The method includes the steps that (1) a flexible water retention material is used for making a tomato sleeve pipe, and the diameter of the tomato sleeve pipe is matched with a tomato grafting stem; (2) a tomato grafting stock and scion are inclined-cut, and cut faces of the stock and the scion are matched with each other; and (3) the tomato sleeve pipe is sleeved on the cut position of the stock, the scion is inserted into the tomato sleeve pipe, and a grafting clamp is clamped on the tomato sleeve pipe to be fixed. The cut face of the stock and the scion are matched with each other, contact is close, the external tomato sleeve pipe is used for fixing the stock and the scion, a water retention effect of the flexible water retention material on the grafted tomato is good, and after the grafted tomato is grown, the flexible plastics can be cracked open along with the growth of the tomato and do not need to be removed.
