How to Propagate Winter plum blossom
Winter plum blossom is favored by horticulture enthusiasts for its ability to bloom in the cold. Mastering the correct propagation techniques is key to cultivating high-quality plants. This article systematically analyzes three mainstream propagation methods for Winter plum blossom, using actual operation illustrations and detailed key points to help you master the entire process from propagation to maintenance.
Core Propagation Technology of Winter plum blossom
Key Points of Grafting Propagation Technique
The best grafting period is from March to April in spring, selecting sturdy one-year-old branches with a diameter of 0.8-1cm from dog-tooth plum blossom seedlings as the rootstock. Scions should be collected from the healthy one-year-old branches of flowering mother plants, retaining 2-3 full bud points. When using the cut grafting method, the depth of the rootstock cut must reach 2cm into the xylem, and the length of the scion cut surface should be equal to the length of the rootstock cut, aligning the cambium layers and binding with elastic film. During the critical care period, the soil moisture should be maintained at 60%-70%, and a sunshade shed should be set up to avoid direct sunlight. Check the formation of callus after 20 days.
Standard Operation of Seed Propagation
Harvest the brown mature capsules in July, and after sun-drying and dehusking, soak in 40°C warm water for 48 hours to break the waxy layer. Stratification with sand should be mixed in a ratio of seeds to river sand of 1:3, maintaining humidity at around 25%, and regularly turned to prevent mildew. In March of the following year, broadcast sow with a row spacing of 30cm and a sowing depth of 2-3cm, then cover with plastic film to keep warm. Seedlings should be thinned in time, maintaining a spacing of 15-20cm, and diluted cake fertilizer water should be applied every half month during the growing period to promote lignification.
Implementation Steps of Division Propagation
Select丛生 mother plants that are over 3 years old and divide them before the early spring germination. During the operation, retain a soil ball with a radius of 40cm, and use a sharp blade disinfected with potassium permanganate to split along the natural branching points, ensuring each cluster has 3-5 main branches and a complete root system. The planting hole should be pre-fertilized with decomposed manure, and the planting depth should be kept level with the original soil mark and the ground surface. During the slow seedling period, a windbreak should be set up, and a spray method should be used to maintain an air humidity of over 70%, gradually increasing the light intensity after new buds sprout.
