| description | The invention discloses a method for reducing the potassium content of hydroponic vegetables through a potassium-free nutrient solution. A common nutrient solution is replaced with the potassium-free nutrient solution in 7-14 days before the hydroponic vegetables are harvested, and the hydroponic vegetables are continuously illuminated through red light and blue light of an artificial LED; the ratio of the red light to the blue light of the LED is 4:1; the illumination intensity is 250 [mu]mol.m.s; the illumination time is 12 hours; and the method is suitable for hydroponic vegetables under the artificial illumination environment. According to the method for reducing the potassium content of the hydroponic vegetables through the potassium-free nutrient solution, the advantage that the illumination environment is controllable is utilized, and the common nutrient solution is replaced with the potassium-free nutrient solution before the hydroponic vegetables are harvested, so that the potassium content o |
