What principles should be followed when planting landscape plants?
Landscape plants occupy a very important position in garden design, and the quality of plant arrangement affects the quality of the garden landscape and the performance of its functions. What are the principles of landscape plant planting?
Principles of landscape plant planting
1. Meet the nature and functional requirements of the green space
The nature and functions of garden green space determine the selection of plants and the planting forms. Garden green space has many functions, but a specific green space always has its specific main function. For example, the main function of street green space is to provide shade and organize traffic, so planting focuses on solving the problems of shade, traffic and aesthetics.
2. Meet the needs of garden landscape composition
Formal garden layouts mostly adopt formal arrangement forms, with planting as opposite planting, row planting, central planting, flower beds and formal flower terraces, and plants are shaped and pruned. In natural-style garden green spaces, asymmetrical natural-style planting is used, fully expressing the natural posture of plants, with arrangement forms such as specimen planting, clump planting, mass planting, woodland, flower clusters, flower borders and flower strips. People have requirements for appreciating plant scenery in many aspects, and all-purpose garden plants are very few, or rather nonexistent. Therefore, when arranging plants, reasonable combinations should be made according to their ornamental characteristics, showing the comprehensive effect of plants in form, color, scent and sound.
The arrangement of different plant proportions affects the changes in the layers, colors, seasonal aspects, space and see-through scenery forms of the plant landscape, as well as the stability of the plant landscape. Therefore, in tree arrangement, the proportions of fast-growing trees and long-lived trees; trees and shrubs; foliage plants and flowering plants, as well as trees, flowers, lawns and ground cover plants, should be appropriate. In plant planting design, the appropriate proportions among trees, flowers and grasses should be determined according to different purposes and specific conditions. For example, in commemorative gardens, the proportion of evergreen trees and coniferous trees can be larger; in courtyards, more flowering trees can be used.
3. Meet the ecological requirements of plants
To meet the ecological requirements of plants and enable them to grow normally, on the one hand, it is necessary to adapt to local conditions so that the ecological habits of plants and the ecological conditions of the planting site are basically unified. On the other hand, it is necessary to create suitable ecological conditions for the normal growth of plants; only in this way can the plants survive and grow normally.
4. Reflect national style and local characteristics
Gardens in China and gardens in various localities have many traditional plant arrangement forms and planting preferences, forming certain arrangement patterns. They should be flexibly applied in garden landscaping.
The planting of landscape plants needs to be carried out according to local actual conditions, adapting to local conditions, with scientific management and arrangement, so as to produce better results.
