It is a commonly cultivated fruit tree and ornamental tree with upright tree posture, dense flowers, a wide variety of cultivation varieties, and is deeply loved by the people.

The Culture method of Begonia in Xifu

1. Planting: Tripterygium is generally planted in many rows, and it is appropriate to keep the complete root system of the seedling when it comes out of the nursery, and the seedlings should stay in the soil according to the situation. after planting, the tending management should be strengthened and the seedlings should be kept loose and fertile.

2. Watering and fertilization: Xifu crabapple needs more watering in spring and summer, timely and adequate watering in hot summer, such as lack of water, leaf edge is easy to scorch, watering is gradually reduced after cool autumn, and less watering after defoliation in winter to prevent rotting roots. However, because the western begonia is a deciduous tree species, it is not suitable to spray too much water on the branches and leaves. Xifu begonia likes fertilizer, which can be applied more appropriately, and attention should be paid to the combined use of nitrogen, phosphorus and potassium. If nitrogen fertilizer is used too much, it is easy to cause the phenomenon of luxuriant branches and leaves and sparse flowering. After flowering in spring, nitrogen fertilizer is mainly applied to promote the growth of branches and leaves. More phosphorus and potassium fertilizers are applied in summer and autumn to facilitate flower bud differentiation and ensure flowers blooming and colorful. Fertilizer can be used as cake fertilizer, human feces and urine, bone meal, chicken dung, fishy water and so on.

3. Pruning: Western begonia has strong germination and fast growth, so we should pay attention to the shaping and pruning of Xifu crabapple. After falling leaves in winter to before sprouting in spring, disorderly branches such as withered branches, disease and insect branches, thin and weak branches, crossed branches, overlapping branches and over-dense branches can be cut off. After blooming in spring, we can truncate the overlong branches appropriately according to the modeling needs, promote the division of lateral branches, increase the number of flower buds, and ensure that there are many flowers in the coming year. In addition, after sprouting in spring, too many bud heads that are too dense and poorly positioned can be erased.

4. Disinfestation: Xifu begonia should pay attention to the control of beetles, leaf rollers, aphids, pocket moths, red spiders and other pests, as well as rot, red star disease and so on. Prevention and treatment can remove diseased trees, burn diseased branches, reduce the source of germs, spray stone-sulfur mixture in early spring or brush the tree trunk with lime. At the beginning of the disease, it can be cut into knife marks of about 0.5 cm in vertical and horizontal directions, reaching to the xylem, and then spraying fungicides.

The Propagation Mode of Begonia Xifu

1. Grafting method: the buds and branches of Xifu begonia are grafted, and the rootstocks are mostly used as seedlings of the same genus. The bud grafting of begonia should be carried out in August and the branch grafting should be carried out in spring.

2. The method of burying roots: from February to March in early spring, the root of the adult begonia will grow about 15 centimeters, put it flat and bury it in the soil, cover the soil 7 centimeters, pour water thoroughly, and often keep the soil moist afterwards.

3. The method of dividing plants: the splitting of Malus sinensis is suitable in early spring in March, before sprouting, the seedlings will sprout around the begonia of some years, and the seedlings will be cut off from the mother plant with roots, which should be properly shaded to keep the soil moist.

Points for attention of Begonia XIFU

1, do not shine directly, lest damage leaves, winter should be placed in the sunny shelter for maintenance, hot and dry summer season should pay attention to ventilation shade, can not always shine on the sun.

2. When pruning, Xifu begonia can cut off worthless long branches and thin branches every year, and cut the rest of the long branches short. When the plant of Begonia is in a state of senescence, it can cut off some larger branches, which can make the branches shrink, and the new branches need to cut off the thin branches during the growth period. Except for the branches that grow stronger and in the right direction, the senescent branches can be cut off.
