在单养鲢( Hypophthalmichthys molitrix)的塑料养殖箱中植入黄菖蒲( Iris pseudacorus) , 按黄菖蒲:鲢(生物量, g/m3)约为1:3、 2:3、 1:1、 4:3设置4个实验组(对照组不加黄菖蒲), 研究鲢养殖水体植入黄菖蒲对水质及鲢生长的影响. 每周定时测定养殖水体中TN、 TP、 COD的变化及黄菖蒲、 鲢鱼的生长情况等. 结果显示, 实验组水体TN、 TP和COD浓度相比无黄菖蒲组显著降低, 实验组对TN、 TP、 COD的清除率分别为: 生物量比1:3组(黄菖蒲 5 株): 63. 95%、 59. 06%、 46. 55%; 生物量比 2: 3 组(黄菖蒲 10 株): 80. 25%、 68. 46%、43. 84%; 生物量比1:1 组(黄菖蒲15 株): 78. 05%、 69. 13%、 31. 49%; 生物量比4:3 组(黄菖蒲20 株):75. 54%、 63. 76%、 27. 06%. 各实验组中黄菖蒲和鲢生长情况良好, 实验生物量比2:3组鲢特定生长率最高达0. 33%/d, 黄菖蒲特定生长率也最高. 结果表明: 在鲢养殖水体中引入水生植物黄菖蒲可以一定程度上改善养殖水质, 并促进鲢的生长.
在單養鰱( Hypophthalmichthys molitrix)的塑料養殖箱中植入黃菖蒲( Iris pseudacorus) , 按黃菖蒲:鰱(生物量, g/m3)約為1:3、 2:3、 1:1、 4:3設置4箇實驗組(對照組不加黃菖蒲), 研究鰱養殖水體植入黃菖蒲對水質及鰱生長的影響. 每週定時測定養殖水體中TN、 TP、 COD的變化及黃菖蒲、 鰱魚的生長情況等. 結果顯示, 實驗組水體TN、 TP和COD濃度相比無黃菖蒲組顯著降低, 實驗組對TN、 TP、 COD的清除率分彆為: 生物量比1:3組(黃菖蒲 5 株): 63. 95%、 59. 06%、 46. 55%; 生物量比 2: 3 組(黃菖蒲 10 株): 80. 25%、 68. 46%、43. 84%; 生物量比1:1 組(黃菖蒲15 株): 78. 05%、 69. 13%、 31. 49%; 生物量比4:3 組(黃菖蒲20 株):75. 54%、 63. 76%、 27. 06%. 各實驗組中黃菖蒲和鰱生長情況良好, 實驗生物量比2:3組鰱特定生長率最高達0. 33%/d, 黃菖蒲特定生長率也最高. 結果錶明: 在鰱養殖水體中引入水生植物黃菖蒲可以一定程度上改善養殖水質, 併促進鰱的生長.

The paper studied the effect of Iris pseudacorus implantation on water quality and feed efficiency in Hypophthal-michthys molitrix ponds. I. pseudacorus and H. molitrix were divided into 4 experimental groups, and biomass ratios were 1:3, 2:3, 1:1, 4:3 respectively (the control group without Iris pseudacorus). During the experiment, the variations of nutrients , survival and growth of the aquaculture water were detected every 7 days. The results showed that the nutrition and COD of experimental groups decreased significantly compared with the control group, the uptake rates of I. pseudacorus (5 strains) on nutrients of TN, TP and COD were 63. 95%, 59. 06% and 46. 55% respectively. In the I. pseudacorus ( 10 strains) system, the rates of nutrients uptake in order were 80. 25%, 68. 46%, 43. 84% respectively, and 78. 05%, 69. 13%, 31. 49% respectively in I. pseudacorus (15 strains) group, and 75. 54%, 63. 76%, 27. 06% respectively in I. pseudacorus (20 strains) group. While biomass ratios were 2: 3, the special growth rate ( SGR) of H. molitrix was 0. 33%, and the SGR of I. pseudacorus was the highest. The results showed that polyculture the H. molitrix with the I. pseudacorus can improve the quality of aquaculture water, and promote the growth of H. molitrix.
