What are the繁殖 ways of narcissus?
As one of the top ten famous flowers in Chinese tradition, narcissus is deeply loved by horticulture enthusiasts for its elegant posture. Mastering the correct propagation methods can not only continue the plant's life but also experience the fun of cultivation. This article will explain the four major cultivation systems of narcissus from a practical perspective, focusing on the analysis of the application scenarios of different methods.
Core Methods of Narcissus Cultivation
Offset Bulb Propagation Method
The offset bulbs naturally formed at the base of the bulb are the most ideal propagation material. From September to November every year, when the bulbs enter the dormant period, select plump offset bulbs with a diameter of more than 2 centimeters, separate them using disinfected tools, and place them in a well-ventilated area to dry the cut surfaces. It is recommended to use a mixture of peat soil and perlite in a ratio of 3:1 as the growing medium, and the planting depth should be such that the top of the bulb is slightly exposed above the soil surface. This method has a success rate of up to 98% and is the preferred option for courtyard cultivation.
Double Scale Cultivation Technique
Professional-level propagation can adopt the double scale cutting method. Select healthy mother bulbs and cut them longitudinally into 8-12 scale units with bases, after low-temperature vernalization treatment, wrap them with moist moss and place them in a dark room at 25°C. After about 60 days, new bulbs can be seen to form. This method can achieve a single bulb expansion coefficient of up to 30 times, making it suitable for large-scale production.
Side Bud Regeneration System
The scales that fall off the bulbs during processing often contain dormant buds. After being disinfected with 0.1% potassium permanganate, they are spread flat on a vermiculite seedbed and covered with 1 centimeter of fine sand to maintain moisture. Sown in autumn, new bulbs can be obtained the following spring. This method has a high material utilization rate but a longer bulb formation period.
Tissue Culture Application
Under laboratory conditions, the apical meristem of the flower stem is inoculated on MS medium, and with the induction of 6-BA hormone, virus-free seedlings can be quickly obtained. This technology requires professional equipment support and is mainly used for the conservation of rare varieties.
Optimal Solution for Home Cultivation
Considering the difficulty of operation and success rate, the offset bulb propagation method is the most suitable for home use. Its advantages include: ① easy access to materials, ② a growth cycle of only 2 years, and ③ stable genetic traits. In practice, it is important to select陶盆 with good drainage and apply phosphorus-potassium liquid fertilizer every half month during the growing period to effectively promote bulb expansion.
Different propagation methods correspond to diverse needs from leisure horticulture to professional production. After mastering the core points, enthusiasts can choose the appropriate method according to their own conditions. It is recommended for beginners to start with offset bulb propagation, gradually trying double scale cutting, and experiencing the subtleties of narcissus cultivation in the process of practice.
