Abstract
ABSTRACT Agronomic and chemical parameters of chokeberry (Aronia melanocarpa) with respect to the effects of different rates of fertiliser and of net shading were evaluated in a plantation that was in the fifth and sixth year of cultivation. Two commercial organic fertilisers, Fertor and Siforga, were applied at four rates (0.5, 1.0, 1.5, and 2.0 t ha−1), and shading was applied with two types of green polyethylene shading nets, retaining 30% and 50% of sunlight, respectively. Among the pomological characteristics, the clearest difference was observed for the number of clusters, which, in the second year, was significantly increased by both factors. The number of clusters was shown to have the highest correlation with the yield of berries. In the first year, only the higher rates of fertilisation affected the yields, but in the second year, the yields were significantly increased by all of the fertiliser treatments, compared with the control. For metabolic parameters such as dry matter, soluble solids, titratable acidity, sugars and ascorbic acid, the effects of the treatments were inconsistent. Only the highest rates of the fertilisers and the dark net had significant positive effects on the total phenolics. The concentrations of hyperoside in fruit from the shaded shrubs were significantly higher than in the control, with a similar pattern also for isoquercetin, but only for the dark net. Concentrations of the other individual phenolic compounds differed only slightly.
摘要在种植第五年和第六年的人工林中,评估了不同施肥率和净遮荫效果下的黑果Aronia的农艺和化学参数。两种商业有机肥料Fertor和Siforga以四种速率施用(0.5、1.0、1.5和2.0 t ha−1),并使用两种类型的绿色聚乙烯遮荫网进行遮荫,分别保留30%和50%的阳光。在果树学特征中,观察到集群数量的差异最为明显,在第二年,这两个因素都显著增加了集群数量。聚类数量与浆果产量的相关性最高。在第一年,只有较高的施肥率会影响产量,但在第二年,与对照相比,所有施肥处理的产量都显著增加。对于代谢参数,如干物质、可溶性固体、可滴定酸度、糖和抗坏血酸,处理的效果不一致。只有最高施肥率和暗网对总酚类物质有显著的积极影响。遮荫灌木果实中金丝桃苷的浓度显著高于对照,异槲皮素也有类似的模式,但仅限于暗网。其他单独酚类化合物的浓度仅略有不同。
期刊介绍:
Biological Agriculture & Horticulture aims to act as the central focus for a wide range of studies into alternative systems of husbandry, and particularly the biological or organic approach to food production. The Journal publishes work of a sound scientific or economic nature related to any aspect of biological husbandry in agriculture, horticulture and forestry in both temperate and tropical conditions, including energy and water utilization, and environmental impact.
