Plant fiber blanket, preparation method and application

The invention relates to the technical field of ecological environmental protection treatment, in particular to a plant fiber blanket and a preparation method thereof.By improving a water storage layer of a traditional vegetation blanket, reasonably distributing the needling density, strictly controlling the needling depth and needling frequency and adjusting the adding amount of plant fibers, the water absorption and water retention capacity of the composite water storage layer is improved; the release of nutrients in the traditional Chinese medicine residues is effectively accelerated by combining a biological fermentation technology, the vegetation carpet taking degradable wastes as raw materials is prepared, and a new way is explored for the treatment and application of the traditional Chinese medicine residues while the degradable vegetation carpet is developed; the soil compatibility is improved, and meanwhile, the seed germination rate of the vegetation carpet is increased. The product has multiple fun
