1. Oxidation and biological double effect bottom reform.
The substrate of aquaculture ponds is usually more complicated, and it is difficult to achieve a good bottoming effect with only one bottom modification product, so experienced breeding friends recommend using: double reform pioneer, containing a variety of bottoming ingredients, can be oxidized at the same time, biological bottoming, cleaning up harmful substances, reducing the accumulation of organic matter, 7-10 days to use once, to prevent substrate deterioration.
2. Microbial preparations.
Microbial agents are mainly used to improve the substrate, improve the water quality, improve the ecology of the aquaculture water, and promote the growth of aquaculture organisms. Common microbial preparations include photosynthetic bacteria, bacillus, lactic acid bacteria, etc. These microorganisms can decompose the organic matter in the sediment, reduce the harmful substances in the sediment, and also produce some nutrients to provide nutrients for the farmed organisms. We use: EM bacteria pioneer, high content and strong activity, purify hydroponic algae, degrade ammonia nitrogen, and improve the pond environment.
3. Chemical agents.
Chemical agents are also commonly used to modify the bottom of the product, such as copper sulfate, ferrous sulfate, etc. These chemicals kill pests in the sediment and also regulate water quality. However, it should be noted that the use of chemical agents needs to pay attention to the dosage and use method to avoid harm to farmed organisms.
4. Precautions.
Aquaculture bottoming is a very important part of the aquaculture process, which involves the quality of the aquaculture water body and the growth environment of the aquaculture organisms. Before using the modified bottom product, it is necessary to test the sediment and understand the specific situation of the sediment, so as to select the appropriate modified bottom product. It is necessary to pay attention to the dosage and use method of the bottom product to avoid harm to the farmed organisms. Observe the water quality and the growth of the cultured organisms in time, so as to adjust the use plan in time.
