为解决河南中牟县万滩镇养殖池塘机械增氧技术单一的问题,通过试验研究微孔式、水车式、涌浪式等几种增氧机的性能及使用方式,以达到提升增氧效果和提高养殖效益的目的。结果表明,该地区池塘溶氧含量高而利用率低,养殖户传统增氧方法不当。适宜增氧方式为：涌浪式增氧机适合在晴天下午使用3~6 h,可有效提升周边20 m范围内底层水体的溶氧水平；投食前后半小时开启和关闭微孔式、水车式增氧机,可提升投食期间投饵区溶氧水平1~2 mg/L,保证鱼群的进食效果；夜间搭配使用微孔式和低功率叶轮式增氧机增氧,可使微孔区域底层水体溶氧比不增氧状态高出1 mg/L以上。%To solve the problem of single mechanical aeration technology in aquaculture ponds of the Wantan town in Zhongmu, Henan province, we compared the performance and application scope of various aerators, including micropore, waterwheel and surge aerator, and achieved the purpose of enhancing the effect of oxygen and improving the breeding effi-ciency. Results showed that water in the tested ponds contained sufficient dissolved oxygen itself but with low utilization rate, and the farmers usually used improper methods of aerators. The surge type of aerator should be used 3~6 h in sunny afternoon, since it made full use of the dissolved oxygen produced by the surface phytoplankton. According to weather con-ditions, the microporous aerator and waterwheel aerator should be used along or together before and after half an hour of feeding, which effectively improved the oxygen level of feeding areas by 1 ~2 mg/L. The microporous aerator and low power impeller type of aerator used together in rainy day and night expanded the aeration area, improved the underlying dissolved oxygen 1 mg/L.
