Abstract

Effective calcium (Ca) management is crucial for optimizing oil palm cultivation and enhancing crop yield. This study aimed to gain insights into the dynamics of Ca concentration, accumulation, exportation, immobilization, and recycling in various oil palm organs relative to plant age. The experiment was conducted at the Agropalma enterprise site in the northeastern region of Pará State, Brazil, evaluating seven plant age treatments: 2, 3, 4, 5, 6, 7, and 8 years old. Employing a completely randomized design with four replications. The results demonstrated an age-related increase in Ca concentration in petioles, rachis, arrows, male inflorescences, peduncles, and fruits. Furthermore, Ca accumulation exhibited an upward trend in all organs with progressing plant age. Notably, the study revealed an enhanced Ca use efficiency across all plant organs in correlation with the age of oil palm cultivation. These findings underscore the dynamic nutritional demands of oil palm, influencing Ca immobilization, cycling, and export throughout its developmental stages.

钙积累和利用效率的变化及其对整个油棕循环中的回收、固定和出口的影响

有效的钙（Ca）管理对于优化油棕种植和提高作物产量至关重要。本研究旨在深入了解钙在油棕榈各器官中的浓度、积累、输出、固定和循环的动态变化，以及与植株年龄的关系。实验在巴西帕拉州东北部的 Agropalma 企业所在地进行，评估了七个植株年龄处理：分别为 2 年、3 年、4 年、5 年、6 年、7 年和 8 年。采用完全随机设计，四次重复。结果表明，叶柄、轴、箭头、雄花序、花序梗和果实中的钙浓度随年龄增长而增加。此外，随着植株年龄的增长，所有器官中的钙积累都呈上升趋势。值得注意的是，研究表明，随着油棕种植年龄的增长，所有植物器官对钙的利用效率都有所提高。这些发现强调了油棕的动态营养需求，影响了钙在其整个发育阶段的固定、循环和输出。
