1、 Sowing and propagation

In the flowering period of Begonia longwinged, artificial pollination can be carried out to produce fruits and seeds, but the seeds obtained by artificial pollination are very small. If they are directly used for planting, the germination rate is very low, so the method of artificial pollination is generally not used. Generally, seeds imported from abroad are used for sowing and breeding. Such seeds have full grains, and the coating also contains a lot of nutrients and fungicides, which are easier to germinate after sowing

Dragon winged Begonia is sown in spring and early autumn. The soil to be planted should be loose and fertile weak acid soil. After putting the seeds into the soil hole, spray water first to melt the coating, and then bury them. The soil should be kept moist during germination. The temperature should be kept at about 25 ℃, and germination can take about half a month

After the seedlings grow two leaves, it is necessary to reduce the temperature. About 18-20 ℃ is more suitable for seedling growth, gradually increase the sunlight, spray water frequently to keep the soil and leaves moist, and spray liquid nitrogen fertilizer once a week. After the seedlings grow five or six leaves, they can be transplanted

2、 Cutting propagation

Cutting propagation is best carried out in spring or autumn. Because of the high temperature and damp heat in summer, the cuttings are easy to rot and not easy to survive. When cutting, select strong branches with terminal buds and two or three young leaves, with a length of about 15cm. Cut them close to the branches, and insert about half the length of the branches into the soil. After that, put the flower pot with cuttings in a semi shady place, and often spray water to keep the soil and leaves moist. It can take about three weeks to take root

3、 Tissue culture and reproduction

Tissue culture is the main breeding method of Begonia longwinged. Generally, twigs and leaves are used. After washing and disinfecting, the short segment with a length of about 1cm is added to the culture medium. After transformation and culture, complete seedlings can be transplanted. After transplantation, place it in the semi shade and pay attention to ventilation. It is best to maintain the temperature at about 25 ℃. Spray water to ensure water. After a week, gradually increase light and nutrition, and you can go to the basin in about 40 days. The survival rate of Begonia longwinged bred by this method can reach more than 95%
