The invention discloses a cultivation method for improving firmness of tomato fruit. The cultivation method for improving the firmness of the tomato fruit comprises silico-calcium fertilizer fertilized on base, high-calcium high-magnesium fertilizer fertilized in a water flush mode and calcium magnesium fertilizer fertilized on leaf surfaces in an injected mode. The silico-calcium fertilizer fertilized on the base comprises the following steps: evenly broadcasting 30-50kg of the silico-calcium fertilizer in a solar greenhouse of 667 m before a tomato plant is planted, deeply ploughing to 20-30cm, mixing evenly, flatting, and ridging. The high-calcium high-magnesium fertilizer fertilized in a water flush mode comprises the following steps: when a second panicle fruit of the tomato plant grows to about 2-3cm, fertilizing 5-7.5kg of the high-calcium high-magnesium fertilizer in area of 667m. The calcium magnesium fertilizer fertilized on the leaf surfaces comprises the following steps: when a fourth panicle fruit of the tomato plant grows to about 0.3-0.5cm, using 150-200g of 36.2% of calcium nitrate magnesium fertilizer to add 45-60kg of water to spray on the leaf surfaces. By the adoption of the cultivation method for improving the firmness of the tomato fruit, high calcium level is benefited to maintain in a tomato fruit organization, firmness of the tomato fruit can be kept, respiratory rate is reduced, and ethylene is prevented from producing, so that the shelf-life of the fruit is prolonged, and commodity value of the fruit is improved.
