Can daffodils be cut off?
As a popular ornamental flower in winter and spring, daffodils often trouble growers with leaf pruning problems. Reasonable leaf management can not only improve the ornamental quality of plants, but also promote flower bud differentiation. This paper will systematically analyze the scientific methods and maintenance points of pruning based on plant physiological characteristics. The biology of daffodil pruning is analyzed based on the energy supply characteristics of the bulb. The daffodil bulb stores all the nutrients needed for flowering, which determines the prunable characteristics of its leaves. Experimental data show that the complete bulb can maintain normal plant growth for 50-60 days, and even if all leaves are cut off, the flowering cycle can still be completed. Mechanism for the formation of overgrown leaves When the environmental temperature is higher than 15℃, the plant will activate the overgrown defense mechanism. Observations by the Flower Research Center of Zhejiang University found that for every 1℃ increase, leaf growth accelerated by 12%, resulting in a 30% decrease in chlorophyll content, which directly affected flower stem development. Professional pruning operation guidelines, tool selection and disinfection specifications, recommend the use of medical-grade stainless steel pruning shears, which should be soaked in 75% alcohol for 10 minutes before use. Avoid using household scissors, as insufficient closing pressure may lead to tearing of the incision. Three types of blade treatment plan 1. Sick and weak leaves: When local yellowing is found, cut at a 45° angle along the base of the leaf sheath, and apply charcoal powder to the wound to prevent bacteria. 2. Long leaves: Keep 25cm of functional leaves and 3- 5 cm of growth points at the top 3. Over-dense leaves: Cut according to the principle of "removing the inside and leaving the outside" to ensure that the scientific maintenance and environmental control points of 6-8 functional leaves per plant are maintained within 3 days after pruning, and the light is gradually increased to 6 hours per day. Use nutrient solution with EC value 1.2-1.5 to supplement, and add seaweed at a ratio of 1:800 to promote wound healing. Common misunderstandings: Avoid pruning before rain, and wounds that encounter water can easily cause soft rot. Spraying foliar fertilizer is prohibited within 2 weeks after pruning, and routine maintenance will be carried out after the new leaves are unfolded.
Through scientific pruning management, daffodils can not only maintain beautiful plant types, but also improve flowering quality. Mastering the principle of "timely and appropriate" and cooperating with precise maintenance measures can enable Fairy Lingbo to bloom in her best posture.
