%X The effects of different cutting-roots and K top-dressing measures at later growth stage on K concentration in leaves of flue-cured tobacco plants were studied. The results demonstrate that cutting-root and increasing application of K can stimulate the formation of new roots and then their uptake activity. Considering both the K content and the leaf dry weight, the best measure is cutting-roots on the position 20 cm away from the stem base and simultaneously the top-dre- ssing with K_2SO_4 when plants are decapitated.
