Embodiment 1
[0018] A kind of tomato grafting method that can improve survival rate described in the present embodiment comprises the following steps:
[0019] (1) Choose wild tomato species with high resistance to bacterial wilt and root-knot nematode as rootstock, and use conventional varieties as scions. Before sowing, soak the seeds in warm water at 56°C for 4 hours, and then soak them in 40% trisodium sulfate 10 times solution for 15 minutes. , remove and clean germination;
[0020] (2) The rootstock was sown 8 days in advance, the rootstock was sown on-demand in sterile soil, the scion was sown on a flat border, and the scion was artificially planted in a nutrient bowl filled with nutrient solution for plant production 2 days before grafting;
[0021] (3) When the rootstock grows to 6 true leaves, it can be grafted. Use a blade to cut the rootstock stem 1.5cm below the cotyledons of the rootstock, remove the upper part, and cut it into a W shape on the stem plane. It is required that...
