western European countries. Among them, Dane Feldt of Denmark is famous for producing begonia in four seasons. Countries such as the Netherlands, Britain and France also have a certain amount of production. In short, the four seasons begonia is still quite popular in the European market. Japan has a certain amount of production, mainly to meet the needs of the domestic market. Seeds are imported from the United States and Denmark. The cultivation of Begonia in China began in 1912, was introduced from the United States in the 1930s, and was cultivated in Shanghai and Nanjing. Large-scale production only began in the 1990s. Up to now, the demand is increasing year by year, which can meet the needs of the current market at a low level, and seeds rely on imports. Four Seasons Begonia flower language: Acacia, care, sincerity, unrequited love, bitter love. Begonia: Acacia, heartbroken flower, August spring. According to history, when Lu you and Tang Wan had no choice but to part, Tang Wan gave Lu you a pot of begonia as something to miss. When Lu you asked Tang Wan, "what kind of flower is this?" Tang Wan replied sadly, "this is heartbroken red." Seeing this, Lu you had a lot of thoughts and casually said, "it should be called Acacia Hong." Since then, begonia has been handed down in the world with the name of "Acacia Hong". Begonia symbolizes bitter love. When people encounter twists and turns in love, they often describe themselves as begonia flowers and call them heartbroken flowers to express the sad feelings of parting between men and women. There will be "bitter love" in the language of flowers. Take care of, like this flower you, give people a kind of loving and friendly feeling, you always have a gentle tone to people, lovers in your hug completely feel protected and spoiled, always slow to do things, will never act in a moment of pleasure. Flower motto: self-confidence is the first condition for success, believe that you can break through the difficulties. Characteristics and Propagation methods of four Seasons Begonia

One of the more common varieties of begonia is the four seasons begonia, which is often used as bonsai for indoor and outdoor decoration. Because of its beautiful body, flowers in clusters can bloom in four seasons, so it is loved by the public.

In short, the four seasons begonia is still quite popular in the European market. Japan has a certain amount of production, mainly to meet the needs of the domestic market. Seeds are imported from the United States and Denmark.

The cultivation of Begonia in China began in 1912, was introduced from the United States in the 1930s, and was cultivated in Shanghai and Nanjing. Large-scale production only began in the 1990s. Up to now, the demand is increasing year by year, which can meet the needs of the current market at a low level, and seeds rely on imports.

[morphological characteristics and varieties] Begonia is a perennial herb. Stem erect, much branched, fleshy, bald and smooth. Leaves alternate, glossy, ovate, margin serrate, green or reddish. Flowers reddish, axillary, several in clusters. There are many cultivated varieties, with tall and dwarf plant types, single and double flowers, and red, white and pink flowers. The leaves are green, purplish red and dark brown. The common variety is Ambassador of green leaf line, with a plant height of 20cm to 25cm and strong branching. Olympic (Olympia), flowers are pink, red, orange-red, white, mixed colors and other colors. Lotto, plant height 10 cm. Huamei (Pizzazz), with a height of 20cm to 25cm. Victory, the height of the plant is 20cm to 25cm. Linda (Linda), plant height 15-20 cm. In addition, there are large flowers, green leaves of emerald and large flowers and green leaves, heat-resistant, rain-resistant prelude. Copper leaf cocktail (Cocktail) series, sun-resistant, not afraid of the sun, there are pink brandy (Brandy), rose red gin (Gin). Pure white whiskey (Whiskey), bright red vodka (Vodka), white rum with rose rim (Rum). Party (Party), large flowers, flower diameter 5 cm, good branching, plant height 30 cm. Rio, with a height of 20cm to 25cm, is the darkest series of copper leaves. It has strong adaptability and is suitable for outdoor cultivation. The senator (Senator) is highly branched. Angel, plant height 20-25 ℃, early species, multi-flowering series, wide adaptability.

[biological characteristics] Begonia is native to South America and Brazil. Like warm, moist and sunny environment. The suitable temperature for growth is 18-20 ℃. The temperature in winter is not lower than 5 ℃, otherwise it grows slowly and is vulnerable to freezing damage. When the summer temperature exceeds 32 ℃, the growth of stems and leaves is poor. But the series of heat-resistant varieties such as prelude, cocktail and Angel can still grow normally under high temperature.

