Attention Points for Planting梅花 (Plum Blossoms)
As a classic ornamental plant that defies frost and snow, plum blossoms are deeply favored by horticulture enthusiasts for their unique posture. However, many people often encounter problems such as failure to bloom and slow growth during the planting process, which are often related to improper control of key links such as seedling raising and environmental control.
Complete Process Analysis of Seedling Raising
Seed Treatment and Sand Storage Technique
Select high-quality fruits with a diameter of ≥3cm, use the flowing water method to remove fruit flesh residue, and pay special attention to thoroughly cleaning the suture line of the fruit pit with a soft bristle brush. During sand storage, mix seeds with river sand at a ratio of 1:5, maintain humidity at 60%, and place in an environment of 0-5°C, regularly turning to prevent mildew.
Substrate Proportion and Sowing Time
It is recommended to use a formula of peat soil: perlite: decomposed leaf soil = 3:1:2 as the substrate, with a pH value controlled between 6.0-6.5. For autumn sowing, select 10 days after White Dew, and for spring sowing, wait until the ground temperature is stable at above 8°C. The optimal sowing depth is twice the diameter of the fruit pit.
Key Points for Transplanting and Maintenance
Seedling Management Standards
Thin the seedlings when the third true leaf unfolds, maintaining a spacing of 15cm. Use a sun-shading net with 50% coverage for transition, and in combination with a 0.1% potassium dihydrogen phosphate foliar fertilizer, spray once a week to promote lignification.
Key Points for Planting Operation
Select a planting hole with a north-south orientation, with a diameter 20cm larger than the soil ball. Base fertilizer should be configured at 2kg of decomposed sheep manure plus 200g of bone meal per hole. After planting, use the "three-step and one-lift" compaction method to ensure that the roots are fully in contact with the soil.
Core Techniques for Temperature Control
During the flower bud differentiation period (July-September), it is necessary to maintain a day-night temperature difference of ≥8°C, which can be achieved by spraying water in the evening to cool down. The temperature during the budding period should be stable within the range of 5-7°C, using double-layer greenhouse film plus straw mat coverage to prevent abrupt temperature changes that lead to bud drop.
After mastering these planting tips, it is recommended to establish a maintenance log to record phenological changes. Through a 3-year observation period, one can accurately grasp the growth patterns of plum blossoms under local climatic conditions, ultimately achieving the ornamental effect of flowers full of branches year after year.
