The large-leaved begonia, also known as the bamboo begonia, is a popular ornamental plant that is widely loved for its beautiful flowers and easy-to-manage properties. This article will introduce the cultivation techniques and propagation methods of large-leaved begonias.
1. Cultivation technology
1. Soil selection: Begonia macrophylla is suitable for growing in well-drained, fertile, organic matter-rich soil. Therefore, it is very important to choose such soil for cultivation.
2. Planting depth: When planting large-leaved begonias, make sure that the root system is fully extended, but not too deep. When filling the soil, it should be gently compacted and ensure that the soil is in full contact with the root system.
3. Watering management: Begonias need plenty of water, but too much water can cause root rot. Therefore, watering should ensure that the soil is moist but not too wet. In dry weather, regular watering should be done to retain moisture.
4. Light requirements: Begonias need adequate sunlight to promote their growth and flowering. Therefore, it should be placed in a sunny place and avoid prolonged exposure to shady environments.
5. Fertilization management: In order to promote the growth and flowering of large-leaved begonias, regular fertilization is required. The use of organic fertilizer or compound fertilizer can provide sufficient nutrients.
II. Breeding method
1. Split propagation: Begonias can be propagated rapidly through ramification. Divide the mother plant into several smaller plants in spring or autumn and plant them separately in the new soil.
2. Propagation by cuttings: Begonias can also be propagated quickly by propagation by cuttings. Select a sturdy shoot, cut it about 10 cm long, insert it into a substrate mixed with peat soil and perlite, keep it moist and properly shaded, and it will take about 2-3 months to take root.
3. Sowing and propagating: Begonias can be cultivated through sowing propagation. After harvesting the seeds in autumn, seeds can be sown, and the seeds can be sown on a loose and breathable substrate, kept moist and properly shaded, and germination can be carried out in about 2-3 months.
Begonia macrophylla is a popular ornamental plant, and attention needs to be paid to the selection of suitable soil, watering management, light requirements and fertilization management during the cultivation process. At the same time, methods such as ramification, cuttings propagation and sowing propagation can be used for rapid propagation and cultivation of new varieties. In the process of maintenance, it is necessary to pay attention to the growth of the plant, and deal with the problem of pests and diseases in time to ensure the healthy growth of the plant and good ornamental effect.
