[0092] like Figure 3 , 4 As shown in FIG. 7 , a fourth embodiment of the present invention provides a melon grafting method, which uses the above-mentioned melon seedling grafting device to graft melon seedlings, and is characterized in that it includes the following steps:

[0093] Step S1: Take a rootstock seedling, and insert the tip of the grafting bamboo stick 1 into the base of the rootstock seedling. The insertion position of the tip of the grafting bamboo stick 1 is located between one of the cotyledons of the rootstock seedling and the true leaf of the rootstock seedling.

[0094] Step S2: Slide the carrying plate 21 to the tip of the grafting bamboo stick 1 and position the carrying plate 21.

[0095] Step S3: Turn over the scabbard 321 , clamp and fix the true leaf between the head end of the scabbard 321 and the carrier plate 21 , and position the scabbard 321 .

[0096] Step S4: The driving blade 33 extends outward from the tip of the scabbard 321 , and the tip of the blade 33 cooperates with the tip of the grafting bamboo stick 1 to cut off the true leaves.

[0097] Step S5: Take a scion and use the blade 33 to cut off part of the lower embryonic foot of the scion.

[0098] Step S6: Pull out the grafting bamboo stick 1, and form a rootstock insertion hole at the insertion position of the grafting bamboo stick 1.

[0099] Step S7: inserting the lower embryo foot of the scion into the rootstock insertion hole.

[0100] When the user uses the device to implement the plug-in grafting method on the rootstock seedling, the user inserts the tip of the grafting bamboo stick 1 into the base of the rootstock seedling so that the insertion position of the tip of the grafting bamboo stick 1 is located between one of the cotyledons of the rootstock seedling and the true leaf of the rootstock seedling. Then, the user pushes the carrying plate 21 to slide it along the length direction of the grafting bamboo stick 1 to the insertion position of the tip of the grafting bamboo stick 1. After the carrying plate 21 moves into place, the user flips the scabbard 321 so that the head end of the scabbard 321 cooperates with the carrying plate 21 to clamp the rootstock seedling. The true leaves of the seedlings; thereafter, the user tightens the first hand screw 246, and uses the first supporting plate 21 and the second supporting plate 21 to clamp the grafted bamboo stick 1, so as to position the supporting plate 21. In the process of the user tightening the first hand screw 246, the second assembly plate 242 gradually approaches the third assembly plate 243. In the process of the user tightening the first hand screw 246, the end face of one end of the transmission shaft 247 is fitted with the side wall of the third assembly plate 243, and the first positioning The protrusions 2471 are respectively inserted into a plurality of first positioning grooves provided on the third assembly plate 243 to position the transmission shaft 247 to prevent the transmission shaft 247 from turning over due to external force; next, the user pushes the handle 323 to drive the head end of the blade 33 to extend through the head end port of the scabbard 321, so that the blade 33 cooperates with the grafting bamboo stick 1 to cut off the true leaves of the rootstock seedling; thereafter, the user pushes the handle 323 to move toward the rear end of the scabbard 321, and withdraws the blade 33 from the rear end port of the scabbard 321. At the same time, the user takes a melon seedling, i.e., a scion, and uses the blade 33 to cut off part of the embryonic foot of the scion obliquely downward, and ensures that the cut surface shape of the embryonic foot of the scion is wedge-shaped. After that, the user inserts the blade 33 back into the inner cavity of the scabbard 321 through the tail end port of the scabbard 321, and pulls the grafting bamboo stick 1 off the stock seedling, so that the tip of the grafting bamboo stick 1 forms a stock socket at the insertion position on the stock seedling. Finally, the user inserts the embryonic foot of the scion into the stock socket, thus completing the grafting process of the scion and the stock seedling.
