朔州豫北鈣業(ye)工業(ye)級(ji)氫氧(yang)化(hua)鈣它能夠起(qi)到殺菌，施肥(fei)，改水(shui)(shui)，與調節(jie)池(chi)塘酸堿度的(de)作用(yong)(yong)。還可以(yi)起(qi)到消(xiao)(xiao)毒(du)，改善低(di)質(zhi)與調節(jie)水(shui)(shui)質(zhi)的(de)作用(yong)(yong)。以(yi)下是生(sheng)(sheng)石(shi)(shi)灰(hui)(hui)石(shi)(shi)灰(hui)(hui)清塘的(de)作用(yong)(yong)及使(shi)用(yong)(yong)方法。生(sheng)(sheng)石(shi)(shi)灰(hui)(hui)清塘的(de)使(shi)用(yong)(yong)方法熟石(shi)(shi)灰(hui)(hui)魚(yu)塘消(xiao)(xiao)毒(du)。石(shi)(shi)灰(hui)(hui)排(pai)水(shui)(shui)清塘，通常(chang)情況下每畝(mu)(mu)使(shi)用(yong)(yong)生(sheng)(sheng)石(shi)(shi)灰(hui)(hui)50—80kg，如果使(shi)用(yong)(yong)的(de)生(sheng)(sheng)石(shi)(shi)灰(hui)(hui)質(zhi)量(liang)(liang)(liang)比較差或者池(chi)底淤泥較多時(shi)(shi)．用(yong)(yong)量(liang)(liang)(liang)可增(zeng)加(jia)至90—150kg。施用(yong)(yong)時(shi)(shi)在池(chi)底挖幾(ji)個淺(qian)坑(keng)。坑(keng)的(de)數量(liang)(liang)(liang)和距離好能將石(shi)(shi)灰(hui)(hui)漿潑(po)灑(sa)(sa)至全池(chi)為度。把石(shi)(shi)灰(hui)(hui)施放(fang)于坑(keng)內，等吸水(shui)(shui)散開(kai)(kai)后攪勻，趁熱潑(po)灑(sa)(sa)全池(chi)。石(shi)(shi)灰(hui)(hui)帶水(shui)(shui)清塘，當池(chi)塘水(shui)(shui)深lm時(shi)(shi)，每畝(mu)(mu)使(shi)用(yong)(yong)石(shi)(shi)灰(hui)(hui)250—300kg，將生(sheng)(sheng)石(shi)(shi)灰(hui)(hui)放(fang)于鐵桶(tong)內加(jia)水(shui)(shui)化(hua)開(kai)(kai)后全池(chi)潑(po)灑(sa)(sa)。我們都知道生(sheng)(sheng)石(shi)(shi)灰(hui)(hui)的(de)主要成分是氧(yang)化(hua)鈣．遇水(shui)(shui)后會生(sheng)(sheng)成氫氧(yang)化(hua)鈣并放(fang)出熱量(liang)(liang)(liang)。熟石(shi)(shi)灰(hui)(hui)是一(yi)種強堿．可短(duan)時(shi)(shi)間使(shi)池(chi)水(shui)(shui)的(de)pH達到中性。
