Peony flower potted domestication method
Peony flowers are known as the king of flowers, and potted planting makes courtyards and balconies show their national beauty. Through scientific maintenance methods, even non-professionals can make peonies bloom year after year. This article will systematically explain the key points of peony potted cultivation from five dimensions, helping you master all management skills from soil allocation to temperature control. The scientific ratio of pot soil and flowerpot selection standard recommends using breathable materials such as pottery pots or purple sand pots. The pot diameter is 15-20 cm larger than the root diameter. There must be 3-5 drainage holes at the bottom to prevent stagnant water and root rot. The soil formula is optimized to mix the humus soil: river sand: garden soil =4:3:3, and add 500 grams of bone meal per cubic meter. Add 2 kilograms of decomposed sheep manure when changing pots every year to ensure a continuous supply of nutrients. The substrate disinfection treatment uses boiling water to pour it through or sun exposure for 3 days, and then sprays 50% carbendazim with 800 times solution to kill bacterial eggs in the soil. Intelligent lighting control seasonal lighting strategy Maintain full sunshine for 6-8 hours in spring and autumn, use sunshade nets to filter 50% strong light from 10:00 to 15:00 in summer, and move it into an enclosed balcony to receive direct light in winter. Flower bud differentiation and management during the flower bud formation period from September to November, ensuring that daily light is ≥5 hours. Using a fill light to extend the light can increase the number of flower buds. Precise management of water and fertilizer dry and wet cycles control the water when the topsoil is 3cm dry in spring and autumn, spray in the morning and evening in summer to increase humidity, and control the water until the soil moisture content is 30%. The nutritional cycle supplies nitrogen, phosphorus and potassium balanced fertilizers are applied during the germination period, potassium dihydrogen phosphate is added during the budding period, decomposed cake fertilizer and water are applied after flowering, and fertilizer is stopped in winter. Temperature gradient control wintering and cold prevention measures When the temperature is lower than 5℃, put a double-layer plastic bag to keep the temperature warm. The surface of the basin soil is covered with 3 cm pine needles and moved to an indoor shelter at night. The over-summer cooling plan sprinkles water on the ground to cool down during high temperature periods, places ice packs around the basin, and maintains a growth environment below 30℃ through evaporative cooling. Comprehensive environmental control and air circulation management Open windows for ventilation 2-3 times a day, use circulating fans to maintain air flow, and prevent the breeding of powdery mildew and red spiders. Humidity balance tips Place bamboo charcoal bags in plum rainy season to absorb moisture, and use ultrasonic humidifiers to maintain 60% air humidity in dry season.
Through systematic maintenance and management, potted peonies can continue to bloom for 3-5 years. The key is to grasp the annual management rhythm of "protecting buds in spring, protecting leaves in summer, cultivating roots in autumn, and storing energy in winter", so that this "moving national color" can show its brilliance in every inch.
