【摘要】 通过在洛阳市静水养鱼池塘高产试验区内选取有代表性的池塘,进行水质调控技术的研究,初步探索出本地区高产鱼塘的水质调控技术和水质标准。当溶解氧6.3±0.49mg/l、有机物耗氧22.05±1.86mg/l,总氮2.029±0.2262mg/l、磷酸盐0.1797±0.0306mg/l、总硬度11.8±0.5639德国度、PH值8.02±0.5639时,可以达到亩净产鲜鱼400kg以上。更多还原

【Abstract】 we had a study on the techniques of water-quality control and have made a priliminary exploration of the control techniques and the standard of water quality In high-yield fishpond of this area through selecting the representative ponds in the high -yield experimental area of still-water fishpond in Luo Yang city. The net output of fresh fish can be reached to 400kg per mu when dissolved oxygen is 6.3±0.49mg/l; oxygen consumed by organic matter is 22.05±1.86mg/l; the total nitrogen is 2.029±0.2262mg/l;phosphate is 0.1797±0.0306mg /1; the total hardness is 11.8±0.5639 Germany’s standard of hardness and pH value is 8.02±0.0596,更多还原
