Most pear trees cultivated in scaffolding are pleasing in shape. For example, Japan has fertile soil and relatively large annual growth, so a pear tree (Y type) with two main branches is selected in Japan. Y-shape is an ideal tree shape for pear varieties with many short branches, such as Niigata, Changshilang, Huangjin, Qiuhuangli and Fengshui. The selection of pear cultivation scaffolding should be based on varieties, climate, planting density and other factors. If the annual growth is small, 3 ~ 4 main branches can be cultivated in the early stage to accelerate the formation and early high yield, and then gradually transformed into two main branches. High-density cultivation mode (such as 3m× 3m) can adopt two main branches on the shelf, and low-density cultivation mode (such as 3m× 6m) can adopt three main branches on the shed. The height of seedlings is 0.7 ~ 0.9 meters. Choose three vegetative branches and tie them in three directions as the main branches. There are two side branches on each main branch, and there are fruiting branches on the side branches. The main branches and lateral branches are placed on the scaffolding at an angle of 45. The main branches remain short and strong, and the fruiting branches are cultivated by removing the core.
