How to reproduce Silver Star Begonia
A little knowledge to share with you the content of how to reproduce Silver Star Begonia and the green planting and flower cutting methods of Silver Star Begonia. Let's learn about it together.
Silver star begonia is a perennial herb of the genus Begonia in the Begonia family, also known as Mayleaf begonia. For beautiful ornamental flowers. Begonia flowers are used to make bonsai, and the cut branches can be used for vase inserts and other decorations. Begonia flowers have strong resistance to sulfur dioxide and are suitable for greening urban street green spaces and Kuangqu. The crabapple tree is beautiful and has blooming spring flowers. After autumn, the tree is filled with golden fruits and fragrant. It should be planted alone in front and back of the courtyard, opposite the entrance of the entrance hall, in clusters on the corners of the lawn, or with other flowers and trees. It can also dwarf potted plants.
Silver Star Begonia is a shrub type. It prefers warm, humid, shaded and ventilated environments. It is not cold resistant. It is used as potted plants in all parts of North China and is moved indoors to wintering in winter. The suitable temperature for growth is 19-24℃, and the temperature in winter is not lower than 10℃. Otherwise, the leaves are easily frozen, but the roots are relatively cold-resistant.
1. Silver star begonia breeding methods: Silver star begonia breeding methods include cuttage propagation and seed propagation.
1. Stem cutting, leaf cutting and rhizome cutting can be used.
Stem cutting: Stem cutting propagation can be carried out all year round at room temperature, but the effect is best from April to May, with fast rooting and high survival rate. The top of the strong stem is often selected for cutting, 8-12 cm long, and every 3-4 buds are a section. It is best not to use the top stem with flower buds for cutting. Use loose and well-drained fine river sand, perlite or bran ash for transplanting soil. When cuttage, the cuttings should not be buried too deep, but half of the cuttings should be suitable, and maintain high air humidity and room temperature of 20-24℃. Rooting can take root generally within 25-30 days after transplanting, and can be placed in pots after rooting.
Leaf cutting: Leaf cutting reproduction has the best effect in summer and autumn. Cultivation at room temperature can also be carried out in winter, but rooting is slow. Leaf cutting materials should be selected from mature leaves that are fully developed, leaves that are too tender or aging, which will heal slowly, and have a low seedling formation rate. For larger types of leaves, the flat insertion method can be used. Lay the leaves flat on the sand bed, use a blade to make a 1 cm incision at the central main vein of the leaves. Each leaf can make 4-5 incisions, and then use an "n" iron wire to fasten the leaves. Fasten the leaves to the sand surface, or use pebbles with a diameter of 1.5-2 cm can be pressed around the blade incision, so that small plants can grow from the vein incision. For example, during the cuttage process, if the soil insertion temperature is lower than 15℃, rooting will be delayed, and if it is lower than 10℃, it will be difficult to take root.
Root insertion: Suitable for Begonias with dense roots. Cut the low roots into 3-5 cm sections in spring and autumn, insert them obliquely or flat on a sand bed, and keep room temperature at 20-22℃. And higher indoor humidity, so that it produces adventitious roots and adventitious buds. Generally, adventitious roots will grow 15-20 days after transplanting, and adventitious buds will germinate within 30-40 days. When several small leaves are formed, they can be moved into a small pot for maintenance.
Water cutting: The survival rate of water cutting is high, generally reaching 100%. Water cutting can be carried out throughout the year. The operation method of water cutting is to select strong and mature branches that are free of pests and diseases, and have children two years old. Cut branches about 8-12 cm long, remove the flower ears, keep the upper 3-4 leaves, and cut the cut flat. The cut is preferably under the lowest section of the cutting ear. Soak in 0.1% potassium permanganate solution for 2-3 minutes before cuttage. Fill the glass bottle with water, then insert the Silver Star Begonia cuttings, and cut off some of the leaves in order to reduce moisture evaporation from the leaves. Then place the glass bottle in a place under direct sunlight, change the water every 1-2 days, keep the water temperature at 20-30 ° C, take root after 10-30 days, and wait until the roots develop fully, you can put it into the pot.
