Technical and Economic Efficiency of Vine Pruning: Results of Experimental Trials of Some Cultivars of Grapevine Grown in Sicily and Determination of Break-even Point

The research presents the results carried out on Sicilian viticulture in order to study the economic sustainability of the agricultural company. In particular, the author examined the operation of dry pruning and tying of the fruiting head in espalier vineyards with tools that facilitate the work. The economic analysis highlights that equipping yourself with mechanical tools that facilitate work is convenient for both large and small wineries. The results of the research highlight that the investment to facilitate pruning and tying in Guyot-trained vineyards can also be made by wine-growing companies and is increasingly convenient as the area under vines involved increases.

本研究呈现了针对西西里葡萄栽培开展的相关结果，旨在探究农业企业的经济可持续性。具体而言，作者考察了篱架葡萄园果穗的干剪枝与绑扎作业，所使用的工具可辅助提升作业效率。经济分析表明，配备辅助作业的机械工具对于大小型酒庄均具有经济效益。研究结果显示，居由式修剪葡萄园（Guyot-trained vineyards）中用于辅助剪枝与绑扎的投资，葡萄种植企业亦可承担；且随着所涉及的葡萄园面积扩大，该投资的经济效益愈发显著。
