| Mixed planting of compound flowers is a newly emerging application form of flowers.The combination of herbaceous plants which is mainly composed of perennial flowers and mixed flowers,and it is characterized by the rich species,relatively lasting landscape,low conservation as well as low cost.It meets the development needs of ecological garden and conservation garden,so it has a broad development prospect.However,nowadays,most of the similar studies in China are limited to the concept of mixed planting combination,historical evolution and other aspects,and lacking of the research on the rules of establishment and dynamic evolution of landscape.Based on the investigation and research,combined with the experiment and practice of mixed planting combination,this paper tries to screen the hybrid planting combinations and plants with suitable relatively stong resistance,relatively long flowering period and relatively good appreciation in the Yangtze River Delta region to provide the reference for similar research and practice.The main results are as follows:(1)Systematically combing the literature about the combination of mixed planting flowers both at home and abroad,and analyzing the application form of mixed planting flowers from the aspects of plant material selection,combination design and so on.The color composition,seasonal changes and environmental impact factors were also discussed.The idea and practice of mixed planting flower combination has been relatively mature in Europe and America,and has created many classic cases,which is worthy of domestic study.(2)With the attitude of learning from nature,the original wild flower meadow in Inner Mongolia was investigated,and the plant species composition of herbaceous community was analyzed.Field investigation on the application of grass flowers in Yangtze River Delta and Southwest China was carried out,including the flower sea and plant combination landscape in all kinds of gardens.The analysis showed that there were some problems such as homogenization of landscape effect,single selection of varieties,short viewing period and so on in the present form of flower and sea.It was suggested that the trend of future development should be gradually changed from a single landscape of flowers and seas to a complex perennial plant landscape,that is,garden form,and the construction of a compound mixed planting plant combination was a valuable part of it.(3)Taking the inspiration from the meadow natural habitat,the mixed planting combination experiment was carried out under the condition of roof and open field,and the mixed planting combination with good growth condition and good overall landscape effect was observed and screened.(The specific combination methodof the combination with a better effect should be explained)and the mixed planting form will be applied in the lawn establishment,carries on the low maintenance type to affix the grass blanket the attempt and the practice.(4)Mix planting combination in Zhejiang Shangyu "Sea Flower Field" scenic spot optimization design,Pizhou North Huahai design for practical use.In order to enhance the sustainability of landscape,construct herbaceous community and increase the application frequency of perennial plants,the rational mixed-planting combination of perennial flowers with strong resistance and wild beauty was put forward in order to enhance the sustainability of landscape,construct herbaceous community and increase the application frequency of perennial plants.In order to realize the effect of enriching plant diversity and prolong the ornamental period,it can provide some reference for the construction of herbaceous plant landscape. |
