在使用硫酸铜时的注意事项

[作者:aoutmy] [日期:17-06-07]
在使用硫酸铜时必须注意以下事项: The following items must be noted when using copper sulphate: (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 water temperature, so it is generally better to use the effect in the morning of sunny weather, and to reduce the amount of water 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 dosage of the copper sulfate with water, fertility, organic matter and suspended solids content, salinity, PH value is proportional to, so in use process depends on the specific situation to choose the proper dosage 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 alkalescent, the copper sulfate should be used with caution, so as not to form a dead fish of copper oxide; (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 of fish and other aquatic animals, such as copper sulfate, is smaller and more toxic (especially for fish), so it should be used correctly 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), dissolved when don't use metal utensils, do not use more than 60 ℃ water, in case of losing efficacy, coagulant dosage should be fully after aerobic, algae consume oxygen, prevent death affect water quality, causing extensive pond; (6)、硫酸铜有一定的毒副作用(如造血功能、摄食与生长等)和残留积累作用,故不能经常使用; (6). Copper sulfate has certain toxic side effects (such as hematopoiesis, feeding and growth, etc.) and residual accumulation, so it cannot be used regularly. (7)、治疗小瓜虫病、打粉病时切忌使用硫酸铜。 (7) the use of copper sulfate is not used when treating small melon bug and powdery disease.
