is suitable for fat water ponds? Fat water ponds are suitable for silver carp, bighead carp and other fish. The reason why these two kinds of fish are suitable for raising is mainly related to their feeding habits. There are many common economic fish, most of which are omnivorous, herbivorous or carnivorous, but silver carp and bighead carp are filter-feeding. There are more plankton in the fertile water, so it is easier for silver carp and bighead carp to grow and develop, so that they can be fattened and economic benefits can be improved.
of fertilizer and water? 1. Do not apply fertilizer and water in rainy days: The cultivation of fertilizer and water is completed through fertilization, but not all weather is suitable for fertilization, generally in rainy days can not be fertilized. Because the weather in rainy days is dark and the light is very weak, the ability of phytoplankton to absorb nutrients is poor, and more organic matter enters the pond with rainwater, which can play a certain role in itself, and the fertilizer efficiency of fertilization will also be reduced.
2. If the water in the fish pond is muddy, it is not suitable for fertilization. Turbid water indicates that it has more clay or mineral particles, and fertilizer is easily stained with fixed precipitation, so it can not play the role of fertilizer water, wasting fertilizer in vain.
3. Single fertilizer is not applied: single fertilizer must not be applied. Single fertilizer is of limited help to the growth of plankton. Therefore, compound fertilizer should be chosen. The ratio of nitrogen, phosphorus and potassium is 2:2:1. This effect will be better. If single fertilizer is applied, it will also affect other fertilizer efficiency.
