THE CULTURE SOIL FORMED BY WOOD PELLET AND THE PROCESS OF MANUFACTURE THEREOF

摘要

PURPOSE: Wood pellet type culture soil, and a producing method thereof are provided to offer abundant amount of minerals and excellent water-retaining capacity to the culture soil. CONSTITUTION: A producing method of wood pellet type culture soil comprises the following steps: crushing wood to obtain sawdust(10S); drying the crushed sawdust(20S); mixing the sawdust with a mineral agent extracted from a medium containing inorganic metal salt using the microbial population before or after drying the sawdust(100S); and compressing the sawdust mixture, and cutting the sawdust into pellets(30S). The mineral agent is obtained by the following steps: proliferating photosynthetic bacteria; and dipping the medium containing the inorganic metal salt into the microbial population capable of stabilizing the photosynthetic bacteria for ionizing the inorganic metal salt.
