NOVELTY - Cultivating functional agricultural product, comprises e.g. cultivating far infrared rays plant nutrient by storing aging raw material containing rice, rice-washed water, green onion, chungyang red pepper, onion and ginger in an aging tank, radiating with far infrared rays, adding far infrared rays salt and far infrared rays sugar, aging, diluting obtained plant nutrient in water, sprinkling manure, compost and fertilizer on wheat field, impregnating seed by diluting in water, and radiating light of red, yellow and blue color at constant intervals in the core.    USE - The product is useful for preventing diabetes (claimed), and as insect repellent, bacteria prevention agent and nutritional supplement for promoting blood circulation and clearing blood.    ADVANTAGE - The method is economical and environmentally friendly, increases the income of farmers and sugar content of the fruit, improves the quality of the product, and preserves freshness and color of the product. The product warms the body up to greater than or equal to 1 degrees C, maintains health, promotes digestion and absorption of nutrients.    DETAILED DESCRIPTION - Cultivating functional agricultural product, comprises either: (a1) cultivating far infrared rays plant nutrient by storing the aging raw material containing 10-25 wt.% rice, 10-20 wt.% rice-washed water, 10-20 wt.% green onion, 10-20 wt.% chungyang red pepper, 10-20 wt.% onion and 10-20 wt.% ginger in an aging tank, radiating with far infrared rays, adding 10-20 wt.% far infrared rays salt and 10-20 wt.% far infrared rays sugar based on the total weight of the aging raw material, and aging for 10-15 days, (b1) diluting the obtained plant nutrient in 17-19 l water to 10-20 cc, and sprinkling manure, compost and fertilizer on wheat field, (c1) impregnating seed by diluting in 17-19 l water, radiating light of red, yellow and blue color at constant intervals in the core, heat-treating elvan or rare earth metal within a mineral storage tank provided with a radiating unit, and germinating by radiating nano-powder having size of 20-60 nm with light for 60-80 minutes using a far infrared rays active device, (d1) sprouting the leaf surface for 3 days by diluting the plant nutrient in 17-19 l water to 10-20 cc from the germinated seeds, radiating light of red, yellow and blue color at constant intervals in the core, and seedling for installing the far infrared rays active device by heat treating egg plant, (e1) installing the far-infrared rays active device equipped with a water tank pipe for facing red, yellow and blue color wavelength lights, diluting the plant nutrient in 17-19 l water to 10-20 cc, transferring by diluting the pesticide, and supplying the pesticide, (f1) diluting the plant nutrient in 17-19 l water to 10-20 cc by harvesting the agricultural product, and washing by impregnating for 8-10 minutes; or (a1), (b1), (c2) radiating light of red, yellow and blue color at constant intervals in the core, installing the far-infrared rays active device equipped with the water tank pipe for facing the red, yellow and blue color wavelength lights diluting the plant nutrient in 17-19 l water to 10-20 cc, transferring by diluting the pesticide, and supplying the pesticide, (d2) mounting far-infrared rays active device and the at an inlet port of a housing, and (f1).
