When does Rieger Begonia blossom and what are the propagation methods?

Rieger Begonia is a very good name, and it is a very suitable ornamental plant, so find out when Rieger Begonia blossoms and what are the methods of reproduction?

When does Rieger Begonia blossom:

The flowering period of Rieger Begonia is very long, from April to December, in which April to June and September to December are the blooming periods of Rieger Begonia, and the flowers are in full bloom. After the full bloom in June, it is necessary to accumulate nutrients in autumn before Rieger Begonia blossoms again in winter.

Begonia is known as Guoyan, and Rieger Begonia gives full play to this glamour. Rieger crabapple always has beautiful flowers, mostly double, with red, yellow, orange, white and other colors, gorgeous.

Rieger Begonia has unique flower posture, fragrance and color.

Notes on flowering of Rieger Begonia

If you want Rieger Begonia to blossom better, you must pay attention to a lot of details during flowering.

It is best not to fertilize the flowering stage of Rieger Begonia, and do not move the flowerpot casually, otherwise the flower bud will fall. Watering should be moderate, not too much water, so as to avoid stagnant water in the flowerpot and poor drainage of the soil. When watering, the water temperature needs to be close to room temperature. The suitable temperature for the growth of Rieger Begonia is 15 ℃ ~ 22 ℃, and the temperature during flowering should be kept between 15 ℃ ~ 17 ℃. When the temperature increases gradually after May, Rieger Begonia will enter a semi-dormant state, so it is necessary to reduce watering and stop fertilization.

In winter, Rieger crabapple will still blossom, so to maintain the appropriate temperature, Rieger crabapple needs to be placed indoors in the sunny place for maintenance, south-facing windowsill is a good choice. In summer, the sun is strong, need to give Rieger crabapple a little shade, it can grow well, but if the shade is too much, it will make the plant grow too much and affect the flowering.

In addition, when Rieger begonia blossoms, it needs to cut off the withered branches and residual flowers.

What are the breeding methods of Rieger Begonia:

1. The method of sowing and breeding of Rieger Begonia

Sowing and reproduction is a common method of plant reproduction, and Rieger begonia can also be sown. However, because the seeds of Rieger Begonia are relatively small, it is necessary to adopt a special method-small seed sowing method when sowing. When sowing Rieger crabapple, the sowing substrate can be made by mixing vermiculite powder and peat soil. Stir the substrate evenly, put it in the seedling pot and pour it thoroughly.

Sow the seeds of Rieger Begonia on the substrate, one by one, without covering the soil, wrap the seedling pot with transparent plastic film, keep the temperature at about 20 degrees, and the seedlings can emerge in 2 weeks. As the seedlings grow, slowly grow leaves, but do not remove the plastic film.

After the Beginning of Autumn, the plastic film can be removed and put on the basin in early winter. Watering is controlled before potting, and ventilation needs to be maintained after potting. With the growth of the plant, a larger pot can be changed.

2. The cutting propagation of Rieger Begonia.

The cutting propagation of Rieger Begonia is mainly branch cutting method and leaf cutting method.

The substrate of cutting is mainly vermiculite or clean sandy soil, and the substrate needs to be sterilized before use. If the branch is inserted, choose the appropriate branch, the length should be moderate and it should be pruned. If the leaf is inserted, you need to choose the leaf that is growing vigorously and take it off and set aside.

Insert the cuttings into the substrate, water them thoroughly, cover them with plastic film and place them in a cool and ventilated place. It will take about three weeks to take root. Let it grow for a period of time in the unearthed transplant.

3. Tissue culture of Rieger Begonia.

The method of tissue culture is to cultivate the seedlings of Rieger Begonia in the culture medium, which is characterized by mass production, but for flower friends, tissue culture is difficult and is not commonly used.

All right, guys, as you all know, Rieger Begonia has a long flowering period.

Breeding method of Rieger Begonia propagation method of Rieger begonia

Rieger Begonia has a long flowering period, emerald green leaves and diverse flower shapes, so it has a unique ornamental value, so many flower friends are often used to decorate living rooms, balconies and other areas. Next, I would like to introduce the breeding methods and breeding methods of Rieger Begonia.

Culture method of Rieger Begonia

1. Reproduction:

Cutting propagation is the first choice for family planting. Cut the top branch of 8 cm in length and insert it into a fine sand basin, cover it with glass sheet or plastic film, keep the sand moist, and place it in a semi-shade environment. Under the condition of 20 ℃ and 25 cm, it can take about two weeks to take root. When the root turns yellowish brown, it can be planted in the pot.

2. Temperature:

The optimum temperature for growth and development of Rieger Begonia is 18-22 ℃. The focus of family care is to keep warm in winter, and the minimum temperature should not be lower than 15 ℃. As the winter Rieger crabapple is still in the growth and flowering period, it should be placed indoors facing south and sunny places, such as indoor windowsill and so on. But be careful not to get too close to the heater, so as not to burn the branches and leaves, and when there is a high temperature lasting more than 28 ℃ in summer, cooling measures should be taken, such as putting it in an air-conditioned room or shading at noon.

