METHOD FOR PREDICTING ABSORPTION AMOUNT OF HEAVY METAL IN CROP, ABSORPTION INHIBITING TECHNIQUE, AND ABSORPTION INHIBITING APPARATUS EACH USING THE METHOD

Japanese Patent JP3912198

B2

PROBLEM TO BE SOLVED: To provide a method for predicting an absorption amount of heavy metal in harvested crops in cultivation, predicting the concentration of heavy metals, a technique for inhibiting absorption of the heavy metal, and an apparatus for inhibiting absorption each applied based on the prediction.
SOLUTION: The method for predicting absorption amount of heavy metal contained in produced crops comprises predicting the concentration of the heavy metal in the soil in a term from a panicle formation stage to a ripening period and the concentration of the heavy metal in the stalk part of the crop in a term from a heading stage to a milk-ripe stage based on the result of analysis, using a correlation calculating method. The technique for inhibiting absorption comprises at least one technique of that for regulating the pH value of a planted area, that for regulating dissolved rate of the heavy metal, and that for inhibiting absorption of dissolving heavy metal.
