How to make carnations open quickly
Carnations are a classic flower on Mother's Day, and their buds bloom speed directly affects their ornamental value. Many flower friends are often confused about how to shorten the bloom cycle of the bud, and are also worried about whether the water spray operation will affect the quality of flowering. This article systematically analyzes flower promotion techniques from five core dimensions, and focuses on answering the key points of water management during the bud stage. 1. Five rules for rapid flowering of carnations 1. Photosynthesis accelerates flower bud differentiation. Scattered light for 6-8 hours a day can improve leaf photosynthesis efficiency. It is recommended to receive direct light during morning and dusk, and use a sunshade net to filter 40% ultraviolet light at noon. Experimental data show that reasonable control of light can shorten the flower bud differentiation cycle by 3-5 days. 2. The temperature gradient control strategy maintains 22-28℃ during the day and drops to 13-15℃ at night to create temperature difference stimulation. When the temperature exceeds 35 ° C, the foliar atomization cooling method and sunshade measures can avoid the phenomenon of bud elimination. 3. The intelligent water supply management system adopts the "three-finger detection method": insert your fingers into the second knuckle of the basin soil, and pour it through when it is dry. Maintain the substrate humidity within the range of 40-50% during flowering. Excessive humidity may easily lead to root suffocation. 4. The precise nutrition supply plan applies potassium dihydrogen phosphate solution (concentration of 0.2%) every 10 days during the bud formation period, combined with organic matter such as seaweed essence. Pay attention to avoid imbalance in the ratio of nitrogen, phosphorus and potassium, and it is recommended to use type 12-24-12 slow-release fertilizer. 5. Pruning and increasing efficiency technology Keep 3-5 strong flower buds on the main branch, and remove side buds and base yellow leaves in time. Cut 1/3 of the flower stem obliquely at 45° after flowering to promote secondary flowering. Cutting tools need to be disinfected with alcohol to prevent infection. 2. Practical operation of water management during the flower bud period spray maintenance must follow the principle of "three musts and three don't": to use an atomizing spray can, operate it in the early morning, and control the air humidity at 65%-75%; do not directly spray the flower buds, do not spray in the evening, and do not spray for several consecutive days. When flowering needs to be delayed under special circumstances, spray 0.5% sucrose solution once a day in the morning and evening.
By scientifically controlling the four major elements of light, warm water, fertilizer, and timely pruning, the flowering cycle of carnations can be shortened by more than 30%. It is recommended to adjust the maintenance plan based on the actual condition of the plant and regularly check the soil EC value (preferably maintained at 1.2-1.8mS/cm) to ensure effective absorption of nutrients. Mastering these core technologies can achieve precise control of carnation buds.
