调节水质的目的是为鱼类创造一个适宜的生活环境。过去,水质调节主要是结合池塘的日常管理,采用适当施肥、定期搅动塘泥、适时加注新水等常规方法。近年来,有些地方结合生产实际,采用了一些新的水质调节方法,现介绍如下: 一、机械调节法主要是采用增氧机调节水质。目前使用的增氧机有叶轮式、喷水式、水车式、充气式等类型,它们的结构和工作原理虽不同,但都具有造成池水对流、增加溶氧、散发水中的有毒气体等调节水质的作用。机械调节的优点在于既能提高池水的溶氧量,改进池水的化学性状,又不至于降低 The purpose of regulating water quality is to create a suitable living environment for fish. In the past, the water quality adjustment was mainly based on the daily management of the pond. Regular fertilization, periodic agitation of pond mud, timely filling of fresh water and other conventional methods were used. In recent years, some places combined with the actual production, the use of a number of new water quality control methods are presented below: First, the mechanical adjustment method is mainly used aerator to regulate water quality. Currently used aerator impeller type, water jet, waterwheel, inflatable and other types of their structure and working principle are different, but have caused the pool water convection, increase dissolved oxygen, the distribution of toxic gases in water and other adjustments The role of water quality. The advantage of mechanical adjustment is that it not only can improve the dissolved oxygen in the pool water and improve the chemical properties of the pool water,
