Grape protected cultivation generally has small space and high planting density. The commonly used shelves are hedges and sheds. Hedges mainly include single-wall hedges, shed hedges and T-frames, and sheds include inclined sheds and roof sheds. At present, there are three kinds of greenhouse grape trellis in China: inclined shed trellis, hedge trellis and V-shaped hedge trellis, and some other trellis shapes are formed by adjusting and improving these three trellis shapes.

(1) single-wall fence frame. Generally, the row spacing is 1.5-2.5 m, the plant spacing is 0.5- 1 m, and the frame height is1.2-1.8m. Set a column every 4-6 m in each row, and pull a wire on the column every 40-60 cm. The advantages of single-wall hedge frame are good ventilation and light transmission conditions, convenient field management, close planting and early harvest. Disadvantages are strong polar growth, improper control, easy upward movement of fruiting part, and close ear to the ground, easy to be infected with pests and diseases and contaminated by soil.

(2) scaffolding fence. Generally, the row spacing is 2.5-3.5m, the plant spacing is 0.5- 1.5m, and the frame height is 1.2- 1.8m, that is, the low pole height is 1.2m, and the high pole height is 1.8m.. The side is a hedge frame. This kind of frame is actually a deformation of the shed frame, which has the advantages of ventilation and light transmission, early fruiting and high yield.

(3) "T-frame. Generally, the row spacing is 2.5-3m, the plant spacing is1-1.5m. The height of the frame is 1.6 ~ 1.8m, with a beam with a length of 0.6 ~ 1.0m at the top and another beam with a length of 0.3 ~ 0.4m the bottom. The new shoots and fruiting branches are tied to the wire on both sides respectively. This kind of frame has good ventilation and light transmission, light disease and convenient management.

(4) Inclined small scaffolding. General row spacing is 3-4m, plant spacing is 0.5- 1.5m, shelf heel height 1.2- 1.5m, shelf tip height 1.6-2m, and shelf length is generally 4-5m. The advantage is that the main vines are easy to control and enter the fruiting period earlier.

(5) Roof scaffolding. Generally, the row spacing is 3-4m, the plant spacing is 0.5- 1.5m, the heel height 1.2- 1.5m, and the tip height1.5-2.0m. The size of the shelf surface depends on the width of the greenhouse, and grape plants generally climb to both sides.
