Chapter 6 - Vineyard Management Flashcards
What are the main techniques used to manage the vine?
Training; Pruning; Trellising; Density
What is vine training?
Vine training typically refers to the shape of permanent wood of the vine.
What are the two broad categories of vine training?
Head Training; Cordon Training
What is Head Training?
These vines have relatively little permanent wood. Some only have a trunk, or a few short arms of permanent wood. They can be either spur-pruned or replacement cane-pruned.
What is Cordon Training?
These vines typically have a trunk with one or more permanent horizontal arms or “cordons”. The vines are usually spur-pruned. This technique makes machine harvesting easier to achieve.
What is vine pruning?
The removal of unwanted leaves, canes and permanent wood. It shapes the vine and limits its size. Pruning takes place every winter and summer.
What are the two types of winter pruning?
Spur; Replacement Cane
Explain spur pruning.
Spurs are short sections of one-year-old wood that have been cut down to only two or three buds. The spurs are either distributed along a cordon of permanent wood (cordon training) or around the top of the trunk (head training)
Explain Replacement cane pruning.
Canes are longer sections of one-year-old wood and can have between 8 and 20 buds. Typically only one or two canes are retained and each cane is tied horizontally to the trellis for support. Most often seen on head-trained vines. Also known as “Guyot” training.
What are trellises?
Permanent structures of stakes and wires that are used to support any replacement canes and the vine’s annual growth
Untrellised vines are suitable for mechanical harvesting. True or False?
False.
What is canopy management?
The use of posts and horizontal wires, to which the vine’s canes and shoots are tied.
What is VSP?
Vertical Shoot Positioning. The most widely used canopy management system.
What is Green Harvesting?
The removal of immature grapes shortly after veraison in order to manage the yield.
What are Nematodes?
Microscopic worms that attack the roots of vines interfering with water and nutrient uptake.
