NOVELTY - An environment-friendly vegetative cover block is prepared by fermenting organic raw materials to obtain fermented material. Embryo mutant strain is inoculated to perform fermentation and decomposition. Waste plastic pieces, pearlite, vermiculite and coal ash mixture powder, waste paper pieces, PP333 raw medicine and macromolecular water absorption material pieces are mixed with water to obtain mixed material. The mixed material is planted. The plant fibers having thickness of about 1.5-3 mm is covered. The plant fibers are crushed to have particle diameter of 3-20 mm and dried.    USE - Environment-friendly vegetative cover block. Uses include but are not limited to light raise seedling in an agriculture and forestry flower industry, treating desertification, recovering sand vegetative cover and landslide vegetative cover, greening urban ceiling and housing estate high salt ground and building football field and golf course.    ADVANTAGE - The block protects raw material resource, increases balance function of ecosystem, improves planting efficiency and provides an effective resource recycle way for municipal solid waste and agriculture and forestry wastes and organic wastes in a factory. The block optimizes and combines renewable resources to have high economic benefit and realizes effective application. The block is light in weight.    DETAILED DESCRIPTION - An environment-friendly vegetative cover block is prepared by fermenting organic raw materials to obtain fermented material. Plant degradable wastes in agriculture and forestry are crushed to obtain crushed pieces. Water is added to the crushed pieces and agitated to maintain water content of the raw materials to 50-60 percent. 500 g embryo mutant strain is inoculated in each cubic meter of the organic raw material to perform fermentation and decomposition. Substrate raw materials comprising (in weight parts) macromolecular water absorption material pieces (0.5-7.5), fermented material (60-70), waste plastic pieces (10-15), pearlite, vermiculite and coal ash mixture powder (5-10), waste paper pieces (15-20) and 95 percent paclobutrazol (PP333) raw medicine (0.25-7.5), are prepared. The waste plastic pieces, pearlite, vermiculite and coal ash mixture powder, waste paper pieces and PP333 raw medicine are added in a fermented material. Water is added and the materials are uniformly mixed. The macromolecular water absorption material pieces are added while agitating, to obtain mixed material, where dosage of water account is 50-60 percent higher than weight of the mixed material. Power of Hydrogen value is adjusted to 5.5-7.5. The mixed material is press-formed and planted. The plant fibers having thickness of about 1.5-3 mm is covered, where the plant fiber is plant piece of sweet wormwood. The plant fibers are crushed to have particle diameter of 3-20 mm and dried.
