生石灰的主要成份是氧化钙,其资源丰富,价格低廉,在淡水养殖上得到广泛应用。生石灰既可以净水、调泥,又可以杀菌、治病、肥水等,已成为养殖者创高产的重要法宝。 1、生石灰作为水源、池水PH值的调节剂。 养鱼用水要求PH值在6.5—8.5的范围中,但在养殖期间,由于施肥、投饵和生物代谢的积累,使池水向酸性转化。在偏酸性水中藻类生长受到抑制、肥水很难,并会产生一系列的酸反应,形成有害产物,致使鱼生长慢、易患病,病原微生物繁殖快。根治这一危害的有效方法就是每半月向池中泼洒生石灰乳一次,使池水PH值保持在7以上的偏碱状态。 2、生石灰作为底质消毒、改良剂。
The main component of quicklime is calcium oxide, which is rich in resources and low in price. It is widely used in freshwater aquaculture. Lime can not only clean water, adjusting mud, but also sterilization, healing, fertilizer, etc., has become a farmer to create an important magic weapon. 1, Lime as a water source, pool water PH regulator. Fish farming requires PH values in the 6.5-8.5 range, but during aquaculture, the water is converted to acid due to the accumulation of fertilizers, feeding and bio-metabolism. In acidic water, algae growth is inhibited, fertilizer and water is difficult, and will produce a series of acid reaction, the formation of harmful products, resulting in slow growth of fish, susceptible to disease, rapid propagation of pathogenic microorganisms. An effective way to cure this damage is to spray the lime milk once every half month to keep the PH value of the water at a level above 7. 2, Lime as a substrate disinfection, improver.
