In the early spring, solanaceous vegetables and melons grown in greenhouses were planted in greenhouses more than in winter. Grafting and raising seedlings is a commonly used seedling raising method in the production of protected vegetables in recent years. There are three points to note.
Choose the right rootstock
Different rootstocks have great differences in drought tolerance, cold resistance, disease resistance, etc., and the corresponding rootstocks can be selected according to the purpose of cultivation and cultivation methods. Such as cucumber grafted seedlings in winter, you can choose low temperature, good stretch of Yunnan black pumpkin as rootstock.
Choose the right method
There are grafting methods such as plugging, splicing, and grafting. Plugging and docking are performed before and after the breakage of the seedlings and are mainly applied to melon vegetables. Among them, the scion is small and the hypocotyl is finely used for plugging; the scion seedlings, the thickness of the hypocotyl and the rootstock are similar to each other, such as cucumber and pumpkin grafting. The splicing is carried out when the rootstock is very large, even when mature, and it is mainly used for vegetables such as eggplants.
Determine the time of sowing
The timing of rootstock and scion sowing depends on both the growth characteristics and the grafting method to be used. For example, cucumbers and black squash should be sowed 5 to 7 days earlier than cucumbers when they are grafted by grafting. When using grafting methods, cucumbers should be sown 5 to 6 days earlier than sunspotted squash.
