告されている。Recently, nitric acid contamination of groundwater has become a problem, and at the same time, consumers are also interested in nitric acid contained in foods. The damage caused by nitric acid is methemoglobinemia, which is reduced in the human body to become nitrite, which binds to hemoglobin and cannot carry oxygen, and is reported as blue baby in the United States and Europe. It has also been reported that the same symptom also becomes a problem in cattle, and that dairy cattle fed with a feed in which a large amount of nitric acid is accumulated exhibit increased pulse and respiration, muscle spasms, and death in severe cases.

はこの考え方に限定されるものではない。The mechanism of action of the plant nitric acid reducing agent of the present invention has not yet been elucidated. A water-soluble molybdic acid compound is used as the plant nitric acid reducing agent. On the other hand, plant nitrate reductase contains molybdenum ions. If this enzyme does not work sufficiently, nitrate in the plant cannot be reduced and is accumulated. From this, the plant nitric acid reducing agent of the present invention contains molybdenum ions contained in nitrate reductase as a water-soluble molybdate compound, and further, the aqueous solution of the water-soluble molybdate compound is used alone as a plant. It had the effect of reducing the nitric acid content of. It is considered that there is an unclear mechanism of action due to the synergistic effect of the water-soluble molybdate compound and amino acids and nucleic acids. Of course, the mechanism of action of the plant nitric acid reducing agent of the present invention is not limited to this idea.

が判る。On the other hand, when the plant nitric acid reducing agent 2 of the present invention was used, the nitric acid content was lower than that of the non-sprayed product of Comparative Example 5,
It can be seen that nitric acid in spinach can be reduced without delaying growth. Further, it is clear that the nitric acid content is obviously smaller than that of the spinach in which the aqueous solution of ammonium molybdate and gelatin hydrolyzate of Comparative Example 6 was sprayed on the leaves.
