Usually, begonia needs cutting to raise seedlings. Cutting time can be carried out except in severe winter, and May is the best. Cutting should take the top of healthy shoots with 2 or 3 buds, cut to 0.5 cm below the node, and remove the lower leaves. If the upper leaves are too big, you can cut off 1/2. Then, the cutting depth is 65438+ 0/3 of the cutting length. Pay attention to the shade and humidity after cutting. At the temperature of 22℃, it can take root in 3 weeks, and can be potted after 1 month. You can also insert the selected branches into water, soak them in water, change the fresh water every 1 ~ 2 days, and transplant after rooting. It takes about four to five months from cutting to flowering.
Daily management requires care.
Begonia japonica has strong adaptability and can grow in neutral and slightly acidic soil, especially in loose and fertile slightly acidic sandy soil rich in humus. Begonia japonica is afraid of cold and heat, and the optimum growth temperature is 18℃-2 1℃. Summer management is particularly important: 1, avoiding strong light. At high temperature, if the light is too strong, it is easy to cause the leaves to be dry and sharp, turn yellow or even fall off. Therefore, it is best to put it under the ventilated scaffolding or corridor in the yard in summer to receive more scattered light. 2. Avoid light. Begonia likes scattering light, but it is afraid of the dark. If it is placed in a dark place in summer, it will not only reduce the number of leaves and flowers, but also cause plants to grow in vain. If it is placed in too dark place for a long time, it will also cause yellow leaves to fall off and even plant death. 3, avoid being dry and afraid of being wet. During the peak growth period in summer, keep the soil moist but not too wet to avoid water accumulation in the basin. If the weather is too dry and hot, in addition to watering the pot soil, you should also spray water on the leaves and ground around the flowerpot 2 ~ 3 times a day, which is beneficial to its growth and flowering. 4. Appropriate fertilization. In the growing season, it is necessary to apply 1 times of organic fertilizer solution in about half a month; During pregnancy, more phosphorus and potassium fertilizers should be applied to promote flowers to flourish, and less or no fertilization should be applied during flowering. 5. In addition, attention should also be paid to pest control, pruning and shaping, so as to promote more new branches, more pregnant buds and more flowers, and maintain its beautiful plant type.
In the process of cultivating begonia, it will be found that the leaf edge of begonia is scorched and falls off. The main causes of leaf edge scorching and defoliation of Japanese begonia are:
Low temperature or hot summer. Begonia likes warmth, and the most suitable temperature for growth is 18℃-2 1℃. Although it is a relatively cold-resistant begonia variety, its leaves are easy to crack and fall off under 5℃. Begonia is afraid of hot summer, the temperature is above 30℃, the plant grows slowly, and it is in a semi-dormant state. If it is not properly maintained, it is easy to produce leaves.
Strong light or cloudy day. Begonia likes enough scattered light. In summer, when the temperature is high, the light is too strong, which is easy to cause the focal tip and edge of leaves, and the leaves turn yellow or even fall off. If there is insufficient light, the number of leaves and flowers will decrease, and plants will grow in vain. If the light is too weak, the leaves will fall.
Drought or excessive humidity. Begonia naturally grows in forests or valleys with high humidity, and its stems and leaves are tender and juicy. Therefore, in addition to providing a humid ecological environment, we should also supply enough water during the growing period, but we should avoid being too humid. Excessive drought and humidity will affect the absorption of plant roots and cause defoliation, especially when the temperature is low in winter, otherwise it will easily lead to root rot and defoliation.
I believe that under the guidance of scientific methods, everyone can grow beautiful flowers.
Question 2: How to raise begonia? The environment is dry, so it is necessary to spray water on the leaves frequently. If the soil is alkaline, the flowers should be watered with fermented rice.
It is very resistant to pruning. I suggest you cut it 20-25 cm from the soil surface and regrow the bottom buds.
Cut the 20 cm part and cut it with plain soil.
