The invention discloses a perforation type double-end bridge joint method for diseased bergamot
pear trees, and belongs to the field of bridge joint of bergamot
pear trees. The method includes the steps of 1, selecting bridge joint trees; 2, making bridge joint preparation, wherein wounds are treated, scions are collected, and bridge joint time and bridge joint positions are selected; 3, carrying out
grafting operation, wherein the scions 10-15 cm longer than the wounds are selected and covered with films in a winding mode, parts 5-10 cm longer than joint intervals are
cut away, ends are
cut in to a
wedge shape,
cut faces are made smooth and flat, wedge-shaped joints are chiseled out at
grafting positions, the wedge-shaped joints reach deep to
xylem by 0.5-1 cm, the width of the wedge-shaped joints is matched with that of the scions, edges are cut to be neat, the scions are inserted into the joints at the corner of 15-30 degrees and fixed in an arch shape without displacement or
dislocation, the joints are tightly wrapped till airtightness is achieved, and
moisture is ensured; 4, spraying a protective agent, and preventing the scions form being touched; 5, removing the films after healing. The perforation type double-end bridge joint technology for the bergamot
pear trees is created, so that the
survival rate of the diseased trees reaches 95%, the fruit setting rate is significantly increased, the fruit quality and the
disease resistance are significantly improved, and the survival time is significantly prolonged; the perforation type double-end bridge joint technology for the bergamot pear trees is suitable for popularization.
