What flowers are suitable for Hulunbuir
In the unique topography of the vast Hulunbuir grasslands and forests, flower planting must adapt to the severe cold climate and showcase ecological characteristics. What kind of plants can this fertile soil in the northern frontier cultivate? How should the local representative city flowers and trees be cared for? Let's explore the answers through three dimensions.
Plant survival rules in cold climate
The dual challenge of temperature change
The extreme temperature difference of -5°C to 3°C annually requires plants to have both cold and drought resistance. The long frost period of up to 7 months makes it difficult for ordinary flowers to survive the winter, but perennial plants like Dianthus and Peony can hibernate at -30°C and germinate again the following year.
Special needs of light and soil
The advantage of 2800 hours of annual sunlight allows sun-loving plants like Rhododendron and Forsythia to grow strong. The improvement method of mixing humus into sandy soil has successfully cultivated ornamental shrubs like Lilac and Hibiscus.
Guide to special flower planting
Preferred list of ground plants
From the wild domesticated Lilliput to the introduced improved Trumpet Creeper, more than 30 kinds of cold-resistant flowers form a gradient planting plan: the Early Spring Xing'an Rhododendron (city flower) and the Late Autumn Scabiosa take turns blooming, combined with the evergreen background of Zhalin Pine (city tree) to create a four-season landscape belt.
Key points of indoor potted plant care
Indoor plants like Epipremnum and Snake Plant should note: maintain 50% air humidity during the winter heating period, use ceramic pots combined with peat soil as a substrate, and apply phosphorus and potassium fertilizer monthly to enhance stress resistance.
Ecological code of city flowers and trees
Propagation techniques of Xing'an Rhododendron
When propagating the city flower by cutting, select semi-woody branches, soak them in root powder, and cultivate them in a matrix of decayed leaf soil and river sand in a ratio of 3:1. Prune promptly after flowering and divide every three years to maintain growth vitality.
Key points for cultivating Zhalin Pine
Build windbreaks for seedlings of the city tree, and control water using drip irrigation. For plants over five years old, thinning and pruning are carried out to maintain a natural pyramidal crown, and the trunk is coated with white in winter to prevent frost cracking.
Through scientific selection and careful care, Hulunbuir can not only cultivate more than 300 special plants but also make the city flowers and trees become an ecological business card. This planting wisdom that adapts to local conditions is creating a unique garden aesthetic system in the north.
