(1) frame fence frame can be divided into single-wall fence frame and double-wall fence frame, and single-wall fence frame is widely used.
(1) The single-wall fence frame is set with 1 column every 8 ~ 10 m along the row, with the total length of the column being 2.6 ~ 2.7 m, buried 50 ~ 60 cm underground and 2. 1 ~ 2.2 m higher than the ground, and pulled on the column every 40 ~ 50 cm. Line 1 is 50 ~ 60cm from the ground. Because of its heavy load, the thicker 10 line can be used, and the above wires are 40 ~ 45cm apart, and the 12 line can be used. The column can be a wooden column, a stone column or a cement column.
The double-wall fence frame consists of 65,438+0 single walls on both sides of the grape row, with the distance between the bottom of the double walls of 50-60 cm and the distance between the top of 80-65,438+0.20 cm. Cross beams are erected at the top of the pillars of the two walls, which are reinforced by wire traction to prevent them from leaning outward. In some places, in order to save frame materials, only a single column is set up, and a beam is erected on the column, and both ends of the beam are pulled by iron wires instead of double columns and double walls (Figure 6 1). Double-walled hedge frame with branches and leaves on both sides can effectively use light and space, increase the number of new shoots and fruit ears, and the yield is higher than that of single-walled hedge frame, but it requires higher fertilizer and water conditions, thicker soil, dense branches and leaves at the base, poor ventilation and light transmission, and is vulnerable to pests and diseases and soil pollution, which is inconvenient to manage. Not suitable for hot and humid areas.

(2) There are many kinds of small scaffolding, such as connected scaffolding, roof scaffolding, horizontal scaffolding, inclined scaffolding and funnel scaffolding.
(2) Small scaffolding often uses mixed pruning of long and short shoots of multiple main vines, or multiple short shoots of main vines, and the pruning method is similar to that of the large scaffolding introduced earlier. Hedge frame pruning usually adopts free fan-shaped pruning with mixed long and short tips of multiple main vines, hedge frame fan-shaped pruning and single main vine inclined pruning.
