The invention provides a method for improving potato and tomato grafting survival rate. The method comprises the following steps: selecting a potato as a rootstock and selecting a tomato as a scion, and cultivating a seedling of the scion 30 to 60 days before that of the rootstock; remaining the stubble of a young seedling of the potato rootstock with the height of 10 cm, and removing all branches, buds and leaves; when the young seedling of the tomato scion grows to 20 to 25 cm, bevelling from the basal part of a stem of the young seedling at 45 degrees, and taking the tomato scion; treating the tomato scion for 30 minutes by using an activated formula, and grafting; transversely cutting the potato rootstock at the position of 10 cm, inserting the tomato scion into a notch of the potato rootstock after the centre of the notch is cut vertically, and fixing by using a grafting clamp to complete grafting; cultivating the grafted tomato seedling at the temperature of 25 to 28 DEG C and the air humidity of 70 to 95 percent. According to the method for improving the potato and tomato grafting survival rate provided by the invention, the stereoscopic cultivation yield benefit of an over-ground vegetable and an underground vegetable can be multiplied; the potato and tomato grafting survival rate is improved from 16.7 percent to 86.0 percent; the production cost is reduced by 68 percent or above; industrialization of a tomato and potato grafting technology is realized.
