使用硫酸铜注意事项
在使用硫酸铜时必须注意以下事项: In the use of copper sulphate, we must pay attention to the following items: (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 proportional to the temperature of water, so it should be used well in the morning of sunny day, and the amount of water temperature should be reduced relative 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 body fatness, organic matter and suspended matter content, salinity and pH value. Therefore, the appropriate dosage should be selected according to the specific conditions of the pond during the operation. (3)、水体呈碱性时慎用硫酸铜,以免形成氧化铜毒死鱼类; (3) copper sulfate is used carefully when the water is alkaline, so as not to form the dead fish of copper oxide poison. (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) copper sulphate has smaller safety concentration for fish and other aquatic animals, and is more toxic (especially for fish fry). Therefore, the amount of copper should be accurately calculated when used. (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) do not use metal utensils, when dissolved, not more than 60 DEG C water, to prevent the loss of efficacy, dosage should be sufficient oxygen, prevent the death of algae consume oxygen, affect the water quality, resulting in the pond.
