水是鱼类生活的环境,同时又是其饵料生物的栖息繁育生长的场所,因此水质的好坏直接影响鱼类养殖产量及其经济效益。新县属典型的山区,俗称“八山一水一分田”,并且这“一分水和田”均呈酸性,对农作物种植和池塘养鱼的影响很大。所以根据不同水质状况,采取相应的技术措施改良水质是十分必要的。1 影响新县池塘水质的主要因素新县土壤PH平均值为5.83,绝大多数偏酸性(变幅为4.8～6.9),渗水性大。池塘水质PH值在6～6.5,呈酸性。PH值影响水中胶体系统对某些离子的吸附和释放,从而影响施肥的效果,同时影响水中氨和铵离子的平衡,以致影响鱼类及其饵料生物的
Water is the living environment of fish, and at the same time, it is the habitat breeding and growth place of its food organisms. Therefore, the quality of water has a direct impact on the fish culture output and its economic benefits. New County is a typical mountainous area, commonly known as “a mountain of water and a field”, and “a water and field” are acidic, crop cultivation and fish ponds have a great impact. Therefore, according to different water quality, to take appropriate technical measures to improve water quality is very necessary. 1 The main factors affecting the water quality of new county ponds The average soil PH in New County was 5.83, the vast majority of acidic (amplitude of 4.8 to 6.9), permeability. Pond water PH value of 6 to 6.5, was acidic. PH value affects the adsorption and release of certain ions by the colloidal system in the water, thus affecting the effect of fertilization and the balance of ammonia and ammonium ions in the water, so as to affect the biology of the fish and its bait
