| Ornamental grass is a general term for many plants with ornamental value.It has a wide variety of plants,unique plant types,and rich leaf colors and textures.The development of the exploration,research and practical application of ornamental grass in my country is relatively delayed,but so far,some domestic scientific research units and enterprises and institutions have also made preliminary progress in the field of ornamental grass resource research and practical application design,and the effect Quite abundant.However,there are relatively few applied studies on ornamental grass resources in Beijing.Therefore,this thesis systematically discusses the design and application of ornamental grass as a kind of landscape grass with unique value in several representative garden landscapes in Chaoyang District,Beijing,focusing on its ornamental,adaptability and feasibility of design application.and other aspects,so that relevant enterprises,institutions and scientific research institutions can make better use of the characteristics of the development of ornamental grasses and serve the construction of gardens.The results are as follows,(1)Survey results: There are many garden parks in Chaoyang District,Beijing,including Guta Park,Beijing Olympic Forest Park,Duzhong Park,Dongjiao Yeba Park,Ritan Park,Yangshan Park,Said Park,Chaoyang Park,etc.Many wild ornamental grasses are cited in the design,such as: Liliaceae(Hosta ventricosa(Salisb.)Stearn),Hemerocallis(Hemerocallis fulva(L.)L.),Torchflower(Kniphofia uvaria(L.)Oken),sunflower(Helianthus annuus L.),black heart chrysanthemum(Rudbeckia hirta L.),dahlia(Dahlia pinnata Cav.),etc.belonging to the Compositae family.In some parks that I have investigated on the spot,there are various kinds of ornamental grasses.The main species are Gramineae,accounting for more than half,followed by Cyperaceae and Liliaceae,accounting for about one-third,and there are also Araceae,Iridaceae,rushes and other types.There are as many as 51 species of ornamental grasses in these parks.Among these species,the three kinds of ornamental grasses: Gramineae,Liliaceae and Cyperaceae accounted for more,among which Poaceae accounted for 60.3%,Liliaceae15.5% and Cyperaceae 15.5%.(2)Evaluation results: Through the investigation and research on the new varieties of ornamental grasses mainly used in the gardens of Chaoyang District,Beijing,using research methods such as data collection and on-the-spot investigation,data statistics and data analysis,and summarization and discussion in combination with actual cases,the use of ornamental grasses was evaluated.The species and adaptability were researched and discussed,and the conclusion was drawn by summarizing the evaluation: the new varieties of ornamental grasses mainly used in the garden design of Chaoyang District,Beijing are mostly exotic varieties.(3)Design results: Through the modeling of the overall garden beauty of the ornamental grasses in the public garden landscapes in Chaoyang District,as well as the research and analysis results of the resources and applications of ornamental grasses,I designed an open green space in Beijing Olympic Forest Park for the purpose of It is to use the ornamental grass with good landscape effect and suitable for local planting to better integrate the messy open green space with the surrounding environment,so that the ornamental grass can show its unique ornamental effect and better realize its development in the construction of agricultural resources.used and widely used. |
