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.

本研究围绕西西里岛葡萄栽培（Sicilian viticulture）展开，旨在探究农业生产经营主体的经济可持续性，并呈现了相关研究成果。具体而言，本研究借助辅助作业工具，对篱架葡萄园（espalier vineyards）的冬季修剪（dry pruning）与结果枝组绑缚作业流程开展了系统考察。经济分析结果表明，配备辅助作业的机械工具，无论对于大型还是小型酒庄（wineries）均具备显著的经济性优势。研究结果同时显示，针对居由式整形葡萄园（Guyot-trained vineyards）实施修剪与绑缚辅助作业的投资，同样可由葡萄种植企业开展，且随着涉及的葡萄种植面积扩大，该投资的经济性优势会愈发凸显。
