What flowers are suitable for Yufu
Under the nourishment of the subtropical monsoon climate, Yufu has formed a unique plant growth environment. The mild annual average temperature of 22.5℃ and abundant rainfall create favorable living conditions for various flowering plants. Today, we will delve into the plant code of this city, decrypting the most popular courtyard flowers and street trees.
Plant selection under subtropical climate
Four-season flowering plant guide
The annual precipitation of 1578 mm in Yufu requires growers to pay attention to the construction of drainage systems. Ground plants are recommended to choose moisture-resistant varieties: bougainvillea can bloom beautiful flowers throughout the year; the red leaves of cordyline and the white of crinum form a color contrast; combinations of lotus and water lily can create ecological pond landscapes. It is suggested to plant shallow-rooted plants such as ixora and iris on slopes, while flat areas can be cultivated with large patches of zinnia and cosmos.
Management of potted plants over winter
Winter maintenance requires attention to the regulation of day-night temperature differences, and it is recommended to use double-layer shading nets to protect evergreen shrubs such as jasmine and gardenia. For perennials like peony and chrysanthemum that require low-temperature vernalization, bulbs can be stored at 5℃ for 45 days to complete vernalization. Indoor potted plants are recommended to be equipped with an automatic irrigation system, maintaining a substrate moisture level of about 60%.
Phoenix flower special cultivation techniques
Street tree planting standards
As the city flower, the planting hole for the phoenix tree should be dug 1.5 meters square, with a 30 cm layer of gravel at the bottom. When planting, the soil ball should be kept intact, and the supporting frame should use a triangular fixing method. It is recommended to plant at intervals of 8 meters on both sides of the main roads, creating a continuous landscape corridor.
Key points of flowering period management
Before the peak flowering period from May to July, apply 20 kg of decomposed organic fertilizer per plant, combined with phosphorus-potassium compound fertilizer. After flowering, prune the remaining flowers promptly, retaining 3-5 main branches. Special attention should be paid to the control of noctuid caterpillars, using sex pheromone traps combined with biological pesticides for prevention and treatment.
Ecological value of the city tree phoenix
This tree, which can grow up to 20 meters tall, is not only a city landmark but also its umbrella-shaped canopy can reduce road surface temperatures by 3-5℃. Its well-developed root system can effectively hold soil and water, with an annual carbon sequestration capacity of 200 kg per tree. Extracts from the bark have also been proven to have antibacterial activity, reflecting a perfect unity of ecological and practical value.
From potted plants in the corner of the courtyard to the landscape strips on the main roads of the city, Yufu's plant configuration everywhere shows the harmonious coexistence of man and nature. Mastering these planting techniques can not only make the phoenix flowers bloom more beautifully but also turn the entire city into a breathing ecological gallery.
