摘  要：
在延安、铜川、渭南、咸阳和宝鸡5个地区,选择树龄9~15 a的优质果园采集0~40 cm土壤作为样品,分析土壤中的有机质、全N、全P、碱解N及速效P、速效K和有效Fe、Mn、Cu、Zn的含量。结果表明:不同地区之间果园土壤养分含量差异较大,延安地区果园土壤全氮含量属于缺乏水平,有机质、碱解N、有效Fe、Mn、Zn含量都处在适宜范围的底线水平,铜川地区有效Mn含量处在适宜范围的底线水平;渭南和咸阳地区有效Fe和有效Mn含量都处在适宜范围的底线水平;宝鸡地区各养分指标含量都在适宜及以上水平。今后这些地区的果园在管理和施肥方面除了补充各自所缺的元素,还应考虑增加土壤有机质的含量,有机无机肥配合施用,并适当增加微肥的喷施量。

摘  要：
Determination of soil nutrients in the apple production regions of Weibei highland will provide fundamental reference for the scientific management and sustainable development of the apple industry in future.Soil samples were collected from Yan'an,Weinan,Tongchuan,Xianyang and Baoji areas in Weibei highland where high-quality apple planted.The ages of apple trees in the orchards were from 9 to 15 years and the soil organic matter,total N,total P,available N,P,K and available Fe,Mn,Cu and Zn were determined.The result showed that there was a significant difference in soil nutrients between the orchards in Weibei highland.The content of total N was in the deficient level,the contents of soil organic matter,available N,available Fe,available Mn and available Zn were at the bottom of suitable range in Yan'an area;the content of available Mn was at the bottom of suitable range in Tongchuan area;the contents of available Fe and available Mn were at the bottom of suitable range in Weinai and Xianyang areas;the contents of soil nutrient were more and then the suitable range in Baoji area.So some measures should be also taken to improve soil organic matter and available trace elements content,especially mixed use of organic manure and inorganic fertilizer,besides complementing elements which were scarce in different areas in future.
