Abstract:

In order to explore the diversity and current situation of ornamental plants in the Rare Tree Species Exhibition Garden of Qingxiu Mountain, and provide scientific basis and reference for the later landscape construction and management, the diversity of ornamental plants in the Rare Tree Species Exhibition Garden of Qingxiu Mountain was comprehensively investigated and analyzed. The results showed that there were 364 species of flower-viewing plants in 95 families, 255 genera, and 308 species of fruit-viewing plants in 89 families, 211 genera. Among them, 133 genera were only used for flower viewing, 89 genera were only used for fruit viewing, and 122 genera were used for both ornamental types. At the level of family, genus and species, white flower plants accounted for the highest proportion (28.06%, 35.38%, 38.10%), followed by yellow flower, red flower, green flower and purple flower, and orange flower and blue flower accounted for a relatively low proportion. The overall flowering period was concentrated in April to June, and the fruiting period was concentrated in August to October, with obvious seasonal characteristics. There are many species of flowering plants in spring and summer in Qingxiu Mountain Rare Tree Species Exhibition Garden, and the color of flower landscape is mainly determined by five color systems: white, yellow, purple, red and green. Although the ornamental features are obvious, there are still some specific characteristics, such as small proportion of gymnosperms, unbalanced composition of color systems, scattered plant communities, and insufficient ornamental effect in winter. It is suggested to increase the use of gymnosperms, appropriately increase the species of flower-viewing plants in pink, orange and blue color systems, build a flower landscape with dominant families as the main community, and appropriately supplement the species of flower-viewing plants in winter, so as to give full play to the characteristics of flower and fruit viewing, and achieve the effect of landscape in all seasons.
