How often does Narcissus change water?
As a traditional New Year flower in China, narcissus have become a popular choice for indoor cultivation in winter due to their elegant flower appearance. During the maintenance process of hydroponics narcissus, scientific water change and fine management are the keys to cultivating healthy plants. This article will comprehensively analyze the key points of maintenance from basic operations to advanced skills. In the early stage of water change cycle management, the water needs to be changed every day when the bulbs are first put into the hydroponic container. It is recommended to adopt a cycle of adding in the morning and pouring in the late: inject clear water from 8-9 in the morning, and thoroughly invert the container from 20-21 at night to drain the water., repeat the operation the next day. This stage lasts for 7-10 days and can effectively activate root development. The flower bud differentiation period is adjusted. When the stem stretches to 5 cm, the bud pregnancy period will enter, and the water change frequency will be adjusted to 2-3 days per time. When changing water, 1/3 of the original solution will be retained to maintain microbial balance. Experimental data shows that moderately reducing the frequency of water changes can increase the flowering rate by 28%. Dormancy period maintenance After flowers fade, the summer dormancy period can be extended to 5-7 days to change water, but it needs to be added in conjunction with the addition of 0.1% carbendazim solution to prevent root rot. Be careful to keep the water level 1 cm lower than the bulb to avoid the bulb from rotting in water. The light control plan of the Narcissus refined maintenance system ensures 6 hours of scattered light every day, and uses an illuminance meter to monitor and maintain the range of 2000-3000Lux. At noon, 30% of the light needs to be blocked to prevent leaf burns, and at night, plant fill light can be added for 2 hours to promote nutrient accumulation. The container selection standard recommends using a shallow ceramic basin with a diameter of 15-20cm, and the oxygen permeability of the material should be>15mg/m²·h. The specially designed annular bracket container can effectively fix the bulb and increase the root stretch area by 40%. Coordinated control of temperature and humidity keeps the temperature difference between day and night within the range of 5℃, with 12-15℃ during the day and 8-10℃ at night being the most appropriate. Combined with hygrometer monitoring, when the air humidity is 55%-65%, an ultrasonic humidifier can be placed to operate intermittently within 1 meter. The plant pruning process uses a 45° oblique shearing method to treat the aged roots and retain 8-10cm of healthy roots. Leaf pruning follows the principle of "removing three and leaving two": retaining two functional leaves for each plant, removing long leaves exceeding 25cm in time, and applying plant ash to the incision for corrosion prevention.
Through systematic maintenance and management, Narcissus can not only extend the flowering period to 30-45 days, but also achieve the rejuvenation of the seed balls. It is recommended to combine regular observation and records to establish a personalized maintenance log to gradually grasp the delicate balance of daffodils growth. When the leaves show emerald luster and the buds are full and stand upright, it is the best reward for careful maintenance.
