When Does Spring Flower Bloom
As the harbinger of spring, the spring flower always blooms golden flowers ahead of the rest in the biting cold wind. This species of Oleaceae, Jasminum, not only carries people's anticipation for spring but also its unique growth habits and ornamental value are worth exploring. This article will provide a comprehensive explanation of the growth code of spring flowers, from their flowering characteristics to maintenance tips.
Analysis of the Growth Cycle of Spring Flowers
Core Blooming Period
The regular blooming period of spring flowers is concentrated in February and March, and they can open as early as after the beginning of spring. Their flowering period lasts for 40-50 days, while the wild spring flower (a variety) blooms in April. As a typical example of flowers blooming before leaves, the golden flower clusters will cover the branches before the tender leaves.
Regional Climate Influence
The specific blooming time is significantly affected by temperature gradients: in warm southern regions, it can start as early as late January, in North China, it is usually in mid-March, and in the Northeast, it is delayed until early April. A day and night temperature difference of 5-8℃ is most conducive to bud differentiation.
Analysis of the Morphological Characteristics of Spring Flowers
Flower Structure
The six-petaled star-shaped flower corolla has a diameter of about 2-3cm, with a basal tube-like structure storing nectar. The bright yellow color comes from the carotenoid deposits in the epidermal cells of the petals, while the green pigments in the sepals and the synergistic action of anthocyanins form a color contrast.
Plant Characteristics
The arch-shaped branches can reach up to 5 meters in length, with a gray-brown and smooth epidermis. The compound leaves are ovate-elliptical, with finely serrated edges. The well-developed root system can effectively anchor the soil, making it suitable for slope planting.
Secrets to Prolonging the Blooming Period of Spring Flowers
Nutritional Control Plan
Apply phosphorus-potassium fertilizer (N-P-K=5-10-10) as a top dressing before flowering, diluted 800 times and applied every half month. Supplement boron during the bud formation stage, using a 0.1% borax solution for foliar application to enhance the coloration of the flowers.
Environmental Control Technology
Maintaining a temperature of 8-15℃ can extend the blooming period of a single flower by 7-10 days. By setting up a temporary shade shelter to reduce light intensity, combined with morning and evening misting to maintain a humidity of 65%, the collective blooming period can be prolonged by about 15 days.
Mastering the phenological patterns and cultivation points of spring flowers can not only accurately predict the flowering period but also extend their blooming duration through scientific regulation. This plant, which combines ornamental value and ecological benefits, is worth promoting and applying in courtyard beautification and urban greening.
