浮游植物是养殖鱼类的天然饵料,也是池塘溶解氧的重要来源之一。其数量的多少和种类组成直接关系到鱼池的产量,合理施用各种肥料,使池塘水体保持良好的浮游植物组成,是发展水产养殖业,增加效益的重要途径之一。一、池塘施肥与浮游植物的关系池塘中施用不同的肥料,增加了水体中的各种营养元素,促使浮游植物繁殖和生长。不同的肥料和施肥方法,可以改变池塘浮游植物的数量及种群组成。鱼池施肥方式对浮游植物的组成影响大体有以下几种: Phytoplankton is a natural feed for farmed fish and is an important source of dissolved oxygen in ponds. The number of species and composition of species directly related to the production of fish ponds, the rational use of various fertilizers, pond water body to maintain a good phytoplankton composition, is to develop aquaculture, one of the important ways to increase efficiency. First, the relationship between pond fertilization and phytoplankton Pond in the application of different fertilizers, an increase of water in a variety of nutrients, to promote phytoplankton breeding and growth. Different fertilizers and fertilizers can change the number of pond phytoplankton and its population composition. Fish pond fertilization on the composition of phytoplankton generally have the following:
