The invention provides a spraying method of leaf calcium fertilizer for a peach tree. The spraying method comprises the following steps: (A) preparing the calcium fertilizer form the following components in parts by mass: 30 to 40 parts of a calcium source, 5 to 10 parts of acetic acid, 4 to 5 parts of a natural glycol solution, 10 to 15 parts of an amino acid and 20 to 30 parts of a trace elementsubstance, wherein a ratio of N to P2O5 to SiO2: to K2O in the calcium fertilizer is (1 to 2): (0.2 to 0.4): (0.2 to 0.4): 0.5; (B) preparing the calcium fertilizer into a solution with a calcium fertilizer concentration controlled at 0.3 to 0.5 weight percent, and repeatedly spraying the solution for 2 to 3 times. According to the spraying method of the leaf calcium fertilizer for the peach tree, by the adoption of the calcium fertilizer elaborately prepared by the inventor, the calcium fertilizer is sprayed by controlling the concentration of the calcium fertilizer; after the implementationof the whole spraying pro
