现在、我国的池塘养鱼大都采用精养方式、亩产达700～1000公斤、其水质控制是养殖的关键.一般采用鱼池换水和利用增氧机的方法来调节水质.在7～9月份.鱼的主要生长期内由于大量投饲.加上鱼大量地排出粪便,水质极易恶化.为防止鱼晚间浮头,一般要在晚间提早启动增氧机、甚至有时在傍晚开机.直到次日凌晨.但开机的人为因素多、有的人凭经验开机、具有很大盲目性、因此具有诸多弊端.如多耗电能.可以计算一下.一个10亩鱼池.有2台3kW增氧机、由于盲目开机.每台每晚多开5小时、仅在7～9月份三个月就多耗电2700kW·h,这是一笔不小的支出.就鱼池的生态角度来讲.晚间在鱼池溶氧不致于引起鱼浮头的情况下要尽量推迟开机的时间.为了克服这种情况,我们尝试利用测氧仪来自动监控精养鱼池增氧机适时开机、实验证
Nowadays, most of the pond fish in our country adopt the intensive cultivation method, with a yield of 700-1000 kg per mu, and its water quality control is the key point for breeding. Generally, the fish pond is used to change the water and the aerator is used to regulate the water quality. In the main growth period of the fish due to a large number of feeding together with a large number of excrement of fish excrement, very easily deteriorated water in order to prevent fish floating at night, usually in the evening to start early aerator, or even start in the evening until the next day But the power of human-induced boot, and some people start with experience, with great blindness, it has many drawbacks, such as more energy consumption can be calculated. A 10 acres of ponds. There are 2 3kW aerator, Due to blind boot. Each open more than five hours per night, only in the three months from September to September more power consumption 2700kW · h, this is not a small expenditure in terms of ecological aspects of the fish pond. Evening in the fish pond Dissolved oxygen will not cause fish floating head case to try to postpone boot time.In order to overcome this situation, we try to use the oxygen meter to automatically monitor the intensive fish tank aerator boot time, the actual proof
