石灰不仅是清塘消毒和防治鱼病的良药,而且是池塘水质、底质重要的改良剂,其主要作用有以下几个方面:一、施用石灰,可以中和池底淤泥中的各种有机酸,改变酸性环境,使池水呈微碱性反应,而微碱性的水体环境则有利于养殖鱼类及其饵料生物的生长;同时,水体中钙离子、碳酸根离子增多,水的碱度随之增大,缓冲能力增强,对稳定水质有积极的作用,所以,在总碱度、总硬度及 pH Lime is not only a good medicine for disinfecting and preventing fish diseases in Qingtang, but also an important improver for pond water quality and sediment quality. Its main functions are as follows: First, lime is used to neutralize all kinds of organic Acid, changing the acidic environment, so that the water pool was slightly alkaline reaction, while the slightly alkaline water environment is conducive to the growth of farmed fish and bait organisms; the same time, water, calcium ions, carbonate ions increased water basicity With the increase, the buffering capacity is enhanced, which has a positive effect on the stability of water quality. Therefore, the total alkalinity, total hardness and pH
