Abstract

The selection of rootstocks is one of the first and most important stages in the establishment of grape plantations under grafted conditions, which determines the productivity of rootstock-scion combinations and the further chain of design solutions: spatial placement of rows on the land plot, accompanying the production process of agronomic and agrochemical methods. Given the high importance of terroir factors for viticulture and winemaking, we were aware of the need to consider them in detail at this design stage. The aim was to create an algorithm for selecting varieties based on local terroir factors and apply it to the design of vineyards. Based on the analysis of literary sources and the agronomic experience of viticulture and winemaking specialists, we have identified key stress factors that in general, should be taken into account when selecting varieties of rootstocks. Based on the results of a comprehensive study of terroir and analytical diagnostics of soil samples taken on a land plot located in the Bakhchisaray district of the Republic of Crimea, local stress factors representing risks were clarified and prioritized neo-medially at the site of testing the landscape-adapted approach to the selection of rootstocks: carbonate condition, risk of phylloxera infestation, high content of fine fractions in granulometric composition, short-term droughts, risk of local overwatering, phosphorus deficiency. In total 20 the most common commercial varieties of rootstocks were considered for each selected soil area. The sample reduction scenario, based on the prioritization of the above stressors, reduced the number of varieties considered to three variants: 1103 Paulsen, 140 Ruggeri, and Fercal, which were scored against each other and considering the local terroir conditions of the plot, for further comparison in terms of market and logistics in making the final design decision.
酿酒风土。不同特性土壤中葡萄砧木选择指南
砧木的选择是在嫁接条件下建立葡萄种植园的第一个也是最重要的阶段之一,它决定了砧木-接穗组合的生产力和进一步的设计解决方案链:在地块上的空间放置,伴随着农艺和农化方法的生产过程。考虑到风土因素对葡萄种植和葡萄酒酿造的高度重要性,我们意识到在这个设计阶段需要详细考虑它们。其目的是创建一种基于当地风土因素选择品种的算法,并将其应用于葡萄园的设计。根据文献资料的分析以及葡萄栽培和酿酒专家的农艺经验,我们确定了在选择砧木品种时应该考虑的关键压力因素。根据对克里米亚共和国巴赫奇萨赖地区一块土地的风土条件和土壤样本分析诊断的综合研究结果,明确了代表风险的当地压力因素,并在对砧木选择的景观适应方法进行测试的现场以新媒介方式优先考虑:碳酸盐条件,根瘤蚜侵染风险,颗粒成分中细组分含量高,短期干旱,局部过度浇水风险,缺磷。在每个选定的土壤区域,总共考虑了20种最常见的商业砧木品种。在样本缩减场景中,根据上述压力源的优先级,将考虑的品种数量减少为三个变体:1103 Paulsen, 140 Ruggeri和Fercal,并考虑地块当地的风土条件,相互评分,以便在最终设计决策中进一步进行市场和物流方面的比较。
