FUNCTIONALITY BED SOIL AND IT'S METHOD OF MANUFACTURING

摘要

PURPOSE: Functional bed soil and a producing method thereof are provided to prevent the decay of roots planted in the bed soil after supplying massive amount of water. CONSTITUTION: A producing method of functional bed soil comprises the following steps: dipping one material selected from perlite, volcanic stones, or glass foam in water; spreading inorganic mineral powder on sediments obtained from the previous step for coating the surface; naturally drying the coated surface of the sediments in a windy space with sunlight for 2-4 hours; plasticizing the material inside the coated surface at 800-1,000 deg C to obtain lightweight ceramic; and mixing 5-30wt% of lightweight ceramic, 40-80wt% of organic matter, 10-20wt% of organic mixture, and 5-30wt% of inorganic matter.
