The method includes the following steps: dipping grapes in fruit expansion solution A on day 4 to 5 after the grapes flowering, wherein fruit expansion solution A is a mixed solution composed of gibberellin (GA3), zeatin (ZT), a 0 boron fertilizer and a plant extract； dipping the grapes in fruit expansion solution B on day 15 to 17 after the grapes flowering, wherein fruit expansion solution B is a mixed solution composed of forchlorfenuron (CPPU), thidiazuron (TDZ), a fruit beautiful agent, a dual reinforcing agent and an amino acid raw powder. The method disclosed herein is used for expanding fruit of grapes, the operation is convenient, and the fruit expansion efficiency can be improved； after 5 fruit expansion, the fruit set of grapes is great, after expansion of grapes grains, the grapes grains are uniform in size, and no crack occurs； moreover, the fruit wax of grapes is beautiful, the grapes have a good taste and a long storage time, and the fruit quality of the grapes can be improved well. -1-5 DRAWINGS )5 2 11 Figure 1 -1-
