Fertilizer components such as nitrogen and phosphate are included in water of rivers and streams. For the above reason, the temperature of water in rivers and streams rises in the summer season, leading to massive proliferation of green algae. For the above reason, roots of aquatic plants (6) absorb nitrogen, phosphate, etc., which are dissolved in water, and purify the water quality. Hydrophilic aquatic plants (6) include lotus, water lily, rice, reed, orchid, cattail, Korsakow's monochoria, sheathed monochoria, water parsley, Marsh dayflower, etc. A rope (5), a buoy (7), and a net (8) are installed in a culture area (4) of an aquatic plant hydroculture facility (1) for preventing proliferation of green algae according to the present invention, and an underwater flowerpot (9) is inserted into a net knot, thereby culturing hydrophilic aquatic plants (6). Multiple holes (11) are bored on the outer side surface of the underwater flowerpot (9) such that roots of aquatic plants (6) grow out of the holes, absorb nutrients dissolved in water, and grow. Multiple holes (11) are bored on the outer side surface of a water surface flowerpot (10) such that roots of aquatic plants (6) grow out of the holes, absorb nutrients dissolved in water, and grow. Aquatic plants (6), which are used for the aquatic plant hydroculture facility (1) for preventing proliferation of green algae according to the present invention, are cultured in the summer season, when green algae breed, thereby purifying the water quality. |