Peacetime maintenance
Cutting propagation can be carried out all year round. You can also insert leaves, but it is difficult to produce adventitious buds. The flowerpots need to be replaced and trimmed every spring.
Attention should be paid to during maintenance:
1. Begonia argentea is not clustered, so it needs to be picked in order to increase branches. At the same time, when the pots are turned over every spring, the plants are pruned vigorously, and only 2~3 buds are left at the base of each branch to promote the germination of new branches.
② Fertilize and water. Pot soil should be fertile, well drained, neutral or slightly acidic culture soil. In order to facilitate drainage, the original hole at the bottom of the basin should be chiseled and applied with base fertilizer. Keep the soil moist during the growing period, apply 1 time of light liquid fertilizer every two weeks, and stop applying fertilizer in summer and winter. Water should be sprayed on the leaves and the ground at ordinary times to increase the humidity of the environment.
(3) light and temperature. The temperature cannot exceed 30℃ in summer. Avoid direct sunlight, so take cooling measures such as shading and spraying water; In winter, the temperature should not be lower than 10℃, so it needs to be cultivated under the conditions of scattered light and good ventilation.
Question 3: Matters needing attention in winter cultivation of begonia.
Key points of cultivation of begonia nodosa
1, temperature: I like warmth, and the most suitable temperature for growth is 18-20 degrees. Begonia is a cold-resistant variety, but it still needs a temperature above 5℃ to overwinter. When the temperature is lower than 5℃, the leaves will fall off. When the temperature is 2℃, a large number of leaves will fall off and the branches will turn yellow and die, but the plants can still germinate and sprout in the remaining cold and die in the next spring. Afraid of summer heat, the temperature reaches above 30℃, and the plants grow slowly and are in a semi-dormant state. Improper maintenance is easy to produce fallen leaves, so measures such as shading, spraying water on leaves and strengthening ventilation should be taken to reduce the temperature and form a relatively cool small environment.
2. Lighting: I like enough scattered light. When the light is suitable, the stems are thick, the internodes are short, there are many lateral branches, the leaves are bright and the colors are bright. Avoid strong sunlight. When the sunlight is too strong, the leaves will turn yellow, scorch the edges and even fall leaves. It can't be cloudy, otherwise the plants will grow tall and thin in vain, and the flowers will be scarce or even not flowering, which will cause defoliation in severe cases. Shading should be done from May to September, or plants should be placed in places with sufficient scattered light. At other times, it is necessary to give enough sunshine, and it is easy to form flower buds in spring and autumn.
3. Watering: For the soil environment that is afraid of drought and likes humidity, it should be fully watered during the growing period to keep the basin soil moist, not too dry or too wet. Too dry and too wet will affect the absorption of roots, resulting in defoliation, germination and flowering. Avoid excessive humidity and water accumulation, otherwise the roots will rot and die. Although plants are in a semi-dormant state under high temperature in summer, due to the high temperature and large leaf area, it is still necessary to master the principle of "no watering, no watering, thorough watering", but to prevent wet waterlogging. Control the water in winter and keep the basin slightly dry. Too much watering can easily cause rotten roots and fallen leaves. .
4. Environmental humidity: the original habitat is under the forest or beside the ditch with high humidity, so the relative humidity of the air should be not less than 500o, preferably 65%-70%. When it is too dry, the edges of the leaves will roll up, turn brown or even wither. During the growth period, water should be sprayed on the branches and leaves and the surrounding areas to improve the relative humidity of the air. Spraying foliar water in summer can also reduce the temperature, which is beneficial to the growth and flowering of plants.
5. Fertilization: from April to June, topdressing is performed for l times every 10- 15 days. In the first half of April, nitrogen fertilizer should be mainly used to promote the growth of branches and leaves, and phosphorus and potassium fertilizer should be applied in bud stage to promote pregnancy and flowering in bud stage. Fertilization should be stopped during flowering. Because the root system is many and small, it is sensitive to the concentration of fertilizer, so we should pay attention to "thin fertilizer and diligent application" to avoid the high concentration of fertilizer solution. Don't pollute the leaves with fertilizer solution when applying fertilizer, otherwise it will burn the leaves. Stop fertilizing when it is in semi-dormancy state in summer. Autumn is also a vigorous growth period, and topdressing 10- 15 days, but after 1 0 months, stop applying nitrogen fertilizer and topdressing phosphorus and potassium fertilizer twice to improve the cold resistance of plants. Stop fertilizing when the temperature is lower than 10℃ in winter.
