对生活在池塘水体中的鱼类来说,池水既是生存的载体,又是食物、氧气的来源,还是排泄废物的场所。因此,人们称我们的池塘养鱼具有“三塘合一”的功能,即集育饵塘、养鱼塘、氧化塘于一体。但是,肥料特别是有机肥的施用,不仅消耗池中氧气,而且改变了池塘水质的酸碱度等理化性状,带来了池水容易恶化的严重水质问题,以至于稍不留意就出现浮头、泛塘等死鱼事故,造成养鱼损失。 For fish living in pond water, water is both a viable carrier, a source of food, oxygen, and a place to discharge waste. Therefore, people call our pond fish a “three ponds one” function, which integrates bait ponds, fish ponds and oxidation ponds in one. However, the application of fertilizers, especially organic fertilizers, not only consumes oxygen in the pool, but also changes physical and chemical properties such as the pH of the pond water, resulting in serious water quality problems that easily deteriorate in the pond water, so that floating heads and pan ponds are noticed Dead fish accident, resulting in loss of fish.
