【摘要】 为了能更深入的研究和应用池塘养殖河蟹底层微孔曝气技术,通过定时、定距、分层采集试验河蟹池塘水质并测定其溶解氧来确定单个PVC盘状管能改善水中溶解氧的最大范围和效果,结果表明:PVC盘状作用范围为1-10米,而作用深度为水下一米。河蟹池塘底PVC盘间适宜间距为15-20米,增氧开机时间最好为凌晨4-6点,持续开机两个小时。更多还原

【Abstract】 In order to better study and application of microporous aeration pond crab underlying technology,timing,distance,hierarchical collection experimental crab Ponds and determination of dissolved oxygen to determine a single PVC pipe coils can improve the maximum range of dissolved oxygen and effects,the results showed that: PVC discoid scope of 1-10 meters,while the role of the next m depth of water.Crab pond bottom PVC plate suitable spacing between 15-20 meters,aerobics boot time is preferably at 4-6 am,continuous power for two hours.更多还原
