First, the well-dissolved copper sulfate solution is first injected into the milk of lime to allow the reaction to proceed in an alkaline medium, using a dense copper ash method.
Secondly, prepare milk of lime with 1/10 of the water, and add 9/10 of water to the copper sulphate solution. Then slowly pour the copper sulphate solution into the milk of lime and stir while pouring, or pour the two solutions into the third barrel at the same time. In the middle, stirring while stirring. Do not pour lime milk into the copper sulphate solution, otherwise it will cause precipitation, reduce the efficacy, and it is easy to produce phytotoxicity after use.
Finally, insert a moment with polished nails to avoid copper plating.
