The trellis pear tree cultivation technology is a high-quality and high-end pear management technology introduced to my country from Japan in recent years. The height of the main branch of a large tree is required to be controlled at about 1.6 meters, with 2 to 3 side branches left on both sides of the main branch. This article mainly introduces the structural materials and scaffold installation of scaffold cultivation. The shaping and pruning is mainly based on the scaffold structure.

(1) Scaffold structural materials

① Ground anchor hook: 12 mm × 1300 mm steel bar, with a 4 cm buttonhole made on the upper part and a 40 cm cross welded on the lower part. ② Inclined pole: Made of reinforced concrete, 300 cm × 12 cm × 10 cm. ③Upright pole: Made of reinforced concrete, 180 cm × 8 cm × 8 cm. At the top of the pole, leave 5 cm of steel bars exposed. When erecting the ceiling, lay down the steel bars and fix them. ④ Use 6 strands of No. 10 steel strands for the peripheral rope, 5 strands of No. 12 steel strands for the main line, and use No. 10 steel wire for the middle auxiliary line. ⑤Connector buckles: Use large buckles for the surrounding lines and medium buckles for the main lines. ⑥ Weight plate: inclined rod weight plate is 30 cm × 30 cm × 10 cm, vertical rod weight plate is 20 cm × 20 cm × 6 cm.

①Anchor pit: 70 cm × 60 cm × 120 cm. Use 150 kilograms of concrete to fix the ground anchor hooks to the soil under the pit, one every 5 meters around the perimeter. ②Scaffold height: 180 cm from the roof to the ground. ③ First, set up two oblique vertical poles at each corner, and set up an oblique vertical pole every 5 meters around the corner, with an angle of 45°. Hang the diagonal pole vertically corresponding to the ground anchor hook, and then tighten the surrounding ropes and the main line of the shed surface. Finally, pull a secondary line every 80 cm. ④After the shed surface is completed, the main line is jacked up with main poles every other way, and the ceiling surface of each pole is 100 meters 2.
