Abstract

PURPOSE: To absorb and fix nutritious salts contained in water, by holding a cultivation rack unit in the water at a depth where sun light can reach, and setting an aquatic plant onto the cultivation implantion modules of said unit on land.
CONSTITUTION: An artificial cultivation ground, comprising a cultivation rack unit 1 and detacable cultivation implantation modules 2, is used. The aquatic plant can be cultivated under a good condition in the broad range of a lake, swamp, inland sea or the like where eutrophication is promoted, not only at a relatively shallower level from the shore where the aquatic plant can easily grow thick but also a deep water level where even the growth of an sinking plant would be difficult or impossible. The grown-up aquatic plant 6 is completely recovered by landing together with the module 2. The substances which the aquatic plant absorbed and fixed in its body can be completely removed on land. Thus, the effect of nutritious salts removal can be attained.
