What flowers are suitable for Jinchang
Located in the middle of the Hexi Corridor, Jinchang boasts a unique temperate continental climate that nurtures a variety of drought-resistant plant landscapes. The dry, rainless, and sunlit natural environment provides ideal growing conditions for specific flower varieties. This article will systematically sort out the ornamental plants and city symbol species suitable for local cultivation.
Suitability of Jinchang's Environment and Plants
Climate Characteristics Analysis
Jinchang, with an annual precipitation of less than 200 millimeters, has significant day-night temperature differences, with a cold winter period lasting five months and frequent sandstorms in spring. This special climate requires plants to have dual properties of cold and drought resistance, with well-developed roots and tolerance to poor soil.
Preferred Flower Varieties
After years of cultivation, the following three types of plants have performed well: 1. Perennial cold-resistant plants: Lilac,珍珠梅 (Pearl梅花), Silver Leaf Chrysanthemum 2. Water-saving ornamental grasses: Red Willow, Reed, and Delicate Leaf Beauty Bush 3. Sand plants: Camel Thorns, Sand Elbow, and Flower Clubs. Among them, roses, as the city flower, have been bred to produce local varieties such as 'Jinchang Red,' with blooming periods lasting until mid-November.
Detailed Explanation of City Symbol Species
Key Points for Rose Cultivation
Choose a variety of highly productive and stress-resistant roses, and use deep hole planting (60x60 cm), mixing base fertilizer with decomposed sheep manure. Prune heavily from March to April, retaining 3-5 main branches, and spray phosphorus potassium fertilizer every half month during the growing period to enhance resistance.
Ecological Value of Chinese Scholar Tree
As the city tree, the Chinese Scholar Tree accounts for 38% of the greenery in the city, with its umbrella-shaped canopy effectively preventing wind and sand. When planting, maintain a spacing of over 5 meters, wrap young trees with anti-cold cloth in winter, and three-year-old seedlings can form complete protective functions.
Creating Unique Plant Landscapes
It is recommended to use step planting: low flowers such as Safflower and Borago in the foreground, shrubs like Forsythia and Elm Leaf Plum in the middle layer, and Chinese Scholar Trees and Poplar Trees as green barriers in the background. The rose corridor created by this method in Jinchuan Park has become a popular social media spot.
By scientifically selecting plant varieties and combining them with appropriate maintenance measures, even in the dry and rainless Jinchang, it is possible to create an ecological landscape with flowers in three seasons and greenery in all four seasons. The combination of the city flower, roses, and the city tree, Chinese Scholar Trees, has become a classic model for urban ecological construction.
