Abstract

This study aimed to investigate the impact of various plant nutrition applications and two pruning levels on the leaf mineral composition of grapevines (Vitis vinifera L. cv. ‘Ercis Uzumu’) cultivated under high-altitude conditions. The experiment, employing a randomized block experimental design with three replicates, includes a control group, and vines pruned to 30 or 40 buds, fertilized with poultry manure (PM), poultry manure + inorganic foliar fertilizer (PM + IFF), or poultry manure + organic foliar fertilizer (PM + OFF). Pruning significantly influences leaf mineral content, particularly phosphorus (P < 0.01), manganese (P < 0.05), and nickel levels (P < 0.05). Furthermore, fertilizer applications exhibit significant effects on phosphorous, magnesium, copper, iron, sodium, cadmium, chrome, and nickel levels (P < 0.01), with organic plant nutrition prominently enhancing leaf mineral content. Additionally, observations reveal higher ratios of P, K, Ca, and Mg in the 30 bud pruning per vine applications, as well as similar trends in micro-elements (Zn, Mn, and Cu) except for Fe. This research provides valuable insights into optimizing grapevine cultivation practices at high altitudes.

修剪和施肥对高海拔栽培葡萄（葡萄属）叶片矿物质成分的影响

本研究旨在探讨各种植物营养应用和两种修剪水平对高海拔条件下栽培的葡萄树（Vitis vinifera L. cv. 'Ercis Uzumu'）叶片矿物质成分的影响。实验采用随机区组实验设计，设三个重复，包括对照组和修剪至 30 或 40 个芽、施家禽粪便（PM）、家禽粪便+无机叶面肥（PM + IFF）或家禽粪便+有机叶面肥（PM + OFF）的葡萄树。修剪对叶片矿物质含量有明显影响，尤其是磷含量（P < 0.01）、锰含量（P < 0.05）和镍含量（P < 0.05）。此外，施肥对磷、镁、铜、铁、钠、镉、铬和镍的含量也有显著影响（P <0.01），有机植物营养显著提高了叶片的矿物质含量。此外，观察结果表明，在每株葡萄树修剪 30 个芽的情况下，P、K、Ca 和 Mg 的比率较高，除铁外，微量元素（锌、锰和铜）的趋势相似。这项研究为优化高海拔地区的葡萄栽培实践提供了宝贵的见解。
