The use of fertilized water in aquaculture is an important management technology, which can effectively improve the productivity and water quality of aquaculture water bodies, and promote the growth and health of aquaculture objects.
1. Microbial fertilizer. Microbial fertilizer contains a large number of beneficial microorganisms, which can promote the decomposition and degradation of harmful substances in water, improve the water quality environment, and facilitate the growth and reproduction of plankton and benthic organisms in the water body. In addition, we can use: multi-effect fertilizer and water pioneer: rich in a variety of amino acids and trace elements and other nutrients, small molecules are easy to absorb, and can quickly fertilizer water at low temperature.
2. Organic fertilizer. Organic fertilizer is a fertilizer made of organic matter such as animal and plant residues, feces, etc., which is rich in organic matter and nutrients, and has a significant role in promoting the growth and reproduction of plankton and benthic organisms in the water body.
3. Chemical fertilizers. Chemical fertilizers can provide certain inorganic nutrients, such as nitrogen, phosphorus, potassium, etc., to promote the growth of plants in the water, thereby providing more food for plankton in the water body.
Proper fertilization can improve the water quality of fish ponds and increase the yield and quality of fish. Here are some tips on water fertilizer for fish ponds.
1. When fertilizing, it is necessary to pay attention to the method and amount of fertilization. In general, fertilization should be carried out in a dispersed manner to avoid over-fertilization at one time, which can cause eutrophication of water bodies and fish death.
2. Choose the right type of fertilizer and how to use it, which can improve the water quality of fish ponds and increase the yield and quality of fish. When carrying out fish pond culture, we must pay attention to the method and amount of fertilization to ensure the health and stability of the fish pond water body.
