摘要
[目的]通过叶片分析探讨延边地区苹果梨的营养状况,为苹果梨树的营养诊断与合理施肥提供参考,使施肥措施合理化、有效化。[方法]在延边地区采集8个成年苹果梨园土壤、叶片样品进行养分分析。[结果]叶片各营养元素的含量随季节变化呈现有规律的变化。不同果园叶片各营养元素的变幅从大到小依次为Mn、Cu、P、Zn、Fe、K、N、Ca、Mg。[结论]延边地区土壤养分含量状况总体呈下降趋势,因此应重视有机肥的施用并适当增施氮磷钾肥。
[Objective]Through investigate the nutritional status by leaf analysis of Yanbian Pyrus bretschneideri Rehd.cv.‘Pingguoli’to provide reference for the nutritional diagnosis and rational fertilization to ensure fertilization rational and effective.[Method]8 orchards soil and leaf samples in Yanbian area were used to analyze nutrients.[Result]The content of each element changed with the seasons regularly.Variation range of different orchards for each nutrient elements： Mn 〉 Cu 〉 P 〉 Zn 〉 Fe 〉 K 〉 N 〉 Ca 〉 Mg.[Conclusion] The soil nutrient content of the Yanbian area condition overall was on the decline,so it should pay attention to applying organic manure and appropriately increasing NPK fertilizer.
