In pond culture, the main purpose of fertilizing water is to promote the growth of plankton and provide sufficient natural feed for farmed fish. At the same time, fertilizer water can also regulate water quality, improve the self-purification ability of water bodies, and reduce the occurrence of diseases. Especially in winter, when the water temperature in the pond is low, the growth rate of plankton slows down, so fertilizer water is even more important. So, what is the best fertilizer for pond fertilizer water?
Amino acid fertilizer:Amino acid fertilizer is a kind of nutrients rich in a variety of amino acids, trace elements and other nutrients, we commonly use: multi-effect fertilizer water pioneer, with small molecules and easy absorption, low temperature and rapid fertilizer water, etc., is recognized by more and more aquaculture farmers.
Organic fertilizer:Organic fertilizer is a fertilizer rich in organic matter that provides the nutrients needed in the pond and promotes the growth of algae and plankton. Commonly used organic fertilizers include livestock and poultry manure, crop straw, cake meal, etc. When applying organic fertilizer, it is necessary to pay attention to sufficient decomposition to avoid polluting water quality and spreading diseases.
Fertilizer:Chemical fertilizer is a kind of synthetic fertilizer, containing a large amount of nitrogen, phosphorus, potassium and other nutrients, with the advantages of easy use, quick effect, low cost, etc., but long-term use will cause adverse effects on water quality and destroy the ecological balance of water bodies. Commonly used fertilizers include urea, superphosphate, potassium sulfate, etc. Fertilizer:
Bio-fertilizer:Biological fertilizer is a new type of fertilizer and water method, commonly used biological fertilizer: EM bacteria pioneer, ultra-high concentration EM strains, mainly using microbial agents and other bioactive substances to promote the growth and reproduction of plankton. Biofertilizer has the advantages of safety, environmental protection and high efficiency, which can significantly improve water quality and yield. At the same time, biofertilizer can also improve soil structure and improve the water and fertilizer retention capacity of soil.
It is important to note that it is also very important to choose the appropriate time for fertilization. In general, spring and autumn are the best times for fertile water, as the water temperature is suitable and algae and plankton grow faster. In summer, the temperature is high, and the growth rate of algae and plankton is slow, so it is not suitable for fertilizing water.
Secondly, in winter, due to the lower temperatures, the growth rate of aquatic plants and algae is slower, therefore, it is necessary to choose fertilizers suitable for low temperature environments. For example, the pioneer of multi-effect fertilizer and water, rich in a variety of amino acids, trace elements and other nutrients, small molecules and easy to absorb, can be low temperature and rapid fertilizer water. Finally, remind everyone that the following points need to be paid attention to in winter fertilizer and water:
1. It is necessary to pay attention to controlling the amount of fertilizer to avoid excessive fertilization leading to eutrophication of water bodies.
2. It is best to choose the morning or evening of a sunny day for fertilizer and water in winter, and avoid fertilizing during high temperature periods.
3. It is necessary to maintain the fluidity of the water body, so that the fertilizer can be evenly distributed throughout the water body.
In short, choosing the right fertilizer, the right time and method of fertilization can improve water clarity, improve water quality, and enhance the resilience of fish. However, it is necessary to avoid excessive fertilization that leads to eutrophication of water bodies and affects fish growth.
