摘　　要：在不灭菌的土壤中,研究了不同马铃薯接种不同菌根对马铃薯养分吸收以及土壤中速效氮、磷、钾的影响,接种菌根,几乎所有处理花期植株氮磷钾含量都高于对照,马铃薯成熟期土壤中速效氮、速效磷总的趋势增加,速效钾全部增加,但不同组合之间存在差异。In the non-sterile soil, the influence of different VA Mycorrhizal that were inoculated on absorption of nitrogen, phosphorus and potassium of potatoes and the content of available N,P,K in soil was studied. Almost contents of N,P, K of potatoes were higher than that of CK;During mature period of potato,available N and available P had a increasing trend, available K all increased, but there were differences among different combinations.
