Abstract Black currant cultivation is in continuous expansion, with importance in human nutrition and a high degree of suitability for industrial processing. The nutritional, organoleptic, and pharmaceutical qualities of its fruits represent a great source of natural antioxidants, vitamins, and phenols. We have tested the specific reaction of three black currant varieties to foliar fertilizers in order to obtain two growth models. Each variety have a specific response to fertilizers. Application of Kombimax lead to the highest increase during the vegetation period and 72 cm length of branches at the end of vegetation period. Ascovigor and Mikromix produces 3–4 cm increases in branches length compared to control. N, K2O, and CaO from fertilizer recipe act synergically for the final development of branches. The growth model based on branches length at 14 days add 0.97 cm for each existent cm. The complex model of growth add 2.44 cm for each mg of CaO existent in fertilizer recipe. Linear regressions show a growth potential of 0.97 cm/1 cm of branches at 14 days.

黑醋栗对叶面肥的反应——品种生长动态建模

摘要 黑加仑种植规模不断扩大，对人类营养具有重要意义，且高度适合工业加工。其果实的营养、感官和药用品质代表了天然抗氧化剂、维生素和酚类的重要来源。我们测试了三个黑加仑品种对叶面肥的特定反应，以获得两种生长模型。每个品种对肥料都有特定的反应。Kombimax 的应用导致植被期的最大增加和72 cm 的植被期末的树枝长度。与对照相比，Ascovigor 和 Mikromix 使分支长度增加 3-4 厘米。肥料配方中的 N、K2O 和 CaO 协同作用，促进枝条的最终发育。基于 14 天树枝长度的生长模型为每个现有厘米增加 0.97 厘米。对于肥料配方中存在的每毫克 CaO，复杂的生长模型会增加 2.44 cm。线性回归显示 14 天时树枝的生长潜力为 0.97 厘米/1 厘米。
