摘要
本文通过添加自制新型底质改良剂于养殖青虾的土池进行了65天的试验,测定了虾池的水质指标和青虾养殖的效果。试验结果表明,1) 添加底质改良型后,青虾养殖池塘中硝氮平均去除效率为73.35%,亚硝氮平均去除效率为67.84%,氨氮平均去除效率为71.99%;2) 添加了底质改良型的处理组养成的青虾规格、单位产量和成活率均显著高于对照组,饲料系数与对照组差异不显著。
To examine the effects of the growth of Macrobrachium nipponense and water quality regulation, a 65-day experiment was conducted self-made new-pattern sediment ameliorants in this paper. The results showed that, 1) compared control ponds, the average clearance rate of nitrate nitrogen was 73.35%, the average clearance rate of nitrite nitrogen was 67.84%, the average clearance rate of ammonium nitrogen was 71.99% in sediment ameliorant group of Macrobrachium nipponense culture ponds;2) after Adding new-pattern sediment ameliorants, the Body weight, unit production and survival rate of Macrobrachium nipponense was siganificantly higher that that of control group (P 0.05).
