How to raise buttercup in spring
As the temperature warms up, the buttercup enters a vigorous growth period. This bulbous flower, known as "foreign peony", has become the focus of spring balconies with its layered petals and colorful colors. Scientific maintenance and management can allow the buds to continue to bloom for 20-30 days, forming an amazing viewing effect. Soil improvement and root maintenance Root roots that have gone through winter dormancy are revived in spring. It is recommended to use a ratio of 5:3:2 to improve the soil. The depth of turning soil should be controlled at 15-20 cm. Keep the root roots intact during operation. A small amount of bone meal can be mixed in to increase the phosphorus and potassium content. Loose soil once a month to keep the matrix porosity at about 40%. Water control techniques during flowering period use alternating dry and wet methods during the budding period, and water is poured thoroughly after the surface 3 cm of soil is dried. High temperature weather combined with foliar spray maintains the humidity at 60%-70%. Reduce the frequency of watering after the flower buds appear to color to prevent early withered petals. Adjust the condition of the leaves by observing: replenish water when the leaves are slightly curled, and pause when they are stretched. Dynamic adjustment of light intensity provides full sunshine from March to April, and a sunshade net will be built to filter 40% of the strong light from May. The east-south balcony is guaranteed for 5 hours of direct light every day, and shade protection is needed during high temperatures at noon. Rotate the flowerpot regularly to ensure uniform light reception and prevent the plant from being biased towards growth. The nutrient supply plan is to apply nitrogen, phosphorus and potassium balanced fertilizer (10-10-10) during the germination period and dilute it to 1200 times. After budding, switch to high-phosphate fertilizer (15-30-15), combined with seaweed spray every week. Pay attention to the principle of applying thin fertilizer and frequently, and loosen the soil in time after fertilization to prevent salt accumulation and damage the root system. Extended maintenance precautions. Maintaining the temperature difference between day and night of 8-12 ° C is conducive to bright colors, and regularly checking the back of the leaves to prevent aphids. Trim residual flowers in time after flowering, and retain 1/3 of the flower stem to promote nutrient backflow. When the temperature exceeds 25 ° C, gradually reduce watering to prepare for summer dormancy.
By accurately controlling the four major elements of light, warm water and fertilizer, it can not only extend the ornamental period of buttercup, but also promote the expansion of root roots and reserve sufficient nutrients for the next year's flowering. By mastering these maintenance points, even novices can reap the beautiful spring scenery.