3. Fat and water:

Rieger crabapple growth period requires sufficient fertilizer and water, during the growth period, thin fertilizer water should be applied every two weeks, such as bean cake, sesame sauce dregs soaking solution (concentration is 20%), soybean soaking solution or fermented rice washing water. Rieger crabapple pot soil requirements "see dry see wet", flowering period can not be too much watering, otherwise easy to fall flowers.

In addition, watering after drying water, can not directly use tap water to water flowers, the temperature of the water is low, after watering flowers easy to damage the root system, it is best to use the same water as room temperature. When raising Rieger crabapple in the family, we should pay attention to indoor ventilation, otherwise the leaves are prone to downy mildew and the leaf color turns yellow. On weekdays, it is best to spray water on the leaves once a day to remove dust in order to facilitate photosynthesis and promote the healthy growth of plants. Rieger Begonia is mainly sowing and cutting propagation, and tissue culture can also be used to rapidly raise seedlings.

4. Integer pruning:

During the growth period, coring should be carried out to promote the plant to germinate lateral branches in order to achieve plump plant type, and the excess buds should be removed in time, so as not to cause a large amount of nutrient consumption and affect the development of other flowers.

5. Pest control:

There are fewer diseases and insect pests in family cultivation of Rieger Begonia. Regular spraying of fungicides to prevent bacterial soft rot and powdery mildew can be sprayed with 1000 times of agricultural streptomycin 200ug/g. In order to prevent pesticides from polluting the air, some soil pesticides can be made, and the control effect is better.

The main results are as follows: (1) Ginger juice squeezed with water and sprayed at the ratio of 1:25 can prevent soft rot and other pathogenic spore germination.

(2) 50 grams of dried pepper, 50 times of water, boiling for half an hour, and spraying leaf surface with supernatant can effectively control aphids and red spiders.

Propagation method of Rieger Begonia

1. Sowing method

Because the seeds of Rieger Begonia are very small, the small seed sowing method must be used. The seeds of Rieger Begonia are basically imported, sub-coated and uncoated. Because the coated seed can be sorted, the hole seedling plate can be used, and the uncoated seed can only be used in the seedling tray. The sowing medium is peat soil and vermiculite powder, crushed and sterilized, then mixed and stirred, ready for use in a semi-wet state. Because peat soil is water repellent in dry state and cannot be watered, it can not be used in dry state. When sowing, first put the substrate on the nursery plate, and then pour water through the spray pot.

The coated seeds can be sorted with tweezers, one for each hole, and the uncoated seeds can be mixed with appropriate amount of fine vermiculite powder and sowed in the seedling plate. After sowing, there is no need to cover the soil, just spray with a fine spray can, and then wrap the seedling tray with transparent plastic film. When the ambient temperature was about 20 ℃, seedlings began to emerge in 12 days. When the seedlings grow out of true leaves, they can be properly ventilated to promote their roots. The little girl grows very slowly in three months.

The seedlings sown in early summer do not have to remove the plastic film throughout the summer, and the seedlings are resistant to high humidity and high temperature. After the beginning of autumn, the weather is cool, but gradually take off the plastic film to refine seedlings, to the early winter can be on the pot. To use a smaller flowerpot with porous bottom, the culture soil can be mixed with 2 parts of peat soil and 1 part of vermiculite powder (or 1 part of plain sand). Watering is controlled before the pot, so that the culture soil in the seedling tray is in a semi-dry state. to avoid root damage due to non-fragmentation of seedlings. Just on the pot of seedlings to prevent weather changes in the temperature is too high, at the same time to use plastic film cover, but not too tight, should be properly ventilated to prevent rotten seedlings. Under family conditions, it can not grow into a large plant, but flowers can be seen. It can only be cultivated into a large plant every other year, and a larger flowerpot can be replaced.

two。 Cutting method

At the end of autumn and the beginning of winter, the cut new branches can be used as cuttings when pruning and shaping the plants. Rieger begonia can be cut into branches or leaves. When inserting a branch, the length of the branch should be moderate, and the lower part of the branch should be cut into a horseshoe shape with a blade; when inserting leaves, six mature leaves with exuberant growth should be selected, and the lower end of the petiole should be obliquely cut with a blade. The cutting substrate is vermiculite powder or plain sand, and the contaminated substrate should be disinfected and reused. Water should be thoroughly watered after inserting the cuttings, but there should be no stagnant water on the leaves. And use plastic film to cover it, put it in the place of scattered light, properly ventilate and avoid high temperature. The cuttings can take root in about 3 weeks. When a new leaf is seen to grow, it shows that it has taken root. The plant obtained by branch cutting method has no underground tuber. After 3 weeks of leaf insertion, fibrous roots can also grow in the lower part of the petiole, but it will take another month and a half to grow adventitious buds from the petiole and gradually unearthed.

3. Tissue culture method

Tissue culture is a method to quickly obtain a large number of flower seedlings. In the growing season, a large number of virus-free seedlings can be obtained by non-toxic explant culture, subculture and rooting culture in a certain medium with well-developed leaves as explants. This method is expensive and can only be used in mass production.

