What flowers are suitable for cultivation in Haixi
Haixi Prefecture, located in the heart of the Qinghai-Tibet Plateau, boasts unique climatic conditions that give birth to distinctive plant landscapes. The harsh environment of high altitude and arid climate makes flower cultivation challenging, yet it is this extreme climate that has created a collection of highly ornamental plants.
The impact of highland climate on plant growth
Sunlight and temperature difference characteristics
With over 3000 hours of abundant sunlight annually and a temperature difference of more than 15 degrees between day and night, this environment creates unique advantages for photosynthesis and nutrient accumulation in plants. This type of environment is particularly suitable for flowers with high anthocyanin content, such as lilacs and gentians, which will display more vibrant colors.
Pattern of precipitation distribution
The precipitation pattern concentrated in summer requires plants to have the ability to grow rapidly, and native wildflowers like Stellera chamaejasme can complete their entire life cycle during the rainy season. It is recommended to use deep-rooted containers for planting, combined with water-retaining substrates to enhance drought resistance.
Practices of cultivating characteristic plants
Optimal varieties for courtyard landscapes
Khaisan flowers (eight-petal plum) have become the top choice with their blooming period of up to four months. Planting golden cosmos and snake's-tail flowers together can create a staggered ornamental层次. Cold-resistant shrubs like rosehip can be used as windbreak hedges, and their orange-red berries attract birds in winter, adding vitality.
Indoor potted plant care techniques
Choose a breathable volcanic rock substrate and control the amount of watering to prevent root rot. Magnolia flowers require vernalization to bloom and can be placed on unenclosed balconies in winter to meet the low-temperature requirements. crabapple类 plants need to be regularly rotated to maintain a symmetrical plant shape.
Ecological value of representative plants
Unique advantages of the city flower, red willow
As the city flower of Geermu, the red willow's roots can reach 10 meters underground to absorb water, and its leaf salt glands have the function of excreting salt. In spring, its pink flower spikes form a spectacular landscape, and its branches are highly flexible and can be used for windbreak and sand fixation projects.
Pioneer species for ecological restoration
Fireweed improves the soil by secreting allelopathic substances, and the fibrous roots of Pedicularis can effectively stabilize flowing sand. These plants, while maintaining soil and water, create living conditions for the migration of other species.
Practicing horticulture in the unique environment of the plateau is both a technical challenge and an ecological exploration. Choosing suitable species and simulating the natural community structure can not only create characteristic landscapes but also maintain the balance of the fragile plateau ecosystem.
