[0010] Implementation 1
[0011] The technical solution of this embodiment is:
[0012] Step 1: Step 1: Put potassium iodide into the water at a weight ratio of 100:0.5:0.2:0.1 according to the weight ratio of water, potassium iodide, iodine, and biologically active organic iodine. While stirring and heating, it is heated to 70°C and dissolved to Transparent, regarded as A solution.
[0013] The second step: according to the weight ratio of water, citric acid, and sodium hydroxide of 100:10:4.5, put the citric acid and sodium hydroxide into the water and stir to dissolve, which is the B solution.
[0014] Step 3: Take 45° concentrated seaweed juice, the concentration is calculated by salinity, according to the volume ratio of seaweed juice, A solution, B solution 10:8:10, add seaweed juice, B solution to A solution in turn, mix Evenly, it becomes a fungicide for iodine-rich soil.
[0015] Field comparison test: In 2004, we set up two plots in the vineyard, each plot is 666m 2 , Respec...
