为确定韭菜水培营养液的氮素水平，试验设置4、6、8、10、12（CK）、14、16 mmol·L-1共7个氮素浓度梯度处理，采用北京市农林科学院蔬菜研究中心研发的新型水培系统进行水培试验，通过对水培韭菜的生长指标、单株干质量及鲜质量、产量、生理指标以及营养品质等测定分析表明：适合用于水培韭菜的营养液氮素水平为8～12 mmol·L-1，其中以10 mmol·L-1氮素浓度的营养液水培韭菜其生长状况及产量最佳；12 mmol·L-1氮素浓度的营养液水培韭菜品质最优。

In order to determine the nitrogen concentration of nutrient solution suitable for hydroponic Chinese chives(Allium tuberosum Rottlerspreng)7 levels of Nitrogen concentration(4,6,8,10,12,14,16 mmol·L -1) were set up to study the relevant product by using a new type of hydroponic system developed by Vegetable Research Center of Beijing Academy of Agriculture and Forestry Sciences. The growth index,individual dry and fresh weight and yields,physiological characteristics and nutritional quality were studied. The results showed that 8-12 mmol·L -1 nitrogen concentration of nutrient solution are suitable for hydroponic Chinese chives. Among them,10 mmol·L -1 Nitrogen concentration treatment showed the best effect on hydroponic Chinese chives growth index and yields; and 12 mmol·L -1nitrogen concentration treatment showed the best quality of hydroponic Chinese chives.