6. Pruning: coring should be carried out at seedling stage to promote branching and form a plump plant shape. In spring, plants should be pruned in combination with turning pots. If the plant is too high, which affects the appearance of the plant, the branches that are too high can be cut short and cut hard to promote new branches and control the plant height. Strong germination, because the inflorescence is born on the new branch. When the new branch grows to an appropriate height, it is necessary to cut off the old branch to promote plant regeneration and facilitate future flowering. If the plant is tall and has many inflorescences, a bracket should be set to prevent the branches from bending under heavy pressure. After the flowers wither, the residual flowers and flowering branches should be cut off immediately to promote the development of new branches, so that they can bear more buds and bloom frequently.
7. Turn over the pot: l Turn over the pot once a year, after warm spring or in September. I like the slightly acidic sandy loam which is rich in organic matter, loose and well drained. The substrate can be humus soil, peat soil, garden soil, potato bran ash or perlite.
8. Pest control: there are powdery mildew, damping-off disease, thrips, red spiders and other pests and diseases.
Question 4: How to raise begonia, its cultivation methods and matters needing attention. Introduction of cultivation techniques Morphological characteristics: It belongs to perennial herbaceous plants in autumn sea. Leaves alternate. triangular
Shaped or obliquely heart-shaped, with wavy serrations on the leaf margin and wedge-shaped tomb. The leaves are steel green with silvery white spots, the back leaves and heart leaves are reddish brown, the stems are green, the nodes are short and round, the flowers are red, they are axillary, and they bloom in autumn, winter and three seasons. Beautiful flowers and leaves. Tt has a long flowering period and high ornamental value. It is an ideal flower for flower bed beautification and indoor viewing.
2. Growth habit: Sexual preference for warm and humid climate. It is shade-tolerant, adapts to sunlight by about 50%-70%, and likes direct sunlight and soft sunshine in winter solstice and spring. I like loose and fertile sandy soil rich in humus. I avoid high temperature and humidity, and the suitable growth temperature is' 5-25O:
3. Types and varieties: Begonia bambusa and Begonia Tokyo.
4. Propagation method: Cutting is often used, and spring and autumn are suitable cutting periods. Select the terminal bud with strong growth, about 5- 17 stems, remove the lower leaves, leave 2 1-4 leaves on the upper part, and cut in half. Cut it into Zusha or perlite, keep the soil humidity 30%-40% and the air humidity 70%-85%, take root in 50%-70% light for about 20 days, and transplant it after the root group grows vigorously. Potted plants can also be planted directly in pots and forced to fertilize after taking root.
Question 5: Regarding the cultivation method of potted begonia with bamboo leaves, begonia is a shallow-rooted plant, which likes semi-shade, moist and warm, is not cold-resistant, and avoids sunlight, high temperature and waterlogging. The suitable growth temperature is 65438 05℃ to 25℃. Strong drought resistance, afraid of stagnant water, like loose and fertile sandy loam. The principle of watering is to see dry and wet. Fertilizer is the basic element of plant growth. Fertilization should be carried out when the basin soil is dry, and watering after fertilization is beneficial to plant absorption. When the stems and leaves are not prosperous or the pots are newly turned over, it is forbidden to apply large fertilizers. During the vigorous growth period in spring, dilute liquid fertilizer should be applied every 10 day to15 day. In the hot summer season, plants stop growing and fertilization should be reduced. Fertilization is suspended in flowering and winter. Strengthen the light time, begonia likes shade and is afraid of exposure, which is suitable for perennial cultivation in Nanyang Terrace. Sufficient sunshine should be given in spring, autumn and winter. Avoid strong light in summer, otherwise the leaves will turn yellow and grow slowly. Strengthening plant pruning is conducive to maintaining a good plant shape. For those who have grown for many years, or the plants grow too high, or the leaves at the lower part of the stem fall off, which leads to the unsightly plants and affects the ornamental effect, pruning combined with changing pots in spring can help the plants grow new branches and open more colorful flowers. Pest control should fully implement the policy of giving priority to prevention and comprehensive management. In case of hot and humid weather, begonia is prone to pests and diseases. For the prevention and control of pests and diseases, we must first strengthen ventilation and light transmission, and the soil in the basin should not be wet, let alone let water accumulate in the basin. The second is to spray fungicides, such as thiophanate methyl and carbendazim, once every half month to prevent diseases. If the harm of red spider is found, dicofol 1500 times can be sprayed.
