chicken manure fertilizer water is used per mu to apply chicken manure fertilizer water to fish ponds, not only considering the area, but also considering the water depth, usually 60-100 kg per mu per meter of water depth, that is, about 2-3 kg per cubic meter. Chicken manure is a very good fertilizer, but it can not be directly put into the fish pond, it needs to be fermented with bacterial liquid first, which usually takes about 7-10 days. Fermented chicken manure can be put into the fish pond, and probiotics should be added to regulate the water quality.
of fertilization? 1. Algae cultivation: The primary benefit of fertilization in fish ponds is algae cultivation. Although algae outbreaks are harmful to water quality and fish, water without algae can not keep fish alive. As long as the balance of algae is guaranteed, there will be no problem with water quality. Algae has many functions, besides releasing oxygen through photosynthesis, it can also be used as food for fish.
2. Supplement nutrition: Fertilization has many benefits. It not only allows plankton to grow in large quantities, but also improves the nutrients in the water. The increase of various ions is also helpful to the growth of fish. If the water is too thin, the development of the fish will also be affected, not only the growth is not good, but also the price is not high.
3. Reduce ammonia nitrogen: As mentioned above, fertilization can promote the growth of algae and plankton, which can absorb harmful substances in the water to a certain extent. The most direct way is to reduce the content of ammonia nitrogen. Ammonia nitrogen is harmful to fish, so reducing ammonia nitrogen is also very helpful to the health of fish.