The branches and leaves of Begonia are tender and succulent, the water content is higher, and the growing period has higher requirements for water. In addition to watering, it is very necessary to increase air humidity through leaf spraying. However, the stagnant water in the basin or the air is too dry, which is also very disadvantageous to the growth and development of Begonia. Especially in the seedling stage, it is easy to cause seedling rot and disease and insect damage.

Begonia in four seasons has strong adaptability to light. It can grow not only in semi-overcast environment, but also in full light, with neat flowering and bright colors. The green leaves grow under strong light, the edges of the leaves are easy to turn red and the leaves are tight, while the copper leaves are thicker and glossy.

Potted begonia is suitable to use fertile, loose and well-drained rotten leaf soil or peat soil, pH5.5~6.5 slightly acidic soil.

[propagation methods] sowing, cutting, ramet and tissue culture are commonly used.

Sowing and reproduction: it is suitable for spring and autumn. The seeds are small, about 70000 seeds per gram, short-lived, and the seed germination rate decreases significantly in the next year. The suitable temperature for germination is 20: 22 ℃. After sowing, it is not covered with soil, and it can be flattened after sowing. It germinates in about 7-10 days. It sows in autumn, overwinters in greenhouse and blossoms in the next spring. It usually blossoms 130-150 days after sowing.

Cutting propagation is the best in spring and autumn, cutting 10 cm tip shoots as cuttings, cutting soil with fine sand or expanded perlite, half of cuttings are inserted into soil, keeping high air humidity and room temperature at 20: 22 ℃, rooting at 16: 20 days after cutting. If treated with 0.005% indole butyric acid for 2 seconds, the rooting of cuttings could be promoted.

Ramet propagation: when changing pots in spring, the mother plant is cut open, potted directly, and maintained and restored in a semi-shady place.

Tissue culture propagation: explants with tender stems, first gently scrubbed with clean water, sterilized in the sterile room with 70% alcohol for 30 seconds, then soaked in 5% 10% bleach solution for 10 minutes, and finally washed with aseptic water for 4 times. Explants were inoculated on MS medium supplemented with 0.5mg / L 6-benzylaminoadenine and 0.1mg / L naphthylacetic acid to promote the production of adventitious buds. Then the 1/2MS medium was added with indole acetic acid 0.2mg / L to promote the differentiation of adventitious roots and become complete plants. It takes 4 months from explant inoculation to complete plantlet production.

[cultivation management] the root system of Begonia is well developed and grows fast. It needs to change pots every spring and add fertile and loose rotten leaf soil. Keep the basin soil moist during the growing period and apply fertilizer once a month. During the period of flower bud formation, the phosphorus and potassium fertilizer was applied for 1 / 2 times. Or use 20Mel 20Mel 20 general purpose fertilizer, soilless cultivation for a long time use 15Mel 15Mel 18 soilless cultivation fertilizer. It needs an adaptation process to transfer from weak light area to strong light area at seedling stage or flowering stage, otherwise the leaves are easy to curl and focal spots appear. On the contrary, the light is insufficient, the design and color appears dim, lack of luster, and the stems and leaves are easy to grow and weak.

The four Seasons Begonia often uses 10 cm pots. When the seedling is 10 cm high, it should top and pick the heart, depress the plant type, and promote the germination of new branches. At the same time, 10-15 days after coring, spraying 0.05%~0.1%B9 for about 2-15 times could control the plant height at 10-15 cm. The four seasons begonia is generally cultivated for biennial cultivation. It needs to be updated after 2 years.

[pest control] common leaf spot and powdery mildew hazards are sprayed with 75% chlorothalonil wettable powder 800 times. Thrips, pink scale and leaf roll moth are harmful to stems and leaves, which can be sprayed with 1500 times of fenitrothion EC.

[post-natal treatment] the four seasons begonia has a round plant with many and dense flowers, which is very suitable for small potted plants, decorating family desks, coffee tables, desk and shop windows, conference bar tables and restaurant tables, with luxuriant branches and delicate colors. Such as the layout of the city's central square, flower beds, flower beds, constitute scenic spots, flowers like brocade, eye-catching. If processed into three-dimensional styles, umbrellas and hanging pots, colorful and unusual.
