The cuttage of propagation methods of Rieger Begonia

Thank you very much.

Rieger Begonia

Rieger Begonia is a kind of warm and moist flower plant, mainly distributed in tropical and subtropical regions. Cutting is a common method of propagation. When choosing the method of cutting propagation, we need to know some characteristics of Rieger Begonia first, so that it will be easier to cuttage successfully.

Rieger begonia likes to grow in a well-ventilated environment. And to the light. The requirements of temperature, moisture and fertilizer are very strict. The cutting method must be at the end of autumn and the beginning of winter. Because in this season, it is the time to prune and shape the plant, and the new branches can be cut off as cuttings. Rieger begonia can choose to be cut into branches or leaves. It depends on personal preference. If you choose a branch, the branch should be moderate in length and cut the lower part of the branch into a horseshoe shape with a blade. If you choose to insert leaves, choose six mature leaves that grow vigorously. Through the above simple introduction, this article through the flower friend according to oneself to the Rieger Begonia cutting experience summary, comes to teach everybody. This is more convenient for novice florists to learn.

The female parent selected by Rieger Begonia cuttings must be healthy. According to the results of many experiments, those with stem rot are not suitable for cutting, and unhealthy branches will have small black spots, which will rot soon. The branches of the cuttings are divided into segments, mine are all about ten centimeters stout, and the leaves can also be cut alive, of course, there is no sturdy growth, and it will take a while for him to germinate, and the plant type must be very slow.

Soil matching: you can use pure vermiculite or add half a handful of perlite, pure perlite can also grow roots, but it is not easy to fix, pure vermiculite long root transplantation is not easy to shake the root vermiculite, so it can be one-to-one ratio.

The branch should be cut about 45 °with a blade (the blade should be cut at an angle and face up), then be sure to sit in the shade for 10 minutes (free time) and wait until the section is dry.

Finally, pour water thoroughly after inserting, put in the moisturizing box, this is made by yourself to put the pansy seedlings, you can also use transparent sorting box, or put in a deep box covered with cling film, put it in a place where the light is bright and out of direct sunlight, and maintain the temperature in the range of 10 UV 25 degrees. My balcony survives at 10 degrees in the coldest weather at night.

Reviewing the experience of failure and success, it is concluded that it is not easy to cut in summer, there is no problem in autumn and winter, and the survival in spring is followed by the dangerous period of summer dormancy, so autumn and winter cutting is recommended. Then, the section must be cut across the board with a sharp blade, the medium should be thoroughly watered, and finally moisturizing is the key, otherwise the leaves will wilt ahead of time. The humidity had better be kept at 80. I used to insert a lot of water droplets on the film. It will take root in 20-30 days and can be transplanted in loose and breathable soil after 2 months, preferably a mixture of peat plus a little vermiculite and perlite. Cymbals

Propagation method of Rieger Begonia cutting propagation method of Rieger begonia

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

2. 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.

3. Insert the cuttings into the substrate, water them thoroughly, cover them with plastic film and put 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.

Example of Leaf insertion Operation of Rieger Begonia

1. Rieger Begonia leaf insertion preparation material, healthy Rieger Begonia, sterilized knife, 1 mineral water bottle, fungicide, 1 flowerpot, peat soil mixed with a small amount of perlite.

2. The Prime Minister will dig a 1 cm wide opening in the middle of the mineral water bottle and fill the water bottle with pure water.

3. Take the good leaves from Rieger Begonia, pay attention to selecting the greener leaves that are easier to root, cut across the board from the petiole close to the trunk with a knife, smear the fungicide on the cut and let it dry for more than ten minutes.

4. Then insert the leaf into the mouth of the mineral water bottle and put the bottle in a warm place to take root more easily, which can take root in about a month or so.

5. All the leaves of Rieger Begonia should be pseudo-planted after taking root. Put the peat soil in a pot, transplant the leaves into the flowerpot and wait for them to sprout.

Method of sowing and breeding of Rieger Begonia

1. 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.

2. 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.

3. 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.

How to propagate Rieger Begonia Reproduction methods of Rieger Begonia

In late autumn and early winter, when trimming Rieger Begonia, the new branches can be used as cuttings. Do you know how to reproduce Rieger Begonia? Let's take a look at the breeding method of Rieger Begonia.

The propagation of Rieger Begonia mainly includes three methods: sowing, cutting and tissue culture, and the cutting method is commonly used. In late autumn and early winter, when trimming Rieger Begonia, the cut new branches can be used as cuttings.

1. Cutting method of Rieger crabapple.

Rieger begonia can be cut not only in branches but also in leaves. When the branch is inserted, the length of the branch should be moderate, and the lower part of the branch should be cut into horseshoe shape with a blade. When inserting the leaves of Rieger Begonia, six mature leaves with vigorous growth should be selected and the lower end of the petiole should be obliquely cut with a blade.

The cutting substrate of Rieger Begonia 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 the branches of Rieger Begonia grow new leaves, it shows that they have taken root. Rieger Begonia obtained by branch cutting method has no underground tubers. 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.

2. Sowing method

Because the seeds of Rieger Begonia are very small, the small seed sowing method must be used. At present, the seeds of Rieger Begonia are basically imported, including sub-coated and uncoated seeds. It is best to mail-order the original packaged and undamaged seeds from large flower and tree companies, so as to ensure that they can germinate into seedlings, and it is difficult for seeds in bulk to germinate.

Sowing container: Rieger begonia coated seeds can be sorted, can be used hole seedling plate, non-coated seeds can only use 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.

Rieger crabapple does not need to be covered with soil after sowing, only spray with a fine spray can, and then wrap the seedling tray with transparent plastic film. Under the condition of ambient temperature of about 20 ℃, seedlings began to emerge in about 12 days. When Rieger Begonia seedlings grow true leaves, they can be properly ventilated to promote their roots.

Rieger begonia grows 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. When the weather is cool after autumn, you can gradually peel off the plastic film and put it on the pot in early winter.

The upper pot can use a smaller flowerpot with porous bottom, and 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. in this way, the roots can not be hurt when the seedlings are raised.

Rieger Begonia seedlings just on the pot to prevent the weather change 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, Rieger crabapple can not grow into a large plant in the first year, but flowers can be seen in the first year. It can only be cultivated into a large plant in the second year, and a larger flowerpot can be changed in the second year.

3. Tissue culture

This is an effective way to quickly obtain a large number of flower seedlings of Rieger Begonia, and it can also be successful under family conditions. In the vigorous growing season of Rieger Begonia, 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.
