豫北(bei)鈣業(ye)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)的(de)用(yong)(yong)(yong)(yong)法(fa)(fa)用(yong)(yong)(yong)(yong)量(liang)(liang)： 干(gan)法(fa)(fa)清(qing)池：畝(mu)用(yong)(yong)(yong)(yong)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)70一(yi)(yi)80kg (如淤泥多可(ke)將(jiang)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)增(zeng)量(liang)(liang)10％左右)。 方法(fa)(fa)：清(qing)塘(tang)(tang)時在(zai)塘(tang)(tang)底挖幾(ji)個小坑,或(huo)用(yong)(yong)(yong)(yong)木(mu)桶等(deng),把生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)放(fang)人加(jia)水(shui)溶化,不待冷卻立即均(jun)勻向四周(zhou)全(quan)池潑(po)灑(sa)(sa)(包括堤岸(an)腳、池壁),第二(er)(er)天早晨好(hao)用(yong)(yong)(yong)(yong)耙(pa)(pa)耙(pa)(pa)動塘(tang)(tang)泥,消毒效(xiao)果(guo)(guo)更好(hao). 帶水(shui)清(qing)池：每(mei)畝(mu)平均(jun)水(shui)深1米(mi)(mi)用(yong)(yong)(yong)(yong)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)125一(yi)(yi)150kg。方法(fa)(fa)：將(jiang)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)放(fang)人木(mu)桶或(huo)水(shui)缸中溶化后(hou)立即全(quan)池遍灑(sa)(sa),潑(po)灑(sa)(sa)時要(yao)到(dao)邊到(dao)位，尤其池塘(tang)(tang)四周(zhou)不要(yao)忽視，7-8天藥力消失后(hou)方可(ke)放(fang)魚。 殺菌(jun)消毒：每(mei)畝(mu)平均(jun)水(shui)深1米(mi)(mi)用(yong)(yong)(yong)(yong)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)15-20kg。 方法(fa)(fa)：全(quan)池潑(po)灑(sa)(sa)，用(yong)(yong)(yong)(yong)藥后(hou)要(yao)察看魚的(de)反(fan)響(xiang)，以防劑量(liang)(liang)太大、PH陡變魚產生(sheng)過大的(de)應激而死亡(wang)。 二(er)(er)、注(zhu)意(yi)事(shi)項(xiang)： 1.生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)長時間在(zai)空氣中暴露會吸收二(er)(er)氧化碳(tan)(tan)變成(cheng)粉(fen)末狀(zhuang)(zhuang)碳(tan)(tan)酸鈣，起不到(dao)清(qing)塘(tang)(tang)消毒的(de)作(zuo)用(yong)(yong)(yong)(yong)。因而生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)好(hao)現買現用(yong)(yong)(yong)(yong)，且選擇塊狀(zhuang)(zhuang)較(jiao)輕、不含(han)雜質的(de)為(wei)好(hao)。若(ruo)一(yi)(yi)次用(yong)(yong)(yong)(yong)不完剩(sheng)下(xia)的(de)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)用(yong)(yong)(yong)(yong)塑料(liao)袋扎口密封保管。 2.生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)加(jia)水(shui)成(cheng)氫(qing)氧化鈣漿后(hou)要(yao)趁熱(re)潑(po)灑(sa)(sa)，不可(ke)將(jiang)整塊石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)扔(reng)到(dao)池中消毒，這樣(yang)效(xiao)果(guo)(guo)不理想。 3.鹽堿池塘(tang)(tang)或(huo)池塘(tang)(tang)水(shui)體pH值(zhi)大于8時不能用(yong)(yong)(yong)(yong)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)。 4.做為(wei)藥用(yong)(yong)(yong)(yong)或(huo)調水(shui)用(yong)(yong)(yong)(yong)時，全(quan)池潑(po)灑(sa)(sa)要(yao)避開(kai)中午高溫時間和(he)傍晚用(yong)(yong)(yong)(yong)藥，全(quan)池潑(po)灑(sa)(sa)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)要(yao)謹慎，若(ruo)遇天氣突變，很容易形成(cheng)池水(shui)水(shui)質劇(ju)變而死魚。同樣(yang)，悶熱(re)、雷陣雨天氣不宜(yi)全(quan)池潑(po)灑(sa)(sa)生(sheng)石(shi)(shi)(shi)(shi)(shi)灰(hui)(hui)，否則會形成(cheng)次日清(qing)晨缺(que)氧泛池的(de)發作(zuo)。
