Sesto d'impianto per l'uva da tavola: segreti per una migliore crescita radicale

In questo video, io Giuseppe Cacucci, agronomo di Upgrape, ti parlo dell'importanza di allargare l'impianto dei vigneti. Grazie alla diminuzione della densità di impianto, infatti, si favorisce la crescita dell'apparato radicale delle piante e la diffusione della luce. Ciò comporta vantaggi sia dal punto di vista produttivo che agronomico.
Con una maggiore distanza tra le piante, infatti, si evita la competizione tra gli apparati radicali e si favorisce la produzione di sostanze nutritive per le uve. Inoltre, le piante sono in grado di intercettare più luce, sviluppando una superficie vegetale più ampia e limitando l'ombreggiamento reciproco.
Tutti questi processi sono fondamentali per garantire una buona maturazione delle uve.

It is common in the design of new vineyards, to widen the planting, that is, the distance between the plants. Let’s see why. I’m Giuseppe Cacucci agronomist Upgrape, a social communication project about table grapes.
Today I am on a farm that I am following. In this case we have a distance between the plants in a north-south direction of 2,7 m, in an east-west direction of 3 m. In this case we have a planting density of 1235 plants per hectare.
One of the fundamental aspects that has decreased the density of planting in our vineyards is variety innovation.
In fact, part of the varieties that have developed in our territory has a vigour that needs for growth and development, a greater space than what would be created instead in the usual vineyards that we are used to see. Without necessarily to talk into the detail of the variety, adopting wider planting has advantages from the production point of view and also from the agronomic point of view.
One of the fundamental aspects is the growth of the root system. As the distance between the rows increases the volume of soil available for root growth will not be affected by the competition effects of the root systems of neighbouring plants, developing on a different soil without sharing the same space. It would develop an equally vegetative system proportional therefore to the volume of the root that would be able therefore to produce substances of nutrition for our grapes. Finally we will have well-developed plants that will not compete with each other.
Another aspect to consider is the diffusion of light. Adopting wider implants means giving our plants the possibility to intercept more light. These conditions the plants would develop a vegetal surface on a larger space with limited mutual shading conditions that instead are created when we use narrower implants.
Therefore, during the production year we will have a good diffusion of light in these conditions and therefore we will guarantee a whole series of metabolic processes including ripening. Let us remember that in the vineyard it is important to ensure an indirect and not direct light diffusion, because the direct light on the plant tissues, therefore on the tissues of the berries, would increase the temperature up to 30°C, limit value that would interfere the synthesis of anthocyanins and all those processes of color formation and maturation that would be delayed, especially for that portion of grape that is exposed directly to light radiation.
In the next video we will continue to talk about advantages of choosing to adopt larger plantations. Keep following me on Facebook, Instagram and RUclips.
