Abstract:Tree planter assumes the function of protecting plants, and cleverly designed tree planter also plays an important role in shaping landscape characteristics and highlighting the environmental atmosphere. In recent years, there are some problems in the construction of urban garden tree planter in Shenzhen, such as serious homogeneity of design, poor soil environment, narrow space and so on. By analyzing the types and cases of excellent tree planters such as recreational tree planter, artistic tree planter and ecological tree planter, this paper puts forward some suggestions from the aspects of early field research, soil improvement and tree species selection, and puts forward the new technology and process of tree planter structure design based on root introduction technology, root separation technology and modular tree cavity module.
