The invention belongs to the technical field of crop cultivation, and particularly relates to a composite substrate cultivation nutrient solution of tomato, rock wool and coco coir. The composite substrate cultivation nutrient solution of tomato, rock wool and coco coir is characterized by being respectively prepared into a nutrient solution for an early stage of the bloom, a nutrient solution for 1-3 spike flower stages of the tomato, a nutrient solution for 4-5 spike flower stages of the tomato, a nutrient solution for 6-10 spike flower stages of the tomato, and a nutrient solution for 11-30 spike flower stages of the tomato according to different growth stages of the tomato. By adopting the nutrient solution disclosed by the invention, compared with the formula of a contrast nutrient solution, the tomato plant is robust, developed in root and upright in fruit; the yield per unit area is relatively higher than 3.5kg/m and can be up to 33.6kgm; the incidence of navel rot is relatively reduced by 10%; the upright degree of the fruit is high; the occupancy rate of the first-class goods fruit is relatively improved by 5%.
