Study On Landscape Application In Cassulaceae Succulents

Crassulaceae Succulent is a beautiful,exotic species with strong growth and reproductive capacity and strong adaptability.According to its growth characteristics,it can be widely applied to urban greening.Beautifying life,enriching urban species diversity and creating diversified landscapes of urban landscaping reflect the idea of building ecological civilization in China.In this paper,Guangzhou,Xiamen,Jinhua and Kunming were selected as the investigation sites,and the botanical gardens,urban parks,other green spaces,greenhouse and production and sales areas were visited in four cities,and the species and landscaping forms of the plants were recorded.In October 2015,40 kinds of common species of fleshy plants were observed for 2 years in Zhuhai,Guangdong,and their ornamental and ecological adaptability were evaluated.According to the results of the survey and the results of the experiment,we recommend the species of the plants of the family species of the family plants of the family Sedum.It provides a theoretical reference for the application of the landscape plants in the landscape plants.The main results are as follows:(1)there were 208 species of 16 genera and 16 genera of four urban Sedum plants.There were 82 species of 14 genera and 14 genera.There were 6 kinds of urban greening,6sarmentosum,Sedum sarmentosum,Sedum lineare,Sedum hispanicum,Sedum makinoi,Sedum dasyhyllum and Sedum dasyhyphyllum.There are 23 kinds of plants applied in botanical garden.There are 51 kinds of garden landscaping.There are 2 kinds of S Sedum sarmentosum and Sedum lineare in four cities.The 3 kinds are Sedum adolphli,Graptopetalum paraguayense and Graptopetalum ‘Bronze'.There are 2 kinds of wild resources Kalanchoe daigremontian hybrid and wide leaf ground root Kalanchoe daigremontiana around city or city.(2)a total of 11 genera and 167 species of common ornamental plants in Guangzhou were collected.There were 139 kinds of ornamental plants in indoor potted plants and 25 species in open field.A total of 14 families and 196 species of common ornamental plants were collected from Xiamen.There were only 170 species in indoor potted plants and 26 species in open field.A total of 187 species belonging to 14 genera and 187 species of common ornamental plants were collected from Jinhua.There were only 162 indoor ornamental plants and 25 planted in open field.There are 16 genera and 205 species of common Sedum in Kunming,including five sections of the dance Kalanchoe prolefera,the Kalanchoe orgyalis,and the Kalanchoe pinnata.79 kinds of open planting are the most cultivated species in four cities,and the most open planted species.(3)in the experiment,9 kinds of V grade plants with the best comprehensive evaluation grade were selected,namely,Graptopetalum ‘Bronze',Graptopetalum paraguayense,Sedum adolphli,Graptosedum ‘Francesco Baldi',Kalanchoe marmorata,Kalanchoe daigremontian hybrid,Crassula portulacea,and Graptopetalum mendozae and Graptopetalum ‘Mirinae'.5 kinds of IV grade plants are evaluated,which are Sedum super‘Burros',Echeveria runyonii,Echeveria huthspinke,Pachyphytum oviferum ‘Pachytoides',and Pachyphytum ‘Doctor Comelius'.It is suggested that it should be popularized in Zhuhai and surrounding cities.(4)it is suggested that there are 9 species of Sedum in landscape landscaping,which are the Crassula portulacea,Sedum adolphli,Echeveria huthspinke,Echeveria runyonii,Graptopetalum paraguayense,Graptopetalum ‘Bronze',Graptosedum ‘Francesco Baldi',Graptopetalum ‘Mirinae' and Graptopetalum mendozae.(5)there are some problems in the application of the fleshy plants in the garden in China: the application of native plants is less,the application types and forms are single,the vast majority of the species depend on the import;some kinds of outdoor cultivation,but no unified cultivation and production standards,the lack of independent research types;laws and regulations need to be improved.It is suggested to strengthen the development and utilization of the local edible plants of the family Sedum,develop new species with independent intellectual property rights,and strengthen the research on the rapid propagation technology of fine varieties.According to the raw nature,domesticability and strong resistance of the plants of the scolium,we try to recommend the use of scolium meaty plants to the desert,desert,semidesert and high alpine regions in China,and to explore the development of the ecological diversity of the plants of scolium.
