After the rootstock is clamped for the second time, the position between the rootstock and the stalk can be adjusted again to ensure accurate docking, and then the driving component connected to the control fixing device 24 is started, so that the support plate 241 can be moved between the first clamping member 212 and the second clamping member 222, thereby ensuring that the first clamping member 212 and the second clamping member 222 leave space for the support plate 241, and when the support plate 241 enters the interval between the first clamping member 212 and the second clamping member 222, it contacts the docked rootstock and stalk (refer to the attached manual for details). Fig.16 As shown, the positions of the rootstock and the scion are not shown in the figure), at this time, the joint surface of the rootstock and the scion is located in the middle position of the support plate 241;

[0066] Since the positions of the rootstock and the scion wood at the first docking are fixed, after the rootstock and the scion wood are docked with each other, the driving device can use the docking position as the coordinate origin without positioning. The coordinate origin is only used when the rootstock and the scion wood are docked, and is preset inside the central controller. The central controller inside directly locates the docking position and controls other actions.

[0067] Then, by starting the linear drive mechanism connected to the movable clamp 245, the movable clamp 245 clamps the film 243 and pulls it outward. During the pulling process, the brush 246 applies the nutrient solution on the surface of the film 243, and then the cylinder connected to the cutting knife 2473 is controlled to start, so that the cutting knife 2473 cuts off the clamping member 242; the cylinder connected to the starting feed block 2472 is started, and the feeding block 2472 conveys the clamping member 242 forward, and the clamping member 242 first contacts with the film 243 and pushes the film 243 to move forward. 243 is continuously pulled out from the storage box 244 until it contacts the docked stock and spicate, so that the stock and spicate and the film 243 are clamped into the clamping piece 242, and when the clamping piece 242 is loaded onto the stock and spicate, the cutting edge on the feeding block 2472 cuts off the excess film 243, and the excess film 243 can be stored in the storage box 244 again for secondary use, and the stock and spicate are docked and fixed, thereby completing the grafting (the position state of the spicate and the stock during the grafting process can be referred to in the attached figure). Fig.18 ).
