- 摘要:
- 以黄瓜品种‘青瓜王子’杂交一代为试材，在Venlo型玻璃温室中，以袋装珍珠岩为载体，以霍格兰（Hoagland）营养液进行施肥，设置T1（1∶200）、T2（1∶100）、T3（1∶50）、T4（1∶30）4个处理，对黄瓜整个生育期进行破坏性试验，测定黄瓜各器官钾的含量，以研究不同浓度营养液下温室黄瓜各器官对钾吸收的规律。结果表明：随着营养液浓度的提高，温室黄瓜各器官对钾的吸收量逐渐增多，但当营养液浓度超过T3时对温室黄瓜产量不利，T3处理对温室黄瓜的产量最有利，达6 984.499 g/株。
- 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.
