抄録

The influence of nutrient concentration on the uptake of each nutrient by butter head lettuce plants (Lactuca sativa L. 'Okayama Salad') was investigated by using a NFT system. The solution volume in the NFT system was maintained constant automatically by supplying deionized water. The nutrient uptake was calculated from the decreasing rate of the nutrient concentration in the system. The NO₃-N, PO₄-P and K uptake rates by the lettuce plant were relatively stable within a comparatively wide range of nutrient concentrations, i.e., the nutrient uptake rates were not influenced directly by the nutrient concentrations. When the nutrient concentration was above 1 me·liter^-1, the uptake rate of each nutrient was unaffected by its concentration. The high ratio of the apparent uptake rate of NH₄-N in comparison with other nutrients indicates a preferential uptake of NH₄-N. From the environmental and managerial point of view, nutrient concentrations in a hydroponic production system should be lowered.
