摘　　要：通过对黄河农场芦笋田土壤定点采样及其养分含量测定,结果表明:大部分土壤pH值偏高,有机质含量低,氮、磷、钾储备不足,速效氮和有效钾含量均处于中等偏下水平,有效磷为极缺状态。微量元素中铜和铁是中等水平,锌、锰和硼比较缺乏。阳离子代换量低,土壤保肥能力差。The soil samples were collected in the Yellow River Farm to understand the soil nutrient feature of asparagus field.The results demonstrated that pH was high ,both soil organic matter and available K contents were at medium level. The available P content in soil was deficient. There was a reasonable Cu and Fe content, whereas Zn,Mn and B contents of soil were low. The cation exchange capacity was low too and the ability of keeping fertilizer was weak.
