However, the price of the main raw material turf for soilless culture is increased year by year, and the grass carbon has the defects of stable performance and low priceThe easily obtained substrate is the bottleneck limiting the development scale of the soilless culture in China. With the development of industry and agriculture in China, a large amount of organic waste is generated, most of the organic waste is not utilized and is randomly discharged into the natural environment, so that the environment is polluted, and organic resources are wasted. Many researches indicate that organic wastes such as livestock and poultry manure rotten clinker, coconut shells, sawdust, vinasse, mushroom residues, carbonized rice hulls, straws, corncobs, traditional Chinese medicine wastes and the like show certain advantages in the aspect of utilization of culture mediums. The tannery sludge has reduced toxicity after composting and decomposition, and has a great prospect in the aspect of utilization of culture medium.
