适时开启增氧机,可以改善水质,促进池塘物质循环,预防和减轻鱼浮头发生,如开机不当,则会起到相反的效果。 1、晴天中午开机。晴天池水上下温差较大,水受热阻力大,上下层水对流甚微,下层氧得不到及时补充,如果在晴天中午开机,就可以冲破水的阻力。使上下层水得以交换,温差和氧差也大大减少,下层水氧气也得以补充。
Timely open the aerator, can improve water quality, promote pond material circulation, prevent and reduce the occurrence of fish floating head, such as improper boot, it will play the opposite effect. 1, sunny at noon boot. Sunny sky water temperature difference between the upper and lower water resistance by heat, the upper and lower water convection is very small, the underlying oxygen can not be replenished, if the boot in the sunny noon, you can break through the water resistance. So that the upper and lower water can be exchanged, the temperature difference and oxygen difference is also greatly reduced, the lower water oxygen can be added.
