What flowers are suitable for Yinchuan
Under the protection of Helan Mountain, the unique climatic conditions of the Yinchuan Plain have created a unique plant landscape. This city on the edge of the Great Wall has both the resilience of desert plants and the refined aesthetics of artificial greening. Facing an average annual precipitation of 200 millimeters and a low temperature of 8.5℃, choosing suitable plant species is the key to creating a beautiful courtyard.
Plant selection principles under the northwestern climate
The art of balancing temperature and light
The wisdom of water-saving plants for survival
The combination of sandy soil and dry air makes native plants such as Iris lactea and Ephedra intermedia the preferred choice. These plants have leaves that are mostly leathery or densely covered with villi, which can effectively reduce water evaporation. When cultivating in the courtyard, a 5cm thick layer of gravel can be laid to reduce soil moisture loss.
Specialty flower cultivation solutions
Recommended ground planted star plants
As one of the city flowers, the purple petals of Iris lactea can form a spectacular flower carpet from May to June. Combined with varieties such as golden叶 elms and Chinese jujubes, a layered xerophytic landscape can be constructed. It is recommended to plant 15-20 Iris lactea per square meter, combined with trees spaced 3 meters apart to form a shaded area.
Overwintering management of potted plants
Southern flowers such as camellias and bougainvilleas can be grown in containers for off-site viewing. They need to be moved to a sunny indoor location in late October, maintaining a temperature above 5℃. Using a ceramic pot with a vermiculite matrix (proportion 1:3) can reduce the watering frequency by 40%.
Key points for maintaining the city's symbolic plants
Rose cultivation method in sandy soil
As another city flower, the Yinchuan rose should choose the floribunda variety. When planting, dig a 60cm deep hole and lay a 20cm layer of mixed sheep manure and sandy soil at the bottom. After flowering, prune the remaining flowers in time, retaining 3-5 main branches, which can increase the flowering amount by 200% the following year.
Technology for rejuvenating ancient pagoda trees
For national elms over 30 years old, fertilization by trunk injection is carried out before spring germination: drill three holes in a triangular shape at the base of the tree trunk, 5cm deep, and inject nutrient solution containing fulvic acid. Combined with crown reduction pruning, it can increase the amount of new branches on old trees by 60%.
In Yinchuan, a city where deserts and oases coexist, choosing the right plants and adopting scientific maintenance methods can not only create a unique courtyard landscape with the flavor of the Great Wall, but also interpret the city's ecological wisdom through the tenacious vitality of plants. By properly configuring city flowers, city trees, and other suitable varieties, every courtyard can become a miniature museum displaying the beauty of the northwestern ecosystem.
