Is Xifu Begonia a deciduous tree or an evergreen tree?

Xifu Begonia is a plant belonging to Magnoliaceae, Rosaceae and Malus. For China's endemic plants, in the northern dry zone growth well, is the greening project in the more popular products. So, West House begonia is deciduous tree or evergreen tree?

Is it a deciduous tree or an evergreen tree?

Xifu begonia is a deciduous small tree, up to 2.5-5 meters high, branches erect strong; branchlets thin cylindrical, pubescent when young, deciduous when old, purple or dark brown, with sparse prickles; winter buds ovate, apex acute, glabrous or only margin tomentose, dark purple.

II. Breeding methods

Begonia is usually propagated by grafting or splitting, but can also be propagated by sowing, layering and rooting. Grafted seedlings can flower earlier and retain their original fine characteristics.

1. Sowing method

Although the seedlings grow slowly, they often produce variation, so in order to obtain a large number of rootstocks or crossbreeding, sowing method is still used. The rootstock species commonly used in northern China include Mountain Stator, Xifu Malus, and Malus fragrans, etc.; in the south, Malus hupehensis is used. Begonia seeds must undergo stratification treatment at low temperature for 30 to 100 days before sowing. Fully stratified seeds germinate quickly and neatly, and the germination rate is high; seeds that are not stratified cannot germinate, or germinate very rarely. Can also be picked in autumn fruit, to the meat, a little after drying that is, sowing in the sand bed, so that the seeds naturally ripen. The depth of soil covering is about 1 cm, plastic film is covered to preserve moisture, plastic film is removed after seedling emergence, a layer of loose fertilizer soil is scattered in time, fertilizer and water management is strengthened at seedling stage, and it can be transplanted in late autumn of that year.

2. Grafting method

The seedlings which are sown and propagated are taken as rootstocks for branch grafting or bud grafting. Grafting or budding. In spring, the sap flows and germinates for branch grafting, and in autumn (July ~ September), bud grafting can be carried out. Branches can be cut, split and other methods. Scion selection of full development of 1-year-old branches, take the middle section (there are more than 2 full buds), after grafting on fine soil cover scion, bud grafting more with "T" word grafting method, after about 10 days, where the bud fresh, petiole that one corner fell for the proof of grafting, a few days later can remove the binding. When the seedling height is 80 cm ~100 cm, the backbone branches are formed, and then only over-dense branches, inward branches, overlapping branches are pruned, and the crown is kept round.

3. Plant division method

before budding in early spring or after defoliation in autumn and winter, picking the tillers sprouting from the rhizosphere, dividing into a plurality of individual plants, or grouping 2 - 3 sprouts with roots into a cluster for transplanting. After sub-planting, it is necessary to irrigate thoroughly in time, pay attention to moisture preservation, shade when necessary, and irrigate when dry.
