由于地理条件的限制,我国有许多地方养鱼的水源全靠地下井水。但井水温度低,溶氧量少,水质清瘦,直接用来养鱼,不利于鱼类的生长。为了使注入鱼池的地下井水达到利于鱼类生长的肥、活、嫩、爽,就必须人为地进行培肥。根据我国立体养殖鱼类的特点,介绍一下培肥井水的具体方法,以供参考。 Due to the limitation of geographical conditions, there are many places in our country that rely on underground well water for fish farming. However, well water temperature is low, dissolved oxygen less, thin water, directly used to fish, is not conducive to the growth of fish. In order to make the underground well water injected into fish ponds achieve the benefit of the growth of fish, live, tender and cool, they must artificially fertilize. According to the characteristics of China’s three-dimensional breeding of fish, introduce specific ways to cultivate well water for reference.
