The invention discloses a planting method of plateau mine herbaceous plants, comprising the following steps of: preparing soil, seeding, and spraying a nutrient solution, wherein the nutrient solution comprises the following components in proportion: 0.5L of original mixing liquid, 0.5L of water and 100g of water-retaining agent and the original mixing liquid comprises the following components: 1650mg/L of NH4NO3, 1900mg/L of KNO3, 370mg/L of MgSO4 7H2O, 170mg/L of KH2PO4, 440mg/L of CaCl2 2H2O, 0.83mg/L of KI, 6.20mg/L of H3BO3, 22.30mg/L of MnSO4 4H2O, 8.60mg/L of ZnSO4 7H2O, 0.25mg/L of Na2MoO4 2H2O, 0.025mg/L of CuSO4 5H2O, 0.025mg/L of CoCl2 6H2O, 28.70mg/L of FeSO4 7H2O, 37.3mg/L of Na2-EDTA 2H2O, 100 mg/L of inositol, 0.5mg/L of niacin, 0.5mg/L of pyridoxine hydrochloride, 0.1mg/L of thiamine chloride, 2mg/L of glycine and 25g of sucrose; covering soil; and covering mulching film. Through the implementation and the usage of the method, the germination rate and the survival rate and the per-plant tiller number of elymus dahuricus turcz can be greatly increased, therefore, the possibility of recovering vegetation of mines is increased.
