Although it has been reported that Ti-ascorbin promotes the growth of crops (see the above-mentioned book by Marc Jakovlevich Skorinik), how titanium is specifically involved in the growth of crops is described. There is no literature that quantitatively shows it, and there is no example in the field of crop cultivation that actually reports the results of applying Ti to the yield.

It has been proposed to reduce nitrogen fertilizer and use organic fertilizer.
However, nitrogen fertilizer reduction is difficult to implement in the field because it reduces the yield, and organic fertilizer may have a higher nitric acid content in vegetables than chemical fertilizer (nitrogen) depending on the type of organic matter and the application rate. However, organically grown vegetables are not safe.

て本発明を完成するに至った。DISCLOSURE OF THE INVENTION In view of the fact that titanium oxide has attracted attention in the field of photocatalyst in recent years, it is considered that titanium may be involved in the growth of crops utilizing sunlight, The effect of titanium on the growth of crops was studied thoroughly. That is, as an aqueous solution of a water-soluble titanium compound which is easily absorbed by crops, titanium was absorbed from the leaves or roots of the crops, and the relationship between chlorophyll production in the crops, nitric acid content in the crops and sugar content of the crops was studied. As a result, by applying a trace amount of a water-soluble titanium compound to a crop, the amount of chlorophyll produced in the crop increases and the photosynthetic reaction becomes vigorous, the nitric acid content in the crop body considered to be a carcinogen decreases, and the sugar content (Brix ) The value increases. Further, it was confirmed that the sugar content (Brix) of the crop was increased, the shelf life was improved, and the quality of the product was increased, and the present invention was completed.

It can be seen that after 4 days, it increased by 6% and after 14 days it increased by 12%. Ti concentration 1.0p
The difference in the reaction between the pm group and the 3.3 ppm group after 4 days and 6 days is considered to be due to the amount of Ti absorption of azimina. It is considered that even at 1.0 ppm, the chlorophyll value will increase due to absorption over time.

向がみられないのは、供試野菜が収穫中後期で生育低下
時期のためと推定される。[0023] From Table 3, 3 Foliar treatment crop co titanium increases the chlorophyll value, nitrate in the leaves (NO 3 -) concentration to be reduced, the once sprayed twice spraying treatment, chlorophyll value Although there is no constant tendency for the increase in the amount of nitric acid, it can be seen that the nitric acid (NO 3 − ) concentration is obviously lower in the two times of spraying and the denitrification is remarkable. The reason that no constant tendency was observed between the two-time application and the one-time application of the chlorophyll value is presumed to be due to the growth decline period of the test vegetables in the middle of the harvest.

への助援効果など広範な用途が期待される。As described above, it was revealed for the first time that water-soluble titanium exhibits an effect comparable to that of conventional molybdenum (Mo) in enhancing chlorophyll production. The crop growth promoter according to the present invention is used as an agricultural material excellent in the low nitrification of vegetables involved in the carcinogen nitrosamine, and by the healthy growth of the crop due to the decrease of the nitric acid content, the reduction of pesticide cultivation, the increase of the amino acid and sugar content. It is expected to have a wide range of uses such as a supporting effect for improving food quality and yield.
