GRAFTING METHOD AND JIG CLAMP FOR IMPLEMENTATION THEREOF Russian patent published in 2025 - IPC A01G17/02 A01G2/30 A01G7/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to viticulture. Method involves cutting of rootstock shoots at the height of a stem, a rootstock, preparation of a place for grafting in it, sanding with a knife a part of the graft to be placed in the place of grafting on the stock, connection of the grafted components and wrapping the compound with a polyethylene film. Before preparing the place for grafting, the stock is fixed with the help of a jig clamp containing a fixed jaw equipped with a handle and two guide bars, with a cut metric thread on one of them, and a movable sponge, having the possibility of moving along the tires and fixing between it and the fixed sponge of the vine stock with a wing nut. In the movable jaw at angle of 30° there is a through hole with a diameter corresponding to the diameter of the lower part of the graft handle sanded with a knife with a length in accordance with the length of the hole in the stock. Skinned part of the graft is inserted into the hole of the stock; for grafting, a thick stock and a one-eyed graft of the graft are used, which is set so that the eye of the graft is placed above the cut of the stock. Jig clamp in the form of a graft retainer contains a fixed jaw equipped with a handle and two guide rails, with a cut metric thread on one of them, and a movable jaw having the possibility of moving along the rails and fixation between it and the fixed sponge of the vine stock with a wing nut. In the movable jaw at angle of 30°, there is a through hole in which replaceable cylindrical guides are inserted for different diameters, in accordance with diameters of graft cuttings, drills, and jaws are made of rubber.

EFFECT: inventions provide higher quality of accretion in the place of rootstock and graft junction, reduced labour costs for preparatory processes of work with stock and graft handle and reduced risk of mechanical damages.
