一、适当加大池塘面积和水深 使池塘受风面及日照面增大，风力使池水水面形成风浪，增强了上下水层的混合，加速空气中的氧溶入水中，并且能提高生物造氧作用，从而提高池塘溶氧量。成鱼池以１０～２０亩为宜，鱼种池以５～１０亩为宜。池水深则鱼池的总溶氧量高，水温、水质较 First, an appropriate increase in the pond area and depth of the pond by the wind and sunshine increases, the wind to the surface of the water storm, enhanced mixing of the upper and lower water to accelerate the oxygen dissolved in the air into the water, and can improve bio-oxygen Role, thereby increasing the pond dissolved oxygen. Into a fish pond to 10 to 20 acres is appropriate, fish ponds to 5 to 10 acres is appropriate. The pool of deep fish pond total dissolved oxygen is high, water temperature, water quality
