There are great differences in drought tolerance, cold resistance, and disease resistance among different rootstocks of suitable rootstocks, and the corresponding rootstocks can be selected according to the purpose and method of cultivation. Such as cucumber grafted seedlings in winter, can use low temperature, good stretch of Yunnan black seed pumpkin as rootstock.
Select the appropriate method of vegetable grafting methods are docking, splicing, docking and so on. Plugging and splicing are performed before and after breaking the seedlings and are mainly applied to melon vegetables. Among them, the scion seedlings are small and the hypocotyls are mostly used for plugging; the scion seedlings, the thickness of the hypocotyls and the rootstock are similar to each other by the method of connection. The splicing method is used when the rootstock is large or even mature, such as the eggplant and other vegetables.
Determining the timing of sowing for rootstock and scion should be based on the growth characteristics of both and the grafting method to be used. When cucumber and black-skinned squash are grafted by grafting, black-skinned squash should be planted 5 to 7 days earlier than cucumber; when grafting is used, cucumber should be sown 5 to 6 days earlier than black-skinned squash.
