Environmental Protection
Organic coverings can not only be widely used in roadside tree planting, park scenic areas, roof greening, factory parks, courtyards, and other places, but also as substrates or decorative materials in ornamental plants such as flowers and bonsai. Especially with the rise and development of colored coverings, the application fields of organic coverings have become more extensive. They can be applied to all exposed surfaces in cities, and can effectively improve soil and beautify the environment. Including the covering and decoration of some barren soil with poor site conditions that are temporarily unsuitable for greening, the paving of urban public green garden paths and paths (to reduce the damage of hard paving to ecology), and the use of various color combinations, both ecological and environmental protection, and good landscape effects.
At present, some cities in China have begun to apply organic mulch to the soil surface under forests and shrubs. As an emerging landscape covering material, organic mulch is constantly expanding its application field in urban forestry construction in China. For roof greening and sponge city construction, it is of great significance, as water retention alone can greatly save water resources
