Study On Rosaceae Plants In Xining City And Their Application In L Andscaping

There are many species of rose plants,strong ornamental,good landscape effects and strong adaptability.Therefore,there are more and more widely used gardens.Not only gardening designers,but also popular among the general public.However,because of the lack of understanding of the physiological and ecological habits of the Rosaceae plants,it leads to the poor growth of plants,less flowering,poor ornamental and poor landscape effect in the application process.Such research is conducive to better application of Rosaceae plants,in order to improve the landscape effect of Rosaceae plants in green space.On the basis of literature review,this study carried out a field survey on the Rosaceae plants used in landscape greening in Xining,and measured the physiological and ecological characteristics of common Rosaceae plants.The following main conclusions were drawn:The application status of Rosaceae plants in representative parks,residential areas and road green spaces in Xining was surveyed.The results show that there are 15 species of Rosaceae in Xining,3 species of Photinia,2 species of apple,papaya and Rosa,and 8 species of plum,and only 1 species of Pyrus.The survey shows that Rosaceae plants are widely used in parks and greenbelts,and the application types and application modes of green plants and road green spaces in residential areas are few.At present,the most widely used plant gardens in Xining are red leaf plum,Begonia,Prunus Prunus,cherry blossoms and other cherry blossoms,modern Chinese rose,Huang Cimei,rose and so on.Through the analysis,there are some shortcomings in the application of the Rosaceae plants in Xining,the first is that the landscape level of the road greening plants is not rich enough,and the maintenance management is not in place again.Finally,the physiological and ecological habits of the Rosaceae plants are not paid enough attention.The light curves,A-Ci curves and fluorescence parameters of several Rosaceae plants were also determined.Through curve fitting and calculation,the light saturation point,light compensation point,maximum photosynthetic rate,maximum respiration rate,maximum electron transport rate,optical compensation point and saturation point of each plant are obtained.The results show that the plants of Rosaceae,which are below the saturation point,are Begonia,elm,plum and papaya.These plants grow well under the shade of trees or in the shade,and have strong ornamental and strong resistance to diseases and insect pests.The Rosaceae plants with light saturation point are purple leaf plum,Shi Nan,and Yu Li.These are strong positive plants and can adapt to the strong light environment,but strong light with high temperature can also slow the growth of these plants.Other measurements showed that Rosaceae plants could adapt to the strong light and high temperature environment in Xining without water stress.According to the analysis,the following suggestions are put forward to use the native tree species as the skeleton,to adapt to the different landscaping characteristics of the Rosaceae plants,to combine the function and ornamentals,to highlight the urban characteristics according to the different environment,and to master the appropriate proportion of the deciduous tree and the evergreen tree.In the early stage of plant design,it is of practical significance to take full consideration of plant growth characteristics to strengthen the maintenance and management of trees,and to promote scientific maintenance methods.