2. Layered propagation: Lasting can be carried out in winter or spring, and usually low-pressure and high-pressure breeding are used. Low-pressure breeding is in early spring, selecting branches close to the ground, and using a knife to girdle a 1 cm incision (The position of the incision is better so that the incision is just buried in the soil when the branch is pressed into the soil.) Just bury the incision in the soil and fix it, press it with stones to make the branch upward and prevent the branch from swinging. During the planting season, peel open the pressing soil and observe, and cut off the strips that have already grown roots from the end near the parent plant. 3. Seed reproduction: Usually sowing in a shallow tile pot, and evenly mixed with high-temperature disinfected legume soil, culture soil and fine sand is the best. First, use tiles to pad the bottom of the basin, evenly fill it with loose and fertile sowing soil, and then gently flatten it, spread the seeds evenly. After sowing, there is no need to cover with soil. Just press it lightly with a wooden board. Pay attention to spraying. Water will disperse the seeds. Usually, put the basin into a shallow water basin and soak it from the bottom of the basin, and remove it after wetting. At the same time, glass is placed on the lid of the pot to maintain high humidity in the pot, and place it in a semi-shaded place at room temperature of 18-22℃. Spray it in the morning and evening, and germinate generally 7-30 days after sowing.
2. Preparation of basin soil: Home planting Silver Star Begonias usually use potted plants. Potting plants must first prepare cultivation soil. Preparing cultivation soil is important. flowerpots are a special small environment. No matter which kind of soil is used alone, it cannot meet the needs of Silver Star Begonias in all aspects of soil. Therefore, potted Silver Star Begonias must be artificially prepared and cultivated soil to replace soil to fix the flowers in the flowerpot. They must have certain water retention and drainage properties, and must be loose, fertile, It has good air permeability, and potted Silver Star Begonias are commonly used with compost soil, leaf soil and charcoal soil. Pay attention to the use of alkaline or sticky soil that is easy to harden for potted purposes, which is not conducive to the growth of new roots, resulting in short stems and leaves, dull color, and easy to cause chlorosis. Suitable for growing in neutral soil with pH 6.5-7.5. After preparing the culture soil, it is best to disinfect it at high temperature (stir-fry it in an iron pan) and use it, or it can be exposed to the sun to sterilize it.
3. Potion: First put broken tiles at the bottom of the flowerpot, then put some decomposed cake fertilizer, crushed bones, fish bones, chicken feathers and other basic fertilizers, then fill in the culture soil, cut off the long lateral roots, injured roots and excess fibrous roots during planting, and prune the upper branches once. Pay attention to stretch the root system during cultivation. Fill the soil into half of the pot, gently lift and shake the silver star begonia plant, and compact the culture soil. When planting, it should not be too deep. Just keep the rhizome level with the mouth of the pot. If it is shallow, it will affect survival, but if it is deep, it will affect the growth of Silver Star Begonia after transplantation. It will be watered once after planting. After cultivation, maintain it in a shaded environment for about a week, and wait for the roots to recover and move it to a sunny place for maintenance.
4. Management 1. Shade: Silver star begonia should be cultivated in a greenhouse and properly shaded. Because the greenhouse environment can better protect plants, such as rainwater falling on the plants. If begonia leaves are too wet, they can easily infect bacterial spot disease, which is a serious disease. When moving outdoors in summer, place it in a darker place that is not wet.
2. Pots change and pruning: Pots change every 1-2 years. Pots change and pruning are carried out in early spring and April. The pots are made of mud pots with good drainage. After 1-2 years of flowering, most of the branches are thin and thin. Conduct one pruning, leave only 2-3 buds at the base of the lateral branches, and cut off all the upper parts. Combined with pot change and soil application, apply base fertilizer to promote the germination of strong new branches.
3. Water and fertilizer management: Spray leaf surfaces and ground every evening in summer to maintain air humidity, and keep the relative humidity at 56%-60%. In this way, the stems and leaves grow luxuriantly, are bright in color and delicate. Pour fully decomposed thin liquid fertilizer every 10-15 days.
4. Overwintering management: Move it indoors for maintenance before the Cold Dew Festival in early October. Water should be controlled. Spray the leaves with warm water every 7-10 days, and keep the temperature above 12℃.
