Effet des couverts sur la flore en viticulture

Abstract : The spontaneous vegetation in vineyards is diverse and occupies an important spatial and temporal place. This vegetation is impacted by the different soil management practices and the pedoclimatic diversity of the vineyard terroirs. Its management is thought out according to the agronomic objectives of yield and quality, notably to limit competition with the vine. This management also responds to other ecological challenges: reduction in the use of herbicides, reduction in fossil fuel consumption, and the agro-ecological transition of winegrowing systems. In the "mixed" management method, which is often used, weed management in the inter-row is mainly based on mechanical weeding and/or grassing with mowing, while weeding in the row uses a chemical herbicide. In 2016, in France, inter-row weed control, whether partial or total, concerns 52% of the national vineyard area and varies greatly depending on the risk of drought and the density of plantation, which are decisive factors in the establishment and management of seeded cover. Among the many services, often linked to soil quality, potentially provided by these sown cover crops called service crops is the reduction of weeds by limiting their growth and development and inhibiting their germination. Finally, the management of spontaneous biodiversity within plots can satisfy other services such as the production of floral resources for pollinators or the production of biomass for grazing.
