Cultivation method of water-cultured daffodils
Daffodils are deeply loved for their elegant flower appearance and refreshing fragrance, and the hydroponics method perfectly displays the beauty of their roots. However, in actual maintenance, details such as water change frequency and ball handling often trouble flower friends. This article will analyze in detail the key skills of the entire hydroponics process to help you easily cultivate slim daffodils. 1. Pretreatment specifications for basic operation of narcissus hydroponic seed balls Select plump seed balls without mildew spots, use a disinfectant blade to cut the outer layer of brown scales, and retain the milky white new bulbs. When pruning residual roots, leave the base plate intact, apply carbendazim powder to the wound, and place it in a cool and ventilated place to dry for 24 hours to form a protective film to prevent hydroponics and rot. Water quality selection and treatment Use RO purified water or tap water dried for 3 days, and the chlorine content in the water must be <0.5mg/L. It is recommended to equip a TDS test pen to control the water quality between 30-50ppm. An activated carbon filter layer can be added to the water to effectively absorb impurities and maintain clear water quality. 2. Advanced skills for changing water for daffodils at different stages Water changing strategies During the non-rooting period (the first 7 days), change water every day and clean the inner wall of the container. The water level immerses 1/3 of the bulb. After rooting, the stable period is transferred to the "semi-water exchange method" is used: 2/3 of the water volume is changed every week, and part of the stock solution is retained to maintain microbial balance. Ten days before flowering, potassium dihydrogen phosphate (concentration of 0.1%) was added when changing water to promote flower bud differentiation. Scientific ratio of nutrient solution When changing water, add special nutrient solution for hydroponics and dilute it at a ratio of 1:1000. It is recommended that the N-P-K ratio be 3-6-6, supplemented once a week. Note that the water temperature needs to be consistent with the ambient temperature, and the temperature difference should be controlled within ±2℃ to avoid root stress. 3. Control the growth environment of daffodils and coordinate management of light and temperature to maintain daily light for 4-6 hours. Use the combination of "scattered light + direct light": receive direct light before 10 a.m., and use sunshade nets to filter strong light at noon. The temperature difference between day and night is controlled at 8-10℃ (18-22℃ during the day and 10-12℃ at night), which can effectively prevent excessive leaf growth. The air circulation system is equipped with a micro circulation fan, which is turned on regularly three times a day, forming air convection for 30 minutes each time. Keep the environmental humidity at 60-70%, and avoid direct spraying from the leaves when using ultrasonic humidifiers. Regularly wipe the air root area with an alcohol cotton pad to prevent the growth of mold.
By accurately controlling the water changing rhythm and maintenance parameters, daffodils can maintain a viewing period of 45-60 days. It is recommended to establish a maintenance log to record the time of each water change, nutrient solution ratio and environmental parameters, and gradually form a personalized maintenance plan. Mastering these core technologies, your daffodils will surely bloom in the most moving posture.
