1. Lime is an essential medicine for aquaculture. Its main component is calcium oxide, which is made by calcining limestone, dolomite, chalk, shells and other substances with high calcium carbonate content at 900 ~ 1 100℃. Lime is pungent, warm and toxic. Entering the liver and spleen meridians. It has the functions of eliminating dampness, killing insects, stopping bleeding, relieving pain and eating meat. It can be used for treating scabies, wet sores, traumatic hemorrhage, scald caused by soup and fire, hemorrhoid, proctoptosis and wart. Oral administration can stop diarrhea and leukorrhagia.
2. Lime can stimulate mucous membrane, saponify adipose tissue, dissolve protein, stimulate and corrode tissue. Therefore, attention should be paid when using it: it is disabled when ammonia nitrogen is high; It is forbidden to use quicklime and hydrated lime when lacking oxygen; Use with caution when gill diseases occur; Can not be used with metal drugs; Can not be used with live bacteria; Disabled after using trichlorfon; Use with caution when the hardness is too high; Use with caution when the pH value is too high; Quicklime cannot be used with strong oxidant; Use with caution when liver is necrotic.
3. The water quality such as turbidity, submergence, dead algae, oil film and foam is treated by using the adsorption and complexation characteristics of sodium humate. Such as water purifying agent (such as polyaluminum and activated carbon) and oxidant (such as chlorine dioxide, potassium persulfate and potassium ferrate). ), bacterial preparations (such as photosynthetic bacteria, spores, lactic acid bacteria, etc.). ) and antidotes (such as organic acids, EDTA, baking soda, etc. ), the water purification effect will be better.
4. Pay attention to the adsorption of sodium humate, and naturally there will be a common problem of adsorbing drugs: toxic effect. Especially for benthic organisms such as shrimps and crabs, this side effect must be paid special attention to. It is precisely because this side effect has a subsequent impact on the water body that farmers did not notice it when using it, which will lead to many undesirable effects. For example, poisoning will naturally consume a lot of oxygen. The role of oxygen-consuming natural algae and fungi will be reduced.
5. Humic acid is an excellent carbon source fertilizer after decomposition. Some special usage can also stimulate the rapid propagation of algae, and this usage should be more cautious when the breeding environment deteriorates.
