CULTURE MEDIUM FOR ROOT CULTURE IN CULTURE SOLUTION, DURING LEVEL DOWN AND IN MOISTURE

摘要

PURPOSE:To obtain the title culture medium with the feed of nutrient ensured to be kept appropriate at all times, by making a fertilizer-formulated culture solution penetrate into or adsorb on granulated carbonized product. CONSTITUTION:A conventionally used fertilizer is adsorbed on or penetrated into a granulated carbonized product consisting of activated carbon of rice hulls or woodchips origin. Said granulated carbon product is then put into a container 5 with many holes on its sides. During culture, the fertilizer is gradually percolated, ensuring the feed of nutrient to be kept appropriate at all times. If the nutrient in the culture solution is excessive, the culture medium (i.e. granulated carbonized product) will absorb it; on the other hand, in case the nutrient is deficient, said medium will release it, thus effecting favorable plant growth.
