Introduction to environmentally friendly coconut velvet blanket: A kind of beige mesh covering - coconut velvet blanket - can be seen in the drainage ditch of the Olympic Forest Park and on the shore of the main lake. It is all made of broken coconut shells. It can not only prevent soil erosion to a large extent, but also assist the rainwater collection system in draining water into the lake. In addition, after a period of weathering, this kind of coconut fleece blanket can naturally degrade into fertilizer to maintain the land and plants, and promote the root growth of green vegetation on the lake shore.
