摘要: 目的】 研究评价果园土壤肥力状况,为科学施肥及土壤和作物营养诊断提供依据。【方法】 引入内梅罗指数法,并根据土壤肥力的“木桶理论”进行变形。采用隶属度函数和修正内梅罗指数方法,选取常规养分指标和微量元素共10个指标,对温宿县果园土壤肥力进行综合评价。【结果】 研究区土壤常规养分和微量元素养分的综合肥力贡献率分别为0.55和0.45;土壤综合肥力指数处于0.10~0.85,平均为0.39,整体处于中等偏低水平。【结论】 利用隶属度函数和修正内梅罗指数方法,建立的定量土壤肥力综合评价方法,突出了单项土壤肥力指标缺素情况,能够较好的揭示果园土壤肥力状况。

Abstract: Objective】 To better explain the actual situation of soil fertility in orchard in the hope of providing a basis for scientific fertilization and soil & crop nutrition diagnosis. 【Method】 This paper introduced the Nemero index method and modified it according to the"Wooden barrel theory"of soil fertility. The soil fertility of orchard in Wensu County was comprehensively evaluated by using the method of membership function and modified Neimero index method, and by selecting 10 indexes of conventional nutrients and trace elements.【Result】 The combined fertility contribution rates of soil conventional nutrients and trace element nutrients in the study area were 0.45 and 0.55, respectively; the soil comprehensive fertility index was between 0.10 and 0.85, with an average of 0.39, and as a whole, it was at a moderately low level. 【Conclusion 】 Using the membership function and the modified Nemero index method, the comprehensive evaluation method of quantitative soil fertility was established, which highlighted the deficiency of single soil fertility index and better revealed the soil fertility status of orchards.

Key words: modified Nemerow index; soil fertility evaluation; orchard soil
