Advantages of using ecological bags for slope protection

　　With the rapid development of China's economic construction, the greening and beautification of mining areas and road slopes have become an important aspect of economic construction.

　　In many engineering constructions, vegetation damage and soil erosion are becoming increasingly serious. The application of ecological bag masonry in slope stabilization and greening is effective, and the laying of ecological bags is simple, easy to operate, and has low costs, making it suitable for large-scale application and promotion.

　　When using ecological bags for greening and slope protection, the slope surface should be leveled first, debris such as stones and branches should be cleared, and potholes should be filled and compacted with soil. Before laying, cover the slope with a layer of approximately 10 cm to 15 cm thick base soil to promote the deep penetration of grass roots, make the bottom of the ecological bag closely contact the base surface, reduce the exposed area of the planting bag surface, achieve the effect of maintaining water and preventing soil erosion.

　　Crop soil is also used as mature soil for ecological bags. If there is no crop soil available, raw soil can be added with some peat soil, plant ash, fertilizers, water retaining agents, etc. If the soil is too sticky, some fine sand can be added.

　　During the spring, summer, or early autumn seasons, after construction, water the ecological bag continuously for more than fifteen days until all the plant seedlings emerge. Gradually reduce the interval between watering, and after about thirty days, the grass is basically flat and can be maintained like a normal lawn.

　　If construction is in late autumn or winter, do not water the ecological bag again to prevent the grass seeds from freezing to death before they have just sprouted and the roots have penetrated deep, which will affect the next year's green growth.
