| Experiments have been carried out in barge enclosure near Bukhangang area and arificially eutrophicated pond. Applied plants are three terrestrial plants (Big cone pine, Pine needles and Ginkgo) and one aquatic plant (Water chestnut). In the experiment pond, applied plants are big cone pine, pine needles and ginkgo at the concentration of 0.5 g/l and water chestnut of 0.3 g/l. And it used pine needles at the concentration of 0.3 g/l in barge enclosure. The dominant species was Microcystis aeruginosa. Chlorophyll a concentration decreased to the extent of average 65% as compared with the beginning of experiment by the input of big cone pine and pine needles in artificially eutrophicated pond. But it was decreased to the extent of average 34% by the input of water chestnut. Especially, pine needles significantly inhibited the growth of algae from the early days in barge enclosure, it was declined at a rate of average 74%. It was proved that pine needles was the most inhibitory to the growth of algae at the treatment with $0.3{sim}0.5;g/l$, Ginkgo and water chestnut are needed more study. We purified that the dissolved phenolic compounds from the various plants can affect algal growth. |
