(1) Natural joy has no obvious central trunk, and there are 3-4 main branches on the trunk, 6-8 lateral branches on each main branch, each with fruit branches, and the center of the crown is transparent. The base angle of the three main branches is 45 ~ 50, and the angle of the main branches outside 1 m should be gradually reduced, that is, the waist angle should be 30. The angle of the top of the main branch, that is, the sharp angle, should be close to upright, and the plant is about 4 meters high.

The advantages of this tree shape are good ventilation and light transmission, strong skeleton, suitable for close planting, small main branch angle and slow aging. Suitable for varieties with strong growth potential and no open main branches. The disadvantage is that the young trees are heavily pruned, enter the fruiting period late, the main branches are erect, and the lateral branches are difficult to cultivate.

(2) The horizontal grid scaffolding is 2m high, the trunk is 80- 100 cm high, and there are 2-4 main branches, with the interlayer distance of 60cm, which are evenly distributed and extend to the rows. The spacing of main branches on the grid is1.5-2.0m. The main branches are not equipped with side branches, but with large, medium and small branches on both sides. The distance between big branches is 80 cm, the distance between middle branches is 30 ~ 40 cm, and the distance between branchlets is 10 ~ 20 cm. As a result, the branches are evenly distributed on the surface of the shelf. There are no large branches on the back of the main branch.

The tree has the advantages of convenient daily management such as bagging, spraying, fertilizing and harvesting. The crown is not high and the branches are firm, which can reduce wind damage and mechanical damage; Trees have good light, stable fruits and good quality. Disadvantages are large investment in framing, time-consuming management fees, high requirements for fertilizer and water conditions, and large pruning of young trees.
