Culture method of bamboo begonia

Begonia is a perennial erect or scattered subshrub of the genus Begonia of the family Begoniaceae. It has obliquely obliquely oblong to oblong-ovate fleshy leaves, thick purplish red petiole, light red or white flowers, soft leaves in summer and autumn, and high ornamental value. Potted plants are often used to decorate living rooms, shop windows or decorate family windowsills, balconies, coffee tables and other places. Now let's take a look at the culture methods of bamboo begonias.

Growth habits of Bamboo Begonia

1. Temperature: bamboo begonia grows rapidly in a warm environment, with luxuriant stems and leaves and bright flowers. The suitable temperature for growth is 1924 ℃, and the winter temperature is not lower than 10 ℃, otherwise the leaves are easy to freeze, but the rhizome is more cold-tolerant.

2. Illumination: bamboo begonia is sensitive to light and is suitable for growing in morning light and scattered light. It is easy to cause leaf burns in strong light. The response to photoperiod was very obvious, and the florescence was obviously delayed under the condition of short day light.

3. Soil: bamboo begonia prefers humus soil with good drainage, which is suitable for pH 6.5-7.5. Alkaline or clayey and easy-hardened soil is not conducive to growth, which will lead to short stems and leaves, dim color, and easy to cause yellowing disease.

The Propagation method of Begonia

1. Sowing: usually use a shallow tile basin or sowing box, first cushion the basin with tiles, evenly load the loose and fertile sowing soil, then flatten the seeds gently with an orchard board, spread the seeds evenly, do not need to cover the soil after sowing, watering will wash the seeds, often soak the basin and take it out after wetting, cover the basin mouth with translucent glass to maintain a high humidity in the basin, and keep the room temperature in the semi-shade of 18 ℃. Spray sooner or later. It usually sprouts from 7 to 30 days after sowing.

2. Stem cuttage: stem propagation can be carried out all year round at room temperature, but the effect is the best from April to May. The top of the stem is often selected as cuttings, which are 10 cm long and 15 cm long, with 2 buds, loose and drained fine river sand, perlite or bran ash are used for soil cutting. when cutting, the cuttings should not be buried too deep, half of the cuttings should be kept at high air humidity and 20 ℃ at room temperature. It usually heals and takes root in 9-27 days.

3. Leaf insertion: the effect of leaf insertion propagation is the best in summer and autumn. Choose fully developed mature leaves, put them flat on the sand bed, cut 1 cm cut with a blade at the central main vein of the leaves, each leaf can be cut 4-5 incisions, and then use "n" wire to fasten the leaves on the sand surface. When the soil temperature is lower than 15 ℃, rooting will be delayed, but it will be difficult to take root when it is less than 10 ℃.

4. Root insertion: cut the lower rhizome into 3-5 cm nodes in spring and autumn, insert them obliquely or horizontally on the sand bed, and keep room temperature for 20-22 ℃. And high indoor humidity, so that it produces adventitious roots and adventitious buds. Generally, adventitious roots grow 15-20 days after insertion, and adventitious buds sprout in 30-40 days. When several leaflets are formed, they can be moved into a small basin for maintenance.

Culture methods of Bamboo Begonia

1. Watering: bamboo crabapple belongs to shallow root plant, likes semi-shady, mild and humid environment, its best growth temperature is between 15 and 25 degrees, drought resistance is strong, but it is afraid of waterlogging, so watering of bamboo crabapple should pay attention to dry and wet. It is best to keep the basin soil moist. In the midsummer season, it is necessary to spray water on the leaf surface and the ground, and increasing the humidity of the air will be beneficial to its growth.

2. Fertilization: bamboo begonia likes fertilizer, and fertilization should be carried out by hoeing when the basin soil is dry. Watering after fertilization can facilitate plant absorption, but large fertilizer should not be applied when the stems and leaves are not flourishing or when the pot is newly turned. During the peak growth period in spring, dilute liquid fertilizer is applied every 10 to 15 days. In the summer high temperature season, the plant stops growing and fertilization should be reduced. Fertilization is suspended during flowering and winter.

3. Illumination: bamboo begonia is sensitive to light, suitable for growing in morning light and scattered light, and suitable for long-term cultivation in Nanyang platform. Full sunshine should be given in spring, autumn and winter. Avoid strong light in summer, otherwise the leaves of the plant will turn yellow and grow slowly. The response to photoperiod was very obvious, and the florescence was obviously delayed under the condition of short day light.

4. Pruning: the pruning of bamboo begonia is beneficial to maintain a good plant shape, and if the plant grows too high or the leaves of the lower part of the stem fall off for many years, which causes the plant shape not to look good and affects the ornamental effect, it can be pruned combined with changing pots in spring to facilitate the plant to sprout new branches and produce more bright flowers.

5. Diseases: the prevention and control of diseases and insect pests of bamboo begonia should be carried out in an all-round way. First, it is necessary to strengthen ventilation and light transmission, basin soil can not be wet, let alone let water in the basin. Second, fungicides such as thiophanate methyl and carbendazim are sprayed every semimonthly to prevent the occurrence of diseases. If red spider harm is found, triclofenac 1500 times solution can be sprayed.
