Flowers are red and leaves are green. They should be planted in the corners of lakes, streams, small yards, roadsides or in front of buildings.
Xifu Begonia is a small tree with a height of 8 meters.
Branchlets are red, leaves are oval to oblong, 5 ~ 8 cm long, the apex is short and sharp, the base is wide wedge-shaped to round, and the leaf margin is serrated.
The flower is very red in bud, pale pink after opening, single or double.
Fruit subglobose, yellow.
The flowering period is from April to May.
Common varieties are: double pink begonia, double flower, larger, pink; Double white sea otters, double white flowers.
Xifu begonia likes light, cold, drought and waterlogging.
It grows well in the arid areas in the north.
The flower buds of Haitang Xifu are terminal or axillary mixed buds, which belong to summer and autumn differentiation type, and the concentrated differentiation period is July-August every year.
Most flower buds are planted on short branches below 5 cm and middle branches of 5 ~ 12 cm; The long branches over 20 cm are mostly vegetative branches, and rarely form flower buds.
The opening angle of the main branch of Xifu Begonia is small, and the tree shape is steep, so it is better to use multi-leader trunk shape for plastic surgery.
After the seedlings survive, 60 ~ 100 cm should be reserved for short cutting in the first year of winter cutting.
In the growing season of the second year, several branches are selected, 3-5 branches are selected as main branches above 30-40 cm from the ground, and the rest branches are all cut off to save nutrients.
The next winter, the selected main branches will be cut short, and the length of cutting short depends on the tree potential. Generally, the branches with good growth are cut short by 30 ~ 50 cm, and the outer buds or lateral buds are left at the incision.
When cutting in the winter of the third year, choose to leave lateral branches at an appropriate position above the main branches, leave 30 ~ 40 cm for short cutting, or leave external buds or lateral buds at the cutting mouth.
In the following year, choose to leave the secondary branch on the secondary branch, leave the branch on the secondary branch appropriately, and so on.
Thinning the long branches and weak branches that are of no use value every year, and appropriately pruning the long branches that are of use value.
On the one hand, it is necessary for plastic surgery, on the other hand, it can promote the germination of lateral buds under the incision and form short and medium branches, which is beneficial to the formation of flower buds.
This molding can form a beautiful bottle shape, which can bloom early, and the tree shape and branch shape can be seen in winter.
After the aging of Xifu Begonia tree, the big branches with few branchlets can be sawed off before germination, and the strength can be retracted.
The incision should be leveled with a sharp knife to facilitate healing.
In the growing season, new branches germinate, strong branches are selected to stay and continue to cultivate, and weak branches are cut off, so that after a period of time, old branches bloom again and regain their vitality.
Most erect tillers often germinate in the trunk or the base of the main branch, and branches with suitable direction and vigorous growth can be selected as regenerated branches, and the aged branches can be cut off year by year.
