现介绍两种清塘新法供大家参考。1、碳酸氢铵清塘法。具体方法是:水深1米,每亩用碳酸氢铵50公斤,全池遍洒,水温在25℃～30℃,一小时不到野杂鱼就会死亡。原因是碳铵施入池中,很快产生高浓度的氨,影响了鱼体内酶的催化反应和膜的稳定性,抑制鱼类鳃器官的正常呼吸机能,使之窒息死亡。2、漂白粉,尿素清塘法。具体方法是:在投放鱼苗前,每亩水面用尿素6公斤,兑水后泼洒,24小时后用漂白粉3公斤,溶水泼洒,水温在23℃～30℃时,半小时左右,野杂鱼即中毒
Now introduce two new law for your reference. 1, ammonium bicarbonate clear pond method. The specific method is: 1 meter deep, with 50 kg of ammonium bicarbonate per mu, all over the pool sprinkle, the water temperature at 25 ℃ ~ 30 ℃, an hour less than wild trash will die. The reason is that ammonium bicarbonate is applied to the pool, producing high ammonia quickly, affecting the catalytic reaction of the fish and the stability of the membrane, inhibiting the normal respiratory function of fish gill organs and causing asphyxia. 2, bleaching powder, urea Qing Tang method. Specific methods are: before the release of fry, per mu of water with urea 6 kg, watered spill, after 24 hours with bleach 3 kg, splashed water, the water temperature at 23 ℃ ~ 30 ℃, about half an hour, wild trash Poisoning
