What are the advantages of the greening construction with three-dimensional vegetation nets?

Effective Soil and Water Conservation: The three - dimensional vegetation net has a loose and soft texture, with 90% of its space available for soil filling. Before the vegetation forms a turf, it can effectively prevent soil erosion, protecting the slope surface from being eroded by wind, rain, and floods. Its surface is uneven, which can create small vortices in the wind and water flow, buffering and dissipating energy, reducing the flow velocity, and thus effectively resisting the scouring of rainwater. In addition, the filling materials in the net bags, such as soil particles, fertilizers, and plant seeds, are well - fixed and less likely to be lost due to rain erosion.

Enhanced Slope Stability: The three - dimensional vegetation net can enhance the shallow - layer protection of the slope. Its grass and shrub root systems are connected to the net ribs, forming a plate - like structure, which increases the anti - tension and anti - shear strength of the protective layer, restricts the expansion of "progressive failure" caused by erosion, and ultimately prevents the occurrence of shallow - layer sliding and uplift on the slope surface.

Promotion of Plant Growth: The three - dimensional vegetation net can firmly protect the grass seeds, evenly distributing them on the slope surface. It provides a comfortable, neat, and balanced growth environment for plant roots, allowing the roots to pass through the concave - convex net bags and better combine with the slope soil. Moreover, it can reduce the evaporation of soil moisture on the slope and increase the infiltration amount, creating good conditions for plant growth.

Beautification of the Environment: After the grass seeds germinate and grow, they can form a green coverage, which can effectively cover the bare slope surface, improving the overall environment and achieving the effect of landscaping. This is especially important for areas with high landscape requirements, such as scenic roads and suburban parks.

Low - Cost Construction: The construction technology of three - dimensional vegetation nets is simple, with a short construction period and low cost. Compared with traditional masonry protection methods, it has smaller engineering quantities and lower costs while achieving good protection and greening effects.

Good Adaptability: The three - dimensional vegetation net is made of environmentally friendly polymer materials such as polyethylene and polypropylene, which have the characteristics of ultraviolet resistance and corrosion resistance, and have good adaptability to different natural environments. At the same time, by selecting appropriate grass seeds, it can adapt to the climatic conditions of different regions.
