When Does the Scented Tree Flower
The scented tree, as an excellent species for courtyard greening and bonsai creation, often attracts the attention of gardening enthusiasts with its unique flowering characteristics. This article will systematically analyze the flowering patterns and cultivation essentials of the scented tree through scientific data and cultivation practices.
Analysis of Scented Tree Flowering Time
1.1 Natural Flowering Characteristics
In its natural growth state, the flowering period of the scented tree is concentrated in mid-to-late March every year, with a 7-10 day fluctuation between the north and south regions due to climate differences. The total flowering period lasts for 15-20 days, with an individual flower blooming cycle of about 3-5 days.
1.2 Factors Affecting Flowering
Temperature is the main regulatory factor, with flower bud differentiation initiated when spring temperatures stabilize at above 15°C. The duration of sunlight needs to reach 10 hours/day, and the soil pH value should be maintained between 6.0-7.5.
Detailed Explanation of Scented Tree Flower Shape Characteristics
2.1 Flower Color and Morphological Characteristics
Purple-red inflorescence diameter 0.8-1.2 cm, with distinct male and female flower characteristics. Male flowers have 5-8 lanceolate perianth segments, while female flowers have 2 additional ovate-lanceolate bracts.
2.2 Physiological Characteristics of Flowering
During the flowering period, the growth rate of new leaves decreases by 60%, with photosynthetic products concentrated (G-Y) in the flower organ development. The diameter of the branches where the inflorescence is located is 20%-30% thicker than that of conventional branches.
Techniques for Flowering Period Maintenance Management
3.1 Water and Fertilizer Control Plan
During the bud formation period, maintain soil moisture content at 40%-50%, alternate the application of monopotassium phosphate (0.2% solution) and decomposed bone meal (50g/m²), which can increase the number of flowers by more than 35%.
3.2 Environmental Optimization Measures
Maintain a day-night temperature difference of 8-10°C, and shading 30% during the afternoon can extend the lifespan of individual flowers. Regularly spraying chelated calcium fertilizer can enhance the toughness of the perianth segments.
By scientifically controlling environmental factors and combining precise maintenance measures, not only can the ornamental period of the scented tree be extended, but fruit development can also be promoted, laying the foundation for subsequent propagation. It is recommended that growers establish a flowering period management log to record the correspondence between phenological changes and maintenance operations.
