The invention discloses soilless culture nutrient solution for leafy mustard. The soilless culture nutrient solution comprises, by weight, 0.5-1.5 parts of major elements, 0.002-0.01 part of trace elements, 0.05-0.5 part of active substances and 500-2000 parts of deionized water. A method for preparing the soilless culture nutrient solution includes preparing mother liquor A, mother liquor B and mixture C from the major elements, the trace elements and the active substances; mixing the mother liquor A and the mother liquor B with each other according to the weights of the major elements and the trace elements; adding the mixture C into the mother liquor A and the mother liquor B according to the weight proportion of the active substances; uniformly mixing the mother liquor A, the mother liquor B and the mixtures C to obtain the soilless culture nutrient solution. The soilless culture nutrient solution and the method have the advantages that requirements on diversified elements of the leafy mustard in growth p
