Take Bali as an example. Bali is dry and upright, and the shape of young trees should be transformed from spindle to sparse trunk year by year. There are more main branches, 1 layer has 3 ~ 4 main branches, and the second layer has 2 ~ 3 main branches, and the interlayer spacing can be appropriately reduced.

Young trees should pay attention to pulling branches and opening corners, and carve injuries to promote branches. After entering the fruiting stage, the main branches of the second layer can be reduced by 1 ~ 2. Pears in Bali have many buds and branches, so the requirements for light are not high, and the branches can be properly kept dense. In order to prevent the main branch opening angle from being too large and easy to form branches on the back, the opening angle of the main branch should be 40.

Take back the big branches in the big year, and leave more middle branches in the small year. Long, medium and short fruit branches have good fruiting, and branchlets don't need to be updated in a hurry.
