抄録

The present research was carried out to obtain necessary data for effective uses of deep seawater in hydroponics of vegetables. NaCl was removed from deep seawater by electrodialysis using a selective membrane cartridge for exchange of monovalentions. The electrodialyzed deep seawater in an electric conductivity range of 5 to 25dS/m was then used to prepare nutrient solution for hydroponics of spinach. The yield and contents of nutritional compounds of spinach were investigated.<br>Experimental results showed that for the electrodialyzed deep seawater, potassium and sodium concentrations could be expressed as linear functions of electric conductivity in the range of 10 to 50dS/m. Saline obstacle to the growth of spinach was negligible if deep seawater was electrodialyzed to an electrical conductivity below 16dS/m and then diluted with deionized water to 10 times in volume. The highest yield of spinach was obtained when deep seawater was electrodialyzed to 5dS/m. In the case that deep seawater was electrodialyzed to 10dS/m and then 11 times diluted, spinach had almost the same contents of protein, crude ash and reduced vitamin C as that related to deionized water.