Question 6: How do begonias breed? Begonia flowers like light and drought tolerance, water in time when drought occurs, and like fat water. It is best to add some nutrient solution when watering and put it in a bright place indoors. It is better to go to the flower shop to buy a bottle of plant growth nutrient solution. It's best to add some nutrient solution every time you water it, so that the plants grow better and brighter, and the colors are brighter.
Question 7: Is Begonia Bamboo Leaves Suitable for Indoor Culture? It is a flower of Begonia bambusa, which is suitable for indoor cultivation and the whole plant is non-toxic.
Question 8: Is it ok to keep begonia in the bedroom?
Function and efficacy of begonia
In Qing Dynasty, Yuan Mei wrote about Haitang, saying, "Little flowers are delicate and graceful, but it is autumn, and bloom is late. You are not ignorant. " Begonia, also known as August spring and heartbroken soup, is a perennial herb of Tangqiu family. Originated in China. It has many varieties, such as four-season begonia, bamboo begonia, spotted begonia, hairy begonia and ginkgo begonia. Below, Hua Mu, China. Com introduces you to the efficacy and function of begonia:
Function and efficacy of begonia
The whole grass of Begonia contains oxalic acid. Its flowers are sour, cold and non-toxic. "Herb Mirror" says: "Wipe ringworm to kill insects."
Begonia root is also known as one mouthful blood, golden thread hanging gourd, red and white pill and Dahongpao. Flat and sour. Functions: promoting blood circulation, eliminating addiction, stopping bleeding and clearing heat. Treat traumatic injury, hematemesis, hemoptysis, dysentery, irregular menstruation, metrorrhagia, stranguria, sore throat. The stem and leaf functions of Begonia clear away heat and reduce swelling. Treat sore throat, carbuncle and traumatic injury.
Common prescriptions:
First, the treatment of traumatic injury: ① 3 grams of begonia root, ground into fine powder, swallowed with wine. 2 Haitang fresh whole grass, mashed with sweet wine, applied to the affected area.
Second, the treatment of metrorrhagia: 6 grams of begonia root, 6 grams of Eupatorium adenophorum. Decoct with water.
Third, the treatment of turbidity: white turbidity is ground with white sea roots, 3 grams each time, and boiled water is taken. Hematuria is ground with red begonia root tuber, 6 grams each time, and taken with boiling water.
Fourth, the treatment of tinea: Begonia flowers outside.
Question 9: How to raise begonia can prolong the flowering period, bloom more and last longer. When changing water every day, you can add 2% sugar water and aspirin to the water, which can prolong the flowering period.
Question 10: How to cultivate begonia? Is there any way to buy a pot with soil in it? The soil should be fatter and put on the windowsill. Water it more a few days ago (that is, watch it dry). Don't always look at it after you are alive. Put it outdoors. If it does not rain, water it once a week. If it rains, it doesn't matter. After a while, it will grow new branches and buds. If you drink milk, yogurt or something, pour the water for washing the bottle to it, which is when the nutrition in its soil is gone in the future.
Raising flowers is as arrogant as raising children!
