The Study On Perennial Grass Flower Design Of Changshen Expressway-Fuxin Section In Liaoning Province

Perennial herbaceous flowers refer to ornamental plants that are still in their native habitat at present.As an important material foundation of urban landscape construction,the development and utilization of herbaceous flowers marked the level of civilized construction in a country or region.Perennial grass flowers mixed in the modern Western gardens in the rise of a herbal flower application form,with high landscape value and ecological significance,for domestic is still new things,how to build in the country requires a lot of research work.As a new type of plant collocation application,the mixed use of grass flower has a wide application prospect because of its natural landscape and low maintenance.It is of great application value in promoting conservation-oriented gardens.According to the data and case analysis,Mixed forms can be used for highway slope greening,the formation of the unique charm of the green landscape.Taking the slope of Fuxin section of Changshen expressway in Liaoning province as the research object,the main research contents in the study area are as follows:1.According to the development of highway slope greening in our country and the application research of perennial grass flower mixture at home and abroad,the necessity and feasibility of using perennial grass blending for slope greening of Fuxin section of Changshen expressway is determined.2.Through the field investigation of the research object,the current situation and limitation of plant growth of Fuxin section of Changshen expressway are determined,and the perennial grass flower selection is selected according to the limiting factors.3.Through the survival and growth of the perennial grass in the experimental area,the rationality of perennial species selection in the experimental plots was determined.According to the project research,the limiting factors affecting the perennial grass growth on the slope of the expressway were determined,and the experimental area was divided according to the restrictive factors.Based on the results,the relevant technical options were selected according to the results,and the similar afforestation projects were provided.
