The water-soluble fertilizer includes the following components, in weight percentage: effective elements of N + P20 5 + K20: 40 wt%; water: 3 wt%; a secondary element of sulfur: 3 wt%; trace elements: 0.2 wt%; a plant growth regulator: 0.05 wt% to 0.10 wt%; and water-insoluble matters: 2 wt%. The fertilizer is a solid powder, with a pH of 3.2, a particle size 60 mesh, a water-solubility 98%, and a dissolution time at a mass concentration of 20%: 7 min. The fertilizer of the present invention combines the major, secondary and trace element nutrients and a plant growth regulator at an appropriate ratio based on the characteristics of nutrient supply in the soil of the Qaidam Basin and the law of nutrient demand of juvenile L. barbarum, and has high concentration, excellent water-solubility, complete nutrients and high utilization, which can be applied to L. barbarum along with water under drip fertigation conditions.
