Tomatoes, eggplants and other eggplant vegetables are continuously planted continuously, and soil-borne diseases such as bacterial wilt, wilt and nematodes have occurred seriously, often resulting in dead seedlings, reduced production or even production. The use of grafting to replace roots can effectively solve this problem. <br>This topic screened and compared the existing tomato and eggplant rootstocks on the market, and selected 5 rootstocks suitable for grafting tomato and 6 rootstocks for eggplant grafting. At the same time, it was determined that the most suitable grafting seedling age for tomato is 25-28 days. The most suitable grafting method is split grafting, which provides data support for tomato and eggplant grafting.

Tomatoes, eggplants and other eggplant vegetables continued to be replanted, green, withered and nematodes and other soil-borne diseases occurred seriously, often resulting in dead seedlings, yield reduction and even extinction;<br>This topic on the market has been the existing tomato and eggplant birch screening comparison, selected suitable for tomato grafting birch 5, eggplant grafting birch 6, while determining the most suitable grafting seedling period of 25-28 days, eggplant most suitable grafting method for the grafting method, for tomato and eggplant grafting to provide data support.

Tomato, eggplant and other eggplant fruits and vegetables continuous cropping, wilt, nematode and other soil borne diseases occur seriously, often resulting in dead seedlings, yield reduction or even no production; and grafting root replacement planting can effectively solve this problem.<br>In this paper, the existing tomato and Eggplant Rootstocks on the market were screened and compared. Five suitable rootstocks for Tomato Grafting and six rootstocks for eggplant were selected. At the same time, the most suitable grafting seedling age of tomato was 25-28 days, and the most suitable grafting method for eggplant was split grafting method, which provided data support for tomato and eggplant grafting.<br>
