The invention relates to a method for grafting chestnut trees, and belongs to the technical field of forest fruit tree grafting. The method for grafting Chinese chestnut trees uses a single bud green wood of Chinese chestnut as a scion, the scion and a stock are in side grafting. The shape of a side grafting notch on the stock is an inverted triangle, and the peak of the inverted triangle is provided with a lengthwise cutting extending downward.
