What is the single hedge structure of the vine?

The structure of the single fence frame is that a fence wall is set on one side of the tree row, the frame is upright, and the height is about 100 ~ 200 cm, and the column pulls 1 ~ 4 wires near the tree. The specific application of shelf height and silk number depends on the variety, tree shape, climate, soil and so on. When the variety has strong growth potential, complex tree structure, warm and humid climate and fertile soil, the rack can be higher and the number of silk lanes can be slightly higher. On the contrary, the frame can be lower and the number of stitches can be slightly less. The simplest single-wall fence frame is only 100 ~ 120 cm in height, and only one wire is pulled. In shaping and pruning technology, double-branch pruning and short-branch and long-stem pruning can be adopted. Therefore, the vines can be allowed to droop naturally without being tied. This kind of rack is more material-saving, more convenient and labor-saving in management, and is suitable for brewing and drying varieties with less strict requirements on the appearance of fruit ears.

; For fresh varieties with certain requirements on the appearance of the ear or areas with serious diseases, the shelf surface should be raised appropriately and two iron wires should be set with a spacing of 40 ~ 50 cm. As a result, the mother vine (or dragon stem) is tied to the first wire, and as a result, the vine is tied to the second wire.

; Fan-shaped pruning with new tips tied vertically upward usually adopts overhead type with 3 ~ 4 wires. The main vine and the fruiting vine are tied to 1 ~ 2 wires respectively, and the fruiting vine is mainly tied to 3 ~ 4 wires. The spacing of iron wires is 40 ~ 50 cm.

The advantages of single hedge frame are good ventilation and light transmission, convenient field management, suitable for close planting and overwintering, and beneficial to early high yield and improvement of fruit quality. It is the main framework for cultivating fresh food species in current production.
