Embodiment 1
[0035] A method for growing seedlings by grafting tomato, said method comprising the steps of:
[0036] S1, seedling pretreatment
[0037] a. Rootstock preparation: Select the eggplant seedlings cultivated in the 98-hole cultivation tray. The height of the eggplant seedlings is 20-30cm, with two leaves and one heart or three leaves and one heart. For the eggplant rootstock, spray cytokinin on the eggplant rootstock, spray until the plants are wet, and graft after 2 hours; the cytokinin is purchased from the market.
[0038] b. Tomato seedling preparation: cut the cultivated tomato seedlings into scion seedlings containing 3 to 5 true leaves, and set aside;
[0039] S2. Casing grafting: prepare the grafting sleeve, the grafting sleeve is a plastic hose, the pipe height is 0.6m, and the pipe diameter is 2.5cm; insert the lower end of the tomato scion seedling to the middle of the sleeve, and then insert the sleeve The other end of the other end is socketed on the eggplant root...
