Peony fertilization method
As the king of flowers, peony's elegant attitude is inseparable from scientific fertilization management. Correct fertilization methods can not only promote root development, but also allow peonies to bloom with double petals every year. This article will systematically analyze the golden rule of peony fertilization and help you master the essence of Kao maintenance. 1. Peony fertilization time three stages 1. During the pre-flowering nutrient storage period, phosphorus and potassium fertilizers are applied in early spring and before germination (about late March) to promote flower bud differentiation. At this time, when the ground temperature rises to 5℃, it can be irrigated with decomposed bean cake water to make the flower buds full and large. 2. During the post-flowering restoration period, after flowers wither in late May, nitrogen, phosphorus and potassium compound fertilizers will be applied immediately to replenish the nutrients consumed by flowering. It is recommended to use water-soluble fertilizer in a ratio of 1:1:1 and cooperate with loosening soil to improve the absorption rate. 3. During the winter energy storage period, in early November, before freezing, rotten manure is applied around the plants. The amount per mu is controlled within 2000 kilograms, which not only protects heat and freezes, but also reserves energy for growth in the coming year. 2. Guide for the Selection of Peony Fertilizers The ratio of organic fertilizers to inorganic fertilizers is recommended to account for 60% of the growth period, and slow-release fertilizers such as rapeseed cake and bone meal are recommended. Add inorganic fertilizers such as potassium dihydrogen phosphate during the flower bud period, and the concentration is strictly controlled at 0.2%-0.3%. The trace element supplement program supplements chelated iron fertilizer every two years to prevent yellow leaf disease. Spraying borax solution (concentration of 0.1%) before flowering can effectively prevent buds from falling. 3. Technical points of fertilization operation The liquid fertilizer application specification adopts the secondary dilution method: first dissolve the original solution with 10 times water, and then add water to 100 times application. Water along the edge of the basin on sunny days and evenings to avoid touching the base of the stem. Solid fertilizer burial techniques excavate an annular ditch 20cm away from the main trunk with a depth of 15-20cm. Mix decomposed sheep manure and garden soil at a ratio of 1:3 and then backfill it, paying attention to keep root breathing smooth. 4. Strategies for coping with special situations Spread plant ash (50 kilograms per mu) before the rainy season, which can not only replenish potassium but also adjust the soil pH and alkali value. When fertilizer damage was discovered, the roots were immediately sprinkled with clear water three times, and 1/3 of the leaves were pruned to reduce transpiration.
By mastering these fertilization tips and combining with the principle of "applying thin fertilizer and diligent", your peony will surely show the unparalleled beauty of "national beauty and fragrance." Remember to stop fertilization during the high summer heat period (July-August) to allow the plants to naturally enter a semi-dormant state and accumulate strength for the next growth cycle.
