C6 - Vineyard Management Flashcards
What is vine training?
Typically refers to the shape of permanent wood of the vine and can be split broadly into two categories: Head training or Cordon training.
What is the benefit of low-trained?
To benefit from heat retained by the soil.
What is the benefit of high-trained?
To avoid frosts.
Explain what is head training?
These vine has relatively little permanent wood. Some only have a trunk. Other have a few short arms of permanent wood growing from the top of the trunk. They can either be spur-pruned or replacement cane-pruned.
Explain what is cordon training?
These vine typically have a trunk with one or more permanent horizontal arms or ‘cordon’. The vine usually spur-pruned.
What is pruning and when does it take places.
Pruning is the removal of unwanted leaves, canes and permanent wood. It shapes the vine and limits its size.
Pruning will take place every winter and summer.
What is the purpose of winter pruning?
To determine the number and location of the buds.
What are the two type of winter pruning?
Spur and replacement cane.
What is spur?
Spurs are short sections of one-year-old wood that have been cut down to only two to three buds.
What is cane?
Canes are longer sections of one-year-old wood and can have anything between eight and 20 buds.
What is the purpose of summer pruning?
Summer pruning involves trimming the canopy to restrict vegetative growth and direct sugar production to the grape, rather than growth of shoots and leaves.
It can involve leaf stripping so that bunches of grapes have optimum exposure to sunshine.
