玉渊潭公园生态花境色彩调查与分析OA

Taking the ecological flower border in the southwest of Yuyuantan Park as the research object,the species composition,flowering period,flower color and leaf color of 56 plant species were analyzed through on-site investigation and comparison with NCS A-6 1950 portable color cards.The investigation covered 27 families and 42 genera,including 11 species in the Compositae family,followed by 6 species in the La-biatae family,and 3 species each in the Scrophulariaceae,Ranunculaceae and Iridaceae families.The NCS values of the flower colors of the flowering plants were 21 standard colors,mainly concentrated in the Y-R color system.The period from late May to early July was the peak flowering stage,with plants such as Echinops bannaticus and Salvia"Pink Mammoth"having an absolute advantage,accounting for about 50%of all plants,and the ornamental effect was the best.The ornamental effect declined from late July to August,during which plants such as Canna indica and Echinacea purpurea were particularly prominent.
