What are the breeding methods and matters needing attention of begonia flowers in Rosaceae? When will it blossom? How many varieties are there?

Begonia flower has always been known as "fairy in the flower". It is one of the unique flower species in China and is a highly ornamental Rosaceae plant. The following is a brief introduction of crabapple flower culture methods and matters needing attention.

Culture method of crabapple flower

1. Soil: Begonia should be planted in a slightly acidic sandy loam rich in humus, loose and well drained.

2. Watering: begonia watering should not only maintain a high air humidity, but also can not make the basin soil too wet; keep a high air humidity, you can often spray water mist on the leaf surface and around the flowerpot. Watering should be dry and wet, and the basin soil should not be waterlogged. If the basin soil is too wet for a long time, it will cause rotten roots and even the death of the whole plant.

3. Sunshine: begonia prefers warm and humid environment, afraid of strong light and semi-overcast environment. It is suitable to scatter light in high temperature season. Sufficient light is required in winter. Flowering of Begonia bulb will be inhibited under short-day conditions. Long-day conditions can promote flowering.

4. Pruning: begonia picks the heart when the seedling is 6 cm high, promotes branching and improves the ornamental value of the whole plant. Light shearing was carried out about 45 days before flowering to promote the early flowering of branch nails.

Plucking after the plant is formed can delay the flowering period. Cut off the residual flower and a tender stem connecting the residual flower in time after flowering to promote the axillary bud germination of the lower branch, and the tender branch can bud and blossom about 10 days after cutting.

5. Fertilization: Begonia needs more watering and fertilization during its growing period. After half a month of planting in the pot, the mature cake fertilizer and water can be applied once, and the light fertilizer and water can be applied every 20-30 days in the later growing period. after the first flower appears, the nitrogen fertilizer should be reduced and the phosphorus and potassium fertilizer should be increased.

6. Insect pests: the common pest of begonia is leaf roll moth, which eats young leaves and flowers with larvae, which directly affects plant growth and flowering. When a small amount occurs, it can be caught manually; in severe cases, it can be prevented by spraying dimethoate diluent.

Matters needing attention

1. Watering and fertilizing

It is appropriate to keep the basin soil moist for watering. Drought and midsummer weather also need to spray water on the leaf surface and the ground, and increasing air humidity is beneficial to growth. Avoid stagnant water in the basin and get caught in the rain, otherwise the roots are easy to rot. In winter, the basin soil is slightly dry, spraying leaves and environment with clean water every 7 days, which not only increases humidity but also makes leaves clean.

During the growth period, thin cake fertilizer and water were applied for about 10 days, and quick-acting phosphate fertilizer was applied in the bud stage. Pay attention to fertilization, do not splash fertilizer on the leaves; flowering and winter and summer should not be fertilized.

2. Light and temperature

The suitable temperature for the growth of bamboo begonia is 18-20 ℃, and it has a well-ventilated and scattered light environment. Measures such as shading, ventilation and water spraying should be taken in high temperature season, and it is better to keep room temperature above 10 ℃ in winter, which can be placed in a place with plenty of sunshine. During the growing season, the family should be exposed to outdoor scattered light once or twice a week, and should be placed in a sunny shelter in winter.

3. Lashing and turning the basin

As the bamboo crabapple plant is relatively tall, it is necessary to use thin bamboo and other things to set up support branches to prevent lodging. At the same time, every spring, we need to turn the basin, change the soil, prune and cut off the weak branches, overlapping branches and residual roots. For the plants that have flowered for 2-3 years, the plants that are too high should be truncated, leaving only 6-10 cm of the stem to germinate new branches.

Propagation method of crabapple flower

Commonly used sowing, ramet and grafting propagation.

Sowing can be sowed in autumn or in spring after sand storage. The seedlings grow slowly and can not blossom until 5 or 6 years later, and often produce variation, so they are only used for rootstock cultivation and cross breeding. Horticultural varieties are often propagated by grafting, with bauhinia or begonia seedlings as rootstocks, branch grafting, bud grafting, branch grafting, split grafting, and bud grafting. Ramets are mostly before sprouting in early spring or after defoliation in autumn and winter.
