Sodium bicarbonate, also known as acid sodium carbonate, sodium bicarbonate, baking soda, heavy alkali, baking alkali, is a acid salt generated after the neutralization of strong alkali and weak acid. When dissolved in water, it presents a weak alkaline, and can quickly neutralize stomach acid after internal administration, and its anti-acid effect is weak and short. In addition, there is the role of alkalizing liquid. It is suitable for excessive stomach acid, dyspepsia and alkalized urine. Intravenous administration for acidosis; External ear drops to soften cerumen; 2% solution sitz bath for fungal vaginitis. In veterinary clinic, it is mainly used to treat gastrointestinal catarrhal inflammation, sepsis and severe diarrhea, large area burn, and neutralize gastric acid and alkalized urine. Spraying sodium bicarbonate in greenhouse can not only prevent disease, but also increase production. Many diseases such as cucumber powdery mildew, anthracnose, tomato leaf mildew and so on, the pathogen of euchemicalbook is difficult to survive under alkaline conditions. The effect of dissolving with 500 times baking soda is very good. In addition, carbon dioxide is the raw material of photosynthesis, because of the closed compartment, carbon dioxide is often insufficient, spray baking soda decomposition can supplement carbon dioxide. Can be sprayed every 3-4 days during the growth of vegetables; Adding proper amount of sodium bicarbonate to livestock feed can effectively improve the digestibility of livestock and poultry feed, increase the laying rate and eggshell strength of laying hens, accelerate the utilization of nutrients and excretion of harmful substances, and increase the weight gain rate of livestock and poultry. It can always keep the resistance and immunity of livestock and poultry body in the best state, improve the anti-stress ability of livestock and poultry, and play a positive role in preventing diseases of livestock and poultry and ensuring their healthy growth.
