After the super typhoon, it is necessary to use Guangxi rotary kiln lime particles to clear the pond, mainly because it can effectively kill bacteria and pests, regulate the physical and chemical properties of the substrate, and improve the basic fertility of the water body. The specific reasons are as follows:

Strong alkaline sterilization and pest control: Lime particles react with water to produce calcium hydroxide, causing a sharp increase in the pH value of the water to above 12. This strong alkaline environment can destroy the cell structure of pathogens, parasites, pests, and weed seeds, leading to protein denaturation and loss of physiological functions, thereby completely killing harmful organisms and reducing the risk of subsequent breeding diseases.

Adjusting the physical and chemical properties of the sediment: Calcium hydroxide will penetrate into the sediment at the bottom of the pond, neutralize the acidic substances in the sediment, reduce the acidity of the sediment, and improve the problem of "acidification" of the sediment. At the same time, it can combine with phosphate, iron, and manganese ions in the sludge to form stable sediment, reduce the release of harmful ions in the water, loosen the sludge structure, increase the permeability of the sediment, and promote beneficial microbial activity.

Improving the basic fertility of water bodies: The calcium salts produced by lime reaction are essential nutrients for water bodies and aquatic organisms, providing a calcium source for phytoplankton and promoting their reproduction. Phytoplankton are not only natural feed for aquaculture organisms, but also increase dissolved oxygen in water through photosynthesis, laying a good ecological foundation for subsequent aquaculture.
