Narcissus flowers bloom in which season
This article introduces the season when Narcissus flowers bloom and shares experience in green plant maintenance on how to save seeds. Let's learn about it together next.
As one of the traditional famous flowers in China, Narcissus is deeply loved for its fresh and elegant temperament. Its blooming period mainly focuses on winter to early spring, belonging to the typical winter ornamental flowers. This article will elaborate on the blooming season characteristics of Narcissus and the breeding and seed-saving techniques to help flower enthusiasts master scientific cultivation methods.
I. Characteristics of Narcissus flowering season
1. Natural flowering cycle: Narcissus has obvious seasonal flowering characteristics. In natural cultivation conditions, it usually blooms from January to March in the Yangtze River Valley and southern regions, while in colder northern regions, it may delay to February to April. As a perennial herbaceous plant of the Amaryllidaceae family, its flower bud differentiation requires a process of low-temperature vernalization, which is a key factor determining its winter-spring blooming feature.
2. Varietal differences: There are flowering differences among common cultivated varieties: - Chinese Narcissus (Narcissus tazetta var. chinensis) blooms from New Year's Day to the Spring Festival - Foreign Narcissus (Narcissus pseudonarcissus) flowers later, usually in March to April - Trumpet Narcissus has a flowering period between the two. By combining varieties, the ornamental period can be extended to 3 months.
3. Flowering regulation techniques: (1) Temperature control: Maintaining 12-15°C can extend the flowering period, while temperatures over 20°C will accelerate wilting. (2) Light management: 6 hours of scattered light per day is best, and direct strong light will shorten the flowering period. (3) Water adjustment: Keep the substrate moist during the bud formation stage and slightly control water after flowering.
II. Key seed-saving techniques for Narcissus
1. Bulb selection criteria: (1) Appearance characteristics: Choose robust bulbs with a circumference of over 10cm and no damage. (2) Bud status: The terminal bud is明显 swollen, and the lateral buds are evenly distributed. (3) Disease detection: Reject bulbs with brown spot disease or root mites.
2. Post-flowering bulb management: (1) Cut flowers and leave leaves: Remove withered flowers in time after they fade, and retain all leaves. (2) Fertilization plan: - Apply a phosphorus acid potassium solution (0.2% concentration) weekly - Apply mature cake fertilizer water once every half month. (3) Water control: Keep the substrate dry and slightly moist, avoiding waterlogging and rotting bulbs.
3. Ball lifting and storage: (1) Best time: Lift the bulbs when the leaves naturally turn yellow by 2/3. (2) Treatment process: ① Carefully dig out the bulbs ② Rinse with clean water and dry in the shade ③ Soak in a carbendazim solution for disinfection. (3) Storage conditions: - Temperature: 25-28°C (promotes flower bud differentiation) - Humidity: 60-65% - Environment: Ventilated and cool mesh containers.
4. Ball division propagation technique: (1) Natural division: Each mother bulb can produce 3-5 daughter bulbs annually. (2) Artificial cutting: ① Disinfect the knife and make a longitudinal cut in the bulb ② Retain 1-2芽 points per piece ③ Apply wood ash to the cut. (3) Daughter bulb cultivation: Small bulbs need to be cultivated for 2-3 years before they can bloom.
III. Cultivation precautions
1. Common problem handling: (1) Preventing flower abortion: Ensure the storage temperature meets standards to avoid insufficient vernalization. (2) Controlling etiolation: Use dwarfing agents or increase light duration. (3) Pest and disease control: Regularly spray Abamectin to control root mites.
2. Annual cultivation plan: (1) September-October: Disinfect bulbs and pot them for hydroponics. (2) November-December: Indoor care to promote flower bud development. (3) The following April-May: Field cultivation to rejuvenate bulbs.
Special note: Narcissus contains Lycorine in its entire plant. Wear gloves during handling to avoid contact with the juice on the skin. Through scientific seasonal management and standardized seed-saving techniques, continuous observation and genetic preservation of Narcissus can be achieved. Note the climatic differences in different regions and adjust the cultivation time points appropriately to obtain the best results.
