摘要
研究了金鱼藻对铜绿微囊藻生长的抑制效应。结果表明:高浓度的金鱼藻种植水抽滤液和植株研磨水提液对铜绿微囊藻的生长有极明显的抑制作用;低浓度则几乎没有抑制作用。同一浓度下,金鱼藻植株研磨液的抑制效应比种植水更为明显,抑制效应持续时间也更长。20℃培养下的金鱼藻,其植株研磨液的抑制效应最明显。高浓度的嫩枝嫩叶部位的金鱼藻植株研磨液对铜绿微囊藻的生长有更明显的抑制作用,低浓度的老茎老叶部位的金鱼藻植株研磨液对其生长则表现出一定的促进作用。
Inhibitory effects of Ceratophyllum oryzetorum Kom. on the growth of Microcystis aeruginosa Kütz. has been investigated. The results showed that the liquor cultured with C. oryzetorum and the extract of C. oryzetorum have differential inhibitory effects on M. aeruginosa. The high concentration of the liquor cultured with C. oryzetorum and the extract of C. oryzetorum can inhibit the growth of M. aeruginosa. The low concentration of them have no inhibitory effects on the growth of M. aeruginosa. And the tender plants have the best inhibitory effects on the of M. aeruginosa, the old plants can accelerate their growth. The extract of C. oryztorum can inhibit the growth of M. aeruginosa obviously at 20℃.
