The fruit of Chimonanthus praecox is poppy-shaped, and the fruiting period is April-165438+1October. It is green when it first grows, and it will turn reddish brown as it grows longer.
It is named "Chimonanthus praecox", "Chimonanthus praecox" or "Huang Meihua" because of its yellow color, plum blossom-like petals and blooming in the twelfth lunar month. Li Shizhen's Compendium of Materia Medica records: "Chimonanthus praecox, named Huang Meihua, is not plum, so it is named because it is similar to plum in fragrance and color".
Chimonanthus praecox blooms in winter, and its fragrance is incomparable. It blooms in the winter when flowers are dying, and it is one of the precious flowers in China. Chimonanthus praecox is cold-tolerant and drought-tolerant, and likes light environment. Generally, its propagation is mainly based on grafting, and it can also be divided into plants, sowing, cutting and layering.
cultivation techniques
Grafting, cutting and ramet propagation are adopted, and grafting propagation is the main method. Grafting can use seedlings or ramets as rootstocks for cutting or budding. Cutting can be carried out after leaf buds germinate in spring, and bud grafting can be carried out in rainy season. After the grafting survives, the tillers grown on the rootstock should be removed in time. Chimonanthus praecox has thick branches, so it should be pruned when it is cultivated to keep the tree beautiful.
Pruning can be done after flowering and before leaf development. Long branches should be cut short appropriately to promote many short and strong flower branches. Most annual branches can form flower buds. After germination, young fruits should be cut off to concentrate nutrition and form new flower buds. Fertilize once after leaves or flowers wither, apply liquid fertilizer 2 ~ 3 times in summer, and change pots of potted Chimonanthus praecox every 2 ~ 3 years.
