When will the potted plum blossoms be replaced?
As the first of the famous traditional flowers in China, plum blossoms occupy an important position in bonsai art. The pot changing operation of potted plum blossoms directly affects the growth trend and flowering quality of the plant. Mastering the correct pot changing techniques can keep the plum piles full of vitality and bloom with proud and cold fragrance every year. 1. The best time to change potted plum blossoms 1.1 Spring golden pot change period Early spring February to March when the temperature warms is the best window period for pot change. At this time, the plum blossoms are in the early stage of germination, and the tree sap begins to flow but has not fully recovered. Select continuous sunny weather to operate to avoid root rot caused by high humidity in the rainy season. Experimental data shows that the survival rate of plum blossoms when pots are changed in spring can reach 98%, and the rate of new roots germination is 40% faster than that in autumn. 1.2 Emergency treatment for special circumstances When pot soil is hardened, root systems are exposed, or pests and diseases are serious, pots can be changed in autumn through the routine. After operation, a sunshade needs to be built to maintain the environmental humidity of about 70%, and use rooting agents to promote recovery. 2. Technical key points of the whole process of plum blossom pot changing 2.1 Fine management of root systems and three-level pruning method is used after removing the pot: first remove 1/3 of the outer soil, cut off black rot roots and excessively dense roots, and retain the main root length of 15-20cm. Apply a wound healing agent to incisions with a diameter of> 0.5 cm to prevent bacterial infection. 2.2 The substrate is scientifically proportioned and the new soil is prepared according to the ratio of red jade soil: humus soil: river sand =5:3:2. 20g of bone meal and 50g of cake fertilizer are added to each kilogram of substrate as base fertilizers. Sunk it for 3 days before use, and disinfect it with microwave for 5 minutes to kill eggs. 2.3 The standard purple sand basin is the first choice for pots. The diameter of the new basin is 5-8cm larger than the original basin. Deep barrel pots are suitable for straight-root plum piles, and shallow mouth pots are conducive to displaying open-root shapes. A 3cm ceramite drainage layer is placed on the bottom of the basin to prevent stagnant water and rotten roots. 3. Key maintenance stages after pot change 3.1 Slow seedling management The root water must be thoroughly watered, and the soil moisture must be maintained for the next 15 days. Build a shade with a shading rate of 70%, and spray leaf surfaces in the morning and evening to increase humidity. The light is gradually increased after the new buds germinate 2 cm. 3.2 The rhythm of nutrition supplementation begins 30 days after changing pots, and applies special organic liquid fertilizer for plum blossoms diluted 1000 times, once every 10 days. Add phosphorus and potassium fertilizers during flower bud differentiation period, and use EM inoculant to improve the soil environment.
Master the time and space code for plum blossoms to change pots, and let the century-old plum piles glow with new life. From grasping the seasons to processing the details, every link is related to the survival of the plant. Only by following the laws of nature and integrating scientific methods can we reproduce the beauty of the artistic conception of "thin shadows, horizontal slopes, clear and shallow waters" in the square basin.
