When grafting twigs with a diameter of 1 to 4 cm on the main branches of the pear tree, an anvil with a diameter of 4 to 6 cm shall be cut and grafted using a single bud grafting method; the bald area without anvil piles should be single-budded. grafting.
Single bud cutting method. First scion on both sides of the bud slightly lower than the bud 0.3 to 0.5 centimeters cut into 2 to 3 centimeters long slope, cut at 0.5 centimeters on the bud, in the anvil stick cut a 2 to 3 cm incline below the incision Sprouts are quickly inserted into the incision and the scion is aligned with the forming layer of the anvil incision and a plastic film 0.005 mm thick, 15 cm wide and 40 to 60 cm long is used to cover the scion together with the anvil stake section and the interface at one end. Live, pay attention to the interface and the plastic film to tighten the tightness, and then twist the remaining film into a rope, and tighten the interface. In addition, under the bud, a circle around the incision; the film covering the outside of the bud is tightened on the bud. Finally put the rope head tightly in the rope loop.
Single bud abdominal connection method. Firstly, a 3-cm-wide chisel knife is used to cut a vertical knife-edge perpendicular to the branch in the direction perpendicular to the branch from the grafting site, and then the blade is advanced 3 to 4 centimeters from the knife-edge, and the second horizontal knife-edge is cut parallel to the first horizontal knife-edge. It is also deep in the xylem, and the bark is gently picked up with a knife to lift it. Scion on the back of the bud is slightly lower than the bud 0.2 to 0.5 centimeters, cut into 3 to 4 centimeters of slope. The scion was cut at 0.5 cm of the bud and the bud was inserted outwards in the bark of the interface. With a width of 15 to 20 cm, a thickness of 0.005 mm film tightly sealed. When tying, buds are only covered with a single layer of film, and the interface of the bud (along with the scion) is covered with a layer so that the buds can rupture when growing.
