(1) Regular sector pruning of hedge frame
North-south, row spacing 1.3 ~ 2.5m, plant spacing of 0.5m, 600 ~ 1020 plants per mu.
(2) Horizontal pruning of hedge frame
The row direction is north-south, the row spacing is 1.3 ~ 2.5m, the plant spacing is 1m, and 330 ~ 5 10 plants per mu.
(3) carrying out fan-shaped pruning on the fence frame without the main vines
The row direction is north-south, the row spacing is 2.0 ~ 3.0m, the plant spacing is 0.6m, and there are 2 plants in each hole, with 1 100 plants per mu.
(4) Y-shaped pruning of hedge frame
The row direction is north-south, the row spacing is 2.8 ~ 3.0m, the plant spacing is 0.6m or 1.2m, and each hole 1 plant can be pruned by two rods from the base. Plant 300 ~ 700 plants per mu.
(5) The inclined scaffold is trimmed by single dragon trunk.
Grapes cultivated in plastic greenhouse run north-south, with a distance of 1 row from the side of the greenhouse 1.0m, with a spacing of 0.5-0.6m The slope of the scaffold surface and the framework of the greenhouse gradually increases from outside to inside, and 300-400 grapes are planted per mu. Grapes planted in solar greenhouses run around here and there. Generally, only 1 ~ 2 rows are planted in a greenhouse, 1 m in front of the greenhouse, and planted in the middle of the greenhouse with a spacing of 0.5 ~ 0.6 m. The slope of the scaffold surface is consistent with that of the greenhouse skeleton. Because of the large line spacing and low early output, temporary lines can be set. With the coverage of permanent rows on the shelf surface, the generated area will increase, and temporary rows can gradually retreat and be eliminated. Therefore, 300 ~ 400 plants should be planted per mu in the early stage, and 150 ~ 200 plants should be planted in the later stage.
(6) H-shaped or X-shaped pruning of horizontal scaffolding
This is another form of scaffolding, which adopts horizontal H-shaped or X-shaped pruning of scaffolding. Generally, only 1 ~ 2 rows are planted in a greenhouse, and the row spacing is 0.5 ~ 1.0 m along the middle of the greenhouse. Cultivate vertical trunk in the first year, and gradually cultivate horizontal H-shaped or X-shaped trunk branches in the second and third years. This is a protected grape cultivation model popularized in recent years.
