Abstract:: Taking first-filial generation cucumber variety of ‘Qingwa Wangzi ’ as material，in venlo greenhouse，with bags of perlite as the carrier，and the Hoagland nutrient solution for fertilization，T1(1∶200),T2(1∶100),T3(1∶50),T4(1∶30)four treatments were set，and the destructive experiments was conducted，during the whole growth period of cucumber，and determine potassium (K)content in cucumber organs.In order to study K uptake of cucumber organs grew in greenhouse under different nutrient solution concentrations.The results showed that，with the increase of the concentration of nutrient solution,the potassium uptake of the organs of greenhouse cucumber increased gradually.But when the nutrient solution concentration was higher than T3,greenhouse cucumber production was reduced.When the nutrient solution concentration was T3，greenhouse cucumber yield was the highest，reached 6 984.499 g per plant.
