ESPALIER VINEYARD

ESPALIER VINEYARD

VIGNETO SPALLIERA

This system consists of a vertical trunk where a fruit shoot of 8-10 buds in length is folded horizontally along the row; the 1-2 gem basal spur is used for the renewal of the following year. Pre-stressed concrete posts are used and positioned at a distance of no more than 6 meters. In case of iron posts, the same must not exceed intervals of 5 meters in-between each other and they must be planted at a depth of 70 to 80 cm in the ground, while the above ground part must be of at least 170-180 cm in length. The vertical trunk is 80 to 100 cm high and the fruit head is leaned on a “supporting” wire of 2.00 to 3.15 mm, depending on the material used. One or two pairs of wires, positioned at a distance of about 30-40 cm, are positioned above the “supporting” wire: they will be used to collect the plants by making them continue on developing upwards. In some cases, a wire can be positioned at the end of the post to give the shoots an additional support (usually at a height of 1.80 m). Further bud growth can be controlled by polling. Mechanization can be applied with good results: shoot polling, shoot binding and harvesting can be done easily, while winter pruning cannot be mechanized: in fact, the fruit shoot would break the following year.

Characteristics

  • optimal system density
  • (3,500 – 5,000 plants per hectare)
  • simple structure
  • optimal foliage exposure
  • good quality production
  • good level of mechanization
  • indicated for vines with low basal productivity

Type of installation:

  •  Bigger supporting wire (Ø 2 ÷ 3.15 mm) positioned at 0.8 ÷ 1 m
  •  Wire retaining smaller vegetation (Ø 1.6 ÷ 1.8 mm) positioned at 30 cm from the supporting wire
  • Shoot supporting wire on the top of the post and 70 – 80 cm from the supporting wire
