1. Artificial fertilizer water.
We can add some fertilizer to the shrimp field to promote the growth of algae and fertilize the water. The commonly used artificial fertilizer water method is to use organic fertilizer or chemical fertilizer, and it is necessary to pay attention to controlling the amount when using it to avoid excessive use of crayfish. At the same time, it is also necessary to pay attention to changes in water quality and adjust the amount of fertilizer in time. We use: multi-effect fertilizer and water pioneer, rich in a variety of amino acids and trace elements, small molecules and easy to absorb, can quickly fertilizer water.
2. Biological fertilizer water.
The use of biological agents to promote the growth of algae can achieve the effect of fertilizing water. A commonly used bio-fertiliser method is to use microbial agents to break down organic matter in the water to produce nutrients and promote the growth of algae. We use: EM bacteria pioneer, high content, strong activity, rapid increase of beneficial microorganisms, promote the absorption and utilization of nutrients, and improve the water quality environment of shrimp fields.
3. Natural fertilizer and water.
Some aquatic plants can be planted in the shrimp fields, which can produce oxygen through photosynthesis while absorbing nutrients from the water, promoting the growth of algae in the water, which in turn promotes the fertilizer of water.
4. Precautions.
When fertilizing and watering, it is necessary to pay attention to controlling the amount of fertilizer to avoid excessive use of crayfish. At the same time, it is also necessary to pay attention to changes in water quality and adjust the amount of fertilizer in time. When choosing fertilizer, it is necessary to choose a fertilizer of reliable quality to avoid the use of inferior fertilizer that affects the growth of crayfish. In the process of breeding, it is necessary to conduct regular water quality testing to find water quality problems and deal with them in time.
