Cultivation method of plum flowers
Plum flowers blooming in early spring are like snow and jade, making them an excellent choice for courtyard landscaping. Although this plum plant in the Rosaceae family has strong adaptability, scientific maintenance can significantly improve the flowering quality and fruit hanging rate. Master the following five core management skills to allow you to easily cultivate luxuriant plum trees. Choosing high-quality sandy loam soil for plum flower cultivation substrate is an ideal substrate for cultivating plum flowers. It is recommended to use a gold ratio of humus soil (40%), river sand (30%), and garden soil (30%). Root pruning and surface soil replacement need to be carried out every 2-3 years. Bone meal (100g/㎡) can be mixed into before planting to enhance soil fertility. It is recommended to use purple sand pots with a diameter of more than 30cm for potted plants to ensure smooth drainage holes. The plum flower nutrition management plan follows the principle of "sufficient base fertilizer and skillful top dressing." After falling leaves in autumn, decomposed sheep manure (3kg/plant) is used as base fertilizer. During the flower bud differentiation period (March), high-phosphorus water-soluble fertilizer (diluted 800 times) was applied, and balanced compound fertilizer (50g/plant) was supplemented after the full flowering period. It is specially recommended to make homemade peel enzyme fertilizer: ferment banana peel and apple peel for 15 days, dilute it 20 times and water it. The plum flower moisture control strategy adopts the "see dry and wet" method. Water is watered every 5-7 days in spring and autumn, once in the morning and evening in summer, and once in winter to once a month. Focus on preventing water accumulation in the plum rainy season. It is recommended to dig an annular drainage ditch (30cm deep) around the crown projection. During the flowering period, spray wetting method is used, and atomizing nozzles are used to moisturize before 10 a.m. every day, and the air humidity is maintained at 60%-70%. The temperature control points of plum flowers are best maintained at 15-22℃ during the growth period. In winter, the trunk needs to be coated with white (lime: sulfur: water =5:1:20) to prevent freezing. When the flowering period is cold in spring, temporary plastic sheds can be built and charcoal firepots can be placed (1 per 5 square meters). In summer, when it exceeds 35℃, a sunshade net (shading rate is 40%) is needed, and the ground is covered with pine needles (5 cm thick) to reduce the surface temperature. Plum flower disease prevention and control plan Bacterial perforation disease occurs frequently in the plum rainy season. In the early stage, garlic extract (100g mashed +1 L of water) can be sprayed every week. In severe cases, use kasugamycin (2000 times solution) and zinc thiazole (1500 times solution) alternately, paying attention to spraying on the back of the leaves. Regularly prune excessively dense branches to keep the crown ventilated and transparent. Plum flower pest response measures During the red spider outbreak period (May to June), yellow sticky insect boards (3 pieces per plant) can be hung, and biological control recommends releasing predatory mites (500 heads/plant). For chemical control, low-toxic agents such as azifenil (3000 times liquid) are preferred, and bagging treatment has better effect after spraying. When clearing the garden in winter, thoroughly clean up fallen leaves and spray lime sulfur mixture.
Through scientific soil allocation, precise fertilization, intelligent water control, temperature regulation and collaborative management of pest and disease control, plum flower plants can achieve an annual growth of 40-60cm. It is recommended to establish a maintenance log to record data on each pruning and fertilization, and adjust management measures in conjunction with the phenological period. By adhering to 3 years of systematic maintenance, you can create high-quality plum trees with double flower volume.
