合理使用增氧机,不但可以预防和减轻鱼浮头,还可加强池塘水体物质循环,改善水质。但在使用过程中,必须注意以下几点: 1.晴天中午开机。由于晴天池水上下层温差较大,加之上下水层对流缓慢,使下层水体中溶氧得不到及时补充。这时开机可加快水层的对流交换,缩小上下层水的温差和使下层水体溶氧得到补充。 2.阴天清晨开机。因为阴天日照强度弱,池水中浮游植
Proper use of aerator, not only can prevent and reduce the floating head of fish, but also enhance the pond water material circulation, improve water quality. However, in the process of using, we must note the following: 1. Sunny noon boot. Due to the large temperature difference between the upper and lower layers of the sunny day, and the slow convection of the upper and lower aquifers, the dissolved oxygen in the lower layer of water can not be replenished promptly. At this time, the boot can speed up the convective exchange of the water layer, reduce the temperature difference between the upper and lower water, and make the dissolved oxygen in the lower water body be supplemented. 2. Cloudy morning boot. Because of the cloudy daylight intensity is weak, the pond water phytoplankton
