Description

Technical Field

[0001] This utility model relates to the field of citrus grafting technology, and in particular to a rootstock fixing device for citrus grafting seedling cultivation. Background Technology

[0002] Chinese patent document CN216874011U discloses a fixing sleeve for grafting fruit tree rootstock, including a connecting block. Fixing components are provided on both sides of the connecting block, and fixing plates are provided on the top of each fixing component. Two installation ropes, symmetrically distributed vertically, are provided on the left side of the right-side fixing plate. This fixing sleeve for grafting fruit tree rootstock utilizes a pull rod to move an isosceles trapezoidal plate downwards, causing a limiting rod to disengage from the movable groove and the mounting block. Simultaneously, the downward movement of the isosceles trapezoidal plate causes two wedge plates to move in opposite directions, resulting in the connecting rod pulling the movable block to stretch and compress a spring, which in turn causes the locking rod to disengage from the locking groove. This allows for the separation and fixing of mounting blocks at different positions, facilitating adjustment of the fixing sleeve size according to the different thicknesses and sizes of fruit trees. This enhances the stability of the fixing sleeve and improves the survival rate of fruit tree grafts.

[0003] The aforementioned fixing sleeve for grafting fruit tree rootstocks is not convenient for fixing the branches of the rootstock. The rootstock is prone to swaying significantly or even falling over when exposed to wind, which can easily damage the seedlings that grow from the scion and reduce the survival rate of the grafted fruit tree seedlings.
