摘　　要：【目的】不同苹果产区的果园土壤养分水平之间并不完全相同,甚至存在较大的差异,为此,对苹果主产区土壤养分状况进行具体分析对指导生产有一定实际意义。【方法】该研究以晋中太谷苹果园土壤为研究对象,分析比较了4个乡15个苹果园土壤中pH值、有机质、碱解氮、土壤有效磷、速效钾、全氮的营养状况。【结果】结果表明:太谷区苹果园土壤养分整体较好,均达III级标准以上。其中,有机质含量较高,不同果园的有机质含量变异也较大。说明在苹果园的管理中,果农对有机肥的投入水平比较重视,但不同苹果园的有机肥投入水平也不相同。土壤pH值的变异系数较小,仅有1.85%,但其余土壤养分各因子含量的变异系数较大,均超过30%。【结论】太谷区不同苹果园之间,土壤养分含量差异较大。结合苹果园的具体情况分析,土壤养分状况与果农个体经营方式密切相关。【Objective】There are great differences on soil nutrient levels in different apple orchards.It is of practical significance to analyze the soil nutrient status in main apple producing areas.【Methods】The nutrient status of pH,organic matter,alkali~hydrolyzed nitrogen,soil available phosphorus,available potassium and total nitrogen of 15 apple orchards from 4 townships were analyzed and compared in Taigu,Jinzhong.【Results】The results showed that the soil nutrients of apple orchards in Taigu were better and their level were grade III even better.Among soil nutrients,the organic matter content was higher and there was geret differences in different orchards.It indicated that fruit farmers payed more attention to the input of the organic fertilizer in the management of apple orchards,but the input of organic fertilizer was different in every apple orchards.The variation of soil pH was the smallest,only 1.85%,and that of soil nutrient factors was larger than 30%.【Conclusion】The results indicated that soil nutrient content varied greatly among different apple orchards in Taigu.The soil nutrient status was closely related to the individual management of fruit farmers analying the specific situation of apple orchards.
