Vine trainingとは 意味・読み方・使い方

The use of vine training systems in viticulture is aimed primarily to assist in canopy management with finding the balance in enough foliage to facilitate photosynthesis without excessive shading that could impede grape ripening or promote grape diseases. Additional benefits of utilizing particular training systems could be to control potential yields and to facilitate mechanization of certain vineyard tasks such as pruning, irrigation, applying pesticide or fertilizing sprays as well as harvesting the grapes. In deciding on what type of vine training system to use, growers will also consider the climate conditions of the vineyard where the amount of sunlight, humidity and wind could have a large impact on the exact benefits the training system offers. For instance, while having a large spread out canopy such as what the Geneva Double Curtain offers can promote a favorable leaf to fruit ratio for photosynthesis it offers very little wind protection. In places such as the Châteauneuf-du-Pape, strong prevailing winds such as le mistral can take the fruit right off the vine so a more condensed, protective vine training system is desirable for vineyards there.
