How to cultivate and manage peony
As a famous traditional flower in China, peony is deeply loved by people for its elegant and luxurious attitude. This article will explain the key points of peony planting from cultivation to maintenance system, and help you cultivate a dazzling national beauty. The core technology of peony cultivation is to select high-quality seedlings. Select strong seedlings with full bud eyes, stem and branch diameters ≥1cm, and more than 5 main roots. It is recommended to use 3-4-year-old grafted seedlings, and the development of the root system directly affects the survival rate. The best planting time for scientific planting process is from late September to early October. Burrows were dug at a plant spacing of 1.5m×1.2m, with a depth of 40cm, and 10cm of decomposed manure was laid at the bottom. Keep the root system stretched during planting, fill the soil in layers and consolidate it to form a steamed buns shaped mound with a high middle and low four sides. The key points of peony maintenance and management are precise water control and establish the principle of "three watering and three non-watering": water is poured thoroughly during the flower bud differentiation period (March to April), appropriate amount of water is poured during the bud pregnancy period (April to May), and anti-freezing water is poured before wintering (November); No watering on rainy days, no watering during dormant periods, and no watering during flowering periods. During high temperatures in summer, use foliar water spray to maintain the air humidity of about 60%. Nutritional cycle management Fertilization is divided into 4 times throughout the year: nitrogen fertilizer (15g of urea/plant) is applied during the germination period, phosphorus and potassium fertilizer (100g of bone meal/plant) is applied during the bud period, compound fertilizer is added after flowering, and organic fertilizer is applied before overwintering. Pay special attention to spraying 0.2% potassium dihydrogen phosphate solution before flowering to improve flowering quality. The systematic pruning plan implements the pruning system of "picking buds in spring, thinning branches in summer, reshaping in autumn, and clearing gardens in winter." Keep 2-3 terminal buds in spring and remove leaf buds in time; cut off residual flowers and dead branches after flowering; keep 3-5 main stems in autumn and cut off long branches; remove pest and insect branches in winter to ensure ventilation and light transmission.
Through scientific cultivation management and refined maintenance, peonies can maintain a vigorous growth trend. It is recommended to establish a maintenance log to record phenological period changes, and adjust management measures based on regional climate characteristics, so that this king of flowers can bloom with the most brilliant brilliance.
