良好的水质是水生动植物生长的基础,必须在物理、化学和生物等方面都适合水生动植物生长发育的需求。随着水产品养殖技术的不断改进,为追求最大的经济效益,养殖密度越来越大,因此水质的调控和改良则成为精养塘稳产、高产的关键因素。 Good water quality is the basis for the growth of aquatic animals and plants, and must be suitable for the growth and development of aquatic animals and plants in terms of physics, chemistry and biology. With the continuous improvement of aquaculture technology, in order to pursue the greatest economic benefits, aquaculture density is more and more big, so the regulation and improvement of water quality become the key factor for steady and high yield of intensive ponds.
