How to Cultivate Narcissus in Hydroponics
The narcissus, with its elegant posture and fresh, subtle fragrance, has become a popular choice for winter hydroponics. Mastering scientific hydroponic methods can not only extend the blooming period but also ensure continuous reblooming of the bulbs. This article will systematically analyze the secrets of narcissus care, from light control to blooming management.
Complete Guide to Narcissus Hydroponics
Accurate Control of Light and Temperature
Ensure 6-8 hours of scattered light daily and use light curtains to filter strong noon sunlight. Monitor the ambient temperature with a thermometer, keeping it at 12-15°C during the day and lowering it to 8-10°C at night. Temperature difference control can effectively prevent excessive growth.
Key Steps in Water Management
It is recommended to use tap water that has been exposed to air for 2 days. Change the water every 2 days in the initial stage, and weekly after the roots develop. Gently wipe the root mucus with a soft brush when changing the water, and keep the water level at 1/3 of the bulb. You can use activated carbon to purify the water.
Nutrition Supply Techniques
Add 3 drops of potassium dihydrogen phosphate nutrient solution weekly during the shooting period and stop fertilizing after the flower buds show color. When using slow-release fertilizer tablets for hydroponics, place them 2cm away from the roots to avoid direct contact with the bulb.
Key Points for Ventilation and Disease Prevention
Keep the air circulation rate above 0.5m/s and use a circulation fan to assist with ventilation. Regularly spray diluted 1000 times of avermectin to prevent root mites and gray mold disease. If rot is found, immediately soak with carbendazim.
Management of Narcissus Blooming Cycle
It takes about 25-35 days from bulb treatment to blooming, and the blooming period is advanced by 3-5 days for every 5°C increase in temperature. The following measures can accurately control the blooming time: 1. Soaking in warm water (25°C) can accelerate development. 2. Moving to a 10°C environment after the flower bud formation can extend the blooming period. 3. Supplementing red light exposure can promote anthocyanin synthesis.
Hydroponic cultivation of narcissus is a process that combines scientific management and artistic aesthetics. Mastering the balance of light, temperature, and water quality, along with stage-based care measures, can not only ensure on-time blooming but also achieve a reblooming rate of over 80% per bulb. It is recommended to regularly record growth data to gradually develop a personalized care plan.
