长白山区不同酸性土壤上栽培越桔的树体营养状况研究

Nutrition Status of Blueberry Cultured on Various Acid Soil Types of Changbai Mountain Areas in Northest China

在长白山区选择４ 个土壤类型分别代表该区４ 个地区的土壤条件进行越桔栽培，供试品种采用“北空”、“美登”和“斯卫克”。栽培后４ 年内采叶片样本分析营养状况，结果表明，越桔叶片中营养元素含量因不同土壤类型而不同。叶片中Ｍｎ、Ｆｅ 含量在水湿地潜育土和草甸沼泽地土壤上很高；Ｎ、Ｐ和Ｋ 含量在暗棕色森林土和草甸沼泽地土壤上较高；Ｃａ 含量在暗棕色森林土壤上较高，Ｚｎ 、Ｃｕ 含量在水湿地潜育土上较高；Ｍｇ含量及土壤类型的影响较小。叶片中各元素含量在不同品种之间也有差异。

The results showed that leaf nutrient content of blueberry were influenced by various soil types. Leaf Mn, Fe were significantly high of blueberry cultured on meadow bog gleyed soil and meadow bog soil. Leaf N,P and K were higher of blueberry cultured on dark brown forest soil and meadow bog gleyed soil. Leaf Zn and Cu were higher of blueberry cultured on meadow bog gleyed soil. Leaf Mg was not inflenced by soil types. Leaf element content were different among 3 cultivars. According to the results of leaf nutrient, soil physical and chemical analysis, and the yield response of blueberry to various soil types, each of 4 soil types tested in this experiment could be a suitable soil type for blueberry culture properly administrated.
