Daphne blossoms several times a year
As one of the famous traditional flowers in China, Daphne is deeply loved for its elegant aroma and unique flower appearance. This evergreen shrub not only has ornamental value, but also attracts the attention of gardening enthusiasts due to its special flowering habits. Its flowering period is closely related to daily maintenance, and the effect of extending the viewing period can be achieved through scientific management. Basic rules of flowering period of Daphne odora, natural growth cycle characteristics. Under the natural growth state, Daphne odora follows the biological rhythm of "blooming once a year". A flower bud is formed in November every autumn. After winter dormancy, it will usher in its full bloom from March to April of the following year. This seasonal flowering mechanism is closely related to the climate characteristics of its origin. Climate and environmental impacts show that temperature changes have a significant regulatory effect on flowering: 1. Continued low temperatures (<5℃) will delay flowering by 2-3 weeks 2. When the temperature difference between day and night reaches 8℃, flower bud differentiation accelerates 3. Extreme cold waves may cause frostbite and shedding of flower buds. Analysis of flower morphological characteristics Typical appearance characteristics Daphne inflorescences are capital-shaped and terminal, the outer petals are light purplish red and transition to the inner fleshy red. The calyx tube is 6-10mm long and has villous. The pistil structure is precise. The stamens and anthers are arranged in an oval shape at 2 mm. Special variety differences The petals of the Daphne var. Phnom Penh var have golden yellow edges, the white Daphne var is pure white, and the hairy Daphne calyx tube is densely covered with gray-yellow silk hair. There is a 7-15-day difference in the flowering period of each variety. Scientific post-flowering management plan Precise pruning technology The residual flowers and the top 5 cm of flower stems should be cut off immediately after flowering, and the base 3-4 bud points should be retained. Use disinfectant scissors to trim at a 45° angle, and apply plant ash to the incision to prevent infection. Regeneration and reproduction techniques Select semi-lignified branches for cuttage: 1. Retain 2-3 leaves to reduce transpiration 2. The substrate is perlite: vermiculite =1:1 mixed 3. Maintaining 85% air humidity and promoting roots in an environment of 25 ° C can achieve an extension of flowering by 30-45 days through scientific control of temperature, light and water and fertilizer management. Regularly turn the pot to ensure uniform light reception, apply phosphorus and potassium fertilizers to enhance stress resistance, and combine with moderate water control to stimulate flower bud differentiation, making this "auspicious sign in flowers" bloom more lasting charm.
