摘要
以翼城县苹果园为例,探讨山西省翼城县农产品地理标志保护区内土壤肥力及空间分布特征。共采集翼城县果园土壤300份,测定12种土壤肥力相关指标,通过土壤肥力综合指数对土壤肥力进行综合评价和土壤肥力分级,借助SPSS 22.0软件、ArcGIS软件,统计并绘制土壤各肥力指标及土壤肥力综合值的空间分布趋势。结果表明,翼城县果园土壤中,全氮、碱解氮、有效磷、速效钾、有机质、有效硫、有效铜、有效锌、有效铁、有效锰、水溶硼和有效钼变异系数大小表现为有效硫(2.08%)<有效锰(6.51%)<有效铜(9.66%)<有效锌(10.00%)<有效铁(13.89%)<水溶硼(15.93%)<有效钼(19.16%)<有机质(26.87%)<全氮(37.58%)<碱解氮(40.92%)<速效钾(48.82%)<有效磷(110.39%)。果园土壤肥力分布范围为0.23~0.72,分为5个等级,以3级肥力区(0.35~0.40)和4级肥力区(0.30~0.35)为主,占比分别为35.12%、28.43%。
Taking the Yicheng apple orchard as an example to discuss spatial distribution characteristics of soil fertility for protective area of agro-product geographical indications.300 soil samples were collected from protective area.Twelve indicators of soil fertility and integrated fertility index can be evaluated and distributed by employing SPSS 22.0 and ArcGIS,including total N,available N,available P,available K,organic matter,available S,available Cu,available Zn,available Fe,available Mn,available B,available Mo.The coefficient of variation as follows:Available S(2.08%)<available Mn(6.51%)<available Cu(9.66%)<available Zn(10.00%)<available Fe(13.89%)<available B(15.93%)<available Mo(19.16%)<organic matter(26.87%)<total N(37.58%)<available N(40.92%)<available K(48.82%)<available P(110.39%).The integrated fertility index had been divided into five levels,ranging from 0.23 to 0.72,which dominated by 3th level(from 0.35 to 0.40)and 4th level(from 0.30 to 0.35),accounting for 35.12%and 28.43%,respectively.
