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%.2>2>
