TECHNICAL FIELD
[0001] The utility model relates to tree planting and maintenance technical field especially is related to a kind of double-substrate structure planting layer planting system for tree pool Chinese pine. BACKGROUND
[0002] In urban greening, the planting of large-specification nursery stock is of great significance to improving the quality of urban ecological environment. In paved areas such as urban roads and squares, planting pools of large-specification nursery stock have gradually become an important part of greening construction. These planting pools not only beautify the environment, but also improve the urban microclimate, providing a more comfortable living space for citizens. However, with the acceleration of urbanization, the limitations of urban soil conditions on nursery stock growth are increasingly prominent, and how to optimize the planting environment to meet the growth needs of nursery stock has become a pressing problem.
[0003] Currently, in the planting of large-specification nursery stock in urban paved areas, the following methods are commonly used to improve soil conditions: first, directly using undisturbed soil for planting without any improvement; second, partially replacing the soil by adding organic matter or sand and gravel to improve soil structure; third, setting up a simple drainage system to prevent waterlogging from causing root rot. In addition, a common practice is to lay air-permeable pipes or blind trenches to enhance soil aeration.
[0004] However, the above conventional methods have obvious defects: on the one hand, relying solely on undisturbed soil or partial soil replacement cannot meet the soil site conditions required for long-term growth of large-specification nursery stock; on the other hand, existing drainage and aeration measures often fail to effectively improve soil water exchange performance, resulting in high soil density and poor permeability in planting pools, which severely restricts the healthy development of nursery stock root systems. Therefore, how to construct a planting system that can significantly improve soil ecological function and optimize water exchange conditions has become a technical problem that needs to be solved urgently.
