Study On The Relativity Of Plant Landscape And Main Ecological Factors Of Rose In Harbin

In recent years, the scientific requirements for planting梔esign have been improved constantly, the research methods of planting梔esign in microcosmic degree has been paying more and more attention to. Combining with the present condition of Harbin planting梔esign, we selected Prunus tri]oba Lindl. and Rosa xanthina Lindl. , Rose rugosa Thunb. , Prunuspersica f rubro梡]ena Schneid. as the species of our study, these four species of Rosaceae are the representative plants with wide distribution and a large application in the landscape梔esign of Harbin. The relativity between the difference of landscape of these four species and their ecological conditions is studied from aspects of anatomy, ecology, physiology etc. The aim of this study is to find out the suitable ecological condition of them in planting梔esign, and to proved theoretical foundation and quantitative analysis criterion for landscape maintenance and management, and to improve scientific pianting梔esign. The results indicate that landscape effect of these four species will be better if their habitats are under sufficient light and fertile ,loose and dampish soil. But, because of the difference of interspecific among these four species, the requirements for light and other ecological factors are different. These conclusions can be used as scientific references to the planting梔esign of Harbin. We also appreciate the landscape of these four species in Harbin and put forward some scientific and reasonable modules of planting梔esign. This will bring about directive effect for practical application of planting梔esign.
