| 摘 要： | 【目的】研究新疆温宿县核桃和红枣果园土壤肥力水平,为核桃和红枣果园科学施肥和耕地地力提升提供参考依据。【方法】选取果园土壤盐分含量、有机质、全氮、碱解氮、有效磷、速效钾、有效铁、有效锰、有效铜、有效锌、有效硼、土壤质地和质地构型作为评价指标,综合用于层次分析、特尔斐法、模糊数学隶属函数模型评价温宿县核桃红枣园土壤肥力。【结果】温宿县核桃红枣园土壤肥力水平主要集中在中肥力和低肥力区,其中核桃园中肥力、低肥力区和极低肥力区分别占核桃园面积的45.65%、35.57%和11.91%;红枣园中肥力、低肥力区和极低肥力区分别占红枣园面积的46.55%、44.35%和6.29%。【结论】两类果园的土壤肥力水平属中低水平,有机质、氮素、磷素、有效性锰和锌缺乏是影响温宿县核桃和红枣果园土壤肥力水平主要障碍因子,应培肥地力提升土壤有机质含量,重视氮肥、磷肥的施用,补施微量元素锰肥和锌肥。

| Abstract: | 【Objective】 The objective of this study is to explore the status of soil fertility of walnut and jujube orchards in Wensu County in the hope of providing a reference for the scientific fertilization and the improvement of cultivated land fertility. 【Method】The soil salt content, organic matter, total N, hydrolyzed N, available P, available K, available Zn, available Mn, available Cu, available B, available Fe, soil texture and texture form were selected as evaluation indexes to estimate the soil fertility of walnut and jujube orchards in Wensu County, and hierarchy process, Delphi method and fuzzy mathematical membership function model were applied to carry out comprehensive analysis. 【Result】The soil fertility level of walnut orchards and jujube orchards in Wensu County was mainly concentrated in medium and low fertility areas. In walnut orchards, the area of medium fertility accounted for 45.65%, the area of low fertility accounted for 35.57%, and the area of very low fertility accounted for 11.91%. In jujube orchards the area of low fertility accounted for 46.55%, the area of medium fertility accounted for 44.35%, and the area of very low fertility accounted for 6.29%. 【Conclusion】The soil fertility level of the two types orchards was medium and low level,the organic matter, nitrogen, phosphorus, zinc and manganese might be the obstacle factors of the improvement of soil fertility in walnut and jujube orchards in Wensu County. So, it was strongly suggested that the soil fertility of the soil should be increased, the organic matter content of the soil should be increased, the application of the nitrogen fertilizer and the phosphate fertilizer should be paid attention to, and the trace element manganese fertilizer and the zinc fertilizer should be applied. |
