VEGETATION MAINTENANCE SYSTEM

A vegetation maintenance system includes a permeable kerb (10), a water-diversion layer (30), a water-storage layer (50), a nutrient layer (70), and a vegetation-planting trough (90). The permeable kerb (10) is disposed at at least one side of a road in a road direction. The water-diversion layer (30) is located on a side surface of the permeable kerb (10) and is disposed close to a bottom of the permeable kerb (10). The water-storage layer (50) is disposed at one side of the water-diversion layer (30) away from a surface of the road, and is configured to store water. The nutrient layer (70) is disposed at one side of the water-storage layer (50) away from the water-diversion layer (30), and is configured to provide water, soil, and nutrients for growth of vegetation. The vegetation-planting trough (90) penetrates through the water-diversion layer (30) and the water-storage layer (50), is embedded in the nutrient layer (70), and is configured for vegetation planting. The vegetation maintenance system can simulate a natural water cycle pathway of "natural rainfall, nourishing plants from top to bottom", such that healthy growth of the plants in urban environment is ensured. In the meanwhile, rainwater can be fully utilized to irrigate the vegetation, such that labour costs are reduced, and accumulated water on the surface of the road and a flood-waterlogging damage can be prevented effectively.
