摘要

咖啡杯质量的决定因素变化很大,取决于它们与咖啡生产和效益的相互作用。本研究旨在分析土壤和气候因素及其与Nariño部门220A和221A生态型生产单位3 - 5年卡斯蒂略咖啡品种杯品质的关系。研究农场分布在海拔≤1500 m、1501 ~ 1700 m和>1700 m 3个不同的海拔范围。通过主成分分析和聚类分析对土壤、气候和咖啡杯质量变量进行分析。气候和土壤营养因素与咖啡杯质量之间的关联程度较低。土壤锰、铁、铜含量与杯子品质的相关性最高,平均得分为80.89。La Unión - Nariño的光合有效辐射par和热幅值最高,这些变量与获得最高杯质评分(82.58)的组相关。杯子质量与海拔无关,因为最高分数(85.5和82.33)分别来自位于≤1500 m.a.s.l和>1700 m.a.s.l的生产单位。

Environmental offering and coffee cup quality (Coffea arabica L.) Var. Castillo in southern Colombia
The determinant factors of coffee cup quality are highly variable and depend on their interaction with coffee production and benefit. This study aimed to analyze soil and climatic factors and their association with the cup quality of Castillo coffee variety of three to five years of age from production units in ecotypes 220A and 221A of the Department of Nariño. The study farms were located in three different altitudinal ranges: ≤1500 m, between 1501 and 1700 m, and >1700 m. Soil, climate, and coffee cup quality variables were analyzed through principal component analysis and cluster analysis. A low level of association was found between climatic and soil nutritional factors and coffee cup quality. Soil Mn, Fe, and Cu contents showed the highest association levels with cup quality, indicated by an average score of 80.89. The highest values of photosynthetically active radiation -PAR- and thermal amplitude were found in La Unión - Nariño, and these variables were associated with the group that obtained the highest cup quality score (82.58). Cup quality was not associated with elevation since the highest scores (85.5 and 82.33) were obtained from production units located at ≤1500 m.a.s.l. and >1700 m.a.s.l, respectively.
