Analysis of Heyuan's Climate Characteristics
Temperature and Humidity Conditions
An average annual temperature of 21℃ combined with 1742mm of rainfall creates a typical humid and hot climate. The concentration of 78% of the annual rainfall from April to September requires plants to have waterlogging tolerance.
Distribution of Sunlight Resources
The annual sunshine hours of 1733 exceed those of the same latitude areas, providing an ideal growth environment for long-day plants, but attention should be paid to protection from strong sunlight in summer.
Selection of Suitable Flowers for Heyuan
Recommended Ground Plant Varieties
Species such as cosmos and impatiens perform well in wet conditions, with the Chinese rose (trachelospermum jasminoides) blooming for over 300 days a year. It is recommended to set a 30cm drainage layer to deal with seasonal waterlogging.
Potted Plant Management Techniques
Woody plants like jasmine and osmanthus are recommended to be cultivated in ceramic pots, with 50% shade netting used during the rainy season to control sunlight. No indoor transfer is needed in winter, but nitrogen fertilizer should be stopped.
Ecological Value of City Flower and Tree
Application of Chinese Rose (Trachelospermum jasminoides) Landscape
As the city flower, the Chinese rose is suitable for creating vertical greenery, with a single plant covering an area of up to 15 square meters, effectively reducing the surface temperature of buildings by 3-5℃.
Ecological Function of Camphor Tree
The phytoncides released by the camphor tree have a natural antibacterial effect, with a daily carbon sequestration of 12kg per tree, making it a core species for building urban ecological barriers.
By scientifically selecting suitable plant species, Heyuan residents can create an ecological courtyard with flowers all year round. The combination of Chinese rose and camphor tree applications not only highlights the city's characteristics but also improves the quality of the living environment.
