| 简介 |
A method of cultivating agricultural crops by desalting deep sea water with an electrodialyzer or electric extractor, mixing agricultural water and supplying mixed water to crops is provided, which improves the crop yield and quality. Fertilizer is applied to fields; agricultural seeds are sown; and magnetized water is supplied to the agricultural seeds. The magnetized water is obtained by the steps of : mixing mineral water containing less than 500ml/L NaCl and agricultural water which is supplied to the range of electric conductivity of 150 to 300mus/cm while supplying agricultural water(ground water or river water) to a water storage tank(1) through a water level control valve; and subjecting to magnetization treatment with a magnetizer of a Nd-Fe-B based magnet of a rare earth element with a coercive force of 10, 000 to 30, 000 oersteds. The mineral water is obtained by electrodialysis or electric extraction of deep sea water using mono-valent cation exchange membranes and mono-valent anion exchange membranes. |
