Grafting method capable of improving disease resistance of eggplants

The invention relates to the technical field of plant grafting, and particularly discloses a grafting method capable of improving eggplant disease resistance, which comprises the following steps: black nightshade seedling culture, eggplant seedling culture, seedling stage management and grafting. According to the method, the black nightshade is selected from wild Huanglongshan, has the advantages of being high in growth speed and good in disease resistance, and can greatly improve the disease resistance and yield of plants as the rootstock; in the growth process of eggplants, the morbidity is high, particularly, verticillium wilt is serious, and when the verticillium wilt is serious, no harvest is caused, and the fundamental problem can be solved through grafting; the solanum nigrum seeds are large in quantity, easy to breed and high in budding rate; by spraying a special nutrient solution, the wound healing speed of grafting is greatly increased, and the healing effect is good; by adopting the sleeve graftin
