Cover crops in vineyards do provide many important ecosystem functions, however wine growers are often reluctant to incorporate cover crops into their vineyard management as they are concerned about competition regarding water and nutrient availability. The objective of this study was to define the effects of three standard inter-row vegetation management strategies on vine growth and grape quality in different European regions. We hypothesize that general patterns of responses to different inter-row management can be identified across European vine growing regions independent of local climate and soil conditions. Data were collected in 2016 and 2017 in commercial vineyards located in five European temperate wine growing regions directly comparing standard inter-row vegetation management strategies in parallel in vineyards ranging from cover crops to bare ground through tillage or herbicide application. Vegetation management strongly influenced leaf chlorophyll content, shoot pruning weight and yeast assimilable nitrogen (YAN) in grape juice. Across countries, grape varieties and varying soil conditions, YAN consistently showed higher values in grapes separated by bare ground inter-rows as compared to inter-rows with a permanent vegetation cover. Other grape quality parameters, total soluble solids, total titratable acidity and berry weight were not or inconsistently affected across countries, preventing the prediction of generalized trends. We also observed higher values of soil organic matter in complete vegetation inter-rows. In conclusion, we identified general effects of inter-row vegetation management on vine vigor and grape quality across countries and grape varieties in different pedo-climatic conditions. Our study provides general response patterns as a basis for functional studies to develop local inter-row vegetation management strategies.

影响欧洲葡萄园葡萄活力和葡萄品质的不同行间植被管理的总体趋势

葡萄园中的覆盖作物确实提供了许多重要的生态系统功能,但葡萄种植者通常不愿意将覆盖作物纳入他们的葡萄园管理,因为他们担心水和养分供应方面的竞争。本研究的目的是确定三种标准行间植被管理策略对不同欧洲地区葡萄树生长和葡萄质量的影响。我们假设可以在欧洲葡萄种植区确定对不同行间管理的一般反应模式,而不受当地气候和土壤条件的影响。数据是在 2016 年和 2017 年在位于五个欧洲温带葡萄酒产区的商业葡萄园中收集的,直接比较了葡萄园中的标准行间植被管理策略,从覆盖作物到裸地,通过耕作或除草剂应用。植被管理强烈影响葡萄汁中的叶绿素含量、枝条修剪重量和酵母可同化氮(YAN)。在不同的国家、葡萄品种和不同的土壤条件下,与具有永久植被覆盖的行间相比,裸地行间分隔的葡萄的 YAN 值始终较高。其他葡萄质量参数、总可溶性固形物、总可滴定酸度和浆果重量在各国之间没有或不一致地受到影响,妨碍了对普遍趋势的预测。我们还观察到完整植被行间土壤有机质的更高值。总之,我们确定了行间植被管理对不同土壤气候条件下不同国家和葡萄品种的葡萄活力和葡萄质量的一般影响。我们的研究提供了一般响应模式作为功能研究的基础,以制定当地的行间植被管理策略。
