一、生石灰是理想的清塘药物。养鱼池每隔1～2年需要清塘1次,以杀灭潜伏在鱼池和淤泥中的敌、病、虫害。生石灰不仅能杀死残留在鱼池中的野鱼、蛙卵、蝌蚪、水生昆虫、螺类、青泥苔等,还可杀灭微生物、寄生虫病原体及其休眠孢子。用生石灰清塘,如果是干塘,每亩施50～75公斤;水塘,1亩1米深的水面施125～150公斤。 First, the quick lime is the ideal of clear pond medicine. Fish ponds need to be cleared once every 1 to 2 years to kill enemies, diseases and pests lurking in ponds and silt. Quicklime can not only kill wild fish, frog eggs, tadpoles, aquatic insects, snails and algae moss that remain in fish ponds, but also kill microorganisms, parasitic pathogens and their resting spores. Clear lime pond with quicklime, if it is dry pond, 50 ~ 75 kg per acre; pond, 1 acre 1 meter deep water to apply 125 ~ 150 kg.
