摘　　要：对黄河农场芦笋地土壤定点采样,并对其土壤养分状况进行分析,结果表明,在大部分土壤中,有机质、碱解氮和有效钾含量均处于中等偏下水平,有效磷处于极缺状态;微量元素中铜和铁处于中等水平,锰和锌比较缺乏。建议在黄河农场芦笋田施肥中加大磷肥的施用比例,同时要重视锰和锌等微量元素肥料的使用;另外施肥要稍深一些,这样有利于芦笋根系对养分的吸收。The soil samples were collected from the Yellow River Farm to tmderstand the soil nutrient feature of asparagus field. The results demonstrated that both soil OM and available K contents were medium, even low. The available P content in soil was deficient. There was a reasonable Cu and Fe content; whereas Zn and Mn contents of soll were low. Therefore we suggest that more P fertilizer application is necessary ; Mn and Fe application should not be neglected in Yellow River Farm. Further, fertilizer should be applied deeper for easy absorption by asparagus root.