The above is for you to introduce the Rieger crabapple breeding methods and breeding methods, I hope to help you, more household knowledge, please pay attention.

The watering method of Rieger Begonia the main points of propagation of Rieger begonia

Rieger Begonia has beautiful flowers and large petals, which is very suitable for potted culture and ornamental at home. How many days does Rieger Begonia water? Today, what the editor of wed114 wedding network brings to you is the watering method of Rieger Begonia.

1. The watering method of Rieger Begonia:

Watering key points

Usually watering Rieger crabapple depends on climatic conditions, usually evaporation is fast in summer, water demand is relatively high, watering should be in the morning or evening, watering times depends on the wetness of the basin soil. Winter watering as far as possible in a sunny day at noon, the water temperature should be close to the indoor air temperature, so as not to cause root stimulation and death because the water temperature is too low. It is best to use a humidifier to increase air humidity, or you can use a sprayer to spray fine mist on the leaves. Just see the leaves are wet, but do not spray water mist on the flowers.

2. Matters needing attention in breeding Rieger Begonia

To apply fertilizer:

Rieger Begonia uses nitrogen fertilizer as the main fertilizer for seedlings to promote its growth and development. With the growth of the plant, the amount of nitrogen fertilizer should be reduced, the content of phosphorus and potassium fertilizer should be gradually increased, the amount of fertilizer should be increased before flowering, and foliar fertilizer can be sprayed properly. the concentration of foliar fertilizer should not be too high, controlled between 1% and 2%, the spray should be uniform, and both sides of the leaf should be sprayed. Rieger begonia is sensitive to nutrient deficiency or excess, so fertilizer should be applied thinly and compound fertilizer at the ratio of 15:5:15 or 20:10:20 can be used to maintain the PH value of the solution between 5.0 and 6.0. According to the nitrogen content of dissolved liquid fertilizer, the concentration of nitrogen applied once a week is 250ppm and 300ppm, and the concentration of nitrogen is 100~200PM three or four times a week or every day. At the same time, Rieger crabapple special fertilizer can also be selected.

Adhering to the principle of frequent application of thin fertilizer, Rieger crabapple is sensitive to the salt content in the soil, and the basin soil can not accumulate too much salt. A compound fertilizer with a nitrogen, phosphorus and potassium ratio of 17:6:13 can be used at the seedling stage, once every 5 to 7 days, with a concentration of less than 0.2%. With the growth of plants, the proportion of nitrogen, phosphorus and potassium in fertilizer should be adjusted, the proportion of nitrogen fertilizer should be gradually reduced, the amount of phosphorus and potassium fertilizer should be increased, the compound fertilizer with nitrogen and potassium ratio at 1:2 should be applied, the concentration of fertilizer should be dilute rather than concentrated, and the application of nitrogen fertilizer should be avoided. Too much nitrogen fertilizer is easy to curl leaves and affect flower shape. When adding phosphorus and potassium fertilizer before flower bud formation, 0.3% potassium dihydrogen phosphate solution can be used to irrigate the root or spray, once every 7 days, twice in succession, to promote the development of flower buds. The basin soil should be kept moist, impermeable and too wet. Too much will lead to water loss and wilting, and in serious cases, the whole plant will die; the basin soil is too wet, and the water fills the soil gap, resulting in serious lack of oxygen in the soil, thus affecting root respiration and causing death. Too wet basin soil is also easy to provide opportunities for the infection of fungi and bacterial diseases, thus affecting the ornamental value of Rieger Begonia.

Pruning essentials:

1. During the growth period, Rieger Begonia should be coring to promote the plant to germinate lateral branches in order to achieve plump plant type, and the excess buds should be removed in time so as not to cause a large amount of nutrient consumption and affect the development of other flowers.

2. After the cool autumn, Rieger Begonia begins to sprout new branches from the base. When it grows to a certain height, the old branch is cut off from the base with a sharp knife, and the amount of water is increased to promote the growth of Rieger Begonia. When the new branches are basically shaped, 3 new branches are retained in each pot, and the rest are all cut off to concentrate nutrients and make Rieger Begonia take shape as soon as possible.

Pest control:

Family cultivation of Rieger Begonia fewer diseases and insect pests, regular spraying of fungicides to prevent bacterial soft rot and powdery mildew, agricultural streptomycin 200ug/g Ta Duoyin 1000 times liquid spray; in the family to prevent air pollution by pesticides, you can make some soil pesticides, the control effect is better, there are the following two common ways: (1) ginger juice plus water, 1:25 ratio spray, can control soft rot and other pathogenic spore germination. (2) 50 grams of dried pepper, 50 times of water, boiling for half an hour, and spraying leaf surface with supernatant can effectively control aphids, red spiders and aphid mites, inhibit plant growth and make new leaves hard or linear.

3. Main points of propagation of Rieger Begonia

Rieger begonia is propagated by sowing method, cutting method or tissue culture method.
