使用硫酸铜时必须注意以下事项:
Attention must be paid to the following matters when using copper sulfate:
(1) 硫酸铜的毒性与水温成正比,因此一般应在晴天上午使用效果较好,依水温相对减少用量;
(1) The toxicity of copper sulfate is directly proportional to the water temperature, so it should be used in sunny morning, and the dosage should be reduced according to the water temperature;
(2)硫酸铜的用量与水体肥度、有机物和悬浮物含量、盐度、PH值成正比,因此在使用过程中要视池塘的具体情况选择适当的用量;
(2) The amount of copper sulfate is directly proportional to the water fertility, organic matter and suspended solids content, salinity and pH value. Therefore, the appropriate amount of copper sulfate should be selected according to the specific situation of the pond;
(3)水体呈碱性时慎用硫酸铜,以免形成氧化铜毒死鱼类;
(3) When the water body is alkaline, copper sulfate should be used carefully to avoid the formation of copper oxide toxic dead fish;
(4)硫酸铜对鱼类等水生动物的安全浓度范围较小,毒性较大(尤其对鱼苗),因此在使用时应准确计算用量;
(4) The safe concentration range of copper sulfate to fish and other aquatic animals is small, and the toxicity is high (especially for fish fry), so the dosage should be calculated accurately;
(5)溶解时勿用金属器皿,勿用60℃以上的水,以防失去药效,投药后应充分增氧,防止死亡藻类消耗氧气,影响水质,导致泛塘;
(5) When dissolving, do not use metal utensils or water above 60 ℃ to prevent losing efficacy. After dosing, oxygen should be fully increased to prevent dead algae from consuming oxygen, affecting water quality and causing flooding;
